Customize Default Effects in Final Cut Pro X

first_imgApple’s recent Final Cut Pro X update includes a convenient new feature that allows users to easily assign default audio and video effects to their clips using a simple keyboard shortcut. Let’s take a look at how it works.With the latest version of Final Cut Pro X, Apple is certainly not attempting to reinvent the wheel. For the most part, the update includes bug fixes, performance enhancements, and other new features, such as the ability to output to multiple YouTube clips at once. But one of the more interesting additions to 10.2.3, one that will make certain editorial tasks easier and more convenient, is Final Cut Pro X’s ability to customize default effects.Many of you are probably already familiar with Final Cut Pro X’s default transitions as a result of using the shortcut CMD+T. With a clip selected, this will automatically apply a cross dissolve, giving editors a very fluid method for applying a transition without using their mouse.Some of you probably also know that you can right-click on any transition in the Transitions Browser and set it to your default. So for example, if you want to use a wipe transition on multiple clips, you can replace the cross dissolve transition with a wipe, allowing you to make use of your keyboard shortcut.With the latest version of Final Cut Pro X, you can do the same for color or audio effects. By default, Final Cut Pro X will now apply a basic color corrector to your clip when you hit Option+E and will apply a channel EQ to your audio when you hit Command+Option+E.Default Transition = Command+TDefault Color Effect = Option+EDefault Video Effect = Command+Option+EMuch like how default transitions work, you can set any color effect or any audio effect to be the default setting, effectively overriding the current presets. For instance, if you often need to use a black-and-white color effect to preview a certain look, it might be worth assigning that to your keyboard shortcut as a means to quickly see how a clip will work in monochrome. Alternatively, you might want to add some reverb to a bunch of your audio tracks for stylistic effect, and can do the same using this method.For a quick demo on how this works, check out this video from Ripple Training, which outlines the new feature:What’s your favorite default transition?

Match-fixing episode affected my game: Sachin Tendulkar

first_imgSachin Tendulkar has for the first time admitted that the match-fixing episodes in 1999-2000 had initially affected his game and the Indian team had to go through a difficult and painful phase as “spectators looked at us with suspicion”.Tendulkar said he was not in the right frame of mind during India’s disastrous tour of Australia where they were thrashed 0-3 in 1999-2000.”I can tell you that I was never approached by anyone, neither we had any discussions about the same in the team meeting,” Tendulkar told former South African Board President Dr Ali Bacher in an interview for Super Sport Channel.”I remember that there was a stage in 1999-2000 when it was very difficult as we were to play Australia. Before the series these things started making rounds. As a cricketer that’s the last thing I want.”You want your beloved game to be as clean as possible. I wanted the spectators to enjoy the contest and not look at us with suspicion. To play well, players need to be in right frame of mind and I can tell you that I was not in that frame of mind,” Tendulkar said, recollecting the disastrous series.The pain in his voice was evident as he gave the interview. “Every match you play and people pass on loose comments. This was really hurting me and the whole team,” said the maestro.Tendulkar felt that their historic 2-1 series win over Australia at home was the turning point. “I was sure that we needed to put up a very special performance against Aussies so that cricket lovers forget what has happened in the past and start enjoying the game again and move on. With grace of God we managed to do that.advertisement”We lost the first match at Mumbai. But in the next match at Kolkata we fought back from very bad position and won that match to level the series. Last match was even harder. At Chennai while chasing small total we lost eight wickets but won that Test match and series too.”I was happy for the fact we forced cricket lovers to forget about that bad chapter and start following cricket again.”Recollecting the horror days of match fixing, Bacher revealed that the South African Board was indeed approached by bookmakers.”We were directly approached by bookmakers to take their offer to the players through team meeting. Those were days when in couple of ICC meetings, I had raised this issue,” he said.With inputs from PTIlast_img read more

Seven Generations shares slide after it increases 2018 capital spending plan

first_imgCALGARY – Negative market reaction to a slight rise in its 2018 spending plan by natural gas producer Seven Generations Energy Ltd. (TSX:VII) shows how little patience investors have for anything but conservative management in the oilpatch, analysts say.On Thursday, shares in the company plunged by as much as 10 per cent after it announced it would increase its budget by five per cent to about $1.75 billion next year compared with 2017. The stock closed at $16.58, down $1.37 or nine per cent from Wednesday.The reaction was in sharp contrast to the eight per cent rise in shares of Tourmaline Oil Corp. (TSX:TOU) on Nov. 9, the day after it announced it would chop its 2018 capital budget by 29 per cent to $1.08 billion from the previously planned $1.52 billion because of low gas prices.Both Calgary-based companies produce liquids-rich natural gas from wells near the sparsely populated northern Alberta-B.C. border.“I think the capital discipline within the sector seems to be getting some traction, the focus on capital allocation and returns rather than growth,” said National Bank Financial analyst Travis Wood.He said he was surprised at the Seven Generations selloff because its 2018 budget was very close to analyst forecasts and its production next year is expected to be only slightly reduced by ongoing outages at a third-party gas processing plant.Seven Generations CEO Marty Proctor said at the company’s investor day on Thursday it will “outspend” cash inflows in 2018 to increase production and complete construction of a new gas plant but will return to a balanced budget in 2019.“We are targeting cash flow self-sufficiency — that is, a balanced budget — in 2019,” he said. “We are targeting continued profitable growth … by around 100,000 boe/d to reach 300,000 boe/d by 2022.”The company plans to grow its output by around 15 per cent to roughly 205,000 barrels of oil equivalent per day in 2018, with 55 to 60 per cent natural gas liquids.Tourmaline, meanwhile, cut its production target range for 2018 to a midpoint of 275,000 boe/d from the previous 290,000 boe/d, containing about 16 per cent liquids.“The company has elected to moderate growth in its natural gas business until the Western Canadian and North American supply/demand outlook is more transparent and balanced,” it said in a news release.Wood said investors were likely also attracted to Tourmaline’s introduction of a modest dividend of eight cents per quarter.“We have noted a strong theme of budgets funded by internally generated cash flows which is resonating with investors, and which differs from the previous mantra of ‘growth at all costs’,” wrote RBC analyst Michael Harvey in a report earlier this week.“However, we do expect upward revisions to most company budgets if commodity prices and access to capital improves in the medium term.”RBC said it believes Western Canadian producers will spend about seven per cent less in 2018 than in 2017 but production will increase by about 15 per cent as accelerated drilling in the fourth quarter comes on line early next year.Follow @HealingSlowly on Twitter.last_img read more

NFL Week 4 Elo Ratings And Playoff Odds

Before scrolling down and peeking at the table, take a guess: Which team has the highest projected end-of-season win total according to FiveThirtyEight’s latest NFL Elo ratings and playoff odds?While you’re thinking, let me briefly explain what these numbers are all about. A team’s Elo rating represents its current strength — or at least an estimate thereof using a simple method that incorporates margin of victory, home-field advantage, strength of schedule and team quality in previous seasons. (For the really gory details of how the ratings work, click here.) To give you a sense of the scale, the average NFL team always has an Elo rating of 1500, and the ratings usually range from 1700 on the high side to 1300 on the low end of the spectrum.Anyway, once computed, they can be used to derive win probabilities for each game and even point spreads. That’s how we’re able to simulate the remainder of the NFL schedule thousands of times and track each team’s chances of winning the division or making the playoffs, right down to using the NFL’s actual, highly arcane tiebreaker rules.OK, so now that the explanation is out of the way, which team has the most predicted wins?Perhaps you’re thinking of the Seattle Seahawks, who won their Super Bowl rematch with the Denver Broncos on Sunday afternoon. You’d be close; Seattle once again checks in with the top Elo rating this week (see left), but their schedule is difficult enough — eighth-toughest in the league, to be exact — that they don’t have the league’s highest expected win total. Speaking of the Broncos, they had the most predicted wins in last week’s column, but their loss to the Seahawks was damaging — both because it took away about 0.38 expected wins for the Seattle game itself, and because their Elo rating was downgraded by 14 (or the equivalent of a little more than a half a point of victory margin per game), reducing their win probabilities in future games as well.New England, then? The Patriots did manage to win last week but only marginally improved their Elo rating after a seven-point victory over the Oakland Raiders in a game Elo thought they should have won by more than two touchdowns. They currently rank fourth in expected wins. And the Carolina Panthers, who had been pegged for 10.7 wins after a 2-0 start, dropped to a 9.1-win expectation in the wake of an 18-point home loss to the Pittsburgh Steelers.The answer you were looking for was actually the Cincinnati Bengals, who project to win a league-high 11.2 games, according to our simulations. The Bengals moved to 3-0 for the first time since 2006 (don’t ask what happened that year) by drubbing the Tennessee Titans 33-7, and they now have the NFL’s best point differential. They also have an easier remaining schedule than the teams above them in the Elo pecking order. Based on Elo, an average team would be expected to beat Cincinnati’s remaining opponents by about 0.1 points per game (taking into account where the games are being played), while an average team would lose by 0.6 PPG against Seattle’s slate, 0.4 PPG against Denver’s and 0.2 PPG against New England’s.The Bengals also have the league’s best playoff odds at 78 percent and its second-best shot at winning the Super Bowl. Cincinnati does not have the best division odds, thanks to the re-emergence of Pittsburgh and Baltimore (sorry, Cleveland). Before the season, we thought the AFC North would be up for grabs, and three of its teams had preseason Elo ratings above 1500, but they were all bunched at the fringe of the top 12. Now Elo’s fourth-, ninth- and 12th-best teams hail from the AFC North, making it the NFL’s second-best division (in terms of its members’ average rating) behind the fearsome NFC West.Either way, Bengals fans should enjoy their team’s newfound success. They’re in a relatively prosperous cycle of the franchise’s history; including the end of last season, the team is consistently producing its best Elo ratings since the end of the 2005 season. Let’s hope there isn’t another Kimo von Oelhoffen moment waiting to derail the momentum this time around.Here are the projected standings and playoff odds for every NFL team:Some other observations:After briefly pulling themselves up to a 1503 Elo with a win over the New York Jets in Week 2, the Green Bay Packers dropped below 1500 again and now have their worst rating since the beginning of the Aaron Rodgers era. It’s a far cry from the Packers team that boasted a 1780 Elo late in the 2011 season, just 145 short weeks ago.Like Cincinnati, the Arizona Cardinals are zooming up the expected-win charts. Our simulations have them winning an average of 10.6 games by the end of the season, which ranks third in the league. Interestingly, by Elo they aren’t even the second-best team in the NFC West — San Francisco is barely ahead despite losing to Arizona last week — but they are expected to win 1.8 more games than the 49ers because they are already two games up in the standings (though they play the fourth-hardest schedule in football from now on).San Diego shouldn’t be forgotten in the Super Bowl derby. Although the Seahawks are the clear favorites, with a 14 percent chance of winning it all, the Chargers are at the periphery of the next tier of contenders — a group that also includes Cincinnati, New England, Arizona, Denver and possibly the Philadelphia Eagles. And along with the Bengals and Cardinals, the Chargers have added the most to their Elo score since the preseason ratings, improving from a 1555 to their current 1602 mark over the course of three straight victories.Although their 1999 incarnation was pretty extraordinary, the 2014 St. Louis Rams — along with the Tampa Bay Buccaneers and Jacksonville Jaguars — seem to be deteriorating. No teams have shed more points off of their Elo ratings since the season began, with each losing in excess of 49 points (the equivalent of about two points per game of expected scoring margin) compared to their preseason ratings.As I mentioned, Elo ratings can also be used to generate point spreads for future games. It is our staunch recommendation, however, that these be used for “entertainment purposes only” — especially after a performance like last week. Going up against the point spreads listed at Pro-Football-Reference.com, Elo’s picks were a dreadful 4-11-1 in Week 3. (They did have a 12-4 straight-up record.) But we’ll soldier on anyway and list the matchups for this week, along with their predicted win probabilities and point spreads:The best matchup of the week in Elo’s eyes is Philadelphia at San Francisco, which matches Nos. 6 and 10 in our rankings. But as far as marquee games go (measured by the harmonic mean of the two teams’ pregame ratings after adding half the home-field advantage to each side), it’s the worst week-leading matchup of the season yet.Even so, there are some interesting pairings to be had, in addition to Eagles-Niners. Elo considers Washington and the New York Football Giants to be a classic “pick ’em“, while Vegas sees Washington as three-and-a-half point favorites, perhaps underestimating just how bad of a period this is in the franchise’s history. Likewise, Green Bay is a one-and-a-half point favorite at Chicago despite Elo pegging the Bears as five-point favorites. How much of that is owed to the Bears’ banged-up defense, and how much simply stems from a refusal to believe the Packers aren’t the same team they were several years ago, is tough to say.Finally, a couple of NFC South teams are getting a lot more love in Vegas than the ratings say they deserve. The books have both Atlanta and New Orleans favored by 3 on the road this week (the Falcons visit Minnesota; the Saints go to Dallas), while Elo thinks Vegas is off by about 5 points in each matchup — enough to swing the expected winner of both games. In general, Elo has the NFC South as the fifth-best division in football, but if both teams buck the odds and live up to those spreads on the road, our computer might have to change its tune. read more

Gracia I prefer to speak about the penalty

first_imgWatford manager Javi Gracia deflated talks on the controversial decisions that marred his side’s 1-1 draw with Southampton at St Mary’s on Saturday.The Hornets came from behind to secure a draw on the south coast, which saw Gracia’s side climb above Manchester United into seventh on goal difference in the Premier League.“I prefer to speak about the penalty,” the Spaniard disclosed to Sky. “It was first when there were more than 30 minutes left, it could be the second yellow card for that player, a penalty and after that, maybe the game could change.“I didn’t see it from my position, it’s impossible to know what happened.What to expect from Watford V Arsenal? Taimoor Khan – September 8, 2019 Arsenal are set to take on Watford this weekend and the game is definitely going to be quite a peculiar contest between two sides…“But after asking Chalobah he told me it was clear and maybe changed the game from that moment. But I prefer to support the referee’s decision, it’s difficult their job.”Gracia thought it was a fair result after his team rallied round for a point.“We have won a point,” he said. “It is true, we were improving and at the end of the game we created some chances to win. But I think a draw is fair and Southampton created some chances to score in the first half as well.“And we tried to compete and in the second half we showed character and ambition to get this point and it is important after the game we played today to go back home with one point.”last_img read more

Republicans Expected To Revise Texas Bathroom Bill

first_img Share Todd Wiseman / The Texas TribuneState Sen. Lois Kolkhorst and Lt. Gov. Dan Patrick unveil the text of Senate Bill 6, which would require transgender people to use bathrooms in public schools, government buildings and universities based on “biological sex,” on Jan. 5, 2017.With the measure scheduled for a committee hearing Tuesday, Texas Republicans are expected to offer a new version of the controversial “bathroom bill” with two significant changes.The modified bill removes a section that would have increased penalties for certain crimes committed in a bathroom or changing facility, according to a copy of a committee substitute obtained by The Texas Tribune. It also adds a new “legislative findings” section that would write into statute the reasoning that the bill’s lead author, Republican state Sen. Lois Kolkhorst, has provided in pushing for the bill.Senate Bill 6 would require transgender people to use bathrooms in public schools, government buildings and public universities that match their “biological sex.” The measure would also pre-empt local nondiscrimination ordinances that allow transgender residents to use the bathroom that matches their gender identity.Those regulations are largely unchanged in the substitute language expected to be presented tomorrow, but the modified bill does not include a lesser-known section that would have increased penalties for certain crimes in bathrooms by one degree. That would have meant that the punishment for an individual who commits an assault, for example, would have been higher if the assault occurred in a bathroom versus a parking lot or on a sidewalk.The new “legislative findings” section appears to be intended to lay out the purpose of the bill. That section states that the “federal government’s mandate to provide students access to bathrooms, showers and dressing rooms based on an individual student’s internal sense of gender is alarming and could potentially lead to boys and girls showering together and using the same restroom.”That appears to be an apparent reference to since rescinded guidelines issued by the Obama administration that directed public schools to accommodate transgender students. The Trump administration pulled back those guidelines on Feb. 22.The “legislative findings” section goes on to explain that “it is the public policy of this state that residents have a reasonable expectation of privacy when using intimate facilities” controlled by governmental entities and that “protecting the safety, welfare, and well-being” of children and Texas residents “in intimate facilities” controlled by the government is “of the utmost priority and moral obligation of this state.”That echoes previous arguments made by Kolkhorst and Lt. Gov. Dan Patrick, a champion of the bill, who insist the legislation is meant to increase privacy and the safety of women in “intimate settings.” Opponents of the bill, including LGBT advocates and parts of the Texas business community, have decried the bill as discriminatory, particularly as applied to transgender students in public schools.The Senate State Affairs Committee is set to take up the legislation on Tuesday morning where Kolkhorst is expected to lay out the committee substitute. Her office did not immediately respond to a request for comment regarding the substitute.More than half of the Senate has signed on in support of the measure, which is likely to face opposition in the Texas House.As of Jan. 30, 14 other senators had endorsed Kolkhorst’s bill and signed on as co-authors. On Tuesday, state Sen. Eddie Lucio Jr. — a Democrat from Brownsville — also announced his support of the bill, and two more Republicans — state Sens. Konni Burton of Fort Worth and Charles Schwertner of Georgetown — were added to the list of co-authors, bringing to 18 the number of Senators on record supporting SB 6. Under Senate rules, 19 senators are needed to bring up a bill in the chamber.This article originally appeared in The Texas Tribune at https://www.texastribune.org/2017/03/06/republicans-expected-tweak-texas-bathroom-bill/.Texas Tribune mission statementThe Texas Tribune is a nonprofit, nonpartisan media organization that informs Texans — and engages with them — about public policy, politics, government and statewide issues.last_img read more

New Police Chief Is Making Efficient Changes To HPD

first_imgListen X 00:00 /01:11 To embed this piece of audio in your site, please use this code: Michael HagertyHouston Police Chief Art Acevedo.Houston Police Chief Art Acevedo has mentioned several times how under staffed the police department is.“We’ve grown in 20 years by 500,000 residents, yet we have 300 fewer officers. I don’t know the number,” Acevedo says.That is why they are taking steps to become more efficient.Acevedo announced they are putting a time limit on how long the disciplinary process can take, reviewing the paperwork process to ensure there is no duplications, and creating a 911 system that can tell an officer if a person has some sort of impairment like autism or dementia, so that the officer can handle the situation accordingly.  In order to do all these things efficiently, Acevedo says the department most rely on data. “We have to look at data we have to be data driven and intelligence led,” Acevedo says.He also mentioned focusing on non-fatal shootings.“When you discharge a firearm, we’re not going to wait until somebody dies,” Acevedo says. “We are going to respond with investigators, with detectives to start working those nonfatal shootings as if they were a homicide.”Acevedo is advocating that the city’s cap on how much they can collect from property taxes is lifted so that the department can purchase more resources and become better staffed.

Driven by Streaming Global RecordedMusic Revenues Soar to 191 Billion

first_img Popular on Variety The global recorded music market grew by 9.7% in 2018 — its fourth consecutive year of growth — to $19.1 billion, according the latest annual report from the International Federation of the Phonographic Industry (IFPI).Streaming revenue grew by 34.0% and accounted for almost half (47%) of global revenue, powered by a 32.9% increase in paid subscription streaming, according to the report. There were 255 million users of paid streaming services at the end of 2018, with paid streaming accounting for 37% of total recorded music revenue. Growth in streaming more than offset a 10.1% decline in physical revenue and a 21.2% decline in download revenue.Streaming in North America was up by 14%, though that was down from 2017’s 17.1%.Looking at individual markets, for the fourth consecutive year, Latin America was the fastest-growing region (+16.8%) with Brazil (+15.4%) and Mexico (+14.7%) growing strongly. The Asia and Australasia region (+11.7%) grew to become the second-largest region for combined physical and digital revenue, with especially strong growth in South Korea (+17.9%). Drake Tops IFPI’s 2018 Best-Selling Artist List Related The top 10 markets are, in order, the U.S., Japan, the U.K., Germany, France, South Korea, China, Australia, Canada and Brazil.The IFPI previously named Drake as the biggest recording artist of 2018, while “The Greatest Showman” was the top-selling album and Camila Cabello’s “Havana” was the biggest global single of the year.“Last year represented the fourth consecutive year of growth, driven by great music from incredible artists in partnership with talented, passionate people in record companies around the world,” said Frances Moore, chief executive of IFPI.“Record companies continue their investment in artists, people and innovation both in established markets and developing regions that are increasingly benefitting from being part of today’s global music landscape.“As music markets continue to develop and evolve, it is imperative that the appropriate legal and business infrastructure is in place to ensure that music is fairly valued, and that the revenues are returned to rights holders to support the next cycle of development.” ×Actors Reveal Their Favorite Disney PrincessesSeveral actors, like Daisy Ridley, Awkwafina, Jeff Goldblum and Gina Rodriguez, reveal their favorite Disney princesses.

NTT researchers develop breakthrough optical memory device

Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission.

Nevertheless, it constitutes a key device in optical routing and processing. Here, we demonstrate that photonic crystal nanocavities with an ultrasmall buried heterostructure design can solve most of the problems encountered in previous o-RAMs. By taking advantage of the strong confinement of photons and carriers and allowing heat to escape efficiently, we have realized all-optical RAMs with a power consumption of only 30 nW, which is more than 300 times lower than the previous record, and have achieved continuous operation. We have also demonstrated their feasibility in multibit integration. This paves the way for constructing a low-power large-scale o-RAM system that can handle high-bit-rate optical signals. Journal information: Nature Photonicscenter_img All computer memory is based on a material that is able to have 1s and Os written on to it and held in such a state long enough to be useful. Also necessary is an ability to erase or write over those 1s and Os so that the same memory material can be used over and over.The new memory device created by the NTT team relies on optical cavities that are created in a material that can be made to represent 1s and Os by either transmitting light, or by blocking it.To make the memory cell, the team buried a very tiny strip of indium gallium arsenide phosphide in a small piece of indium phosphide. The outer portion was then etched with holes small enough to control the flow of laser light of a certain frequency. They left a path running though the middle of the material un-etched to provide a means for light from a laser to move in and out of the cell.When laser light is shone on the material, it follows the path through the memory cell and the refraction index is changed causing a pulse of light to either pass through on not, representing either a 1 or O state. Another pulse changes it to another state and so on. To help the memory material maintain its state, a second laser provides a constant stream of background light.The memory cell was able to hold onto the state it created for a microsecond, which quadruples the old record and it also uses far less energy than conventional designs. A memory chip with four of the optical memory cells consumes just 30 millawatts of energy, whereas common use flash drives use five times that amount.But the real breakthrough here is the development of actual memory cells based on optics that are able to hold onto the data states they create long enough for them to be used by other parts of a hardware device. And while the memory cells are far too large to be of use right now, new designs based on this work might just lead to that elusive Holy Grail, an Internet backbone made entirely of optical components. Engineers at Yale develop new type of mechanical memory (PhysOrg.com) — To improve transmission speeds, the Internet has transitioned over the years from one using copper to fiber optic cabling. Unfortunately, this has caused a bottleneck to occur where the light signals meet with electronic circuitry. Researchers have been working for years on a way to make routers, and most particularly, their memory, all optic, to avoid having to convert the signals at all. Now, it appears one such group, NTT, a Japanese telecommunications company, has figured out a way to do it. They describe their work in a paper published in Nature Photonics.
