Smoke ConnectFX: The Keyer Nodes

first_imgThe Modular Keyer inside of Action or in ConnectFX does all of this for you. There are presets for each of these keyers that have the nodes added and linked up.  You can then add or delete nodes to get the best result for your individual keying situation.The Modular Keyer is the default keyer inside of Action.  It’s complex enough that it deserves it’s own blog post, so I’ll do no more than introduce it here.  Basically, it allows you to have a mini-schematic for keying inside of your larger ConnectFX setup.Smoke’s Master Keyer Node:Your first stop when you have a chroma key to perform, is the Master Keyer. Its name is appropriate as it contains a very powerful and interactive keyer with more tools to generate a clean key than any of the other keyers. By keying with the Master Keyer, you have tools for color supression, correction, and degrain built inside the node.  There are also Secondary Keyers, called Patches.Once you have your Front/Back/Matte feeding the node, you have a standard color pot for choosing your chroma key color. The Master Keyer has 2 pots so that you can chose slightly different areas, brighter and darker, and then allow you to mix between the 2 to get a good balance for the key overall. Instantly you can see how well the key is working by looking at the matte output (Press F4 twice).Your key probably isn’t perfect and there might still be some issues to work on. Here is where the Master Keyer excels.  By holding ALT and clicking in the viewer, will see a Heads Up Display (HUD) that allow you to adjust the key.  Depending on where you click in the viewer, you will get different option sliders (Matte Overall, Shadow Highlights, Ranges A,B,C,D,E),  These are smart sliders, as the Master Keyer is looking at the pixels underneath and giving you options to fix just those range of pixels. It’s very specific. Adjusting the sliders in context allows you to have real control over the key result.But sometimes you have a real problem key.  This is where the Master Keyer’s Patches come into play. Think of them like secondary keyers, similar to secondary color correction in the Color Warper.  Activate the patch by selecting it in the sampling menu. Then perform a Control+Box Selection in the viewer over a particular area you want to clean.  The Patch will analyse the pixels and assign them as white or black. Obviously it knows from previous selections that if you click to clean up an area that is currently a matte, it will fill in the pixels as white and an area that you want removed, it will make them black.You have 3 patches to work with, so you can easily clean up areas both inside and outside your matte.  The range and softness values for the patches are keyframeable. So if you have an area of you key where the lighting changes, and more shadows are introduced, you can adjust the values to compensate as the scene changes.Once you have the matte looking its best, you can now focus on the edges. Under the Color Menu, You can adjust the luminance and size of the edge. There is also a color wheel to skew the hue to better match into your background colors. For example, if you were keying your subject over red bricks, you would adjust the luma to match the brightness of the bricks and dial in a bit of red to match. This will help make your composite more realistic by blending the edges. You can also use the viewer interactive approach by selecting Blend from the Sampling Menu.The Master Keyer will also do color suppression and remove spill on your image. The color is copied from the initial key selection, but further adjustments can be made in the hue and range. You can choose to turn off the Auto CC as well by deselecting the button.  You would then need to add a Color Curves Node after the Master Keyer Node to suppress the color then.  More than likely, you can just use the internal suppression in this node.The output of the node is selectable. The result matte is always sent through the matte output, but the front can be selected to be the result with the background clip, the color corrected front without the back, or you can feed the matte output through the front. This flexibility gives you the options to add effects nodes downstream in your schematic and composite the key down the line.Keying on the Timeline:Sometimes while editing you need to get the cuts and timing down of your talent in Chroma Key as they pertain to the script or story. You can use the same keying tools from CFX on the timeline via the AXIS effect…with a few differences. If you place your chroma key talent on V2 with the background on V1 you can add an AXIS timeline effect to the chroma key.Inside of AXIS, activate the Keyer and you will see a new UI which combines all of the keyers we have talked about thus far, along with color and matte tools, histograms, and Gmasks. All in once neat and friendly package.  Since all the the keyers are independent, you can test each one and see which one works best for you right in the timeline and you can toggle back and forth.The color blend and spill suppression is available with each keyer as well as matte tools for shrink, erode, blur and invert. The histogram can be used to clamp the high and low values to clean up the key even more.Also, having the Gmask (Garbage Mask) tools at your fingertips makes trimming off bad sections of the scene and highlighting just what you want, can save you time when generating a good key.Once you have your key the way you like, exit AXIS and return to the timeline. Now, if your scenes are all the same, you can copy the AXIS effect to your other clips, adjusting Gmask as needed.  If you want to take this into ConnextFX for some more advanced effects, you can do that as well. Select your layers (Chroma Key & Background) add a CFX and make sure ‘Generate Composite’ is selected. Smoke will then take the effects you have setup already on your timeline and promote them into nodes inside of ConnextFX…with a few issues.The AXIS effect will become an Action node and the keyer inside will be the same keyer from AXIS.  The  keyer in Axis works great in the timeline with 8, 10 and 16 bit clips. But, if you are working with 10 or 16 bit clips then the keyer in Action will become inaccessible (black K).The keyer in Action (promoted from AXIS) only works with 8 bit clips. The default Modular Keyer in Action, if you activated a new Keyer setup, is 16bit. If you have any clips that are 10>16 bit, you need to activate the RGB Lut and convert them to 8 bit. Then the keyer in Action will become active (white K).  The keyer in AXIS used to be the same keyer in Action, but with the changes to the workflow in Smoke 2013, everything in CFX is processed at 16 bit fp.  This is one reason the Modular Keyer is being used as it already worked in 16 bit.  If you are working with all 8 bit clips on your timeline, then everything will be fine when you promote your timeline effect to CFX.Keying is one of the strongest features inside of Smoke. I personally do a lot of green screen work in the promos and commercials I edit. So I have gotten pretty good and pulling a good key even from compressed formats like H.264, DVCPRO HD, and AVC-I.  With better codecs and files like .r3D, and Prores4444 your ability to perform a good looking composite becomes very easy with the keyer tools in Smoke 2013. There are many keying tools inside of Autodesk Smoke 2013. So, how do you know which one to use and when?  We’ll breakdown the keyers so you can better decide which is best for your next project.Autodesk has always been known for their keying tools within their visual effects products.  Simply put, they have some of the best keyers in the business.  There are 7 keyer nodes inside of Smoke (Luma, Channel, HLS, RGB, YUV, RGBCMYL, Master Keyer).  If you want to include the Modular Keyer, which is a separate node-based keying environment, and the Diamond Keyer inside of the Color Warper, then you have 9 color keying tools.  Why so many? Well, Autodesk Flame is celebrating it’s 20th anniversary, and many of these keyers started then and there. Over time, other keyer algorithms have come along, each one a little different and a little better then the ones before. And since every keying situation can be different, sometimes one keyer can perform better and give you a better result then another.[Click on Images for a Larger View]The Smoke base keyers are the Luma, Channel, HLS, RGB, YUV, and RGMCMYL keyers. The Luma Keyer is a luminance based keyer, generating a matte from luminance levels.  The others are all color based keyers where you would select a color in the image to key out. In other words, a chroma key.  Each of these keyers only accept a front image and output a result image which is a hicon matte.The best chroma keyer inside of Smoke, in terms of features and quality, is the Master Keyer. The Master Keyer also accepts a Front, Back and Matte input and outputs a front and matte result. But we will focus on that keyer in a bit.Here is an example of how each of the base keyers treat this image when we do a simple 1 click color selection. Images provided by and available via HollywoodCameraWork.usEach of these chroma keyers (Channel, RGB, YUV, RGBCHML, HLS) has a color pot to select the color on the image you would like to key out.  You then have Tolerance and Softness tools to add/subtract color information to finesse the key result.  You can dial these values using the sliders or by selecting problem areas of the image.  Depending on the quality of your image, the lighting of your blue/green screen, shadows, compression, etc, each of these keyers may give a slightly different result. So often it’s good to try them all to see which one works for your given situation.The Channel Keyer works well when you have a very clean and uniform color channel to key. The other keyers work well when the image has impurities in the chroma key like shadows or creases in the background color.These nodes just give you the basic key, and result a matte. You would then need to add some other nodes like the Color Curves for color suppression on the edges or Edge Matte Nodes to add any shrink or erodes. Perhaps even a 2D Histogram to clamp the matte and clean up some rough areas, or even a Gmask Node to add a garbage mask to isolate a part of the image.  And ultimately, comp the front and result key together in Action or in the Blend & Comp Node with a background.last_img read more

A mentor is a skilled person who you admire in particular areas who agrees to come alongside you to help you grow in that specific area. Once you understand that concept you discover that it’s possible to have a number of mentors at the same time, each one contributing to your life in a specific area. So when should you seek out a mentor? Whenever you have an area of your life that you would like specific help with. On this episode of In The Arena, Claire Diaz-Ortiz shares insights from her new book, “The One Minute Mentor.”How can you find the best mentor for you?There are hurdles to finding good mentors, simply because those who are successful enough to serve you well as a mentor will also be the people who are already in high demand. Begin looking for a mentor by identifying your specific area of need and then observing who is in your circle who is strong in that area. Once you have a list of candidates, refine your own understanding of your need so you will be able to approach mentor candidates with clarity and precision when it comes to describing exactly what you’re looking for.

Amchang eviction drive draws flak from activists

first_imgIn a large scale eviction drive in the Amchang Wildlife Sanctuary in Guwahati in Assam, more than 400 families were evicted by police and Forest Department officials. The drive has generated severe discontent among the members of the Mishing tribe, which accused the State Government of resorting to “anti-people policies.”Local rights activists alleged that about 15 people were injured during the eviction drive as police resorted to large scale firing of rubber bullets and tear gas shells as well as baton charge. Commissioner of Police of Guwahati Hiren Chandra Nath denied the allegations. The eviction order was issued by Gauhati High Court during a suo motu public interest litigation in 2013.“Police and Forest Department officials evicted 408 families from the Amchang Wildlife Sanctuary in Guwahati. Fifteen people were injured due to indiscriminate baton charge and rubber bullet firing by police and four are in a critical condition,” local rights activist Ashraful Hussain told The Hindu.“The protest was totally peaceful and it was police who resorted to excessive use of force. The Assam government is claiming that the eviction drive was being conducted for the sake of preservation of wildlife, but it is nothing but shameless oppression of the poor,” said Priti Raj Doley, a member of the Mishing tribe and a leader of the Krishak Mukti Sangram Samity.last_img read more

Startup Playi using friendly robots to teach kids computer programming

first_img(Phys.org) —Startup Play-i has created a crowd-sourcing campaign to gather funds for building and selling its pair of robots called Bo and Yana—both are part of an overall toy design to teach children as young as five years old, to program a computer. The idea, the team says, is to get children interested in programming by making it a part of storytelling. Citation: Startup “Play-i” using friendly robots to teach kids computer programming (2013, October 29) retrieved 18 August 2019 from https://phys.org/news/2013-10-startup-play-i-friendly-robots-kids.html More information: www.play-i.com/ The two robots look and behave differently. Yana has three wheels and can roll around, it can also play its little xylophone if programmed to do so. Yana, which the creative team behind the robots calls the storyteller, is able to make different recognizable sounds on demand.The team behind Play-i is a collection of people who used to work for big tech companies such as Google, Apple and Frog Design. They started their company with the idea that children are capable of learning sophisticated concepts if they are presented in the right way. Bo and Yana are programmed using kid-friendly icons on a smartphone or tablet (since the operating system is iOS, that means iPhone and iPad, at least for now). To get either of the robots to do something, children develop a story around what it is they want done, then use the icons to develop the story, which results in the robots carrying out actions that follow what they’ve described. One example would be having Bo retrieve a flower from another robot, or a person, then carry it to someone else for presentation. Yana on the other hand can be taught to emit a sound like a helicopter if someone touches it. The concept is simple, by breaking down something that seems complex into something that is actually small parts of a story, children can develop more complex programs.The Play-i team is also looking to the future with their robots—code that is created from the icons is displayed on the tablet screen so that the child can see what they have wrought—as they grow older they can progress to writing code directly, giving them even more control over their toys.The crowd-funding campaign has a goal of collecting $250,000, if that number is reached, Play-i says the robots will be available for purchase by this summer, likely priced at $199 and $69 for Bo and Yana respectively.

ATM fraud case Probe reveals cloning of cards used to take place

first_imgKolkata: In a major revelation in connection with the ATM fraud case, the city police has come to know that the cloning of debit cards used to take place in a neighbouring country. The cloning of cards was done using details stolen from debit cards in Kolkata.The police have come to know about the information after the arrest of Adre Liviu and Cornel Constantine from Indore on Thursday.It has come to light that members of the Romanian gang used to install skimming machines in ATM counters in Kolkata. They used to remove the skimming machine after it had read details of some cards swiped at the ATM counter for any transaction. Also Read – Rain batters Kolkata, cripples normal lifeThey extracted the stored data from the skimming machines and sent the same to their counterparts in theneighbouring country to prepare the clone cards. It took them around two to two and a half months to prepare a clone card.The cards were then sent to members of the Romanian gang in Delhi and using the same, cash was withdrawn from different ATMs in Delhi.Preliminary investigation has revealed that Adre was the main person in charge of installing the skimming machines at ATM counters. Both Adre and Cornel were close associates of another Romanian national Nana, who was arrested from the Indo-Nepal border on Wednesday by Customs. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedHe was later handed over to Kolkata Police. The police had come to know about Adre and Cornel from Nana.The duo had realised that they would also get arrested after Nana was caught. So they were also trying to flee from the country. The car in which they were travelling was fitted with a GPS system and it enabled the police to track them with the help of Indore Police.Preliminary investigation has revealed that Nana and the duo had connection with their counterparts in the neighbouring country. A shop has also been identified in the neighbouring country, where the cloning of cards used to take place. A team comprising members of the Special Investigation Team (SIT) are in constant touch with the security agency in the neighbouring country and may visit the place to further probe the case.The arrested persons have been brought to Kolkata on Friday and they were produced before the Bankshall Court. The police suspect that there could be more people involved in the crime and officers in the SIT are trying to ascertain the same.last_img read more

4 Ways Personal Technology Outperforms Enterprise Software

first_img Growing a business sometimes requires thinking outside the box. 5 min read Opinions expressed by Entrepreneur contributors are their own. The freelance economy rapidly is growing in the United States. More than 15 million people are self-employed, and numerous experts predict we’ll soon see a steep increase in the number of individuals who leave corporate America to work for themselves. One study put the number at 60 million people by 2020 — nearly 40 percent of the workforce.Why are so many people making the switch, and which changing dynamics have made it possible? While no single answer explains the shift, we can identify a number of contributing factors. For example, we know employers see the benefit of hiring a contractor to perform specific functions for a limited period of time. It’s more cost-effective than hiring a full-time employee. We also know numerous platforms exist today to connect freelancers with available work. All this makes it easier than ever before to be self-employed.But other drivers are at play, too. Here’s one that might surprise you: There is substantial disparity in the technology capabilities of large corporations versus self-employed freelancers. According to enterprise software expert Sean Nolan, founder and CEO of Blink, personal technology currently has a substantial edge.“Enterprise software is far behind the standard being set by personal technology today,” Nolan says. “In fact, it is so bad that it is giving a competitive advantage to startups and freelance workers who are more productive, more satisfied with their work and able to operate their small businesses more cost effectively.”These are four ways personal technology is superior to present-day office technology:1. User friendliness.It might not be fair to compare personal and office technologies in this regard because they’re designed for completely different audiences. Still, that doesn’t justify how far behind the times office technology has fallen.Personal technology has the user in mind. Interfaces are clean and engaging, data is visualized in digestible ways, and many functions are gamified to encourage use. Taken as a whole, these systems make it more enjoyable to be in business for ourselves. We can hand-select the software that best suits our working preferences and style.“We are all conditioned by the technology we use at home, so when we go to the office and have a vastly inferior experience, that is hugely frustrating,” Nolan says. “It’s destroying employee productivity and retention.”Related: 5 Productivity Tools for Self-Employed Internet Entrepreneurs2. Mobile applications.Desktop computers are almost synonymous with “old technology.” But in many companies, it’s the only device an employee has to do his or her job. We’re confined by that workstation and the very limited software installed on our system. By contrast, home-office technology is typified by its flexibility.Freelance professionals work from their phones, tablets and laptops while they travel on planes and trains. They get things done in cities around the world. They’re able to do so because their work programs feature excellent applications. They can access the files they need from any device, and they all connect to the same information stored on the cloud.Apart from the frustration of working on an outdated console, employees who are limited by old technology are less effective in their roles. They cannot work unless they’re at their desks. The workforce — and millennials, in particular — demand a better work-life balance. Mobile applications allow employees to be effective anywhere they go.Related: 5 Ways to Be More Mobile-Friendly in 20173. Customization.Everyone has different needs depending on the job they perform. Naturally, this means they need access to different kinds of information and tools. Here again, personal technology outperforms enterprise technology.“At home you can change the settings on all of your applications and devices to help you do your job most effectively,” Nolan says. “But the average user of enterprise software is confined to limited, preset options. A large percentage of the workforce cannot even access job-critical information without the help of other employees.”Of course, enterprise software is designed to be big, which makes it difficult to be customizable on a user-by-user basis. Even so, a wealth of new technologies can assist with that problem. Bots, micro apps and chat functions are a few of the solutions for large-scale employers looking to improve user experience.Related: How Technology Rapidly Is Changing the Way Things Get Done Across Industries4. Artificial intelligence.It’s hard to write anything about artificial intelligence (AI) that hasn’t been covered elsewhere, but we can’t ignore it, either. Personal technology already incorporates AI into numerous software products freelancers use to do their work. From sales and marketing platforms to billing and accounting technologies, these systems all use AI to exponentially increase productivity.The corporate world has been slow to adopt AI for its own use. It needs to embrace the functionality that AI can deliver or risk falling further behind. According to an MIT study, only 38 percent of CEOs list technology renovation among their priorities.Related: The Growth of Artificial Intelligence in EcommerceWhat might push enterprise-technology enhancements higher on the agenda? An exodus of high-quality employees from the corporate world might get some attention. When the best professionals prefer to freelance their talent, executives must take stock of the fundamental differences between working for a company and working for oneself. Technology has to be a factor. Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global January 26, 2017 Register Now »last_img read more

Billy Bishop Airport introduces enhanced screenings for ferry passengers

first_img Posted by Share << Previous PostNext Post >> Billy Bishop Airport introduces enhanced screenings for ferry passengers Tuesday, March 13, 2018 center_img TORONTO — Billy Bishop Toronto City Airport (YTZ) has implemented new enhanced security procedures that may require passengers to go through random screenings.Effective immediately, the new procedures were put in place by Transport Canada under the Domestic Ferry Security Regulations. According to the airport, this may result in random baggage/belongings checks of some passengers for the presence of explosives.“The random screening will be completed by swabbing the exterior of the baggage and/or belongings and analyzing the swab taken with a portable detection device,” said the airport on its website. “Passengers may expect to be approached by Billy Bishop Airport Security staff to participate in the screening process prior to boarding the ferry.”Passengers can also access the airport via the pedestrian tunnel that connects the facility to the mainland, however the airport has yet to confirm whether the security screenings will be applicable to this access point as well.More news:  Honolulu authorities investigate arsons at 3 Waikiki hotels; no injuries reportedThe last time YTZ updated its security measures was in July 2017 when it was authorized by the Canadian Air Transport Security Authority (CATSA) to conduct a secondary search and/or additional screening of electronics the size of a cell phone or larger.
