【插件介绍】 由于我们肉眼和摄像几捕捉的光线频率不一样,所以我们有时候用摄像机捕捉的视频会出现光闪烁的现象, Digital Anarchy Flicker Free v1.1 插件能就能帮助我们弥补这一缺陷,能够很好的处理光闪烁的现象:光闪烁,延时拍摄闪烁,动态闪烁。 解决做延时摄影或拍摄慢动作(高帧速率)视频产生的闪光。同时这也是非常有效的去除LED灯,电脑显示器或当有电气干扰时产生的闪烁。 插件从分析画面的颜色和亮度从而计算匹配出平滑的视频图像。 Flicker Free is a powerful new way to deflicker video. It solves an issue that’s common for many types of footage, be it from lights/electricity and cameras being out of sync, time lapse or slow motion (high frame rate) video. It’s very effective at removing rolling flicker that occurs with LED & fluorescent lights or computer monitors. Flicker Free was originally designed to fix the flicker caused by varying exposures in time lapse videography.
However, once we developed it, we discovered there are many reasons for flicker and that Flicker Free does a great job on most of them. 官网:支持软件: (Win64) Premiere Pro CS5, CS5.5, CS6, CC, CC 2014,CC 2015 After Effect CS5, CS5.5, CS6, CC, CC 2014,CC 2015 【插件下载】 插件为一键安装破解版,安装即可使用,无功能限制 本文固定链接.
Presets for an Easy Workflow They make it easy to get the right settings very quickly, without reading a huge manual. Dramatical murder reconnect game download. Plugins should just work.
There are several presets for different types of video footage. These are settings we've found to work well in our tests. At best, they'll instantly solve your flicker problems!
(this happens a lot so try one of the presets, it may be all you need to do) Otherwise, they provide a good starting point and you shouldn't need to make too many tweaks. Every piece of video footage is different, of course, but the types of flicker tend to be the same. So the presets usually work quite well. Easy to Understand Video plugins should make your life easier. The software should be doing the hard work behind the scenes so you can get work done quickly without watching hours of training videos. Flicker Free is a critical video plugin when you have footage with flicker problems, but hopefully you won't need all the time. It's good to know you can just pull it out of your toolbox and it'll just work.
There's no need to re-learn complicated parameters every time you use it. Analyzes on the Fly Flicker Free doesn't require any 'pre-analysis' to work. Just apply it to your footage, render a couple seconds as a test and you're ready to render your entire project. It analyzes the frames as it's rendering so you don't have to wait around before you can get to work.
Deflicker Time Lapse Footage A time lapse video requires taking a photo every 1 second or 1 hour and combining them to make the video. This can result in beautiful videos, but the problem is that the lighting changes. This causes the camera to adjust the exposure and you get flicker. Flicker Free was designed to deal with Time Lapse flicker and works beautifully on it. Slow Motion Footage Many lights will cause flicker in slow motion footage. Normal lights running on AC (Alternating Current) can fluctuate in brightness as the electricity fluctuates (the 'alternating' in AC).
These fluctuations in brightness can affect your footage if the camera is shooting 120fps or faster. The higher the frame rate of the footage the more apparent it is. This can happen regardless of whether you're shooing with a Phantom Flex, Sony FS700U or GoPro HERO3 Black (shoots 240fps). Flicker Free will smooth out the fluctuations and make the brightness consistent throughout the video clip. There are lights that don't flicker. They're more expensive and probably well within your budget if you're using a Phantom.
However, with many high speed cameras available in the $5-10K range (Sony FS700U, Edgertronic, etc), budgeting another $4K for lights might not be feasible. So, go grab some $25 tungsten shop lights from Home Depot and use Flicker Free! LED Lights Most people don't realize that many LED lights have a refresh rate similar to that of a computer monitor. If you're camera isn't in sync with the refresh rate, you'll get rolling bands going through your video.

This is one of the more common flicker problems we've seen as many places have switched to LED lights but it's not obvious to production people when shooting. You don't discover they're LED lights until you get the footage into post and see all the flickering. Luckily Flicker Free is there to help! It saved some of the shots on this music video by the Bloody Beetroots and Tommy Lee. Archival Footage If you're restoring older footage, flicker comes from a few sources. 1) The film may have degraded over time, 2) The camera was hand cranked making it difficult to maintain a consistent exposure over the course of the shot, and 3) older lights were more prone to flickering.
If the problem comes from Exposure, which would've been in the original, then it’s a similar problem to time lapse. It effects the whole frame and should be easy for Flicker Free to fix. It'll look better than it ever did!

For future reference, it appears there are three FCPX plugins which do this: Seed De-Flicker ($25): BorisFX Flicker Fixer ($299, part of their Image Restoration package, not sure if it's available separately): Digital Anarchy Flicker Free ($150): I have all three, and the BorisFX and Digital Anarchy product work very well, almost miraculously. They are useful on time lapses, exposure stepping due to auto ISO, banding from fluorescent lighting, and for slight pulsating light from whirling blades of a ceiling fan. I've tried the $25 Seed De-Flicker a few times and it doesn't seem to help much. Maybe further tuning would help, but it is not using the same method as the first two, ie analysis of groups of frames within a given window. It is probably using a simpler approach like Karsten mentioned above.
Outside of FCPX there is also a flicker-reduction tool in LRTimelapse (about $100): Ideally you should never make a mistake, always review your shots in the field and avoid causes of flicker. However this is not always possible, esp. With time lapse. The value of these tools can be compared to the value of the material that would otherwise be lost or unusable. In some cases you can write off the shot and use other material, in other cases re-shoot it at low cost.
However in many cases using these tools saves thousands of $, or salvages irreplaceable content.
Digital Anarchy Flicker Free
Has developed a plugin called. Working with FCP, Premiere Pro and After Effects (among others) it very effectively removes flicker from time lapses, slow motion and refresh rate phasing (LED lighting and monitor screens). Time lapse is a widely used filmmaking technique.
It was first made popular during the video DSLR movement and since then a multitude of accessories and software support to improve the workflow has been developed. One aspect of these is flicker reduction software, smoothing out exposure shifts over a long period of time. I’ve used a few selections that have been great at this process. Similar problems are present in other genres of filmmaking. As these become more popular, many are encountering new forms of flicker on a regular basis. Slow motion and LED lighting have become repeated offenders, as they become more accessible and cost effective.
However these are different forms of flicker to the kind we often find related with time lapse. LED and monitor screen flicker modulate and band. Slow motion can also, stemming from light sources and can be a lot more prominent than exposure shifts within time lapses. For these reasons, the same flicker reduction tools have not always been effective. Where these time lapse specific flicker reduction tools fall short, is where steps in. Made a tutorial on a DIY method for slow motion flicker removal. This is only effective with certain types of slow motion flicker, where the conflicting light source is strictly on/off (no modulating).

Opacity blending frames can also create a kind of motion blur, so the technique is not always effective. The software works by analyzing frames within your image, and how the luminance and brightness values relate with neighbouring frames. It then looks to smooth out these changes by adding light exposure alterations. The plugin by Digital Anarchy is quick and simple to use, working seamlessly with your parent NLE system.
Air jordan. It contains a few presets including time lapse, slow mo and a few different types of LED lights and monitor screens. It then has a few parameters including sensitivity, threshold, time radius and ability analyze channels independently/together. I strongly recommend checking out the instruction manual found for explanations of how each parameter affects your outcome. The test footage online is a little hard to determine due to the low quality output, so I put it to some test of my own.
Below is a quick example timeline of a few conflicting clips I’ve found in my own archives (some 4 years old!). Pay particular attention to the modulating flicker resolution of clip 2, this is really where this plugin shines as modulating flicker is hard to remove. It doesn’t remove all of it as you can see, but it does a pretty decent job for the most of it. In regards to the last clip, I thought I’d add three examples – original, preset applied and preset tweaked. This just gives you an idea of what it looks like in comparison to applying one of the untouched presets, and after you have adjusted the parameters to suit your clip. It’s clear that in some cases you have to tweak the settings to get it just right.
For reference, 90% of the other clips were just a preset. There was some flicker I wasn’t able to come close to removing in another clip (frame grab below), caused by my. However this modulation was more of a band than a flicker, and I anticipated it would be a little too much for the plugin as the luminance values are very similar throughout the whole clip. Digital Anarchy states that the larger the bands usually the more effective the plugin will be. There are quite a few plugins out there that can resolve similar results. However these are usually tied up in expensive software packages.
Is simply a nice cost effective third party plugin to a NLE system of your choice. Whilst it shouldn’t be relied on as a fundamental part to any workflow, it certainly does well at getting you out of some otherwise awkward situations.
