Technically we announced this at NAB, but this is the official release because there are now tutorials and a manual. i.e. info on how to actually use the plugin.
Anyways! Since its launch, Flicker Free has helped thousands of videographers and video editors fix problems with flicker caused by lights and cameras being out of sync, drone footage, time lapses and slow motion video. With the release of Flicker Free v3.0, Digital Anarchy is introducing a new algorithm that fixes an even wider range of problems. Capable of analyzing more of the video with better motion detection, Flicker Free is now able to fix issues previously not possible, particularly slower moving bands caused by LED lights.
In FF 2.0 you were limited to a Time Radius of 10. Which gave you a max range of 21 frames… 10 frames before the current frame, 10 frames forward, and the current frame. So about 2/3rds of a second, at 30fps.
In Flicker Free 3.0 the Time Radius limit has been increased to 19, so a total of 39 frames, 19 back, 19 forward, plus the current frames. About 1.333 seconds at 30fps.
Also, there is now a STEP parameter which has a limit of 5. This tells FF to skip to every nth frame. So with Step set to 5 and Time Radius set to 4, it’d look at Frame 1, 6, 11, 16, instead of the normal 1, 2, 3, 4. You’re still using 4 frames (max of 19) but they’re spread out. This means FF 3.0 (time radius = 19) can look at a maximum of 6.5 seconds to try and correct the flicker. (at 30fps)
To give you a better idea, here it is visually. 'Step = 1' is basically what FF 2.0 is doing.
