Digital Anarchy gop flicker removal

'Group of Pictures' compression fix By Ko Maruyama
Jim Tierney from Digital Anarchy discusses how to fix certain artifacts that arise from compressing video.  The tutorial also allows users to download the drone footage to see the correction that his plugin provides.

GOP stands for 'Group of Pictures' and is a common compression method. It groups multiple frames together to help get better compression rates. Typically this is 7 or 15 frames. In the case of the DJI Phantom Professional drone, it uses a 7 frame GOP. This causes a shift in pixels every 8 frames. In some video footage this is very noticeable as it's rhythmic pattern and creates a shimmering type of effect. The Flicker Free plugin can be used to minimize this, giving you a more professional looking video.

In this tutorial Jim will show how to reduce the video flickering caused by GOP compression artifacts, a common problem with video footage shot with drones. (DJI Phantom Pro drone in this case) This tutorial is done After Effects but the concept should apply to any host app: Premiere Pro, Final Cut Pro, Avid, Resolve, etc.

Several Digital Anarchy plugins work across multiple host applications - find out which one is right for you by going to their website: http://digitalanarchy.com/
