  • Creating a transparent color mask that covers half of every frame in a video with opencv/moviepy/ffmpeg

    24 octobre 2019, par Nyktofob

    I’m doing a pose estimation in rats separated into two compartments of a cage. To make my tracking better I want to put a transparent color mask that covers half of every frame so that one of the rats will appear to the neural net as being of different color, thus making it easier for the net to differentiate those rats. My question is : Is there any easy way to do this using python (moviepy/opencv/ffmpeg) ?

    Bare in mind, I’m completely new to python, so I’d appreciate any recommendation of a tutorial or detailed answer.

    I tried using blender to do this, but failed miserably.

    I expect to be able to modify the video, so that there will be a rectangular transparent mask in some color that covers certain part of every frame (Let’s say video is 1920x1080 pixels, so from pixel 960 on x axis everything to the right is transparently green)
