I am trying to add a simple color overlay to an existing video, following one of the examples at http://www.ffmpeg.org/ffmpeg-filters.html#Examples-55 (see the example Add a transparent color layer on top of the main video)
I am getting strange behavior with the following command:
ffmpeg.exe -i input.mov -filter_complex "color=c=red@.3:size=1024x768 [over]; /
[0][over] overlay" output.mkv
ffmpeg generates normal-looking output (below) then repeated logs of work on the same frame. This continues indefinitely. If I hit Ctrl-C, work resumes, ffmpeg completes the task and the output file is generated (with the overlay).
Is there something wrong with my color invocation?
