​I am not sure I'm getting the whole picture of what you're doing, but if
you have a lot of blurring to do on each frames, maybe a script that output
each video frames into another tool doing the blur, which in turns output
into a second ffmpeg process for transcoding could avoid you a cascade of
overlays.
