Pull the video into some editing software and drop in a few replacement 
frames when needed. You could do this with ffmpeg, but it's probably going 
to be simpler in the long run with with purpose-built editing software* 
(FOSS editors often use ffmpeg libraries inside, I know shotcut does).

*openShot, Kdenlive, VidCutter, Shotcut, etc

(You might be able to build a house with just a Swiss Army knife, but it'll 
be easier if you also have a hammer.)
