Repeat last frame in video using ffmpeg, So, the key is to overlay a truncated version of the main video over the full-length stream, thus "extending" the last frame. There's a different and simpler way to With a build of ffmpeg newer than 2nd Nov 2018, you can use the below command : ffmpeg -i in.mp4 -vf tpad=stop_mode=clone:stop_duration=2 out.mp4 Audio is ignored. For older versions, see below. The overlay filter, by default, repeats the last frame of the overlay input over the base input if the former has ended but the latter hasn't.
Freeze last frame of a video with ffmpeg, Thanks a lot. Just to post the solution (my video is without sound): # ffmpeg -f lavfi \ -i nullsrc=s=3840x2160:d=10:r=30 \ -i input_video.mp4 I believe the answer to your question is "yes". I'm not super familiar with FFMPEG, but the easiest way I can see to accomplish your goal is to first extract the last frame to an image, make a video of a few seconds and then run an encode that concatenates the main video and your newly created video in one pass.
