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 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 do the above: ffmpeg -i in.mp4 -filter_complex "[0]trim=0:N[hold];[0][hold]concat[extended];[extended][0]overlay" out.mp4 Where N is the duration of the extension, in seconds.

Note that -accurate_seek is the default, and make sure you add -ss before the input video -i option. Note that it's better to use -filter:v -fps=fps= instead of -r as the latter may be inaccurate.
ffmpeg split avi into frames with known frame rate, ffmpeg_frames.sh. # Output a single frame from the video into an image file: ffmpeg -i input.mov -ss 00:00:14.435 -vframes 1 out.png. # Output one image every To force the frame rate of the input file (valid for raw formats only) to 1 fps and the frame rate of the output file to 24 fps: ffmpeg -r 1 -i input.m2v -r 24 output.avi For what it's worth: I use ffmpeg -y -i "video.mpg" -sameq "video.%04d.jpg" to split my video to pictures. The -sameq is to force the jpeg in a reasonable quality, the -y is to avoid allow overwrite questions.
