 |
|
I have MP4 videos that I want to generate PNG or whatever format from. I want to set the interval to an image perhaps every 2 seconds or some rate. Example: a 20 second video would have 10 images representing timepoint 0, 2 seconds, 4 seconds &etc.
I'm installing Mplayer and will try FFmpeg. My quick review of their documentation did not seem to suggest this kind of extraction was readily available.
Suggestions?

| From it seems that you may use '-vo png' to output png images from frames combined with '-sstep 2' (if I understood correctly, I'm not able to test it right now). .. |
