I am writing to ask advice about how to augment my ffmpeg command line. I
am working through my iMac's Terminal.
The task I am trying to perform is to convert a whole directory of .mp4
files (all with unique filenames) to .png images whose labels correspond to
their original .mp4 files.
The line I've run is:
*for i in *.mp4; *
*do ffmpeg -1 "$i" image%03d.png; *
This command line batch converts all .mp4 files to continuous .png files.
That is, when moving from video 1 to video 2, the labeling does not start
all over to indicate a break between video files. I would like to insert
label breaks so that I can track which images correspond to which video and
know exactly how many frames exist per video by conveniently having them
labeled starting from 0 or 1 each time.
However, I don't know how to do this as I've searched online for a few days
and I think it's time for suggestions.
An example list of filenames:
and I want each to have a list of corresponding .pngs, i.e.:
One last note:
The reason I want to batch process is because there are at least 64 video
files in the directory total.
