![]() This will split it into roughly 10-minute chunks, split at the relevant keyframes, and will output to the files camouth26401.mp4, camouth26402.mp4, etc. ffmpeg -i invid.mp4 -threads 3 \ -vcodec copy -f segment -segmenttime 10:00 \ camouth26402d.mp4. You can use it to perform all kinds of amazing manipulations on video (and audio) files, if only you can work out the. ![]() Is there a way to extract multiple parts in a single command? Like scans from 0:00:00 to 4:00:00, start extracting to 4:30:00, stop extracting and continue scanning to 6:00:00, and start extracting again.until the last part. Just use what is built into ffmpeg to do exactly this. So I wanted to simplify this process to save time. I tried using commands like following: ffmpeg -i input.mpeg -ss 4:00:00 -to 4:30:00 outpath1\d.pngįfmpeg -i input.mpeg -ss 6:00:00 -to 6:30:00 outpath2\d.pngīut it seems that each time it is executed, ffmpeg scans the file from the beginning, causing the process to be very slow.įor example, when I execute the above commands to extract the part of 4:00:00-4:30:00, ffmpeg will scan from 0:00:00 to 4:00:00, start extracting the image sequence, and stop at 4:30:00 and then I execute another command to extract the part of 6:00:00-6:30:00, and ffmpeg scans from 0:00:00 again to 6:00:00, and then start extracting. ss can be used in different ways, depending on how you want to cut the video. I have some huge MPEG files that is 24 hours long, and I need to extract a few parts (about 30 minutes each) of it into frame sequences (still images). To cut a specific part of a video, you use the seeking option -ss to get to a specific part that you want to cut.
