How can I reencode a video to match another's codec exactly ?
24 janvier 2020, par Stephen SchraugerWhen I’m on vacation, I usually use our camcorder to record videos. Since they’re all the same format, I can use ffmpeg to concat them into one large, smooth video without re-encoding.
However, sometimes I will use a phone or other camera to record a video (if the camcorder ran out of space/battery or was left at a hotel).
I’d like to determine the codec, framerate, etc used by my camcorder and use those parameters to convert the phone vidoes into the same format. That way, I will be able to concatonate all the videos without re-encoding the camcorder videos.
Using ffprobe, I found my camcorder has this encoding :
Input #0, mpegts, from 'camcorderfile.MTS':
Duration: 00:00:09.54, start: 1.936367, bitrate: 24761 kb/s
Program 1

handler_name : Core Media Data HandlerI’m presuming that ffmpeg will automatically take any acceptable video format, and that I only need to figure out the output settings. I think I need to use
-s 1920x1080
and-pix_fmt yuv420p
for the output, but what other flags do I need in order to make the phone video into the same encoding as the camcorder video ?Can I get some pointers as to how I can translate the ffprobe output into the flags I need to give to ffmpeg ?
Edit : Added the entire Input #0 for both media files.
