  • How can I reencode a video to match another's codec exactly ?

    24 janvier 2020, par Stephen Schrauger

    When 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
       Stream #0:0[0x1011]: Video: h264 (High) (HDPR / 0x52504448), yuv420p(progressive), 1920x1080 [SAR 1:1 DAR 16:9], 59.94 fps, 59.94 tbr, 90k tbn, 119.88 tbc
       Stream #0:1[0x1100]: Audio: ac3 (AC-3 / 0x332D4341), 48000 Hz, stereo, fltp, 256 kb/s
       Stream #0:2[0x1200]: Subtitle: hdmv_pgs_subtitle ([144][0][0][0] / 0x0090), 1920x1080

    The phone (iPhone 5s) encoding is :

     Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'mov.MOV':

    I’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.
