  • ffmpeg for archval and convertability

    26 juillet 2021, par Satya

    I've got a couple hundred gigs of *.dv files. I'd like to convert them to H.264 or something else or even leave them alone. The purpose is archival, with an eye to maximum convertability especially to DVD. The content is family videos.

    


    Would this be fine ?

    


    ffmpeg -i input.dv \
    -c:v libx264 -preset slower \
    -crf 17 \
    -pix_fmt yuv420p \
    output.mp4


    


    I went with the slower preset because encoding time isn't an issue and I'd like a smaller file size. crf 17 is for least-lossy while being widely playable. I read somewhere that yuv420p is needed for some Quicktime players.

    


    Should I throw in -c:a aac for AAC audio ? The audio is voice only, no need for music-hall quality.

    


    I looked at https://trac.ffmpeg.org/wiki/Encode/H.264 for previous research and that's where I got those settings, but it is silent on the audio settings.

  • Concat 2 H264 mov into mp4 using ffmpeg or other ?

    19 septembre 2013, par pixelwiz

    We recently bought a JVC GY-HM650U camcorder. One of the things it can do is record into a "web" format at the same time it records HD. However, the problem we've ran into is that it splits up the recording about every 30 minutes. I've contacted the manufacturer and they might fix the firmware in the future, but I need to do something about it now. So the camera produces an MOV file, but it's supposed to be a H.264 mp4 under the surface. I tried to follow the steps here : http://ffmpeg.org/trac/ffmpeg/wiki/How%20to%20concatenate%20%28join,%20merge%29%20media%20files but was not successful. I can either merge the two files into one mov, and if I try to play the MOV in JWPlayer for some reason I lose the audio. If I try to go into a .mp4 I get an error. I found some 3rd party software for joining video files without having to re-encode them if they are already encoded the same way, but none proved successful at producing a playable file with audio. Any suggestions ?
