  • ffmpeg convert mov to mp4 without reduction of bit rate

    17 février 2021, par connor449

    I am trying to convert a mov video to mp4, but I don't want any compression to happen. I recorded it with Quicktime on a Mac and did so with maximum, uncompressed quality. When I run ffmpeg -i. I get :

    


        Stream #0:0(und): Video: prores (apcn / 0x6E637061), yuv422p10le(bt709), 1280x720, 72073 kb/s, 30.09 fps, 30 tbr, 30k tbn, 30k tbc (default)



    


    Note the kb/s is 72,073. I want to preserve this bit rate.

    


    I've tried a few different conversion commands, including :

    


    ffmpeg -i input.mov output.mp4


    


    and :

    


    ffmpeg -i input.mov -qscale 0 output.mp4



    


    Both work, but both result in a loss of bit rate. See info on the results of both

    


        Stream #0:0(und): Video: h264 (High 4:2:2) (avc1 / 0x31637661), yuv422p, 1280x720, 4569 kb/s, 30 fps, 30 tbr, 15360 tbn, 60 tbc (default)


    


    How do I convert to mp4 and still have 72,000 kb/s ? Is this possible ?

    The condition cannot happen anymore.

  • ffmpeg multiple overlays at different times

    14 octobre 2017, par TheOctagon

    I have written a bash script which cycles through various RTMP live streams and switches every thirty seconds.
    I have a PNG sequence which plays at the start of the video (blindRev-%d.png). A blind is pulled up, revealing the stream.

    28 seconds later, I would like it to come back down to cover the stream so that when the next stream is loaded, it retracts to reveal the next stream in sequence once again (blind-%d.png). I’ve tried using itsoffset to accomplish this. No audio is required.

    However, only the first PNG sequence is played, the second never seems to happen.

    The command I am using is :

    ffmpeg -i rtmp://localhost/live/$stream -i blind/blindRev-%d.png -itsoffset 28 -i blind/blind-%d.png -filter_complex overlay -an -f flv rtmp://localhost/live/All

    What am I doing incorrectly ?
    Many thanks.
