  • Encoding a readable movie by QuickTime using FFMPEG

    29 juillet 2018, par itamarb

    I’m trying to encode an image sequence using the following command :

    ffmpeg.exe -i %d.png -f mp4 -vcodec h264 test.mp4

    However, QuickTime failed to open this file or sometimes play a black movie, while this movie plays great in VLC player. Any suggestions how to make it play well in QuickTime ?

    Here is the output :

    ffmpeg.exe -i %d.png -f mp4 -vcodec libx264 13.mp4
