  • Bad quality output with FFmpeg, bitrate specified [closed]

    28 septembre 2012, par Darkman2412

    I have a static background image where I add 2 videos on top of it using FFmpeg CLI. The output file (test.avi in this case), is very bad quality.

    ffmpeg -loop 1 -i outro.png
    
      -vf "movie='intro.mov' [last], [last]scale=512:288[scaled1], [in][scaled1] overlay=290:396 [tmp];
    
           movie='intro2.mov' [featured], [featured]scale=512:288[scaled2], [tmp][scaled2] overlay=1118:396 [out]" -b 512k -t 10 -r 30 -y test.avi

    The first image is the first frame of test.avi.
    The second one is what it should be.

    image 1

    image 2

    Edit : my question is why it's such bad quality.

    Edit2 : Console output :
