  1. I'm running the following ffmpeg invocations looking to get a target bitrate of 2853k:

    Code:
    ffmpeg -i infile -target ntsc-dvd -s 720x480 -b 2853k -pass 1 -aspect 16:9 -r 29.97 -vf yadif -y -mbd rd -trellis 2 -cmp 2 -subcmp 2 -an -threads 16 -f rawvideo -y /dev/null
    ffmpeg -i infile -target ntsc-dvd -s 720x480 -b 2853k -pass 2 -passlogfile ffmpeg2pass -aspect 16:9 -r 29.97 -vf yadif -y -mbd rd -trellis 2 -cmp 2 -subcmp 2 -acodec copy -threads 16 outfile
    But during pass 2, the bitrate reads in the low 3000k range. Any ideas?

    FFmpeg shows a overall bitrate of audio and video. At the first pass you set -an, at the second pass -acodec copy.

    To check out if this is right, you could do a test where you also enable audio at the first pass.
