ChainsawAsh said:One thing you will have to watch out for is the combined video and audio bitrate - I tried for months to combine an anamorphic GOUT I made (not cleaned up at all, just anamorphic) with the uncompressed mono WAV, and I kept getting errors until I finally realized that the maximum bitrate was too high. I don't think you'll run into this problem with 448 AC3, but it may still happen, depending on how high your video bitrate is.
the video bitrate is 6500 average.
