Comment (by Tjoppen):
208542 is not a legal frame size for NTSC in D-10. See table 1 in S356m.
In other words, your encoding parameters are wrong, or FFmpeg's rate
control needs tweaking, or needs to complain that it can't fulfill exactly
50 Mbps for NTSC. However, 3d38e45eb85c7a2420cb48a9cd45625c28644b2e is
also wrong because S356m does not require the MPEG-2 stream to be CBR,
only that it is no more than 50 Mbps. A fix would be something like this:
Either revert or hide what 3d38e45eb85c7a2420cb48a9cd45625c28644b2e does
behind a sony vegas pro 11 specific AVOption.
After that, implement the actual constraints specific in S356m.
Optionally, have the rate control system refuse impossible parameter
combinations.
