Max bitrate set to 8,000, but authoring tool says 9,800?

[PlazzTT]

I've encoded a video in CCE (intended for DVD), and I have set the max bitrate to be 8,000. (The average is 4,700).

When I try to import this into Tsunami DVD Author, it says that the video bitrate is 9800kbps. (Combined with my 256K audio,it says that this exceeds the 9,848kbps limit.)

I thought it was a Tsunami problem, but under the Pin Info tab in the MPEG-2 video decoder I'm using with MPC, it also says:
VIDEOINFOHEADER:
rcSource: (0,0)-(720,576)
rcTarget: (0,0)-(0,0)
dwBitRate: 9800000
dwBitErrorRate: 0
AvgTimePerFrame: 400000

Is the problem here with my CCE settings, or with Tsunami and the MPEG-2 decoder I'm using?

Use search option in CCE thread.

Thanks, I should have known to search better.

Try to patch only the Bitrate with DVDPatcher (old, small and free).

Thanks, I used bitrate tool to find out what the real max bitrate was (it said 9402kbps even though I set CCE to have a max of 9000kbps).

Anyway I used DVDPatcher to patch the header from 9800000bps to 94020000bps.

Seems to keep Tsunami happy.


But then I found out that the original output from CCE was being detected as interlaced by DGIndex (PowerDVD was "de-interlacing" it too), even though the AVS input I used in CCE already had TDeint. I don't know if this is just because of a wrong header, or if CCE actually encoded it differently, thinking it was interlaced material.

Anyway I've decided to get rid of the deinterlacing in the AVS input, and let CCE encode it as interlaced (with "for DVD" off).

DGIndex detects the flags in the stream so you have encoded the video as interlaced.

For DVD, it's always recommended to keep interlaced material as it is anyway so you're on the right track :)
