femme fatale bitrate problem

[Ganglion5]

I was trying to author femme fatale with scenarist. For some reason, I kept getting the following message around the 33% mark during the main movie authoring:

Error Video or Audio Buffer underflow: (Dts: 618068182, SCR 618068248)
Error dvd_mux : DoMux Multiplexing Error
Error Terminated Multiplexing (2.scn-VTS__02_P01.16~9_1.mpv-t_t.vob).
Error Total bitrate is too HIGH. Please reduce the stream bitrate or the number of stream.
Error Multiplex is failed.
Info Multiplexing failed, Track<VTS__02_P01.16~9_1.mpv-t>

I'm not doing anything different this time than all the other time that I used scenarist. I use Do4U, CCE then scenarist. Any help as to what that error message means is greatly appreciated. Thanks

The errors means exactly what it says. Your total bitrate (video+all audio streams) is higher then allowed according to the dvd standards (=9800). I'm sure that if you do a search here on bitrate you'll find some answers.

But for example if you have one video stream and two audio streams one at 384 kb/s and one at 192 kb/s. You video should have a max bitrate of 9800-384-192=9224

The bitrate maximums:
total of all streams = 11.08 Mbps
all streams minus DSI packets = 10.08 Mbps
video = 9.8 Mbps
audio = 6.144 Mbps
subpicture = 3.36 Mbps

Thank you :p

I'm a newbie here, so please excuse my numerous questions. Is there any way I can make sure my video bitrate doesn't go above 9.8? I'm pretty sure when I encoded the video using CCE, I set the maximum at 8000kbs. I'm reencoding the video at max of 6.5kbs as we speak. Will that help? Also, if 2 of my 3 audios are dummy audios, will that count toward the total bitrate? Thank you again.

[influenza]

The dumies will count. Can you tell your lay-out (exact number and bitrates of you audio streams)?

[mpucoder]

A max of 8000 should have given you plenty of headroom for other streams. Is this NTSC? If so, and the source is 23.976 FILM, make sure that you did pulldown after CCE.

[Ganglion5]

The video was set at a max of 8000kbs,
Then I have an audio at 448 kbps
A dummy audio at 448kbps
2nd dummy audio at 192kbps
As for the subtitle, I don't even know how to check the bitrate for that.
I hope the info I'm providing is accurate.

[Ganglion5]

I'm pretty sure it's NTSC. It played on my standalone without a problem (my standalone is pretty picky).

[influenza]

Like MPUCODER said 8000 was a low enough bitrate for this, so this is probably not the problem then. So maybe you had to perform pulldown first, before importing your video.

Maybe you can check out trilights site (uberguuide) for more info.

Your problem may be that CCE (or pulldown.exe if you used it) has flagged the file with a 9800 maximum even though it is really 8000 like you specified... I've noticed it happens sometimes.
To fix this:
1) Use bitrate viewer to check actual max bitrate
2) Use ReStream to set the correct max bitrate flag

[Ganglion5]

I haven't tried the program yet. I'll give it a try today. Just so I know, do I have to find where in the file the max bitrate is reached, or do I just run the program and have the stream "deflagged"? Thanks.

[DIggedy]

When you use bitrate viewer it will scan the file and tell you in the information panel what the max bitrate reached in the file is. You then just use this exact number to reflag the stream using ReStream.
