OK to falsify values in Scenarist script?

[jriker1]

I have a DVD I am creating that has two videos with different audio bitrates. One is 448kbps and the other 384kbps. Because of this, Scenarist complains when it tries to multiplex to DVD. What I did was export the scenarist script, modify the 384000 to 448000 and opened that script in scenarist and then created the DVD. No longer complains. Is this a bad thing to do? Is there something that I will later see when I play this DVD (rewritable burning now) that will cause problems? Does it even really use this information for anything?

I know if I even try to go to the scenario editor, after importing the script, it will start the hard drive chugging away and eventually crash which concerns me. Because of this I avoid that tab in this case.

Thanks for your input.

assuming that scenarist is muxing it correctly (im sure it is.. ive done what youve done a few times unintentionally.) Its technically wrong but ive never had an issue. i would say if your player handles it then your ok. just be warned it is possible some other player may not like it.

I've never found anything that would indicate that the audio bitrate must be consistent for one audio track in a VTS. Bitrate is not one of the parameters specified in the ifo. However, bitrate does affect the multiplex itself, and should be consistent in each Scenarist "track" (aka segment or vob).
As for fiddling with scripts, my observation is that Scenarist treats .scp files as a database dump, and believes every value in it is correct. This can work for you, as in this case, or against you if you provide bad data. The usual result is a crash or hang.

If you want to use scenarist for this kind of dvds it's the only way to get around this ' problem' . There are other packages that allow such things. And also for example leave audio tracks 1-3 empty and fill 4 for example. I believe dvd studio pro (the successor to maestro so to speak) allows this. SCenarist is just less flexible in certain aspects unfortunately.

I altered the script and re-imported it. After converting to DVD played the entire DVD on my stand alone DVD player and did not find any audio or video issues so hopefully all is good. Thanks for all the input.

Why not re-encode one of the audio streams. If you try this with video( using restream to change the max bitrate flag) you'll get problems. The example I used was to encode video with a max bitrate of 15Mb/s and try and convince Scenartist that it was really <9.8Mb/s. It failed when it came to multiplexing as the bitrate would have at some points exceeded spec(evenv though in most parts it wouldn't). This may happen with audio.

I was trying not to reencode as I had one audio file that was 5.1 448kbps and didn't want to reduce such a good quality audio track and the other was 5.1 at 384kbps and didn't think there was value in upping it to 448kbps which would then reduce the video size due to upping the audio bitrate with no added value in sound.

The increase in file size will be quite small, although you're right about the quality.
