Max bitrate wrong in Rebuilder: v1.10.6 and CCE SP2

[Fishman0919]

I just tried a few movies with Rebuilder: v1.10.6 and CCE SP2 and noticed the max bitrate avg was a little low....around 4050k. I did 1 of the same movies with CCE Basic Version: 2.70.1.11 and the max bitrate avg was around 8500k.

I noticed that the OPV max was the same as CCE Basic

You have to be very careful in reviewing these things when they (CCE) make such huge ECL changes. You should go back and review some ECLs created by SP2 alone. The bitrate scale in SP2 isn't the same as SP... all the bitrates are 2.5x the "true" bitrate... I have no idea why -- only Custom Technology could tell you that, I just followed what I saw. Apparently the bitrate's "idx" is different than the "bitrate"???

Load the ECL and see what the encoder tells you is the bitrates... they'll match what you see in SP.

Another note in this light to all NTSC users:

When you see bitrates that you don't like... for example a MAX that looks too low to you -- give DVD-RB some credit and don't change it -- and if you do, change it at your own peril and don't complain when you get playback stutter. Remember that NTSC bitrate values can be 25% higher when they get converted back to 29.97 from 23.976 in the REBUILD phase. So if you decided you wanted to change it to 9000, for example -- you might get a result of 11250 which is way outside of specifications!

Just a warning.

Hmm... So it should have been set to 20062 rather than 10557... I'll look at it.

[jdobbs]

Yep, found it and fixed it. Sorry I doubted you, Fishman0919! I was too quick in my answer.

This also explains why all my SP2 encodes in testing had a tendency to undersize!

Good eye.

[jdobbs]

@Fishman0910

Here's (http://www.jdobbs.com/test/DVD-RB_v1.10.6b_test.zip) a test version. It should correct the maximum bitrate error in the beta SP2 code. Just replace REBUILDER.EXE with the one in the zip file.

Thanks jdobbs
