I am authoring multi-angle DVDs for martial arts tests. Up to now, I've been doing only two angles, but have recently started authoring 3-angle dvds. Of course, I stepped down the bit rate in TMPGENC to something like VBR 2-pass, 2000k min, 4000k avg, 6000k max, highest quality. Unfortunately, the quality wasn't that good -- there was almost like a jerky ghost on the action. I gradually started bumping up the bitrate and seeing how high I could go. At this point, I'm already up to 2000 min, 7000 avg, and 8000 max and dvdmaestro is still letting me publish (and it's still playing on my apex). The quality is better, but still not terribly good once I put it in the standalone (looks fine on the computer).
Two questions: Why am I able to publish three angles as such a high bitrate? ANd why is the quality so poor (okay, you probably can't answer the second one, but it's bugging me because my other DVDs haven't looked this way)
thanks,

If your encodes are actually reaching as high as your allowed max bitrate setting, then apparantly DVD Maestro doesn't strictly follow all DVD limitations. This is a bad thing in my opinion. You will surely run into problems on any given dvd player.
For 2-5 angles your total max bitrate (audio + subs + video) is limited to 7.8Mbits. That applies to each angle separately, not in the aggregate. So assuming there was no audio or subs, each angle could be encoded at 7.8mbits. Seems you are currently exceeding this limit.
As for the quality, some scenes are difficult to encode. I can imagine that fast martial arts moves could prove problematic. But its really impossible to know what's wrong without knowing more about your encoding process. -
For your video quality problem instead of using VBR 2000 to 6000, you could try CBR (constant bitrate) with about 4000. You can experiment in that range from 5500 to 3500. This may make a difference, in any case, its worth a try. 8)

Thanks for the input. I have managed to get DVD Maestro to kick me out when trying to put two or more angles encoded at CQ 100%. But using the settings I specified before, the DVD burns fine and hs so far played great on multiple DVD players. Odd.
In any case, I've move the quality portion of the question to the Advanced Conversions forum.
Again, thanks for your input.
