Still getting stutter

[jdobbs]

I'm still guessing it's an audio/video interleaving problem. I need to get up off my ass and fix it. I've been inundated with the paying job for the past couple of weeks and its putting a real limitation on my rebuilder coding.

jdobbs, you are right! I tried bitrate viewer with prince of egypt ntsc and in one vob (which I didn't wait to go all the way) would reach 11196 max.

Sorry for trying to push my wrong point of view :o
But hey, we're only human :)

I brought this up about month ago, and the problem still persists, so I'm bringing this up again. It's not entirely clear whether this is a problem with DVD-RB or QuEnc (or both) if this is definitely only a QuEnc issue, I'll bring it over there. Anyway, if you encode progressive film source (23.976 fps) with quenc, the playback will be very jerky on some standalones and Media Player Classic. This does not occur with with 23.976 interlaced content. This appears to have something to do with the prog_seq flag. If you set the prog_seq flag to interlaced before rebuild, the result comes out fine (and if you set the flag to progressive on a cce encode, you get the same jerkiness after rebuild). This may be a case of QuEnc just messing up the flags but shouldn't RB set these flags (like it does for the prog_frame flags), rather than just passing them from the encoded files?

Edit: There's a thread with some more discussion here (http://forum.doom9.org/showthread.php?s=&threadid=75923).

I haven't been following this thread very closely, but jdobbs informs me that the video/audio stuttering have been resolved as of v0.52 (aside from the QueEnc issue), but a problem with audio dropouts still remains. So, I'm going to close the original bug listing in the known issues thread and start a new one on audio dropouts.

Of course with burn errors, incompatible media, ect audio/video stuttering is an ever present error in DVD backup. So I fully expect to see more reports of this.

Reading the changelog for the latest release (v53a) I do not see any reference to the audio drop issue so I am ssuming this is still being worked on? Happy to try the latest version with my problem title's if there have been changes made which might fix this issue.

Jdobbs, could you please comment on the QuEnc issue mentioned a few posts up? I think that's the last real issue preventing QuEnc from being really usable (except the ratecontrol, maybe we could add a QuEnc maxbitrate option?).

I see v.054 is out but no mention of a fix for audio stutter which is rather dissapointing. I am getting this problem in most of my attempts with Rebuilder and reading the posts others are too. What is the priority for fixing this problem as I believe it to be quite a serious flaw in what could be the best backup app available!

i get this problem as well when encoding an MPEG 2 from a lossless avi.

i mean, when i do it from movies, even blu ray sources downconverting them to DVd res into a lossless avi, and then taking that into a CBR (oviously just below 9800KBS) MPEG 2 file, it works fine, but when i do it from a DVd recorded show and do post processing into a lossless avi and then back into CBR MPEG 2, it stutters.

for this, i did experiments, and when i compile it in DVDLAB Pro without audio, it works nicely, but when i add the audio track afterwards, just under a minute it all goes messy.

dont start blaming the CBR encoding, cause i know that has nothing to do with it, i dont understand why it is doing this.

does anyone know?

[jdobbs]

I guess I don't know how that is related to DVD-RB? Did you mean to post in an different forum?

[Undead Sega]

well it was to dow ith the video stuttering that i am STILL getting, and i saw this due to the keywords of DVDLab Pro.
