Dropouts... in se7en R1

[gizzin]

Its been awhile since I had any problems with Rebuilder. Used CCE 2.7 basic, 2passes. Everything was left at default. Stripped the other audio tracks except the 5.1 audio. Maybe some new code introduced brought back the dropouts perhaps? Just a assumption thought I'd mention it. Good work. Oh yea I'm using v1.01

[HKT3020_1]

I planned on doing this sometime between today & tomorrow and for whatever reason didn't get to it last night. However I'm curious to know which Se7en DVD this is, the single disc or 2-disc Platinum Edition (the one I have) release? I'll let you know how my encode goes sometime tomorrow but first I gotta backup Cinderella. :D

Maby its the same that I experience

What exactly is happening?

I swear gizzin and eriksen76 you two are the only ones that have had this issue in months.... Im starting to think its a dvd player issue with you two. There is no other logical explaination...

[jptheripper]

is this a burnt dvd dropouts on standalone issue, or dropouts in windvd/powerdvd issue

I think its the first one.

Well, you might be right and you might be wrong. I can't say that I run every encode I do through in details, I think most people don't. So you might have overlooked a few bad encodes.

But I think you're right that its not a common problem. Still I think its in both Jdobbs and all users interest that the program supports all players.

At least the ones that can handle DVD+-R medias.

I agree to a point. I think it is impossible (or nearly so) to make a program such as this that support each and every player ever made. Hell, some studio mastered discs don't even work on some standalones, or stutter.

I've had sound dropouts on certain scenes with animes, but only with Panasonic
DMR-E60 recorder, other Panasonic players were OK.
The encoders were HC 015 and HC 016 trial2

If you saw audio dropouts with HC on earlier versions of DVD-RB (before v1.01) -- it may have been RB rather than HC. There was a fix put in (GOP sizing) that could be related to that.

[gizzin]

Um its a issue with my pioneer dv-343, This is only occurs on this standalone... Sorry for not describing it a little better but I figure after it happening some many times on so many movies It would just be common sense (A long time ago, like I said I thought this problem was fixed). All that happens is a few times throughout the movie the audio drops out and then goes back into sync a second later. This is the one disc version. Also with R1 of Summer Of Sam the same problem occurs but at only one part of the movie. Jdobbs wasnt able to re reproduce this one though, It must be a really pesky error that only happens rarely. And no this isnt a layer break and no this isnt a bad media problem. I use CCE and sometimes HC which is a very good encoder for free. TheSeeker you are right this only happens on certain standalones but it doesnt make the "standalone" the problem Its the output that is the problem. I actually took the liberity of doing this with scenarist and the problem doesn't happen. That fact is though DVD rebuilder is a whole lot easier to use and faster, and has generally the same flexibility. But you can't really compare the two. I'm not doing this for my own fun, I do it because its a error with playback that should be addressed. I can easily just use scenarist which I did and have a backup that doesnt drop out.

[jdobbs]

There has to be some set of circumstances -- rare as it might be -- that causes this. All I need to do is find it... Since I have Summer of Sam, maybe I'll run v1.01 against it and do some analysis.

Just finished watching the encoded DVD of Se7en and it works like a charm, no problems experienced whatsoever on my Sony NC-665P :)

I re did the same film with v1.01 and still get the sound dropout at the same place ( HC 016 -2 ).The bitrate is peaking at about 8 mbits when this is happening. Would increasing the bias from the default 20 for HC help?.
davidcw

[jdobbs]

You may try setting a lower maximum bitrate. I'd be interested to know if it has any effect.

[eriksen76]

I will try that with my "the mummy" also

I will try with a max of 7000 (CCE)

/Eriksen76

[davidcw]

I cut out the same 142 frames from the original movie and from the RB v1.01 movie that gave trouble, and the avg bitrate reported by BitRate Viewer was 6.59 mbps for the original and 8.15 mbps for the RB copy. Peak was 7.06 and
8.39 respectively. Will rebuild the whole movie again and set the HC maximum bitrate to 8 mb.
davidcw

BTW the reduction for the whole movie was 70%

[jptheripper]

are those bitrates with or without audio? if without audio, what are the bitrates of all audio streams

[davidcw]

I think they are without audio. There is only one audio stream and that is 2CH AC3 192 Kbps.
davidcw

[davidcw]

Reducing the max bitrate from 9 mb to 8 mb fixed the sound dropout problem with HC016. BTW this is not media specific as I burnt the discs with 3 different brands of media and and still got the problem with the same scene.

[eriksen76]

I encoded my "problematic" movie, "The Mummy" with a max bitrate of 7000 and the stutter was gone.

/Eriksen76

[jdobbs]

It sounds like it only happens on a couple of players -- and only when the average bitrate is fairly high (which as a corollary means you will actually hit closer to the top of the bitrate -- maybe even higher than the original disc). Since I use the audio tracks unmodified from the original, it's possible that may be the source of the problem... the video is larger rather than smaller than the original at that point in the backup.

I may be able to throw together an algorithm that will recognize that scenario and lower the maximum bitrate.

The avarage bitrate on the movie which stuttered when using the default max bitrate was as low as: apx 3200. So I guess thats not a fairly high bitrate.

Could this still have a connection to the problem?

To me it only seems that it's the max bitrate that makes the problem. But I guess it might still be able to hit the peak as on the original disc, or even higher even though the avg. bitrate is very low

Does this make sense Jdobbs?

/Eriksen76

[jdobbs]

If it were only the maximum bitrate, then DVD Maestro would see the same problem (and probably kick out an error)... I think it is related to the original audio timing being used intact with a higher peak. Not sure how or why yet, that's just a gut instinct.

[Fiebre]

This has happened to me every time I try and do The Life Aquatic. I get stuttering at the exact same points when DTS is turned on. This happens even when the movie is done on multiple computers and whether it is with CCE or HC. This is being played back on a pioneer dvr-225. It always occurs at about scene 16 and becomes progressively worse throughout the movie.
