Tmpgenc DVD Author and 544x480 resolution?
 

I can't seem to get my mpeg-2 files encoded at this non-standard resolution to work with TMPGenc DVD Author. Has anybody else? I encode at 4:3 with CCE, and have no problems using DVD-Lab and DVDAuthorGUI. I just wanted to give Tmpgenc a try is because dvdauthorgui just seems too simple, and I discovered a problem with DVD-Lab where it makes pulldown files appear jerky (the other two programs have no problem with pulldown material).

Tmgenc doesn't accept ANY non standard res.
Even if sometimes you can load the source, you will have an error when you start the job.

BTW DVD-Lab I never noticed any problem with pulldown. I do all my NTSC jobs with it.

re: Jerkly playback with DVD-Lab:

What do you use for your encodes, CCE or Tmpgenc? I actually have yet to see if Tmpgenc encodes play smoothly, but I use CCE-SP Trial mainly for its far superior encoding speed. I was told it might be a field order issue, but my material is progressive not interlaced so I'm told field order won't make a difference. In any case, I have tried both offset=0 and offset=1 in CCE (one means top field first, the other bottom, but I consantly get them mixed up) with no difference. It happens at both DVD compliant and non-compliant resolutions (e.g. 720x480 and 544x480). It happens on both AVI source and DVD. And I either use Kwag's optimal script for DVD sources or your script for AVI sources.

The jerkiness is only evident on standalone DVD players, not on the computer. Oh and it might depend on the type of dvd player, my panasonic seems to emphasize them more than my sony, but I can't be certain of that -- it may just be the panasonic is connected to a 53" TV so any jerkiness is emphasized more. I know other people in this forum have mentioned this problem.... but it definately does not seem like a majority.

Me too except... when I have a pulldown to apply. In this case I use tmpgenc.

I understand that you try to do the pulldown into CCE ? Don't don that. Encode normally in 23.976 then apply pulldown.exe on the result.

I personnaly don't do that for obvious reason but that is normally the things to do.

As you can see, pulldown problem isn't due to DVD-Lab.

For sure. Remember that this operation is a "3:2 pulldown during play". That means that the pulldown is actually done BY THE PLAYER !

I always encode at 23.976 and either let DVD-Lab due the pulldown or I use pulldown.exe. Either way leads to the same problem when authored in DL. I suspect there are problems with the DL muxer in handling pulldown material... The jerkiness seen is NOT major, it is actually very minor and only distinguishable if you have the right eye for detail. I notice it during periods of medium to fast motion, like camera pans, or if an object moves from one side of the screen to the other such as a person or a car. It is just a slight jerk, like a single frame is missed, there is no pausing of the video and the sound doesn't go out. It is definately not the extreme jerkiness you see if you did a 25 --> 23.976 fps conversion, or something else where you have consistant dropped frames.

I'm just hoping someone out there might see this. Otherwise maybe I'll post a short 5 second clip where the jerkiness is consistently seen if authored by DL.

I think you didn't write this line for me ;-)

Note: do a test (sample) with tmpgenc just to sse if the problem can be related to VBV buffer size used by CCE.

You can patch the resolution to DVD-compliant and TMPGEnc DVD Author exapt it:

After the authoring you have to re-patch your file(s)!!!

Interesting... so you're saying I can use DVD Patcher to patch my 544x480 resolution to 704/740x480? But what do you mean by repatching after authoring? Do you mean patching the VOB files before burning? Bit confused there

Yes you understand me right. You load again the Video, now VOB, and re-patch it to the source resolution. So you haven't any problems with aspect ratio and the picture in gerneral. :wink:

okay, finally just finished doing this. no difference with tmpgenc vs cce, so it's not the encoder problem. The cce clip was encoded at 23.976, and when loaded into DVD-Lab it created a pulldown file for me. The tmpgenc clip was also encoded at 23.976 by tmpgenc has an option to encode with 3:2 pulldown (I'm surprised that CCE doesn't have a similar option, it has 3:2 pulldown DETECTION but the effect is not the same) so the resulting m2v loaded into DVD-Lab without any modifications needed. Both clips showed jerkiness on my standalone. Then I tried the same files but authored using DVDAuthorGUI and no jerkiness. Ditto with Tmpgenc DVD Author after trying the DVD Patcher trick.

Soooo.... it's a dvd-lab muxer problem! This particular encode was at non-standard 544x480 of an AVI, but I've had the same problem with 720x480 encodes from DVD where muxing with a different authoring program solved the issue.

I posted a message on the dvd-lab forum and am awaiting replies...

EM, i don't knew dvdpatcher 8O
means that i can put all my kvcds (audio 48k) in dvds using dvdpatcher :?:
simple like that ?

You don't need dvdpatcher for that : dvd-lab accept any KVCD resolution (352 / 480 / 544 / 704 / 720). But they MUST be in MPEG2.
I don't think your KVCD are MPEG2, are they ?

Like Phil said, but it's very good for another authoring tools like TMPGEnc DVD Author. Test it. It's very easy and you patch a KVCD in just seconds or less. :wink:

@ Phil & EM :

you're right Phil, my kvcds(352x240) are mpeg1 but i have some ksvcds(480x480) and kcdvs(352x480) mpeg2 audio 48k! :wink:

that hint to using dvdpatcher for TMPGEnc DVD Author is great EM! :wink:

thank you boys!

But think. Aber authoring with TMPGEnc you have to re-patch your KVCDs to determine problems. :wink:

EM,
what means "aber" ? :? :oops: my dictionary don't have that word!?!? :lol:

Surely the german word for "after" :-)

thanks super, now i understood!
:wink:

What the hell. Have i wrote "Aber"?! :oops:

No it isn't the word for after but I mean this.

The english word for ABER = BUT

Little german lesson. :wink:
