TMPGenc Problems.

[AzErTy]

Hiya,


I have been converting DVX / Xvid to VCD / SVCd for a while now.

Up until recently I havent been experiancing any problems what so ever, but with the last 10 - 15 conversions I have done the MPEG 1/2 encoded file seems to jump slightly.

Sound is in perfect sync, under any other conditions I would saw the CDR's I am using are crap, but I have tryed a load of CDr's both great quality ones and cheapo ones, and I get the same problem with any brand.


I have checked the source files on numerious occasions, and none of the source files have anything wrong with them in any way.

the only changes i have made to the TMGenc default settings is to bump up the "Directshow Multimedia File Reader" as i read here, because i was getting pinking with some encodes.



Im wondering if this is a problem with the newer builds of Tmgenc, as I never had it happen with older versions.

We're going to need a bit more information to provide any real help, mostly the framerate of the source AVI's (check with VirtualDub File->File Information) as this is the most common cause of very slight jumpiness. Are they jumpy on a PC or only a standalone player?

Will check the fram rate now of one


And they are jumpy both if i play the VCD Mpg in any media player on the PC and on a standalone DVD player.

Bump


can anybody help ???

strangely enough I've had the same prob after resetting priorities on directshow. I know it's a pain but you could change the framerate in virtual dub first to your desired framerate before encoding. Then TMPG wont have to and it wont jump. However you'll have to compress the sound by the same ratio to get syncing. wot framerate u converting to?

It sounds like your DVD player doesn't like 23.976fps VCD's Either.

Usually i just leave it on PAL SVCD or VCD, so 25FPS.

I encode a hell of a lot of stuff, and never had a problem until recently with this.

Im 99% sure I have encoded stuff with the same frame rate this movie has, and without getting out a load of blanks i cant be 100% sure, but i know that things are in Dvx / Xvid / SVCD and it dosetn matter what re-encode recently its all jumpy.

Again I cant be 100% but I have had this DVD player over 2 years, and It has played everything perfectly that i throw at it, itsonly been the past 3 months that I have been getting problems

Now I don't know what went on with my PC recently but after shifting priorities with directshow to sort purple shit I got all the stuttering and I couldnt sort it. Went for complete OS system format (had other probs as well), reinstalled everything, still got it. Now doing framerate conversion with virtualdub (ticking the 3:2 pulldown doesn't work in tmpg as others suggested, movie looks crap then). It works perfectly but doing this conversion is just more time that I didn't need to do before..... mail me at nathan9909@hotmail.com if u sort it. send me your e-mail, if I suss it first I'll get back to u.........

There's your problem, the skipping is due (as you have probably ascertained) to the framerate conversion.

I encode a hell of a lot of stuff, and never had a problem until recently with this.

I'm not trying to be disrespectful but just because you have done something a lot of times before doesn't mean you have ever done it correctly.

It was always there, you just never noticed it before - because of low quality and/or low motion source - OR your source video has previously always been 25fps to begin with. I never noticed the stuttering either until I came to convert some video clips from a good quality NTSC DVD.

Im 99% sure I have encoded stuff with the same frame rate this movie has, and without getting out a load of blanks i cant be 100% sure, but i know that things are in Dvx / Xvid / SVCD and it dosetn matter what re-encode recently its all jumpy.

I'm not trying to be clever here but it's because you've never noticed it, as explained above. From now on lets avoid pointless explanations and concentrate on the task at hand.

For the video in the screenshot you have supplied there are basically three methods for getting reasonable quality while avoiding jumpiness. The first is to use the method discussed here:

http://www.vcdhelp.com/forum/userguides/78178.php

The second way is to try something like Adobe Premiere or AVIsynth which can use a different trick (frameblending) and has the advantage of not changing the movies running time.

The third and easiest method is to simply encode this file to an NTSC VCD and see if it plays correctly in your DVD player (most PAL players do).

As a rule of thumb you want to avoid Framerate conversion at all costs because there is no perfect method, anybody that tells you otherwise is fooling themselves. Think about it like this, with an NTSC video source how many frames make up one second of video? 23.976 you say. But this makes no sense as you can't have 0.976 of a frame because frames are discrete (you have a frame or you don't) time is not (you can have 0.041708375041708375041708375041708 of a second which is the duration of a single frame in NTSC).

Does all that make sense?

hi there

in the latest version of TMPenc i have the same problem w/jumping vcd/svcd

try to install an older version of TMPGenc like 2.57

the problem is for sure of TMPGenc, try and you will see

2man

note - don´t forget to try kwag template (120 min in 1 cd 80min), adjust quality to 100%
