CCE "stutter" problems

[spon23]

Hello all. I've been reading and re-reading the forums and guides here and elsewhere, but can't seem to figure out what I'm doing wrong. I've got an xvid with a frame rate of 23.976. I'm using CCE w/ AviSynth to convert to to MPEG2. The resulting MPEG plays with a constant "stutter" and I can't figure out why. I've set the "Offset Line" in CCE to both 1 and 0 and both of them yeild the same results.

I AM able to successfully convert the same file with DVD Santa, but I would really like to be able to use CCE b/c the quality I get out of it is better.

Any suggestions?

Where are you seeing this stuttering? If its on the pc then it sounds like maybe a decoding problem unless you changed the framerate in avisynth somehow. If it is jerky on your hardware player then you probably forgot to set the 2:3 pulldown flag. This can be done in later versions of CCE or can be done afterwards using pulldown.exe.

23.976fps does not comply with the DVD standard and will playback very jerky on many hardware players. You have to add the pulldown flags to instruct the player to telecine it to the NTSC required framerate or 29.97fps.

As for the offset line, I can pretty much say with certainty that your source is progressive therefore you should set it to 0. Setting it to 1 won't really change anything but it will needlessly crop your first scan line.

Thanks for the reply. I should have specified that the stuttering is evident on my pc and also on my stand alone DVD player. I used pulldown.exe on the .m2v file after it was encoded in CCE. Then used both TMPGEnc DVD Author and also Ifoedit to author the DVD.

I don't know if stutter or jerky is even the correct way to describe it. It's not any better or any worse in motion scenes. It's like the video on plays every other frame. It "slips" from one from to the next. I've had the same problem periodically using TMPGEnc also. It's really driving me crazy b/c for the life of me I can't figure out what the problem is.

Post your AVS script here.

This could be a decoding problem. Try playing the AVS in media player and see if you get the same jerkyness. Of course if you are running alot of filters then you won't get real time playback, so you won't be able to tell. If this is the case then open the AVS in VirtualDub and try saving out a minute long section and then viewing it.

Some sort of interlace error, or artifacts of earliest interlacing?

It sounds like a typical old codec problem to me.

Install the latest version of FFDShow

and

Install the latest version of the 'full' XVID codec.


Pre-version 1 XVID codecs (example XVID version 0.91) will NOT play back later versions correctly (especially XVID version 1 RC's 1,2,3 & 4)........they 'stutter'... every few frames 'freeze' then pick up for a few frames then freeze again.

Thanks for the feedback guys. I'll post my Synth script when I get home tonight- maybe that will shead some light on the problem.

I'll make sure my codecs are updated, but I think they are. The original xvid files plays perfect in all my media players. I'll check, but I'm also pretty sure that I previewed the synth script and it looked to play ok also. As far as I can tell, it's only the actual resulting MPEG that plays that way.

I think it has to be something with the scrpt or the CCE settings b/c I can convert the exact same xvid using DVD Santa (no settings availalbe) with no problems....

ok, here is a copy of my avs script:

AVISource("H:\nameofthemovie.avi",false)
LanczosResize(720,460)
AddBorders(0,10,0,10 )
ConvertToYUY2()

I updated all of my codecs and that didn't seem to help at all.

I remember same problem was reported long, long time ago, and I also had it with CCE. It took me a while to find out it was the wrong DAR flag. At the time I was using CCE 2.50 SP and set DAR to 16:9, then I got this stuttering problem. After reset DAR to 4:3, everything was fine. I don't know if CCE has correct it in later versions. If nothing else works, check to see if it's because DAR flag.
