New Jerky playback Problem

[mikeb2168]

I have an xvid encoded avi file, when run through g-spot it says it's pal at 25 fps progressive and plays fine. After I run it through cce to produce an mpeg2 it plays back jerky ie/ it isn't smooth motion, it seems to stutter. I searched the forum but this exact problem doesn't seem to have been reported, as I have tried swapping the field order etc, but to no avail. Any help is much appreciated.

wich framerate has your resulting MPEG Video?
(NTSC or PAL?)

if your AVI has 25fps, then your MPEG has to be encoded with the same framerate (25fps)

Hi, yes the mpeg file is 25fps, I tried running it using dvd2svcd but it crashed cce! so maybe the avi isn't fully compliant.

I too have the same exact problem with an XVID conversion. I've used CCE many times and never had a problem like this before. The .avi file plays beautifully, but after converting to MPEG2, it comes out jerky/stuttery. I tried converting it with TEMPGEnc and it came out fine. Pity, the quality is not even close to what I could expect with CCE. I'm curious, is the XVID file you're converting a Quentin Tarantino film?

Are the settings ok for progressive source ?
In the video menu (2.5)
activate "add sequence end code"
Deactivate "upper field first" <-!!!!!!
activate "Progressive frames"
activate "Linear quantizer scale"
activate "zigzag scanning order"

?

Looks OK to me.

[yup]

how You frameserve to CCE use Avisynth or other? Many people use different decoder directShow (ffdshow or Nic)or windows registered encoder (Control Panel Multimedia). How type XviD? With B frames or not?
yup.

Hi, Thanks for all your replies I appreciate the help, but the same jerky playback has happened again with a ntsc xvid avi to mpeg file at 23.97 fps, plays great as an avi but once converted it's jerky as hell, using dvd2svcd to convert with avisynth as the frameserver and CCE to encode. Aaarrrrgh!!!:mad:

Well, did you run Pulldown afterwards?

Same problem here with Divx 3 low motion-videos. The avi plays with minimal jerkiness but become more pronounced when converted to DVD and played on a stand-alone player. I think it has to do with the decoder filter. I've tried Divx 5.1.1 and ffdshow, both gave same jerky results. Is Div 3.11 compatible with Windows XP and WMP 9.0? I installed it but it couldn't decode the Divx 3 video file. I always check with GSPOT to see which decoder is being used.

What is the framerate of the AVI?

[rs008f]

The frame rate is either 23.976 or 29.97. It seems the jerkiness is prevalent on all my conversion from Divx/Xvid to DVD. I tried TMPGEnc and it still give jerky movement during panning when played on a stand-alone player.

[RB]

I'm not a NTSC user so I'm not of much help, I'm afraid. Anyway, for the 23.976 FPS AVI, you definitely need to add 3:2 pulldown after encoding. Did you do this?

[rs008f]

yeah I did. The jerkiness is only visible during panning scenes and played on a standalone player.

That looks like wrong field order. In CCE Video Settings, try setting "Offset Line" to the opposite value (0 if currently 1, otherwise set to 0).
