JERKEY CONVERTION and PLAYBACK

[Sosua]

Need help. I have done all kinds of avi to vcd or svcd. Never had any problem with sinc like lots of people do. I have done Xvid, Divx, Ac3, all kinds. Most of the time picture is perfect and sound also but my biggest problem is all my movies, or most of all all play a bit jerkey. Not that is a serious problem but it bugs me when it does that.

When the camera moves from right to left or left to right or when there is fast motion in the movie. For shure it is something that i do wrong because when i have a movie that is allready converted it plays just fine.

I, for shure, must be doing something wrong. Anybody can help me with this? Maybe somebody had this problem in the past and know how to resolve this mather.

Sounds like your bitrate is too low. Combine this with conversion from XviD/DivX and you have and under-bitrate encode of an under-bitrate video. Or Artifacts of artifacts. You can partially alleviate the problem with higher bitrates (SVCD). Working from higher quality encodes also helps. You can totally alleviate the problem by working from DVD sources.

Hmmm...sounds identical to the problem I used to have. I got jerkiness when encoding 23.976fps movies...I completely eliminated this problem by converting my source movies to 25fps (and time stretching audio to match) before encoding....at 25fps all my movies play silky smooth.

Big thanks for your reply guys. I have to say that my problem also comes out of 23.976 conversion. I usualy convert to SVCD, NTSC. My player will also play 25 witch is, i think, PAL. Can you be more specific on how to change from 23.976 to 25, i'm kind of new to this and never did that before. Should i, also keep converting to SVCD??

If your player can play 25fps (PAL) then its deffo worth trying my method of converting to PAL...and yes, keep making SVCDs.

I've already shown my method in another post...so I'll link to it to save me writing it all out again!...you'll find it about 10 or 11 posts down in this thread:
