TMPGEnc,avi converted to mpeg is jerky

[darkstate]

The AVI iv'e converted is NTSC and iv'e encoded it in NTSC,this is the 1st time this has happened to me,but my friend is having the same problem with some of his films as well,iv'e been using this for 6months or so without a single hitch that i haven't been able to solve myself,but this 1 is baffling me.
Iv'e tried using the avi (NTSC)then encoding into PAL but that doesn't work,i'm using MOTION PRECISION SEARCH(high qualitylow)VIDEO ARRANGE METHOD:full screen (keep aspect ratio)Video resolution =720x480.
If you want a more detailed report please don't hesitate to ask.
The program works fine on other avi's ntsc or pal,the avi is fine no jerkiness but converting it,it just doesn't come out a quality film,iv'e checked the frame rate is correct in vobsub of the avi,just in case it said it was 1 thing when it was another.
anyway hope you can help
many thanks for your time

The problem could be interlace video signal. During the tmpgenc encoding, the user has the options to select filed order A or B. Normally, the tmpgenc suggests correct field order by scanning the first few video frames.

The best way is decoding a short segment with different field orders (A or B) and comparing both output movies.

Good luck.

Field order is a real bitch. You'd think that by now someone would have come up with a reliable routine to pick it... but no.

I'll bet that's it, too.

AVI is NOT DVD. Please TRY post in correct forum. moving you.

Determining the correct field-order is really simple using TMPGEnc. Check my post here for how to do it.

If the avi is divx/xvid then it is not interlaced, moreover if the framerate is 23.976 then 100% progressive (that means non-interlaced). The field order have an importance only in interlaced video. Therefore the cause of jerkiness has other origin, not the field order.
