Field order for DVD files

bearded wrote on 2/19/2002, 10:34 AM

I am encoding some analoge files captured from an MJPEG capture card (G400-TV). The field order seems to alternate between upper and lower for individual clips (quality).

Now when I do the MPEG2 encoding I have to choose the field order acording to the original source.

Therefore, the final DVD will have a mixture of upper and lower field order MPEG files.

Can a DVD cope with different field orders on the same disc ?

Alternatively if I render them all as no field (progressive) what will it play back like on a TV (i.e. interlaced) ? Will the DVD add interlacing ?

I am in PAL land if this makes any difference and using the VF patched MPEG2 plugin with VV3

If the individual source clips are interpreted correctly (meaning, lower field first clips are recognized as lower field and vice-versa), then that is all you need to worry about. Render to the stock DVD PAL template and Vegas will send the encoder the "right" info.

Thanks for the reply

What I did not explain is that in any one DVD movie that I will be using scene's from each type (upper or lower field) of source clip.

When I tried rendering either upper or lower field first, parts of the movie appeared to flicker depending on whether they where upper or lower field first.

On that basis I think my only option is to go for no field (progressive).

I believe this happend when the capture card changed to a subsequent file when it hit the 2 GB boundry.

Am I correct in assuming that a stand alone DVD player will re-interlace a progressive MPEG movie
