It probably changed when Upper Field First source footage became more the norm. Lower Field First is pretty much only used for DV, but more and more people are using HDV and AVCHD as source material and in those cases both the project and the encoding settings would be Upper Field First.

while we're on the subject of main concept - is there any advantage, and will vegas recognize the more advanced codec offered directly by main concept, eg. mpg2 and h.246/avc for example?

Unlikely, SCS licences the SDK (software developers kit) from Main Concept and tweaks and compiles it to their own needs.

thanks jc.

PAL Land
Timeline correctly set to UFF (source HDV from tape) .m2t. files.
Is it really necessary to create a custom template with UFF set. when rendering for DVDA widescreen video stream?

The comparable VP10 video stream is LFF by default. Not convinced there is a change between VP10->11.

Geoff, don't quite understand what you mean.

In Vegas 11, the default for NTSC Mpegs template is now UFF. In all previous versions it was LFF.

Dave T2

The default for PAL Mpeg templates is still LFF in VPro 11.

From VP 11 Release notes:
Notable fixes/changes in version 11.0 (Build 424/425)
From VP11 Help (still same as in 10 Help)
Upper field first

Seems to be in line with what everybody's saying above.

It is interesting that if you create a new project with NTSC DV it defaults to LFF as it should. When you then render to DVDA, why can't it default to the same setting as the project (LFF) if both UFF and LFF are acceptable?

@DaveT2

Typo Should have read 'Is it really necessary to create a custom template with UFF set. when rendering for DVDA widescreen video stream?'

I have always rendered to DVD widescreen video stream using the default template and assumed it to be correct. Noting Kimberley's post I checked the render settings for PAL and noted they were LFF.
VP10 is exactly the same.

Have just dropped some 60i m2t clips on a matched timeline and selected to render mainconcept DVD Arc** NTSC widescreen video stream and the default is UFF as stated by Kimberley, whilst VP10 gives LFF as default.

Why the change for NTSC and what is the correct setting for PAL?


Geoff

I don't know why they changed the default.

Technically a DVD can be either UFF or LFF. Generally, it is best to match the field order with your source material. Since DV-AVIs have always been LFF first, then normally you would make your DVD LFF. When capturing from a 720 x 486 source, most of the time your video is UFF, so your DVD would be UFF.

If you are converting from HD, the it really doesn't matter. the HD material is being completely redrawn and so UFF or LFF is your choice. Apparently SCS has decided since HD is normally UFF and a lot of people are downconverting to DVD, then to save confusion, they have defaulted the MPEG DVD Standard Definition to UFF.
