pal to ntsc
I am doing a Vegas 8 conversion from pal to ntsc which will eventuate as an Architect project with three programs on the disk in pal [one disk] and ntsc [separate disk].
I am unclear on a few of the conversion stages. Can you advise me please –
The original is pal dv – in Properties, as normal, it is set to Lower Field First.For the conversion to ntsc, Vegas 8 help file tells me to create a new project, then import the veg file. Done. But when setting the ntsc properties defaults, I notice it still stays as Lower Field First…I thought all ntsc was created Upper Field First!!!
I also notice there are two forms of ntsc projects associated to my needs – ntsc dv [720 x 480] and ntsc Standard [720 x 486]. In both instances Lower Field First comes up as the part of the default “package”. Is that right or do I need to change that to Upper Field First. And which on to use – dv or Standard?
Once I know that info, the help file tells me to render out to avi file. These three programs need to be rendered [at some stage] to dvd ntsc, so why should I go through the avi stage instead of directly to mpeg2? Si there some sort of quality loss by jumping straight into mpeg2?
Before burning I will put them through Architect 5 and I see there is another render template called dvd Architect ntsc Video Stream – why use that instead of good ‘ol dvd ntsc? And if I did use it, what is the procedure to render the audio and how to sync them in Architect?
thx in advance

Nope. NTSC DV is also lower field first.

Yes the defaults are correct for DV (lower field first). I would use 720×480 as the resolution.

I agree, go directly to MPEG2. No need to render to AVI first unless you were rendering for multiple formats and then it’s quicker to have a single file to make all of the other renders from.

Yes use the DVD Architect video stream template and render the audio as Dolby Digital AC-3. Make the filenames the same (just the .mpg and .ac3 extensions will be different) and DVD Architect will know that the video and audio go together.
Question for you: How are you planning to deal with the fact that PAL has much greater vertical resolution (576 vs 480)? You might want to crop the PAL veg file when it is a nested project to fit 480.

Thx a lot John, very helpfull.
Re the vertical cropping, I hadn’t even considered that. So the quick answer is I’ll take your advice and crop..but I dont know what a nested project is. Please tell me. Im still using a cafe for the email so bear with me, there is a lag between me going home, then getting back here to reply.
Thx

Geoff, a nested project is when you start a new Vegas project and import (rather than open) an existing veg file.
Add it to the timeline and edit as normal.
It’ll build a special file for this purpose so be patient while it’s created.
Be advised that, no matter how many audio & video tracks the original file had, it’ll be reduced to 1 video track and a stereo audio track.
If you realize that you need to make a change to it, right-click it and select Edit in Vegas (*.veg).
A new instance of Vegas will open up with the original file intact.
Make your changes, save it and close it.
Your existing project will be updated immediately with the changes you just made. -
Yea, if you’ve ever used After Effects, think of nested projects in Vegas like nested Compositions in AE. They serve the same purpose and are extremely power for compositing.

Wow, that’s an impressive and powerful tool. Can you point me toward tutes on it rather than waste your time telling me. Thx to you and John
