When I've made a NTSC DVD I've used the same audio file. Can't imagine it'd be any different going th other way around.

From Vegas I'd render:

1) Audio as .wav 16bit/48KHz
2) Vision to mpeg-2 PAL
3) Vision to mpeg-2 NTSC Use Best and De-interlace set to Blend or Interpolate depending on how much motion you have.

Make PAL DVD using 1) & 2)

Change DVDA project properties to NTSC. Replace 2) with 3). Burn DVD, job done.

If you need, audio could be ac3, again will not make any difference.

Reverse above obviously if going the other way.

Vic and Bob,

I am running into a problem with this right now in my thread regarding a DVD that has to go to Italy.

DVDA wants to re-compress the AC3 and I can't figure out why?

Excerpt my last post in that thread:

The AC3 is the same file for the NTSC and the PAL version. Rendered the video on the Vegas timeline to NTSC Mpeg 2 and then to PAL Mpeg 2 using the DVDA templates.

Digging back through the memory banks I may have only done the swap vision only trick with a .wav file and I must confess that at the time I was kind of surprised that DVDA coped. In your other thread as others have noted you sure don't want to be recompressing ac3 if you can avoid it. Simple suggestion, change your project to PAL and render a new ac3 file.
It's possible there is inside the ac3 file something that DVDA needs to hold sync as it muxes the two data streams, only a guess really. When you render audio there's nothing in the render settings that specifies a frame rate or TC so maybe Vegas picks that up from the project settings like it does the de-interlace method.

One other thing worth a mention. NTSC's 4:1:1 doesn't sit too well with the DVD's 4:2:0. If you've shot NTSC DV not much can be done however if you've shot HDV then going from a HDV source directly to mpeg-2 should help a lot, not to mention the resolution issue. Also a good reason to ingest HDV rather than having the VCR do a downconvert.

========================
Just tried it. DVDA still wants to re-compress it.

None of the others in that thread who said they made PAL versions from NTSC video mentioned this problem. Has to be something I am doing incorrectly, but I can't figure out what?

Just tried with 1 minute of video.
PAL Project, saved as PAL.veg in Vegas 7
Encoded ac3 to PAL.ac3
Encoded mpeg-2 using DVDA PAL template to PAL.mpg

DVDA 4.0
PAL Project.
Added PAL.mpg to empty menu. Saved As PAL.dar

Open up PAL.veg
Changed to NTSC project setting, Saved As NTSC.veg
Encoded ac3 to NTSC.ac3

DVDA 4.0
Opened PAL.dar
Saved As NTSC.dar
Changed Project Properties to NTSC
Replaced Video of PAL with NTSC.mpg
Under Optimise DVDA says video and audio are complaint.
Tried Prepare, No errors or warnings.

Run out of ideas as I can't repo your problemo, sorry.

Thanks for trying Bob.

I really appreciate that.
