29.97p projects

DVD Architect 5 doesn't seem to have a setting for 29.97p for DVDs or Blu-ray. Is this just a limitation of encoding in DVD A 5 versus doing your encoding in Vegas Pro 8.0c instead? Just like the one-pass VBR instead of two-pass VBR?

It will accept progressive encoded MPEG-2/AVC at 29.97p, right?

Thanks.

Any further info on this?

I just tried putting some Vegas Pro 8.0c encoded MPEG-2 1440X1080/30p into DVD Architect 5.0a, and it insists that it must re-encode the files.

There's gotta be a way to do 30p in DVD Architect 5, right?

Thanks.

As far as I know DVDA will only allow files that are in accordance with the Blu-ray specs to be used as is. Anything else will need to be transcoded to one of the Blu-ray spec formats. 30p is not allowed in the Blu-ray specs so it'll need to be turned into 60i.

You can find the relevant specs in a white paper on the Blu-ray Disc Association's website. But to save you reading it all, the formats are:

1920x1080 59.94-i, 50-i (16:9)
1920x1080 24-p, 23.976-p (16:9)

1440x1080 59.94-i, 50-i (16:9) MPEG-4 AVC / SMPTE VC-1 only
1440x1080 24-p, 23.976-p (16:9) MPEG-4 AVC / SMPTE VC-1 only

1280x720 59.94-p, 50-p (16:9)
1280x720 24-p, 23.976-p (16:9)

720x480 59.94-i (4:3/16:9)
720x576 50-i (4:3/16:9)

OH! That certainly would explain it! Thanks for the info and the link.

So how does one put HD 30p projects to Blu-ray? I've shot some projects in XDCAM HD in 30p mode, I like the look of it.

If I just tell Vegas to render it as 60i, will it do anything weird to it? I mean, progressive stored as interlaced is just two fields from the same image in time, so there shouldn't be any problem and it should look exactly the same as the native progressive, right?

BTW, based on the table of specs, the 1440X1080 resolution for Blu-ray is ONLY for AVC/VC-1? But Vegas includes MPEG-2 templates for Blu-ray in that resolution. That's the resolution I prefer to use so I let the player scale up my XDCAM HD, which is natively 1440X1080, instead of making Vegas scale it up and make the compressing of it less efficient. DVD Architect also seems to allow the 1440X1080 in MPEG-2. Wonder if that's a compatibility issue for players?
