DVD Archicect Studio 5 recompressing compiled program streams?
Hello all.
I have Sony Vegas Pro 12 but use DVD Architect Studio 5.
I compiled a movie for a bluray and dvd. Movie was shot at 23.976 frame rate.
When using DVD Architect Studio 5, it will tell me it needs to recompile on Video track 2. I’m not following why it says this vs. video track 1, where my only video is located. Burning a Movie only disk, no menus. And if I process the disk, I do see it does recompress.
This is the case when I use the following templates in Sony Vegas Pro 12.
M2v – Bluray 1920 x 1080 24p 25Mbps (I adjust to do two passes)
Mpeg2 – DVD Architect 24p NTSC Widescreen Video Stream (add 2-3 pulldown and 2 pass)Funny, for DVD I did use the template Program Stream NTSC Widescreen (where it plays back at 29.97 frame rate, I don’t change it to 23.976) and if I burn that mpeg, it doesn’t recompress and plays back normally.
I also note that in DVD Architect Studio 5, there is no option when beginning a project to select anything with 24p, just ntsc frame rates.
Can someone advise me on what’s going on here?
Thanks in advance.

You just found the problem. The Studio version of DVD Architect doesn’t support 24p. This is because Movie Studio didn’t support it either at the time. You need to buy the Pro version of DVD Architect if you are going to use the Pro version of Vegas or else you must stick to what the Studio version supports.

Thanks, John.
I guess I can avoid recompression by rendering my 23.976 fps film as 29.97fps.
Again, I did this already as an mpeg2 and compiled, and the dvd plays back normally and looks good.
I could recompile the film as an m2v file and go 29.97fps to avoid compression on the bluray, but honestly, I’ve seen it recompressed and I’m still blown away at the quality. These renders have gotten the film into festivals so I can live with it for now.

Yea, it’s quite common to wrap 23.976 fps as 29.97fps. The process is called Telecine and is how all film was displayed on analog TV. It should look fine as you have seen.

In a situation like this, for example, where the original was shot in 24fps, and now you need the final video to be 30fps, what would be the best steps to take to “wrap” the 24 in 30 so that you can bring the project into DVDA to complete?

If you have the original timeline, find the proper template or fine tune one for your needs.

After restarting Sony Architect Studio 5, the option for 23.976 showed up for bluray. I thought it was there. That was bizarre.
It is strictly NTSC 29.97 though when it comes to DVD.

And also, on most digital systems (TVs and projectors), the displays have long since gone to something that doesn’t support interlace anymore. But they’re good at both scaling from interlace to progressive and detecting correctly-cadanced telecined video. So that pulldown from 24p to 60i is probably being reversed when you play it back… the primary disadvantage is just a little wasted space on the disc.

Use the MainConcept MPEG-2 template called DVD Architect 24p NTSC Widescreen video stream. If you open it up you’ll see that it has the frame rate set to 23.976+2-3 pulldown which means extra pulldown frames will be added to bring it up to 29.97fps.

It’s odd which features Sony decided to turn off for the Studio version. I can’t explain it.
