Movie studio -> DVDA -> blu-ray without DVDA re-encode?
I have an AVI file (1920×1080-60i uncompressed) that I want to convert into a blu-ray .iso file using Vegas Movie Studio HD Platinum v10 and DVD Architect 5.0. I’d like the blu-ray format to be a variable bit rate AVC and use a 2-pass VBR encoder with an average of 15Mbps and a maximum of 25Mbps to render the AVI.
Looking at encoders in VMS it seems like the MainConcept AVC/AAC encoder would do the trick.
However, when I feed the rendered output (via VMS “Make Movie”) to DVD Architect, DVDA insists on re-rendering the video at what looks like a constant bit rate, before writing the blu-ray .iso.
The DVDA help says (search on blu ray render) that AVC compliant media for blu-ray can be: 1920×1080, 29.970 interlaced, 16:9, 40 Mbps (max). It would seem the MainConcept encoded video meets these criteria.
I’m new to NLEs and just started working with VMS and DVDA under the 30 day trial, so if I’m doing something obviously dumb, thanks for pointing it out, but I’m pretty certain that avoiding a 2nd rendering is a worthy goal.
Is there something I need to do/set in VMS so that DVDA doesn’t need to do a 2nd rendering and will put the MainConcept rendered video ‘directly’ into the blu-ray iso? Is there a different codec I should be using in VMS that will let me output a VBR file with a average/max bit rate that DVDA won’t try to re-encode?
Thanks,
Brian

You need to use the Sony AVC codec with the Blu-ray 1920×1080-60i, 16 Mbps video stream template. This will produce a video file that is Blu-ray compliant. Then render the audio using Dolby Digital AC-3 Studio with the either the stereo of 5.1 template depending on your audio mix. Give the file the same name (just with the .ac3 extension) and DVD Architect will know that it’s the audio for the video stream.
Before you ask… No, you cannot use the settings that you want. These are the settings that work! DVD Architect is quoting what is “legal” for Blu-ray (e.g, up to 40Mbps). That doesn’t mean that Vegas Movie Studio can actually “produce” those files.

You sure can, in fact you should be able to export from VMS directly to a Bluray image file and bypass DVDA, (tools -> burn disc -> bluray) . You really don’t need to use both of those applications and would probably save time by cutting one of them out of the equation… As far as the second render is concerned are you sure it’s actually re-rendering the video and not just muxing it / splitting it into chapters? What is the size variance between the original avc encoded / m2ts file you are trying to reuse and the total size of the bluray image?
(Don’t listen to negative Nancies, anyone who tells you something can’t be done is probably just too lazy or too stupid to figure it out themselves. The guy looks like he just left a Bon Jovi concert for crying out loud, I wouldn’t be surprised to find out he doesn’t actually know what he’s talking about because he still hasn’t upgraded from VHS.)
