If you want mpeg then render a M2V from Vegas. If you want h.264 then render a AVC from vegas. In each case render a SEPARATE audio file and inport that and the video file to DVDa. I have found that Dolby Digital works the best... either DD Stereo or DD5.1

Rob, assume you have an AVCHD 720p24 source. How would you render that for blu-ray? For the life of me I can't get a video render out of Vegas 9c that doesn't get recompressed in DVDA. I've tried both M2V and AVC renders. If, on the other hand, I drop the AVCHD 720p24 source clip on the DVDA timeline it will prepare/burn straight to blu-ray without recompression.

i would also like to know what settings are used for encoding to 720p24 Blu-Ray as there is none in Vegas for 720p24 or 720p23.976.

it doesn't seem unreasonable to expect the (otherwise identical) 720p30 and 720p25 presets would work for 24p if ONLY the framerate is changed... and yet it doesn't.

has anyone successfully rendered a 720p24 file using Vegas or any NLE for DVD-A?

alternately: is there a better way to get where i need to go? i have a number of RGB QuickTimes that need to be put on Blu-Ray (720p24) for playback.

the direct render off the Vegas timeline (Burn Blu-Ray Disc) sucked: mosquito noise, pre-smoothing & blocking artifacts. (didn't help there is no 720p24 offered in Vegas so i had to pick close equivalents... sigh)

i am considering rendering the RGB QT's to YUV QT but that's a LOT of extra rendering which would still have to be recompressed in DVD-A.

sooo, any practical options for getting RGB QT to 720p24 Blu-Ray?

If you have access to Final Cut Studio, its Compressor produces 720p24 H264 Blu-ray files that are accepted by DVDA. Change the .264 file extension to MP4 before offering the file to DVDA. It will not be re-compressed.

DVDA is the most backward authoring program out there I believe.

I've resigned myself to simply taking my high quality masters into DVDA and letting it do the compression since it has such a problem with compression done elsewhere. And be warned, if you try to do an AVC encode over 16Mbps or an Mpeg2 encode over a certain bit rate, it will get most of the way through the process and then give you a buffer error.

Nothing but trouble.

ok... so for 1280x720p24 what format is there that makes DVD-A happy?

it isn't any MPEG-2 or AVC format from Vegas or 10-bit YUV QuickTimes (DNxHD 1280x720@23.976)... these crash DVD-A once you go above 10-15 files.

thx for the FCP tip but i have no regular access to it here... i'll keep it in mind tho.
