1280x720 50p Render to Blu Ray?

Why not use Mainconcept MPEG2 wide screen. From memory all DVD files are interlaced. Try starting a new project (50i) and drop your .mp4 file onto it and test.

Edit: Oops Sorry read DVD instead of Blue-ray. Your 1280x720P file is OK for BD. Looking at my render templates I took a standard MC BD mpeg2 template and modified it to 1280x720 50P. (don't forget to remane & save). This gave me the videostream Audio ac3 pro. DVDA should take these files and produce a BD.

There are valid 720p Blu-ray templates in Vegas iirc.

Thanks for both answers!

diverG I will try your suggestion.

Musicvid, the choices I see for BD are 1440x1080 and 1920x1080 and are either 24p, 50i, or 60i for Mainconcept. Would I chose 1440x1080 50i?

Thanks!

prejto, read post # 4 here.

vkmask & Cornico, Thanks very much for your help. Much appreciated!

Cornico, I tried your suggestion and I ended up with a file that will not play in any stand alone player (like VLC) and will not even load back into Vegas or DVDA. I have no idea why this failed. I did try several times. I've attached a screen shot. Do you see a mistake?

Vkmask, I followed the link you pointed me to and I was able to produce a 1280 x 720 50p m2v file that imports to DVDA and does not need further rendering. Many thanks for that!

When you rendered using the customized Sony AVC/MVC render template, you should have produced a elementery video file with an avc extension. Many applications won't play .avc files, but DVD Architect is happy to injest it into an AVC Blu-ray project just ike the .m2v file for an MPEG-2 Blu-ray project. Versions of Vegas Pro back as far as 9 will handle .avc files. In all cases with elementery streams, you need a separate audio file.

Thanks John,

I tried again to add the Sony AVC file and got a long spinning cirle. This time I just waited and after 5-6 minutes it opened. (Is that normal to be so slow?) Also, another problem (of course) is that my rendered audio won't open or load. It has the .ac3 extension from the Vegas render. I have it named exactly the same as the video file differing only in the file extension. I cannot add it manually either. If I render to .w64 it does open. Is there a difference between Pro & Studio ac3? Thanks,

Peter

A render with Sony AVC gives no m2v, but avc. You followed NOT my suggestion.

edit: I see what the confusion was. I mixed up the two suggestions/names. I corrected the post above!

I'm sorry if there is any misunderstanding in what I wrote. I did generate an AVC file and eventually it did load into DVDA. It just took so long to load that I thought it wouldn't and initially gave up. So, your instructions are fine and thanks for that. For some reason though I cannot get the rendered ac3 file to open with the video.

Now I have 2 templates that work fine for the video (MainConcept AVC and Sony m2v). Is there any advantage to using one over the other? Both appear to look pretty similar at default bitrate settings.

As far as progressive scan goes, you can only do 24p on blu-ray to the best of my knowledge, unfortunately. A stupid oversight when they made the BD spec, but it is what it is. If you can't find any 720p blu-ray templates, just render it as 1080p24. Or, just let DVD Architect do the encoding and then you'll know it'll conform to spec, even though DVDA encoding is very slow... it's actually higher quality than using Vegas, especially when it comes to scaling video (at least that is how it was in the past, I haven't tried doing 1080p>480p downsamples in vegas in a while, they may have addressed that in recent updates). I know in the past, downsampling in vegas produced a nasty screen door effect, so I just adjusted my workflow to make DVDA do all of my downsamples to DVD from the 1080p Blu-Ray files I fed it for the BD discs.

I see you found some templates that worked... AVC is always going to be better than M2V. You're talking about using a 20+ year old codec with M2V vs. a much more modern one with AVC. You'll get higher quality at smaller file sizes/bitrates with AVC.

These are the valid Blu-ray formats:

DVD Architect will pass them thru if prepared as elementery streams in an editor.

Yes, it can take quite a long time for DVD Architect to massage avc files.

You should be able to drag an audio file with any name to the timline if you focus to the video file you want to pair. Hint, you can drag lot's of different audio files to the timeline as in different languages, director commentary, etc.

AVC is more space efficient, but MPEG-2 will produce an absolutely acceptable Blu-ray with a less capable computer in less time.

There are differences between the Dolby Digital Pro and consumer render templates. The pro version is the one to use. Search the forum for best settings.
