I just found out that doing AVC nothing over 15 Mbps is allowed and gets recompressed. If I stay with stock Sony AVC @ 15Mbps, it does fine and not re-encode. If I bump it up, DVDA recompresses. The help file says it will accept up to 40 Mbps. Complete BS.
My M2t's do just fine. AVC (h.264) is another thing. Make sure you are selecting which format you want to work with in the properties settings in DVD A. Make sure it says MPEG 2 for your M2T's.
"So, is anyone else having re-rendering problems with DVDA5? I've been stockpiling rendered projects (using the 1440x1080 60i template, which applies smart rendering to my m2t assets) in anticipation of authoring with 5. It would not be good if DVDA5 wants to re-render everything."
As said in the DVDA area, that is not correct. HDV2 footage is not in compliance with Blu Ray, you have to use the Mainconcept mpeg2 template "Blu Ray 1440x1080 60i", what will not be recompressed at all in the DVDA5.

No BS. As said in the DVDA forum, the Sony AVC encoder templates "AVCHD 5.1" are limited to 15 mbps. If you use the templates "Blu Ray 1440x1080", you can go up to 20 mpbs. The limitation of 20 mbps derives by Vegas 8b, but not by the DVDA5.

I just replied in DVDA forum, IT DOES recompress anything over 15Mbps on the Sony AVC Blu-ray 1440x1080 template! Try it. I'm not even messing with AVCHD.
Well, this totally sucks. I could author HD-DVD from M2Ts with no recompression. Now that we are stuck with BD, I am forced to recompress when I author. I knew there was a reason I wanted HD-DVD to win the format wars....
I just tested two .m2ts with AC-3 I had previously rendered from Sony Vegas and one from Adobe After Effects with no audio. Both used the blu-ray rendering templates. DVDA 5.0 did not re-compress them.
As said, that is a limitation of the Sony AVC-Encoder in Vegas 8b - if you change the size to 1920x1080, or if you increase dat rate, the material is recompressed at the moment. That should be overcome with upcoming AVC encoders in Vegas 8c - as written in the comments to the known issues.
It is not a pure limitation of the data rate.
Recompression does not take place, if you stay with exactly with the Sony AVC templates "Blu Ray 1440x1080 50i/60i", and if you combine that with AC3 Pro audio.
Recompression does not take place, if you use the Mainconcept mpeg2 encoder - for 1440x1080 50i/60i, for 720p with 24p, 50p (and also 60p, I think), for 1920x1080 50i/60i. The Mainconcept mpeg2 encoder offers more, at the moment.
My project used the Standard HDV 1080-60i (1440X1080, 29.970 fps) template. For Video I went File -> Render As -> MainConcept MPEG-2 (*.mpg; *.m2v; *.m2t; *.mpa) -> Blu-ray 1440X1080-60i, 25 Mbps video stream. I then hit Custom -> Video Tab -> Video Quality High (31). Audio was done as File -> Render As -> Dolby Digital AC-3 Pro (*.ac3) and then either Stereo DVD or 5.1 Surround DVD.
Is this really any different from what DVDA has always done? For DVD files, If you strayed even slightly outside of the "Architect" templates, DVDA re-rendered the mpeg files. Once you hit that "Custom" button, you knew that DVDA was going to re-render. This just seems like a continuation of that process... just with Blu-Ray and not just DVD. If that's the case here, it's just going to be the fact that you have to use the templates exactly has given, or else expect a re-render.
I'm not ready for BD quite yet, so I tried creating a new DVD from an old project using V5 and the old "There are two discrepancies in some VMGM/VTSI_MAT tables." still shows up when I check it with PgcEdit. I guess I will still have to run it on every disk I create.
Sorry if this is slightly off-topic here, but this thread being alive, I thought I'd draw your attention easier.
Something must have happened to my XP installation (Vista is still OK in this respect). After I burn an iso image using Vegas "Burn BD from timeline), and mount it in a virtual drive - I cannot access it with XP Explorer (it either says the drive is empty, or that the content is corrupt).
I used to do it frequently when importing m2ts files into MovieFactory 6plus to author my BD's with menus, chapters etc - now it cannot be done!
The only thing that changed with my XP installation is that I have applied the SP3 - anyone experienced this as well?
BTW, this is exactly the same Explorer behaviour as when I try to open a BD-ROM file structure, with the disk in my BD burner. Interestingly enough, BD players (like Nero or PowerDVD) don't complain and play BD content from these drives just fine!
For you folks that say your streams from Vegas are getting recompressed:
Do you get the warning notifications before proceeding that the files will be recompressed? Because I don't see that, but I do notice that DVD5 now says "RENDERING" while preparing the BluRay files.
Well this is interesting, and maybe I missed it in another post, but with HDV footage from my HC7 rendered in Vegas 8b to BluRay 1440x1080-60i 25Mbps, it flashes on the preview window "No recompression required".
(After transfering that *.m2v file into DVDA5 no recompression is indicated in the "Optimize" menu, but it does still go through "Rendering" and then "Preparing".)
I tried rendering a snippet from an m2t (Canon HV30) to HDV 60i using the template, it smart rendered in about real time on my laptop "no recompression required" was showing in the preview window except at the beginning and end of the render.
Rendering the same snippet to BD 1440x1080 25mbps 60i using the template took maybe 20% longer. During that time "no recompression required" flashed intermittently in the preview window. Anyway, it seems pretty clear that whatever happens, it isn't "re-rendering" as I ususally think of the term.
When I dropped the HDV render into DVDA and went to Prepare Disc, I got the warning saying it would recompress. When I got the BD render into DVDA, I didn't get a warning.
Prairiedogpics - perhaps the "Rendering" refers to the menus? I can't remember the messages I would get when authoring a SD disc,
nolonemo, I saw the same things you saw with footage from my hv20. When I saw the warning to recompress, i aborted and re-rendered a file using the default mainconcept bluray template. The render also took about 20% longer and I occasionally saw "no recompression required" on the preview screen.

This is what I've been using and my videos do not getting recompressed. Mpeg-2 using any of the Blu-ray ... templates should not recompress (at least they don't for me).
"The overall bit rate for ‘My_Name' is greater than 28 Mbps. The overall bit rate is too high for burning Blu-ray onto a DVD."
Hmm... The above message worries me, as the m2v clip was prepared in Vegas using its default Blu Ray 1920x1080, 50i, VBR 25MBps template - and yet it still needs to be recompressed!
Unless I mis-configured DVDA 5 (why does it say "on DVD"?)

Didn't see this one answered below. The reason is simple, your XP installation doesn't have an UDF 2.5 driver. XP can not read Blu-Ray disks unless you add the driver. It usually comes with your Blu-Ray drive,alternatively you can use Nero or similar.
