It took me two weeks of back and forth with SCS to get an answer to this same question. Here was the final response:
At lower resolutions, the Sony AVC encoder only allows Vegas to offer the Baseline profile, which isn’t Blu-ray compliant. 1440×1080 and 1920×1080 AVC renders should be seen as compliant, because we can use the other profiles.
Also, you stated, “As an aside, it would be extremely helpful if DVDA told us WHY a clip is believed to be not compliant because in cases like this it isn’t clear, and it would help with the troubleshooting.”
Our Developers have found this to be an extremely helpful suggestion, they are hoping to implement a similar feature in future release of the software.
So, you will either need to upconvert your MTS footage to 1440×1080, or 1920×1080, or render with the Mainconcept MPEG Blu-Ray templates. This limitation on the Sony AVC encoder seems artificial to me, but I don’t know anything of its internals. Maybe we will see this change in a future release.

Wow, I remember using snagit a hundred years ago. It may have been with DOS, or maybe Windows 3.0. Thanks, I’ll take a look at snagit 9.0.

jr, nice response.
Care to share how you do the “torn edges” on the screen shot you posted? I can imagine a not-so-easy manual way to do it in PS, but I bet you have something easier.

Spot, I am very confused. The list which includes “1280×720 i” is straight out of DVDA help file. The help says you can render compliant footage to any of those formats using 3rd party products.
Regarding what will and won’t work in DVDA – I can create an AVC template in Vegas for 1280×720 23.970p and the render shows up as non-compliant in DVDA. I can take a 1280×720 23.970p MTS file from my camera and drop it into DVDA and it IS compliant.
It looks to me like that entire section of the DVDA help file is misleading or bogus.
It would be very helpful if DVDA identified WHY a clip is non-compliant so we might be able to adjust the render.

Just add a 2nd cookie cutter and position it over the 2nd face.

Tnanks Spot. Of couse, not what I wanted to hear, especially since DVDA does apparently support it if I render from a different application. I do have followup questions:
1. I can create a custom template that appears to perfectly match one of the DVDA supported formats, but I still get the recompress. Is there any way you know of within DVDA5 to see a comparison of project and media properties so I could tell which property is out of compliance? This would be especially useful if you were using a 3rd party tool to create compliant video.
2. Are you aware of any video property inspectors (like the freeware VideoInspector)that I can use to inspect the AVC clip properties?
3. I believe a workflow that may work is render in Vegas using my custom 720p24 AVC template and take that clip to Encore CS4 which accepts it as legal. But I want to burn this short clip as blu-ray to standard DVD media, which Encore doesn’t support. If in Encore I prepare to blu-ray ISO image, can I then use DVDA to burn that ISO to DVD?

jr, I recently read an After Effects post making the argument that if you have 8 cores, you should consider getting 32GB ram. The point was that when editing HD and spreading it across multiple cores, each core will want to use 2GB just for the video, and the other processes that are distributed across the core should be provided with 2GB headroom. While this is certainly way beyond what the OP needs, I would appreciate your insights regarding how much ram an I7 hyperthreaded quad (8 render threads) should have. The reason I ask is we frequently see recommendations to cut Vegas 9 back to one render thread because of stability issues. Could the stability issue be because we might typically only have about .75GB ram per thread (eg, 6GB total ram)?

John, does Sony MXF use intraframe compression? How do you feel about using it for editing?

I’m not certain if this works with mts but it is worth a try. Put your text in its own veg and prerender that veg. Then, each time you need the text in your other projects just put the text veg in your timeline. If smart render works for mts, Vegas won’t need to render it again.

If you need menuing and more sophisticated bluray authoring you will need the pro version of vegas which comes with DVD Architect.
Like you, I also shoot 720p AVCHD. I have a support request in to Sony Creative Software asking why there is no 720p24 template in Vegas. Major oversight I would say. You can’t even customize one because you can’t select 23.976 framerate. I would expect this to be addressed in Vegas 10, but I have no real insight into that, or when it might be available.
However, to my surprise, you can put out of the camera 720p24 footage in DVD Architect and it handles it properly. You just can’t edit it first in Vegas.
I see that you are using 64 bit OS. I’ve found Vegas 32 bit to be more stable with my AVCHD footage than Vegas 64 bit. Your mileage may vary.
