I knew it... Sony has a bug in a new release!

DVD A 5.0. No matter what I do, I can't export a AVC at bitrate over 15Mbps and it be compliant in making a Blu-ray! Even just choosing the Sony AVC 1440x1080 15Mbps template and changing the bitrate to something higher....

DVD A says it will accept a max bitrate of 40Mbps... they lie!

That is not correct. You can export from the AVCHD 5.1 templates of the Sony AVC encoder, and here you are limited to 15 mbps. By the way, at the moment it is not a good idea to use that at all - since the audio part of the AC3 studio encoder will be recompressed too (better to use the AC3 Pro encoder).

But what you can do is to use in the Sony AVC encode the "Blu Ray 1440x1080" template - here you can go up to 20 mbps at the moment, what is completely fine for AVC. Futher developments will take place in Vegas 8c very likely.

If you wish to go to 1920x1080, at the moment you have to use the Mainconcept mpeg2 encoder.

DVD A WILL recompress when I go above the 15Mbps! I'm using the Pro AC3 for sound. That template you mentioned is the one I am using and just changed the bitrate higher and that was all the changes I made to it.

But that is not a limitation of the DVDA, but a limitation of Vegas 8b!

Take the Mainconcept AVC encoder - here you can encode with 40 mbps. That can be imported in the DVDA, but will be recompressed since mp4 is not supporte by the DVDA without recompression. But it is possible to use 40 mbps.

To overcome that with the Sony AVC encoder, you will have to wait until Vegas 8c very likely.

Just played my test disc and 15 Mbps with Sony AVC looks pretty good.

I noticed this as well, and was a little surprised. I am hoping those that say the problem is the MP4 container that is the problem are right and that the 8.0c upgrade to Vegas will fix this. Right now it is not possible to burn AVC to BD at higher bitrates than 15M with DVDA and Vegas 8.

Hmmm. I have Premiere Elements as well, it can encode AVC to m2t I think. Maybe I'll try that tomorrow and see if DVDA will avoid re-encoding this.

This one had me a little annoyed for a little while. MPG-2 is fine for now though, so I am generally reasonably happy with the product. Other than the Blu-Ray stuff, I don't see much new in DVDA, haven't really read the readme and the docs yet though. Anything else exciting I should be looking for?

Oh, and Thanks Sony!

Yes, would be interesting to see if the Premiere Elements AVC material is accepted without recompression, and what datarates can be used.

For me there is no doubt that changes in Vegas 8 will improve the situation very likely.

Another new feature are the preview capabilites on an secondary monitor.

"Another new feature are the preview capabilites on an secondary monitor."

I was impressed! They've *finally* dropped the firewire requirement in DVDA. :-)

Then again it'd be kind of hard to preview HD otherwise, so my enthusiasm is probably over the top - apologies... Just an old pet peeve I'm glad to see remedied.
