Vegas Pro 11 not fully AVCHD 2.0 compliant

I just paid a lot of money for Vegas Pro as I was hoping it would make it easier to render AVCHD2.0 files that would retain my camcorder recorded quality of 1920x1080 60p at 28 mbit/s.

The recent Vegas Pro 11 build added "Sony AVC format render template customization to support AVCHD 2.0".

The revised AVCHD 2.0 spec allows for 59.94p and 28 mbit/s. Yet despite the Vegas claims to support AVCHD 2.0, the SonyAVC customized template is limited to a bit rate lower than the spec. In fact, the highest bitrate allowed is only 25,999,360.

Seems like a false claim to me! Any thoughts?

It would be helpful to have a footage sample available which is recorded with a AVCHD 2.0 compliant camera and which contains a peak rate higher than 28 Mbit/s or an average peak rate higher than 26 Mbit/s. Actually I've never seen such footage.

"It would be helpful to have a footage sample available which is recorded with a AVCHD 2.0 compliant camera and which contains a peak rate higher than 28 Mbit/s I really don't have anything to add to this thread except to offer the following AVCHD 2.0 footage: 00058.zip (Panasonic TM700 1920x1080 60p).

The way I read the spec is that the bitrate max of 28 Mbps applies to total (System) bitrate of video + audio. Do I read this correctly?

Feel free to experiment or use this footage however you like.

Thanks for this footage. Analyzed with AVCHD Bitrate Viewer I see the peaks are at 28 Mbit/s and the avarage is at 25 Mbit/s (video only). So taken from this sample it looks like Sony AVC - using peaks of 28 Mbit/s and a max. avarage of 26 Mbit/s - is doing fine.

Yes, found that out the hard way trying to keep the audio sounding good at low bitrates I've managed to kill the vision with the Sony AVC encoder.

So, are we concluding that Vegas Pro 11 IS or is NOT AVCHD 2.0 Compliant?

As far as I'm concerned, Vegas 11 IS AVCHD v2.0 compliant.

From what I can see - it definitely is.
