1080i MPEG 2 rendering
I normally shoot my videos in 1920x1080i. When I render a Vegas Pro 8 project for a Blu-ray disc, I use the Vegas Blu-ray MPEG 2 template with a bit rate of 25 Mbps. Does this actually produce a true HD disc or does the AVC template produce better results. The problem I have is that when using the AVC option, Vegas almost always shuts down before the rendering process is completed. This is usually the case if I use crossfades and other effects. The MPEG 2 template always renders successfully. Thanks.

Bitrate for bitrate, 25Mbps AVC will be higher quality than 25Mbps MPEG-2. Still, the MPEG-2 disc is “true HD,” which is defined by resolution alone.
There are a couple of AVC options in Vegas: Do they all crash? Do you have the 9.0a update? (9.0 had a Main Concept AVC bug.) Finally, one workaround is to render out to an uncompressed intermediary. I often transcode to QuickTime (MOV) using the Animation codec (or PNG, but that’s a lot slower) and then render that out to AVC. It’s an extra step, extra hassle, requires a ton of disk space, but, meh, it works and it’s not like I have to sit around watching Vegas render or anything.
