I am trying to render a 2 minutes of video -- about 40 events with dissolves between them -- at the Sony AVC setting in the AVCHD format 1920 x 1080 NTSC. The video was shot on a Sony HD camera and the original clips are in the ARCHD format.

The rendering gets about one-third of the same thru and stalls, then closes Vegas. It's not crashing my computer, just the editing program.

I've rendered the same two minutes in SD with no problem, looks fine; I can place the one-third rendered piece of HD on the timeline and it plays fine and looks fine. I've even replaced some of the events around the area where it stalls, although it is not the same exact place each time.

Anyone have an idea what's going wrong or a solution?
