I've shot and edited some footage using the high compatibility lpowell patch, and now need to mix some of my footage with some SD footage as well. I shot the GH13 in 16:9 and the other clips are all SD 4:3. I'm using Sony Vegas PRO 10, wondering if anyone has any tips for rendering the footage to SD with Vegas? I tried a few presets, mainly the MPG NTSC DVD Architect settings, and wasn't sure if I was approaching this the best way, I'm a bit new to this. Just looking for a few tips before I spend several hours / days experimenting. Thanks in advance for any help.
