Sonic Reel DVD came with my new version of Avid Xpress ProHD, but I've never sucessfully been able to use the program. The problem is, I think, that I'm not able to send audio and video out of Sorsenson seperately, which what Sonic ReelDVD requires. Any suggestions? Thanks.
In the MPEG-2 settings window of Sorenson you can choose Elementary Stream. This will cause Sorenson to output seperate files for audio and video.
Hopefully that will work for you. I haven't used Reel DVD is many years, but it seems like it could take a single file with audio and video, it would just have to demux it first, but I could be mistaken about that.
