I use Proshow Producer all the time and then export to Vegas for mixing with video and final rendering. If you want the best quality and also want to maintain color accuracy, the only way I've found is to render to Uncompressed AVI. You cannot render Compressed AVI such as Cineform or Canopus HQ if the file size exceeds 2GB without the file being corrupt. (You can search in the PSP Enthrisiasts forum in their Troubleshooting section). If the length of your project is too unwieldy for Uncompressed AVI, the only other alternative is a high bit rate MPEG-2. You can set your own bit rate--in the past, I've used 50 mbps. You cannot smart-render PSP MPEG-2 files in Vegas It will re-render, but with a high bit rate, your loss should be minimal. The main problem with HD MPEG-2 is color accuracy. If you look at a file rendered from PSP with MefdiaInfo, you'll see that it uses the SD color primaries (601) rather than HD (709). The result will be noticeable red-green color shifts. Probably, most people would not know the difference. So, if this is OK, then render from PSP with HD MPEG-2. Incidentally, the color shift problem also applies to their MP4 renders. You might try Quicktime, but I have never gotten that to work on my 2 systems, another commonly reported problem. This is clearly a problem Photodex needs to address, but seems unwilling. Bottom line, go with Uncompressed AVI or simply accept the color shift problems with HD-MPEG2. Good luck.
