When exporting from Premiere CS3 to Squeeze I was told I would get the best results if I used a uncompressed format. So I tried exporting the movie using "uncompressed Microsoft AVI". It turns out Squeeze cannot handle that format it's a codec called "Optibase Video Pump" and is not supported by Sorenson.
Other settings like the "Microsoft DV AVI" restrict the screen width to 720x480 and "Microsoft AVI" appears to use a compressor.
Any suggestions or thoughts on exporting to Squeeze would be appreciated.
