I'm using Sorenson Squeeze 4.1 to squeeze a file I created in PPro 1.5. How do I tell Sorenson Squeeze that the file (an avi from PPRO) is in 16:9 format. It seems that after I'm done squeezing it down, it looks stretched. I'm squeezing it to an FLV.
Yes, if having the maintain aspect ratio button checked is causing issues, then uncheck it. Or vice versa. I imagine your source is anamorphic, and this will cause Squeeze to encode to the incorrect square pixel format sometimes.
