Thanks Mark! It's a short film thats trying to mimic a 'film look' so deinterlacing is kind of a must. One thing im still confused about tho, if i output to the cineform hd codec with a .avi tag that will will keep me in 4.2.0 right? but seeing as i will be getting a .avi tag no matter what, will it make a difference if i output it as .avi uncompressed? I only ask as it seems that trying to save my video with the cineform requires me to purchase it in full as vegas 7 comes with a standard one but dont think u can render with it from other programs unless you buy it. I may be mistaken about that but wouls still be interetsed to know the difference between .avi uncompressed vs .avi cineform hd codec.

thanks
