so hears my problem...I am using vegas 7 to edit m2t files in thier native form (1080 i) and all is well but due to the nature of the project of it being a short film i need it to deinterlace it in magic bullet suite in after effects (prefer it to vegas' deinterlacing). AE and MB accept HDV fine and i can apply the 25p filter fine but when it comes time to output im confronted with a flurry of codec options. Now the default is avi uncompressed and i know avi is just a wrapper but by rendering to an avi file im worried i will lose my 4.2.0 colour space and scared that some minor re-compression will take place seeing as im losing that '.m2t' extension and going to an '.avi' extension. There are options to output into cineform codec, sony yuv etc but i have the same fear regarding them all, i guess i was just hoping to see a 'm2t' codec output option but i guess not. The next obvious thing would have been to output to mpeg 2 but there are so many options and variables in AE of which i would have prefered vegas to handle when time to convert to a dvd readable mpeg 2 file.

Does anybody know how i can get my 'bulletted' video out of after effects whilst maintaing its 4.2.0 colour space and with no recompression? Thanks in advance
