Im using compressor 3.05 I have a 2min 48 sec video shot in HDV 1080i
Ive made up a hd web clip for youtube at 720p and the file is 101Mb
Seeing as youtube has gone 1080p I thought Id have a go and see what its like. The file is 821Mb is this correct?

Im using these settings for the 1080p

I don’t see much point in delivering 1080i as 1080p (due to the deinterlace step), you are better off doing it as 720p.

YouTube 1080p is there for when your source content is 1080p
