The source clips have got real problems. The AF-100 was profoundly grainy in the 5-30 IRE range. I used Neat Video to clean it up. It worked, but theres no free lunch, its left some over simplified gradations from light to dark. and dark to dark. Its very subtle at full 1080 prores but when I compress them the colors become more simplified and look like banding. Like chips on a color chart representing stops from black to white. Blocky may have been the wrong word. This clip will be uploaded to a youtube-like site, it uses a flash encoder. the site also accepts Mpeg2. i own sorenson squeeze, is there any tips using the same concepts we discussed but with squeeze? Or should I use a more powerful Mpeg 2? I basically want to find a compression that has more values and more colors between black and white. I want LESS compression, the clip can be up to 1.5 GB. Basically I do not want to compress this video, I like the way it looks as a 5.85 GB file at pro res 422 HQ. You tips have helped tremendously. the latest compression looks that best at 293 MB multipass, 9999, frame reordering checked. Any tops pn a compression that reduces the colors less? for instance I like how it looks with Prores LT. But that is not accepted as a format by the flash encoder.
