Problem is that the 720p Varicam files are actually 960 X 720. The instruction set in the code tells the application that it is 1280. Not all applications look for this instruction. Specifically Final Touch. When rendering to DVCPro HD 720 in Final Touch, there is a scale that occurs and if you look at the final compared with the original (by fading between the two in FCP5) you will see that the Final Touch version has been zoomed in by about 10%. They (FT) says that the QuickTime file set has a language that is passing along this artificial size and some applications dont/cant know the artificial size and must know the native size. Also the DVCpro HD 720 Codec has a quicktime handler problem that keeps you from being able to render pixel to pixel (the 10% zoom problem) apparantly the instruction set includes outside frame video pixels and not just active video pixels. FCP has been patched to handle the problem. So if QuickTime fixes the problem, it will then be unfixed in FCP... It's a pain in the arse!
