Hum, thanks. But then, I would like to know, when configuring Decomb for example, if I need to assume that the video is 3:2 pulldown or not. Because 90% of the video is PPPPI, and 10% is 3:2 (PPPII). Do you know any special settings that would be usefull dealing with only pure PPPPI ? Because I could specify manually an determined range of frames that there is only and pure PPPPI (with a special configuration that would handle PPPPI 4:1) and an determined range of frames that there is only and pure PPPII (with a special configuration that would handle PPPII 3:2). Sorry if I did not make myself clear, english is my second language...
