CCE why forcefilm?

Why is it recomended that i force film when dvd2avi shows the source is 95%film. Why are we forcing 24 fps when the source is 30 fps.

Also what is a IVTC mentioned in getting the best out of cce.

I've encoded a interlaced source and disabled the force film button, movie came out fine without me even knowing what a IVTC is.

>95% FILM means (most of) the video footage is stored natively in the MPG stream as 24 (23.976) fps progressive material. The player applies pulldown as it decodes the video to turn it into 30 (29.76) fps. Using force film just tells DVD2AVI to *not* apply pulldown as it decodes, giving you access to the native progressive frames.

Generally it's good practice to preserve progressive material where you can. It's a two-fold gain; progressive video compresses better than interlaced video, and 24 fps requires less bitrate than 30 fps video (for a given level of quality). That said, if you're satisfied with the results you get, that is all that is important.

On a similar, related note, IVTC is a way to restore 24 fps material when DVD2AVI shows less than 95% FILM. However, it's only appropriate for footage that was originally shot on film (or for cell animation).
