Decomp 3

First of all I would like to mention that I've read the manual however it is difficult to understand for me, at least.:(

When do I have to use deinterlace ? It says when we do not have a real movie. Is it means that it is not necessary for DVD. Or if the info says deinterlaced?

Telecide: I need this to set up if I converting NTSC to PAL, an other words 30 fps to 24 fps. So basically I do not need this filter for PAL movies. Is it true?:confused:

Decimate: This is a dark site of my life. It looks like I can use in any case. NTSC-NTSC decimate(5), PAL-PAL decimate(2). Is it reducing the frames?:confused:

Thanks for spending time and explaining me, an undergraduate in this field, these thinks.:rolleyes:

Well I think these things are explained in the guides here at doom9 but I'll try to help anyway. :)

deinterlace is already done by the telecide command in decomb 3 (post processing), it removes interlacing artifacts (horizontal lines) from frames that are detected as combed (when using the default options for telecide). I would just leave it on because if you don't need it it won't run and if you do it will improve the video a lot.

telecide() reconstructs the progressive video stream from the interlaced one, if you don't know what that means read the DVD Basics section here on doom9 (*most* DVD's are interlaced because most TV's are interlaced - pls correct me if I am wrong) - it does NOT change the frame rate

decimate(x) changes the frame rate by detecting duplicated frames and removing them at the rate of 1 in x frames (30fps(US TV) to 24fps(Movie on film) is 1 in 5, the default), I wouldn't use decimate on PAL material (just encode at 25fps).

Hope this helps... the guides here are very good, you might think about reading them ;)

oops,
you only don't need telecide() when your video stream is not interlaced (it is good for both PAL and NTSC)
