I've search the forum for this and could not get a true answer I can understand so I'm asking it again. Sorry if it is repetitive. I have already read the Sticky article on this but I'm still a little hazy on the information.

I am trying to covert the Season Series of the show 24. The Video type is FILM 90% and moves up and down, but started out at NTSC. (DVD is NTSC) The frame type is progressive, but after saving it, and previeweing the frames, I can see interlaced frames, about 2 out of 5 frames are interlaced.

My question is whether this is telecined or interlaced, and if so, how can I tell the difference bewteen interlaced video and telecined?
The aricle made it clear on how to tell if a video is telecined, but how do you tell if it is interlaced?

Thank you ahead for any replies.

It's telecined, so you'll have to un-do (inverse) telecine it. I strongly urge you to use decomb instead of Forced FILM, as Forced FILM is pretty lazy and only does the FASTEST possible job at inverse telecine. It's good for movies that are 98%+ FILM, but at 90%, you're better off using decomb.

Interlaced video will be totally interlaced, not just 2 in 5.

In GordianKnot, the way to use decomb is to select 'inverse telecine' right before you 'save' the avs script before encoding. Before doing so, I recommend upgrading to decomb 4.01. I believe this is the current address of Donald Graft's homepage: http://sauron.mordor.net/dgraft/

If that doesn't work try this: http://www.doom9.org/Soft21/Filters/decomb400.zip

Hi-

The aricle made it clear on how to tell if a video is telecined, but how do you tell if it is interlaced?

Do you mean the Article (http://www.doom9.org/ivtc-tut.htm) that says this:

If, in every 5 frames, you see 2 interlaced frames and 3 non-interlaced (progressive) frames, then it has been telecined and can be IVTC'd (Inverse Telecined). If you see that every frame is interlaced, then it was created at 29.97fps (actually 30fps). These can't be IVTC'd. If you try, you'll be dropping non-duplicate material, and it will play very jerky (most obvious during a scrolling or panning scene). They can only be deinterlaced.:)
