I've tried to capture two episodes and have a question. The series has not been released on DVD, but those who may have tried to capture it may know the answer. :) So, there is my question...is it progressive or interlaced? I've applied different filters (using Decomb) but can't really figure out if the source is video - really interlaced, or film, that is, progressive. :confused:

p.p.s. If you lived in the us you would never have this problem as you would be able to properly ivtc ER. I wonder if american capturers have similar problems with uk/european tv shows?

Well...what a nice post this is! In fact, "ER" is likely to be shot on film. I've found some information on the IMDB: Plus, I noticed that some portions of the captures were truly progressive streams, whereas others were "interlaced"...rather telecined, to be precise. It may sound surprising, but it happens at times. When applying "Telecide()" or "FieldDeinterlace()", and even when disabling postprocessing in the first case, I've got similar results, except the few combing artefacts left if I disable postprocessing. As for films, they are sometimes telecined, sometimes not. The stream may be a truly progressive one (just like video on DVD). Thus it is very easy to capture it through my capture card (DC10+) and encode it without using any deinterlacing filter at all (the source is digital satellite, which provides excellent quality - especially the TV channel "Canal+"). And if the stream has been telecined, I use Decomb and its "Telecide" feature that works great. Then encoding takes a little more time, of course...

I don't really understand what can be ivtc'ed when your capture is 25fps interlaced. Is the result still 25fps, or do you decimate it to 24? If it is still 25fps, then what is the benefit of telecide() over a normal deinterlacer?

Hi there. Telecide() does not perform an ivtc operation on its own, its main role is that of field matching - in order to provide progressive frames. A movie that is captured in a pal country can be EXACTLY recovered as it was (i.e. 24 fps progressive). Movies are usually just speeded up from 24fps to 25 fps then transmited interlaced. Telecide will just match those fields back up again (but it is very clever in that it can accomodate field switching etc..) at a frame rate of 25fps progressive. You could if you wanted to change the frame rate to 24fps if you, but i know of no one who can be bothered to shrink the audio and remux: simply not worth bothering. So there you have it - telecide is perfect for these sources as EVERY frame is recovered perfectly PROGRESSIVE (only 1/25 faster than the original film). See : Thanks

@theReal Yes, that is right.

theReal: Yes...try and see "Telecide" for yourself. You'll be amazed by it, since it does a wonderful job. I've used it for a month or two, and I only wish I had the idea of using it before. I thought IVTC was just related to DVD and NTSC. Well...I should have thought about this telecining process before! This "Telecide" filter is the appropriate filter, the one I needed to "deinterlace" my captures. :)

By the way...I was wondering: How do you pronounce the word "telecine"? :confused:

Thanks for the link. ;) I perfectly know what the IPA is...In fact I am an English graduate. :D But "telecine" is a technical term. It is the kind of word you don't find easily in a basic dictionary.

I've just found that:
