What framerate are PAL SD/HDTV transmissions?

I think there isn't a set standard for PAL HDTV. So far what I've read seems to indicate PAL HDTV is still 1920x1080, but at 25fps instead of 29.97. Technically there is no standard for 1080p24. People are doing an Inverse Telecine on the 29.97fps video and then discarding the duplicate frame. This gives you 23.976fps. This only works for shows that have a 3:2 pulldown applied. There are a lot of stupid people out there trying to IVTC true interlaced material.

since the standard comittees couldn't agree on a HD standard we don't have one in PAL land :/ But regular DVB broadcasts are all 25fps.

Ideally you shouldn't be changing the frame rate at all. The nice thing about PAL is that its 25FPS. More often than not, filmed 24FPS is simply sped up a slight bit to make it 25FPS. This does cause a shift in audio pitch, but its quite small and not noticeable unless you have the original 24FPS audio track to compare with. We don't have to deal with all the nastiness of telecining as the NTSC viewers do. At times I have seen hideous conversion jobs done though. I've seen a 24FPS show telecined to 29.97 and then down converted to 25FPS. Frames get blended to hell and in general, there's not a lot you can do to repair something like that. Rarely you see a show that has been converted by taking the 24 FPS film and adding in a repeat field to nudge it up to 25FPS while maintaining the duration and audio pitch. Hardly see that these days though. A lot of TV shows from the US are recorded at 24FPS or 23.97 and simply sped up for PAL viewing. At times you will see shows with apparent interlacing from the US (Touched By An Angel shown on 9 in Australia is an example) or where the odd scene or two appears interlaced. More than likely its just the field ordering in the show is a little broken. decomb's or mpeg2dec's telecide() function will fix that nicely in avisynth, or the DFOC filter for virtualdub giving you nice 25FPS progressive frames with very little trouble.

each to his own.
