A way to automatically process hybrid telecined/interlaced video?

[Ranguvar]

Ripping the Linkin Park Live in Texas DVD, because I'm bored :p

The video (NTSC) appears to be hybrid telecined and interlaced. The majority of the video is telecined, and is handled nicely by Telecide(guide=1) and Decimate(). However, some scenes from certain cameras appear to be completely interlaced.

What I would like to do is either IVTC the telecined parts to 23.976p, deinterlace the interlaced parts with NNEDI+MCBob() or NNEDI+Yadifmod(), and get those parts to 23.976p by then using MVFlowFPS() or ChangeFPS(). Or, an alternative would be to get the IVTC'd parts to 29.97p by the above methods.

Err, anyways, that part isn't the point. The point is, I'm looking for a way to automatically detect what parts of the video are interlaced and what parts are telecined. Whether it's a tool that will give me the frame numbers of when the interlaced parts begin/end, or a filter that will automatically deinterlace and IVTC.

Thanks!

If it's soft telecined, the Parse D2V output will tell you which parts are in 3:2 pattern and which are not.

Unfortunately, it seems to be mostly if not completely hard telecined. Parsing the Honor Pulldown Flags D2V does not indicate any 3:2 pattern, and making a Force Film'd D2V and playing that still seems telecined.

I wonder if Tritical could perhaps add an option to TDecimate where you can specify a clip argument (with a framerate of 4/5th of the input, of course) to take frames from instead of blending when a video section is detected...

(Or something similar with Decimate, of course - it's just that TFM already has such an option for deinterlacing so the same for TDecimate would complement it nicely...)

search the forum for "NTSCtools".

should do what you want, though you'll have to read through a bit of boring stuff to know what to do.

it works similar to mvtools in that you run one function to analyse the video and make a "data" clip (well, a very small solid coloured clip in 1 of 3 colours depending on whether it's looking at 3:2, 30p or 60i), and pass that to a filter that does the work.

i used this for nearly a year doing NTSC to PAL for DVDs, and by now it's pretty solid (if i've kept the version posted here in sync with mine), but bear in mind i wrote it a pretty long time ago and so i've forgotten most of how it's guts work.
