I recently purchased a DVD set of a US show that was only released abroad (go figure!). The series was clearly shot on film as far as I can tell, but the DVDs are in PAL format. I am thinking of trying out IVTC, but since its technically in PAL format but was telecined to NTSC, do I need to convert back to NTSC or is there a better and more accurate route?
Thanks

It is definitely interlaced. I have some sample NTSC DVD copies and I played with the IVTC and I am pretty sure between that and the appearance of film grain that it was shot on film. Wasn't sure if there was a fix I could do in a batch as there are almost 100 videos I need to process.

There are several options here:
1: it was shot at 24p, then pulldown was applied to convert it to 25i
2: it was shot at 24p, then it was blend converted to 25i
3: it was shot at 29.97i...
Actually it just blows out from there, maybe you should just post a sample for us to look at. -
It was shot at 24p (23.976...), pulldown to 29.97i, converted to 25i. I am looking to bring it back to the original framerate.

Then how about a sample, as ndjamena has already requested? If what you say is correct (and I doubt it is), you had better learn some AviSynth, and fast. 10 seconds of steady movement from the source (not converted to anything else) should be plenty.

The most common solution for film at 30i to 25i is a smart bob followed by SRestore.

Sample attached. Maybe I am looking at this wrong, but the show was produced in the US and I have the impression it was done on film, though I have not looked at the frame order to verify.
Thanks for the help! -
That video has been totally destroyed. Throw it out. If you really must use it, leave it like it is.

I stuck it through Handbrake just for upload. Are you talking about the frame rate conversion or the PQ?
The show was released in the US, but the complete series was only released abroad. There were individual releases here with five episodes missing. The complete series is on iTunes but they fudged the PQ and deinterlacing to an unacceptable point.
I have attached a sample from the same episode from the NTSC release encoded @ CRF 22 for upload. -
The video (in post #10) was resized as if it was progressive but it contains interlaced frames. It's also encoded progressive to further screw it up. Upload an sample that has not been reencoded. Then we'll see if Handbrake cause those problems or if they're in the source video.

If you re-encode, we can't help. You must use a tool which simply cuts, but leaves all the pixels intact. You only need to upload 5-10 seconds of video, but it needs to contain lots of motion.

The PAL video in post #19 can be mostly restored to the original film frames with AviSynth:
Code:Mpeg2Source("filename.d2v") Yadif(mode=1) SRestore()
Code:Mpeg2Source("filename.d2v") TFM() TDecimate()
