You can use AVISynth to IVTC the 3:2 pulldown 29.97fps back to the original frame rate, or at least the original frame rate when telecined. The true original is 24fps.
Ok… there is a misunderstanding here of some form. I’m confused as to what you both mean. I certainly understand that I can use AVISynth to IVTC a 3:2 pulldown 29.97fps back to 24fps. But I am not working with 29.97 content per say.
I guess where I’m at is - I’m capturing at 60fps because the content is natively 480i/60 (60 being the field rate, not the frame rate). I understand the frame rate of the movie was originally 24fps on film and then 29.97fps on the disc, but the field rate of the image is what I am concerned with, the LD content is displayed at 60Hz.
The disc is playing at 29.97fps, but that image is flickering at 60hz. I’m capturing the entire flicker by capturing at 60fps, then post-processing to remove flicker/interlace. I understand that functionally what I am left with is a frankenstined 30fps content with the frames more or less doubled and being played back at 60fps. However, I have found that because of the 60Hz rate that this was originally outputted from the LD player at, that this leaves me with a much better image. It seems to me that this has prevented a great deal of the “smear” effect people describe in LD captures.
I understand there a numerous different ways to work with analog interlaced signal, I am not understanding what benefit would be derived from taking this content back down to 24fps - 60 is to ensure the image remains as smooth as possible.
If I’m misunderstanding what you’re suggesting please explain why - I do want to offer the highest quality image possible.
