Hey guys.
I'm finally trying to get a working IVTC Script so I can get back the original 24fps material. But my captures have some very odd ways of showing the frames so let me show you.
I ran a sample through VirtualDub (frame by frame) and this is what I came up with for roughly 2 seconds of material taken from a prime-time show on tv.
3 Progressive
2 Interlaced

1 Duplicated

2 Interlaced
The progressive/duplicated/interlaced frames aren't exactly in a certain order. It appears that they go quite randomly.
Is there any kind of AVISynth Script that I can use to handle the IVTC for this?
I can even send the sample AVI somewhere if needed.
It's a 640x480 NTSC AVI file that was captured using the Huffyuv Codec.
I'm really baffled so ANY help is soooooo appreciated.
Thanks |

Are you sure the source is film? You mentioned that it's a primetime TV show. Sounds like it may be video, if so de-interlace it. If you are sure it is film then you might want to try the telecide and decimate functions in AVI-Synth. |

Telecide should handle it nicely with:
| CODE | telecide(guide=1)
decimate(cycle=5) |
Ignoring the duplicates, your 2 interlaced frames are 5 frames apart throughout the sequence you posted, which is certainly indicative of a film to NTSC transfer. The duplicates could be part of the program material (that's normal), or they could be dropped frames (that's bad).

May the FOURCC be with you... |
