Interlaced frames checker?

[kcb]

Is there any program out there where i can check if an svcd video has interlaced frames, how many and at what location?

[kcb]

specifically, i want something that works with IVTC'ed svcd's. Sometimes when the ivtc is done i have artifacts that remain (sometimes i miss them) i want to grab the location and the number of interlaced frames found so i can correct them.

Hi-

Decomb comes with an "IsCombed" utility that is supposed to do that. I've never used it myself, but it seems to be able to do what you want. Quoting from the DecombReferenceManual:
IsCombed(parameter_list)
This utility filter is designed for use within ConditionalFilter(). It returns a boolean to indicate whether a frame is combed (interlaced).
threshold (0-255, default 20) sets the amount of combing required to declare a frame combed. It is analogous to the threshold parameter of FieldDeinterlace(). You may have to tweak this for best performance with your specific material.
If you're handy with AviSynth, you should be able to figure it out. If not, then ask neuron2 in the AviSynth Forum.
