Convert 480i60 -> 240p60? (In other words, I want to see the fields)

[Colmino]

So I have this clip of DV video at 720x480, 30fps interlaced. I'm trying to figure out what went wrong with the capture process, and in order to further my investigation, I have got to figure out a way of forcing Premiere Pro (or VirtualDub, or something) to show me the two fields which they are using to generate the progressive frames being shown in the preview boxes. Ideally, what I would like to end up with is images of the fields as either 720x480 frames which are one big comb from top to bottom (a line of video, a line of black, a line of video, etc.) or at least the individual 720x240 fields themselves.

It's pretty amazing that neither of these two otherwise very useful applications give the user any option of seeing their video without any processing.

Hi-

Best would be an AviSynth script opened in VDub:

SeparateFields()#for 720x240 at 59.94fps

or:

Bob()#for 720x480 fields at 59.94fps

or:

LeakKernelBob(Order=0)#for a much better quality "Smart" Bob

You can do similar things in VDub. For the 720x240 fields, Go Video->Filters->Add->Deinterlace->Unfold Fields Side-by-side. You can play around with the other options and get other things.

Thanks. Ironically I found the VDub process when I read a description of a filter which does the same thing except for generating the two fields one atop the other. ;p
