Looking for some hybrid interlaced/progressive content.

So, I'm in need of some content that contains both interlaced and progressive frames in the same file. Anyone know of anything off the top of their head?

It should be easy to find both, progressive and interlaced, footage. So you can easily create the desired kind of sample by merging/interleaving ;)

Use AviSynth. You can create sample clips in any variation (resolution, fps, duration, interlacedTFF/interlacedBFF/progressive, etc.
