I have some files using VC-1 interlaced.
The content is actually 25fps progressive content telecined at 29.97fps.
The current deinterlacer (at best setting) produces a frame sequence where every sixth frames is a copy of the fifth. This produces a good picture, but also introduce motion jitter. It's especially noticeable in panning scenes.
A detelecine filter would improve picture quality by reconstructing the original progressive frames. No motion jitter is present, the output is at the original 25fps.
A second possiblity is to use a Bob deinterlacer, giving each field its own frame in the output file. The quality is less, but the intended timing is maintained, reducing motion jitter.
