How does Cineform deinterlace? at DVinfo.net

When importing source footage from my Sony Z1, shot at 1080/50i, and choose "deinterlace"
in the cineform import program... what kind of deinterlacing can I expect?

Adobe Premiere offers the option to deinterlace at export, but the method used seems to be to throw away one field.

We do not throw any a fields, we are better than regular field blending, but not a just as a motion tracking deinterlacer. If you shoot with a 50Hz shutter (or 60Hz for NTSC) the results are quite nice and preserve a good resolution.

What I have found is that NeoScene de-interlacing is about as good as anybody else. What makes it unique, though, is that it eliminates a conversion time. You use NeoScene to capture your footage to disk from firewire. The conversion of 60i to 24p is done during the download to disk. This is really a big plus when you are depending on having a minimized workflow.

Note, however, that files sizes are humungous. This is probably mainly because NeoScene's conversion includes a 4:2:2 color space. If you do color keying this is a nice plus. If not, it is a minus.

As with any 60i converted to 24p, it is not equal with native 24p. Closeups of subjects that are moving is where even a casual observer might notice the difference if looking for it. However, for wide shots with no closeup subject the converted 60i to 24p is usually not distinguishable without careful examination during editing.
