Because this is the finale of the Mole, they incorporated a "live" portion to
the show, similar to Survivor where they talk to the contestants and look back
at moments during the season. Normally the show is shot at 24p, however the
live portion of this show was shot at 60i. This combined with footage from
previous shows shot at 24p created a hybrid source. We did a test performing
an IVTC, however anything that was shot at 60i was too jerky. So instead we
just deinterlaced the source. The portions that were shot in 24p don't look
as fluid as they should however it looks much better than the 60i footage
IVTC'd to 24p.
So if you do happen to go frame by frame though this you will notice that some
parts will have dupe frames and some will not.
Check the sample for an example of native 60i ivtc'd to 24p.
