I have a passion for music videos, but they are the worst. Apparently the editing is done after the 24fps films have been telecined to 29.97 NTSC. As a result, the telecine pattern shifts at nearly every scene change! Even VirtualDub's automated IVTC chokes on these. Some interlaced frames always sneak through, and the output sometimes seems to jerk or skip, as I suppose it's trying to keep A/V sync.

Still trying to find a perfect solution. wacko.gif

Many times, they seem to convert the telecined 30fps NTSC version to 25fps PAL causing some PAL frames to contain information from multiple frames of NTSC data. I hate that. Does bad things to motion detection.

I drove myself crazy trying to manually do IVTC on CareTaker Part 2. I was using the beginning part where they review what happened on the previous episode. I forget that they probably edited the 24fps film after it had been telecined. wacko.gif

There is a thread over on Doom9 started by neuron2 (Donald Graft) about doing IVTC on Star Trek clips.
