Thanks for the heads up :)
I did see that post before so I'm wanting to keep the same playback speed.
The problem I'm having is that I can't stand the ghosting/blended frames that many guides deliver and it doesn't help that the source is interlaced. Yadif gave jaggy edges and so did TDeint but not as bad as yadif and both lose too much detail where there is low ligjht.
CCE's deinterlacer is smooth and detail is good but too soft.
Finally I discovered TDeint's mode 2 parameter which is amazingly smooth, sharp and has great detail by combining detail from 2 frames via bobbing somehow. I'm also testing its "tryMesh" parameter.
But bottom line is that the end result will have the same running time via ChangeFPS(23.976) and a pulldown. Dropping frames is better than ConvertFPS's ghosts, methinks. I did get feedback on a clip from a couple of guys, including JD, and playback is fine without jerkiness as far as they're concerned :)
However, I really wish there was a filter that would add 2 frames and delete 3 frames instead of just deleting a frame, which is how ChangeFPS works in this case. Of course, the 2 added frames would blend the usually deleted frame with it's adjacent frames and all 3 of those original frames would get deleted.
Actually, is there such a filter?
