Super Smooth Slow Motion from standard DV camera

[snafubaby]

I was wondering if anyone could help me out. I was working with these avs scripts and MSU Frame Rate Converter a few years ago. I recently tried to run the script with a glass of water being filled up. It looked ok, but it would momentarily stop between each frame. It wasn't a smooth filling up of the glass, and i coulda swore it was filling up in a very consistant way back when i was foolin with the script. Could anyone suggest something that would improve the timing?

Here is the script..

DirectShowSource("C:\Users\owner\Downloads\Virtual Dub-1.9.11\water.avi")
ConvertToYV12().MSU_FRC(15, "slow")


thanks for any help you can give me.

If your source has duplicate frames you will get jerky results like you describe. DirectShowSource() isn't frame accurate. If it delivers the wrong frame at some point you will get jerky results. Since it's an AVI file use AviSource() instead.

By the way, very non-linear motions like you get when filling a glass with water quickly, aren't amenable to this type of motion interpolation. Can you provide your source AVI file?

You should probably deinterlace DV before using motion interpolation
