.MOV file (8fps) -> VCD - Recommendations?

[magwell]

I have a .MOV file which runs at 8.019fps and would like to convert it to VCD. I've tried various methods using Virtualdub and TMPGEnc without much success. Playback is extremely choppy, which I expected.

Can anyone recommend a procedure/software which would give me the smoothest playback possible? Sound is NOT an issue here, so no worries about sync or audio speed-up. I just need the picture to play as smooth as possible without video speed ups. Or am I asking the impossible?

I may be completly wrong as to if this would work but i don't have any 8fps videos to test this on.

My idea is to apply 3:2 pulldown to it which should convert it to 10fps. My logic is that if you take a 24fps/23.976fps you will get a 30fps/29.97fps video then if you do the math and use the same 3:2 pulldown process to an 8 fps movie you should get a 10fps video(8/x=24/30, x=10).

Then converting a 10fps video to an NTSC 30fps video should be smooth because all you have to do is triple every frame.

I'm not sure if this would work at all but another problem i could see that would happen is that when you apply 3:2 pulldown you are in fact interlacing the video and you wouldn't be able to encode a VCD because MPEG-1 doesn't support interlacing. So you would have to create an MPEG-2 based video(i.e. SVCD,DVD).

I don't know if this would work but someone please correct me if i'm wrong in anyway, or you can give it a try and see if it works.

Last night i was thinking about this and I figured out a better way. if it's 8fps(probably have to slow down the video) you can just triple every frame and have a NTSCfilm vcd playing at 24fps. That would be so much easier than doing a 3:2 pulldown first and you could make a vcd. I don't know why I thought of the other way first. I usually end up thinking of a complicated solution to a problem and look over the simpler way of doing it.

No matter what you do, it's still 8 fps. Trippling it to 24 fps is going to look exactly like the original 8 fps. There are only 8 different frames per second. If it's interlaced (don't know about MOV's) there are some options with the fields, but the best you could hope for would be 16 fps.
