Frame Rate converters

[Roland R. kahlenberg]

Hi Aharon, have you tried Andrew’s framerate convertor? Keeping the solution within AE should help with the non-standard assets. And there’s always Timewarp and ReVisionFX’s Twixtor.

Cheers

this is a bit of a hack way, but you might consider interpreting the footage as 24 fps, drop it in a comp and render out with a pulldown.

sure it will slow the footage by 1/25th of a second, but most films that get converted to pal are sped up by 1/24 of a second to get them to 25fps… you’re just doing the reverse.

also, it should render quickly and will preserve the integrity of each frame (no interpolated pixels).

Not a bad idea – length is not the issue here, so it makes a lot of sense.

but I need this done without fields. Any thoughts?

well, sounds like interpolation then… roland’s suggestions would work. if you use timewarp with this expression in the speed property:

(1/thisComp.frameDuration)/(1/footage(name).frameDuration)*100

it will just calculate out the rate to change the footage by to match that of the comp’s frame rate (it might work in twixtor, or others, but i only have timewarp)… of course you can do it by hand, i’m just keeping the world easy.

you could also just drop into a 29.97 comp and enable ae’s frame blending, which is easy, but there’s no control over how it interpolates new frames like there is with timewarp’s tuning options.

What about rendering the quicktime out as a image sequence, and then importing that sequence and interpreting it however you’d like?

[Aharon Rabinowitz]

you can get the same result by just going into the interpret footage dialog and conforming the frame rate – and while that’s OK for going from 25P to 24P, if you do that when going from 25 fps to 30 fps, it speeds up your footage 120% the speed.
