sorry didn't saw "comp"
but you can stretch.

from 25 to 29.97 it is 83.42%

if you don't need sound, interpret as 29,97 .
=
it will speed up but image will remain perfect

Sorry to sound like a pedant but that's = not PAL or NTSC. =A0Those terms refer to the old analogue system. =A0Incide= ntally, analogue TV has just stopped broadcasting here in Australia so I su= ppose it's no longer correct to refer to us as a PAL country. =A0Using = the digital terminology, PAL is (was) 720x576, 50i and NTSC is 720x486,59.9= 4i.

You have HD comps. =A0There is no PAL or NTSC with high def, just different= frame sizes, frames rates, and either progressive or interlaced.

You've said that you have a 1920x1080 "PAL" comp - does that = mean it's 25p or 50i? =A0And you want it to be NTSC - again, you actual= ly have a few frame rates to choose from - 29.97 and 30 progressive, and 59= .94 or 60 for interlaced.

The easiest way to do it is just import the clip into After Effects and ens= ure it is interpreted correctly (frame rate and fields). =A0Then drop it in= to a new composition that has the new settings you want (e.g. 1920x1080, 29= .97). =A0After Effects will take care of the conversion and you just have t= o render it out.

This probably won't give you the best results though. =A0The next step = is to turn on frame blending. =A0Try both settings and see if the pixel-mot= ion setting works without artefacts. =A0If that doesn't work too well t= hen split the clip at each edit point, and use the time warp effect - adjus= ting the parameters for each clip. =A0And finally, if that doesn't work= too well then try a 3rd party product like twixtor. =A0Don't expect Tw= ixtor to do a better job that After Effects without you doing some manual a= djusting for each shot though.

You might have to split the clip at each edit point and use a different tec= hnique for each shot. =A0If you can get pixel blending to work then great, = but often there's a rogue scene that won't work with it. =A0Try it = and see...
