If this is obvious I apologise, late nights etc blah blah.
In Final Cut, to speed a clip up you increase the number i.e a clip at 120% is faster than its original 100%
In AfterFX you do the reverse, i.e a clip at 80% is faster than its original 100%
My question: if someone has sped a clip in FCP up to 120% , what number ( less than 100) should I remap the clip in AfterFX to to match the 120% ?

80?

^ yeah its the first choice i had but it seems to easy.

Why not use the original unaffected footage? Seems weird to speed up then slow down.
- nah, re-read that, both methods speed the original footage up. i need to match someones clip, i have source footage. they used bloody avid, i dont have avid********
- oh ok.
Sorry. I'm tired.harlequino - me too! no worries********

no. the reciprocal of 120/100 is 100/120, which simplifies to 5/6, or 83%, not 80%.

^you are right , i just did a test thing and its 83.32
weird

If you have the clip from final cut then use that if not just ask how long the final cut pro clip is then make a comp that duration and speed your clip up to fit that comp. that way it will be exactly perfect, it will probably be about 80.
- yeah there are these work arounds but was wondering if someone knew how to work it out********

really. these dudes fucked me.
shot on 30fps, they convert to 25 there, and embed their own timecode but only give me the source(30fps) footage. then give these timecodes from their fucking avid project, not form the clip timecodes and expect me to try match it.
fuckers

Well, a project I recently worked on was similar and similarly annoying.
I took the footage with a time base of 30fps, then used cinema tools to drop the timebase to 25 fps, then in a 25fps project speed it up to about 121 in final cut which would be around 80 like you guys say in AE, it's annoying I know. Not experienced this problem before or after this one time and this was the quick and dirty work around I needed to do. Hopefully there is a program which could do this instead of having to do two steps.

If you can get access to final cut I recommend you do it there before you bring it into AE if you have loads of clips that is.

^yeah its just the one, but i need to do some tracking on the footage so wanted to make sure it was perfect (for the alpha animation to match the edit). whenever you speed / slow footage in FCP, you put in 120 for eg, then u look again and its like 119,921 . which is annoying.

This might help unless you have the cunt sorted
1. make a copy of the clip and call it ORIGINAL
2. use cinema tools to make the timebase of other clip 25 frames per second.
3. import both clips into final cut
4. put them layered into a 25fps timeline
5. change the speed of the newly timebase corrected footage until it is exactly the same as the one below.
5.5. alt. put 30 fps clip on timeline, make new track mark in and out at head and tail of clip in final cut then drop new 25 fps clip over the canvas window and pick fit-fill and it will do the lath for you.
6. take that fucking frame blending crap off your footage or not depending on what look best.
Hope that helps but seems like you have you already figured out.

sweet! done, matches perfectly at 83%
cheers
