Frame shift of two comps. Why???
Hi, maybe I’m just blind, but…
I have two compositions. Both have 24fps, both are 2 minutes in length. One is placed into the other.
But: When I place the timeline-thingy to, say, 1 minute in the subComp, it’s at 1:06 in the main comp. Also the values of my expression that I use in the SubComp are shifted timewise 2 frames/second. So, I lose the synchronization, and at the end of 2 minutes, I have 12 seconds difference. I did not use time remap.What can this be?
P.S.: I just tried out a copy of the SubComp, this one is perfect. Strange, strange, strange.

Thanks, Dave, for your response.
I forgot to mention, that there is no original video footage in my project. It’s an AE animation, the only thing I imported are Illustrator files. So, it’s a FullHD 1920×1080 composition in HDTV, 24 frames. I set them all up like this, but I always get confused with all these standards. I used that one that AE has as a preset in the comp-preferences. -
Well, for I’m more a designer than a technician, I’m not too familiar with each and every detail of all these things. Sorry about that. I try do do my very best to get it right. Thanks for your suggestions.
I set this project up for myself, first of all (free study project). I’m gonna burn it on BluRay later and show it as a QTmov from my computer. If I’m lucky, it’s shown on festivals in movie theaters in Germany or somewhere else in Europe. Then there will be a PAL DVD in 25 frames as a preview version. Then there will be a NTSC DVD for non European film festivals. Then there might be a BetaSP PAL tape for broadcasting. You see, I have to set something up and change it later anyways. I can’t build 3 different versions, I have to re-render it.
The 24 frames may be wrong, and I promise, my next project will be in 23.976. 🙂
If I did it wrong, I have to live with it for now or change my project carefully step by step, but actually, I did not use different frame rates in one project. I double-checked it all, it’s all set to 24.00. Anyways, which frame rate ever I use, inside the project it should be synchrone when two comps have the same frame rate, shouldn’t it?I might just switch to 25fps, then at least Europe is happy 🙂

>>My compliments on your excellent English, by the way.<<
Haha, thanks. I studied in the US for a (way too short) while.
Yep, I guess I’ll go for the 25 frames then. Oh dear.
>>If you had realistic hopes for both North America and Europe, I would have recommended a frame rate of 23.976<<
Hm, that happened before, but I’m not sure if this would happen again. I think, in case they want the film, I’ll have some fun converting it. 🙂
What I like even more than frame rates is the pixel ratio 😉 Yay, squash and stretch.
Dave, I appreciate your help. Thank you very much!
I’ll get back to work and let you know how this frame shift issue reacts to 25 frames.Best,

I now got rid of the “Auto” Framerate in the project presets to 24 (I haven’t started switching to 25 yet). Then I reboot AE and made a new composition and copy-pasted the layers in it (which I tried before), and it worked now! Cool. This might have done the trick. But with the pingpong-problem (see https://forums.creativecow.net/readpost/202/884005), unfortunately the trick did not work out. Well, I’ll keep on trying to find out a solution.
