MacTel CS3 Problems.
-
Hey All,
I tried doing that. I tried, 23.98fps, comps and interp. I tried straight 24pfs, and I tried 23.976fps. On each one I interpreted as the frame rate and made all the comps that frame rate. All did the same thing.
BTW, I don’t have this problem in 6.5, I tested that yesterday. Only in CS3 8.0.2
I thought it might be a codec thing, but I tried it on 3 codecs so far.
I think its a BUG, its doing a pulldown thing for no reason. Don’t want to spend all day figuring out Adobe’s mistakes, so right now I am trying to find a work around. But wish I knew what the heck was going on…

let’s go back… the files you are having a problem with were rendered from ae6.5 at 23.98. were those purely animation, or did they have footage?
if they were purely animation, can you go back and set those comps to 23.976 and render them as 23.976 progressive? then take a look at those in cs3, making sure the footage is interpreted as 23.976, no pulldown/separate fields and the comp frame rate matches the new footage.
if you had footage in the ae6.5 comp, then make sure that that footage is correctly interpreted (i’ll assume it is 24p, no pulldown) 23.976 and no separate fields/pulldown. then make sure the comp is set to 23.976 and render as 23.976 no fields/puldown. take that to cs3, making sure the footage is interpreted correctly and the comp has the same frame rate and see if you see a problem.
if you still see a problem, then i guess there is a cs3 bug, but i haven’t seen it…. yet.

But can’t you only render to 23.98 from After Effects? In my quicktime settings for video output the defacto standard is 23.98. I can do custom settings I suppose. When I get a free sec I will try that..

23.98 is actually 23.976 fps… you should render as 23.976 out of ae to go into, say, a 23.98 fcp timeline.
i’m not a fcp expert, so you may want to double check that in the fcp forum, but it’s the workflow i’ve always heard described…

yeah, this is a problem for After Effects, not having any problems with Final Cut Pro, don’t know why I would need to check the files in Final Cut Pro??

You can render to any frame rate you want =O Specify the frame rate of the rendered file in the Render Settings, generally you’d want to leave it on “Use Comp’s Frame Rate.”

you wouldn’t need to check the files in fcp, but if the footage came from fcp, it is 23.976fps, even though fcp calls it 23.98fps. so in ae you should interpret it as 23.976 and use comps with the frame rate of 23.976…
if you were taking your effect footage back to fcp (or any software to use as 24p), you would also render it as 23.976, not 23.98.
by not keeping a consistent framerate, you may be getting duplicate frames…
that’s all i was trying to say.

I know that you can import into FCP and and I know that FCP is 23.98. I also know that you can render 23.976 from the Quicktime settings. What I am trying to do is find the bug in my after effects.
My comment about 23.976 out of AE was that if I have to do it every time I render. Its kinda a hassle. I should be able to do everything at 23.98 across the board. From 3D to Film. From 2k Cineon film scans to pixel vision, from Discreet Smoke online to FCP. Doing a workflow that is 23.976 in After Effects kinda blows.

what i’m trying to say is that 23.98 is in name only, it is not the actual frame rate of the footage. the actual frame rate is 23.976 fps.
kind of like in construction a 2×4 isn’t actually 2 inches by 4 inches, it’s 1.5″ x 3.5″ but they call it a two-by-four anyway.
for some reason apple decided to call the ntsc 24p frame rate 23.98 rather than the actual 23.976…
the 24p frame rate in ntsc is 23.976, the math won’t work otherwise, and you will get either dropped frames or duplicate frames if you use other frame rates. if you work with 24p footage, you need to work in 23.976. fcp and other apple products just call it 23.98, but they mean 23.976, and they need it to be 23.976. and i’m thinking more and more that this at least part of your problem.

Indeed.
4/5 of 30fps = 24 fps
4/5 of 29.97fps = 23.976 fps exactly.Unlike FCP, AE cares very much about 23.976, and requires that we work in that exact frame rate.
