I've copied position keyframes from an AE composition to an Excel spreadsheet, did some editing and now I'm trying to copy/paste the new data back into the composition layer. The "Paste" will not work. I'm sure it must be something simple, but I cannot come up with it. Any ideas? Thanks for your help.
You should use a plain text editor.
I forgot to mention that bezier information is not translated outside of AE. You'll end up with straight lines between points. If that's what you are seeing then that is normal. The copied keyframe data should look like the top of this exampls (invisibles showing) not like the bottom example (pasted from a word processor)
Once again, don't expect curved paths or easing to be reproduced or edited. These values do not leave AE. I don't know where they are hidden, but when the clipboard data is sent to another app all interpolation between keyframes is lost.
Using Excel to edit keyframes does work after all. Previously I tried to paste the revised data only, but one must paste the revised data and all the other information copied initially. Please see Adobe (tutorial I think) "After Effects/Editing. moving, and copying keyframes."
I did not know that Word was not a text editor.
Thanks for all the help.
