Without knowing your exact comp, sequence and effects settings nobody can tell you anything. just saying that it doesn't work is never a good way to ask for help.
My test documents – Premiere, AE and the original clip – can be downloaded in a 6MB zip file from this link
as I provided in the other thread I referenced.
I am guessing that you are running into cache issues. I use AE all the time for Time Remapping and shorter sequences have always worked for me when using Dynamic Link. The exception is when you are using frame blending or other techniques to improve the quality of the footage and especially when the clip is longer than 4 or 5 seconds. In that case I always render a digital intermediate to a 10 bit or better format for use in Premiere Pro or even other AE projects. I do this because temporal effects like frame blending or pixel motion take a huge amount of time to render and many times cache issues and temporal effects don't render properly through dynamic link because AE runs in the background and does not have access to as many system resources when rendering through dynamic link.
I hope this helps.
Thanks Rick. So there can be problems with linking, depending on the attributes you mentioned. Interesting.
I've experimented for several hours (and have previously done so, a few years ago), but I can't get Time Remapping to link to Premiere and retain interpolated frames. I can't even see the interpolation inside AE – unless I render. However, Time Warping will interpolate.
If anyone cares to download the zip file (only take a few seconds) and open the AE project inside, I'd be interested to find out what I am doing incorrectly.
