I have the following scenario. I work with comps in After Effects, and to reduce my final render time I render these out as I finish them, to Avid DNxHD intermediates. From time to time I have to fix or change a comp, which means I have to render it out again. This works fine in premiere, as the new file is automatically reloaded. A problem however arises when I change the length of the comp. Although the footage gets replaced, Premiere for some reason still hangs on to the original clip length. When I play the clip in a media player, if has a running time of 10s for example, but in Premiere the clip is still truncated at 8s. I can;t physically extend the clip. The clip end marker is visible at 8s. I have tried deleting the clip from the project, deleting the xmp file, and reimporting. The problem still remains the same. However, when I rename the clip and import, it displays correctly. This leads me to believe that there might be meta files somewhere that premiere still references? Where can I delete these so that premiere reads the files properly like it did the first time? This adds a tiny bit of complication to my workflow, so I would like to know how to fix this. I have hundreds of comps and I render and work in parallel, so its frustrating to try and figure out which clips aren't displaying correctly, as I might only have fixed something minute.
Thanks for your post,
Please try to delete the rendered files and clean media cache of Premiere pro. Please do not render the timeline till you are using dynamic link between Premiere pro and After effects.
The simplest (best?) solution is probably just to rename the DNxHD file. You already know it works.
