by "render out an After Effects Project" do you mean Render and Replace for a selected AE comp clip? If so, which format/preset another details did you select int eh R&R dialog? (screenshots help)
no, by render out i mean actually finishing off the project by exporting it to media encoder and rendering out a file. I am in After Effects and the linked sequence is refering to the sequences I made in Premiere Pro.
As far as i know, you can only render and replace an After Effects Comp in Premiere. (vise versa would be great in my case but i couldnt find a render and replace function for premiere sequences in After Effects)
By missing media, i mean the yellow screen you get when Premiere can not find your footage. It happens randomly and it seems as if dynamic link isn't working quite well in this case.
in media encoder i set the rendering settings to QuickTime H.264 codec, 50fps, 1920x1080 and it renders out in .mov. All the comps in AE and Sequences in Premiere are slalso set to these settings.
Oh I see, I missed that you were rendering form AE. This should move to the AE forum. (which I will do now)
I've had similar issues with one of my project. I've read somewhere on those forums that you need to save the AE projects and PP project before exporting via Media Encoder. It worked for me, however im not quite sure this is a solid solution.
There's some setting also in Media Encoder that might help.
Hope it helps a bit
