Question

so, when I try exporting my file in h.264 format (mp4) I get an error message when I start the cue, i get this message: adobe media encoder failed to encode with the following exception: App.getscriptenginename is not a function

please help I need to export a video with a transparent background so I can't just screen record it anymore

(in the future, on adobe.com ae = after effects. use ame for media encoder)

i googled that exact error and google could find no matches. that makes me wonder if you have an ame or animate problem.

to test. create another simple animate animation (just a few frames with one object) and export video to ame. see if you get the same error.

Got this same error but aparently for another reason. After a sucessfull export, if I try to do it again but leaving the filename unchanged (eg. exported.mp4) my media encoder crashes. Have to either delete the previous file or set a different name before exporting.
