If you are asking about placing an AEP file into Animate the answer is no.
You need to export out of AE a file format recognized by Animate. Then to do the Animate to Muse move, you need to publish the OAM file from Animate and then place it into Muse. i walk through the Animate to Muse workflow in these two vids on YouTube : Animate Video to Adobe Muse Workflow: Part 1 - YouTube and Animate Video to Adobe Muse Workflow: Part 2 - YouTube. Though I use an mp4 video (which could be created by AE) the key is the OAM file.
Thank you for the quick response!
Do you happen to know the different file formats Animate accepts? I tried PNG sequences but they don't seem to work.
I'll definitely take a look at your videos.
if you need transparency then png sequence is the way to go. If it doesn't need transparency then jpg sequences are are a good choice. To really keep the file size down you might want to also look at GIF animations. I usually shoot the jpg or png sequence into Photoshop and use the timeline to create the animated gif . if you want the full video experience then output an mp4 from AE and drop it into Animate but turn off the controls if it is just an animated sequence. for motion in Animate: mp4, webm and Animated Gif are the choices.
If you do need to run a jpg or png sequence out of AE then use the Region Of Interest tool in the comp to trim off the excess. Then output the sequence and drop the images into an Animate Symbol.
