How to combine two videos and output as stereo 3D?

[Theojw71]

I raised a query about editing Over/Under stereoscopic video in After Effects. I'm trying a different approach - I have been able to work out how to separately generate the left eye and right eye videos as renders in MP4. This allows me to import the left eye view and edit it, then separately import the right eye view and edit that.

Challenges notwithstanding (how to be consistent in editing the two files), what do I do in After Effects to combine the left eye video and right eye video and export as a stereoscopic 3D video (not anaglyph, but over and under footage)?

There's a bunch of scripts out there that can assist arranging your comps. Was all the rage when Stereo 3D wass all the rage. Also check out AE's own Stereo effect. Can't remember, but I think it supports at least Interlaced and side-by-side. The rest of the magic happens on playback, anyway.

Thanks Mylenium. Where do I find the Stereo effect and how do I launch that? Do I need to create a new comp? Sorry,a newbie to AE still!

Effects --> Perspective --> 3D glasses. There also was a "Create Stereo comp" in the composition menu somewhere.

Mylenium, that's genius! Thanks so much - using the 3D Glasses effect settings I was able to pull in the LEFT EYE and RIGHT EYE as the left and right components and then specify the output as Over Under -  the generated lossless AVI is massive, but exactly what I was after; I can compress that back to MP4 and this unlocks my ability to deliver mind-blowing effects and animation to immersive 3D video just as I had dreamed.

Thanks so much for your time and help - exactly what these forums are for!
