Rendering one Timeline out into 5 slices (to let me post them in to IG as a Pano)

Question

I have been trying to find a simple way to export one video timeline that's 13050x5400 into 5 1350x1080 individual videos (so they would line up)

The end goal is to plan out an Instagram post with mixed media of stills and videos into IG as 5 different videos (but as the same post, so people can slide along) I know they will all start to play at other times & I have a workaround for that.

In PS, I would have split them up into Slices, but is there a way AE can do this or am I rendering out the video and then cutting it up in PS?

Thank you in advance

I uploaded a project file. All you have to do is replace the shape layers in the Master with your original master or main comp layers. Let me know if you need an earlier version. You can change the comp size settings for the master and numbered comps. You have to maintain the same width and make the height of the Master Comp five times the height of the numbered comps.

You can import your original project or import my sample comp into your original project.

Let me know if you need an earlier version of the project file.

First, you need to follow the Complete Instagram Video Size Guide for 2023. There are several sources for this information.

Then, you need to follow the recommendations for adding multiple videos and images to a post. I'm not sure I have ever seen one that automatically slides from one image or video to the other. You will have to look up that workflow.

As far as dividing your huge video into sections that are compatible with Instagram, you'll need a separate render comp for each render that contains the original main comp and some expressions that reposition the nested comp (your original). You can use height and width and some dividers to position the original comp in each of the render comps. If the original comp is five times higher than it is wide, this expression will give you the top right corner of the original (Main) comp of your Render comps, which are named with a number. (Comp name = 1).

yOfst = height/5;
n = yOfst*thisComp.name + 1;
[thisComp.width/2, height/2 - n + yOfst];

All you would have to do is set up the first render Comp, name the comp "1", add the Main comp to Comp 1, and add this expression to the Transform/Position property. Then just duplicating the render comps in the Project Panel will give you the five comps you need to render.

That will give you five videos from a five-times as tall main comp that you can rename and upload to Instagram.
