2 Minute video taking 5-7 hours to render???

I had a 1 minute 53 second minute Fortnite montage that I was exporting, and I saw that the time was 4 hours.  I left it going until that night, as I was going out of the house anyway.  7 hours later, it finished.  The video is good quality, and everything is working fine, but the I think the render time was ridiculous. Hopefully someone can help me reduce the render time for a future export.  Here's more information about it:

I used Dynamic Link and did the "Replace with After Effects Composition" thing on a black color matte.  Then I edited it in After Effects with 4 3D cameras to track text, RSMB, Magic Bullet Looks, a bit of Time Remapping, Mirror Edges, and S_Shake.  I closed AE, waited for Dynamic Link to get everything into Premiere(which took maybe 1-2 minutes), and exported it.  My sequence settings are 2560 x 1080 (21:9) at 60 frames per second. Pixel aspect ratio is D1/DV NTSC (0.91).  Export settings are H.264 with a custom preset (the only thing I changed was turning on Use Previews because I saw that in a YouTube video).  Time Interpolation set to Frame Sampling, and the estimated file size was 139 MB.

Computer Specs:

Macbook Pro 2015

8 GB of RAM

256 GB SSD(Internal)

2.7 GHz Intel Core i5 Processor, 7th Gen

Intel Iris Graphics 6100

Correct answer Averdahl

Use square pixels (1.0) instead of 0.91.

One way to work around issues like yours is to render out parts and then combine them together. For example, render out the first ten seconds, then the next ten seconds, etc, etc til the end. It usually works but it requires that one are careful when defining the Work Area in After Effects to avoid frame duplicates. Use a good codec such as CineForm or ProRes.

Yes, it´s a pain but it usually is the last resort to issues like this. The mix of the effects you use are indeed render hogs.

All the effects you are using are resource hungry and your computer has fairly low specs. You will save time if you render out directly from Ae. Dynamic Link is by unfortunately nature slow.

BTW, why do you use the D1/DV NTSC (0.91) pixel aspect ratio?

Ok, that's what I was thinking might be the case.  But the problem is I can't render this out directly from AE, as it keeps crashing.  I'm not running out of RAM or disk space, but the render always crashes halfway through.  I could try it again later today and give you more details.

I've got no idea why I used the 0.91 pixel aspect ratio, I usually use just square pixels but something happened and it was set to 0.91 when I last checked.
