What model SSDs are they?
How long are the videos you inserted in the project?
The SSD is a Corsair Force GS 250GB
The videos vary from 3 to 20 seconds.
Hmm, I haven't considered how long the slots in the template actually last.
Did the render actually take 35 hours or did you not let the render finish?
That's NOT a reasonable time. I recommend purging memory & caches before rendering.
If that doesn't help, I'd cast an eye on your video footage. mp4 can be very computationally-intensive. I'd try transcoding to a good intermediate format like quicktime movies in Photo JPEG, PNG or Animation codecs.
And another thing -- the youtube thingy I saw used still images. You're using video. AE has a lot less thinking to do with still images than with video, so that could be the root of the problem.
I let it finish.
I transcoded to Photo JPEG and Video UT (to try it out). Times dropped to 20 hours (I didn't let it finish this time).
I think I have just picked the wrong template for use with video. I'll keep playing around to see what works best.
What did you end up doing to solve this issue? Did you end up exporting this template? Let us know what you did and if you can provide any advice to others, that would be great.
