This one is a doozy... I will give an overview of the project at hand and then my individual hiccups that are causing me grief.
Basically for my Design thesis I have an A0 composition (yes it is big) that has oh lets say about 300 to 400 layers in photoshop. I need to make a presentation and would like to include a timelapse-like video composition showing the makeup of the A0 composition from start to finish.
So, having used AE unprofessionally in the past, I know the basics and have delved into a few intricate processes, but am stunted now by my knowledge of the program and require your help. I have looked online, and have read the FAQs but have not found any answers to my satisfaction, so here goes:
I have a main comp with nested comps in it, which I am trying to pre-render in order to make the final render time shorter. Now, I have introduced my psd files into after effects having reduced their size from A0 to A2 (at 300dpi), which has already reduced the quality of the image, but not beyond unusable. The ONLY animation going on in AE is Opacity changes from 0 to 100 and a camera layer that is panning the document as all the layers come into light. That's it!
1. I read online that it is wise to pre-render in lossless so that the sub comps don't get compressed, then re compressed during the final render, lowering the overall quality of the final product. I did that... and ended up (yes i know, of course) with files 160GB thick... for 40seconds of footage. Obviously i know this is due to the extreme resolution of imagery i am using in my project (somewhere in the 7000x4000 px range) and the lossless option for output. My question, having found no other projects like this on the web, is: what would you advise me to do in order to retain a minimum of quality for my final video. I tried reducing the size of the images in AE (using the transform, constrain to height of a new HDTV 1080p comp) but that just literally scraps my images to pixelated nonsense looking stuff when the camera zooms int. I still need to zoom in with the camera at certain parts and would like the result to look prestine and clean. Any idea how i can get my A2 300dpi images looking fab in AE without having to buy terabytes of disk space? ^^
2. I am having issues with multiprocessing on my machine. I have an Asus Laptop with i7-4710HQ @2.50 GHz and 16 GB of RAM, safe to say that it is an OK machine that should give some umph to my rendering. Well, not quite. I enabled multiprocessing, gave AE permission to use 12.9 gigs of that RAM, leave 3 gigs for other programs, and allocate 1.5 gigs of RAM per background CPU, effectively utilizing 7 of the cores available. Well during my rendering, at the bottom it says AE is only using 10% of my 16gigs... and never goes higher than that. What am I doing wrong?
Many, Many thanks to whomever can help, and any information they can provide. The presentation is due soon, so I would like to get this going.
ps: I have found Dave LaRonde to be very usefull on many of other people's inquiries, Dave could you take a crack at this?
