It's very many years since I used AE and I have now to get to grips with an old piece of work and render it 'better' and in HD. I am constrained to the same sound track and just have to enhance it and upgrade the animations . I use Premiere Pro a lot ... but I'm rusty in AE .
The goal is that the finished work will have very good HD clarity.
So three questions have arisen:
1. On rendering 'best and lossless' files out of AE (to check my animation) I'm getting jerky footage from the 10 seconds of uncompressed rendering. Can I expect to get uncompressed HD or will I have to use a codec and so which one for best quality? The resulting files are just for me to see (mostly) but also be shown publicly on 10ft by 10 ft screens.
2. I am wondering if a good workflow for this reconstruction would be to make the short animated clips in AE and render them as Premiere Pro projects for compositing in Premiere? I haven't done this before but suppose it will be easy/OK? Will that route ensure good resolution by not rendering out the clips first from AE to import into Premiere and then rendering again for the final output from Premiere Am I right, is this a usual workflow?
3. For making 5 minutes of HD compositing and rendering I think I have too little RAM with only 12Gb on board. I am going to increase it to 32 ... is that enough or will it have to be 64Gb? Plus to render HD, do I need a hard drive reading and writing faster than 450?
I hope one of you can help me make some progress.
Thanks a lot
Too many uncertainties. Upscaling depends completely on your source material. I've pre-comped final projects in the desired resolution and scaled them up by hitting.
And by marking the checkbox "continues restarization" to on. I think it also can be done by just changing the render settings, but you would lack a good preview. Also color profile and bit-depth might need some alteration.
Any lossles huffman based codec will do the job. Lossles RLE compression will not always guarantee speeding up rendering and playback. I like to use image sequences for multiple reasons and always suggest it. Besides that I also like to use the Premiere dynamic link feature. And in the early days i did a lot of offline editing.
Image manipulation works frame by frame, there's no rush to give a realtime stream. AE works like an automated Photoshop. It loads the frame into the memory, manipulates the image with a set of rules it has been given and spits out the answer.
The more instructions it has to do before it writes down the final answer, the larger the memory that is needed. Thats why breaking down the project in multiple render passes allows you to do more complex manipulation, with limited memory and often it allows for multiprocessing.
A Full HD frame isn't that shocking
1920 x 1080 x 32bits x 4 channels / (8 bytes x 1000^2) = 33 MB
Having bulk of memory is practical for realtime viewing and faster rendering, but not a "must have" to finish the job.
