Exporting/rendering composition with AME taking 8 hours.
Hello everybody,
I’m slowly getting sick of rendering compositions (720p), trying many different settings and everytime getting stuck with rendertimes of 6-8 hours for a five miinute video. I chose the H.264 codec and it outputs to an about 250 MB in size MP4 file. I honestly do not know how to solve this, but I do know that I want to cut the rendertimes by at least a half, to 3 or 4 hours.
Please, please help me.Best regards,

5 minutes is a pretty long AE comp so it’s hard to say whether you’re render times are truly excessive without more details. That said, things you can do to reduce render times:
- turn off OpenGL
- add more RAM to the machine if it’s not already maxed out
- pre-render as much as possible (nested comps, etc.)
- make sure all sources are on a fast hard drive or RAID
- read sources from and write renders to separate drives
- close unnecessary programs and background processes to dedicate RAM & processor power to AE
- check AE’s “Improve Performance” page in the online help for more tips:

Never ever render straight to H.264 (or any other compressed format for that matter) directly from AE.
Render to an uncompressed format, animation codec, or ideally a tiff/png sequence. Then use Adobe media encoder, appple compressor, sorenson or another program to encode to H.264 using multipass.
Ae can only use a single pass when encoding, so does a very bad job of making interframe compression formats.
Also depending on your particular computer setup (which we know nothing about) encoding h.264 at the same time as a render can slow you down.
