Crazy rendering time.
Hello all,
Just after a bit of advise here. Im creating an MPEG2 file using Media Encoder dynamically linked to After Effects, the original files are about 45 minutes of .MTS files and 3 animations i created. The MPEG2 is pretty much a preset except for i changed the quality from 4 to 5. So far it has going since 6:30am GMT (about 9 hours) and its only half way done. My computer should be up to the task so I’m pretty sure it can’t be that:
iMac 27″
Processor 3.4 GHz Intel Core i7
Memory 32 GB 1333 MHz DDR3
Graphics AMD Radeon HD 6970M 2048 MBShould i cut my losses, start again but play around with the bit rate? Or just wait it out? The MPEG2 was estimated at about 2.8 gig.
Any advice/suggestions are greatly appreciated.

Dynamic link doesn’t use Ae’s multiprocessing feature, so it can’t exploit all your system resources to speed up renders. If you have multiprocessing on, you’ll get faster results in most cases rendering from Ae to an intermediate file, then compressing that to MPEG2 in Media Encoder.

You can also render from AE- I get very good MPEG2 results.
4 should be good enough- no need for 5.Tudor “Ted” Jelescu

Thanks for the reply. Sorry could you explain what you mean by an ‘intermediate file’. Then Ill give that a go.

Thanks for the advice! Im not sure why i always upped it from 4 to 5 i just always without thinking about it. I used to render straight from AE however the results were always horrible for me. Thinking about it i never actually burned the MPEG2’s to DVD to see how it played on a player/tv, surely it would be better on a DVD player than my computer? I just saw a horribly artefacty grainy mess and deleted. Perhaps this was a mistake?

I mean render from Ae to a mastering-quality file. You could use the Lossless preset in Ae (though this will give you a pretty big file), or use a lightly-compressing codec like Apple ProRes, Avid DNxHD, or GoPro CineForm. Take this file into Media Encoder for additional compression.

Again thank you for the swift reply! I will most certainly try this, sounds like a great idea.

For MPEG-2 and H.264, I recommend using Adobe Media Encoder (AME) for output, not After Effects. AME does a better job for these formats.

Todd does your suggestion apply to both QuickTime H.264 and MP4 H.264?

My suggestion wasn’t related to QuickTime H.264—but I would also recommend against using that format unless you have a very good reason for doing so.
