| Just some more notes... I'm on this project for almost two months so I have plenty of time to test! (BTW the image sequence I'm using has been edited down a little, it's now 27,000 frames at 1920x896. It represents 16GB data in image sequence form) On 23/02/2012, at 10:04 PM, Tobias Lind wrote: > I never compress the movie when rendering in AE. > Always render uncompressed or in prores to use Quicktime Pro (or Handbrake) to compress This is what I do too. Maybe I should point out that I have no trouble compressing quicktimes in general, it's not like I don't know what I'm doing. I'm just looking at all the options I have and want to find the fastest. The situation I'm in - working with a long image sequence - presents some challenges I haven't had before.

MPEG Streamclip has exactly the same problem as Quicktime Pro - it takes AGES to open the sequence, before you even begin compressing. I tried opening the sequence I have on a freshly rebooted Mac and started timing. I stopped paying attention after 15minutes, so I don't know exactly how long it took, but it was too long for my liking. I noted the other night that Quicktime Pro took about 30 minutes just to open the sequence. It's possible that MPEG Streamclip was faster, but not by much.

This is a design studio with enough Macs that it makes economic sense for them to be clever about what they install and where. I checked a few of the other freelancer Macs and they're all the same. There are full-time IT guys that are often juggling licences and plugins so I guess they only buy what they have to. At least it's all legit.

And since you can run it from the command line you can queue it as a job on your farm so that it happens as soon as the sequence is done rendering. With Lloyd's help I got ffmpeg running from the command line. It looks promising, and what I like about it is that it begins compressing instantly. However it settled down to a very steady 5fps, for a total compression time of roughly 90 minutes. A kernel panic halted my tests (nothing to do with ffmpeg) but it was obvious that the default settings I tried were only using 1 processor. I was a little dissapointed, but maybe if I did deeper and try different encoders I'll be able to get better performance. I've only scratched the surface here... Unfortunately, AE with multiprocessing turned ON is still the fastest, despite the fact that it slows down dramatically. Perhaps another option is to try rendering from AE in 5 minute chunks and then paste them together in Quicktime Pro... It takes 9 minutes to copy the 16GB sequence onto my local drive, and I've determined that having the files locally doesn't make the encoding faster - the network is not a bottleneck. I'd like to think that a modern, multi-processing aware program could compress the sequence in something approaching real-time. Next week I'll track down a Mac with Compressor on - I can try it in Final Cut too, and I'll see how Sorrenson Squeeze compares as well. -Chris |
