progressively longer renders
I’m doing 43 identical renders (just minor changes on each one) for a local CW network affiliate. They’re HD scaled down to SD. They SHOULD take around 15-20 minutes apiece. Oddly, the first took 40 minutes, the 2nd took 1 hour, 3rd 1.5 hours, 3rd 2.2 hours, 4th 3 hours, 5th 3.8 hours and 6th over 4 hours. The keep taking progressively longer (I stopped it after the 6th render). Does anyone have any insight as to why this would be happening?
Running CS3 on a dual G5.
thank you,

Thanks for responding Dave… Yes, I’m using HD movies; and I can see where it would take longer. I just don’t know why each SUBSEQUENT render takes exponentially longer than the previous one (even though they’re all basically identical).

Dave,
Thanks again… And it is the same Kurt from the same Buffalo (thanks for the vote of confidence!). I didn’t know that about the codecs (so much for knowing my stuff). When I get info on them, they say Apple Animation (I’m assuming the Animation+ codec because they contain an alpha). When i look at the Render Details it says ‘Preparing’ for stretches at a time, which leaves me to believe that you are correct (I’ve never seen that before). The production house that created these easily could have used AE’s text instead of these massive 3D movies – you barely notice that they’re 3D anyway….
Again, thanks Dave.

Sorry to bump in on the conversation, but I have something I’d like to ask about the choice of codecs.
If I am creating my ae render in pieces, rendering out each piece so that it is easier to preview, which codec would you reccomend for HD?
Animation does not seem to give any better file size than uncompressed, and it introduces noise.
I was a huge fan of huffyuv, but it is now old and does not decompress fast, which means long render times.
DV was an easy format to export to with SD because of the quick decompress and hardware assist as well as low generational decay (canopus)
I’ve heard good things about cineform, is this what I’m looking for?
I just cannot seem to find a good full frame lossless codec which decompresses faster than uncompressed for 720p hd.
Thank you

well it is a big nested composition. I would like to render green screen elements so they are easier to manipulate.
Not preview part of the project.
So a quick decoding lossless ((I meant dv is lossy but it’s only as good as the source…) codec which is better than uncompressed processor wise.
I have an older computer.
The studio has a dual quad core xeon
I have a dual xeon from 2003 at home 🙁
