I have 30-40 comps all exactly the same except for length which varies from 30 sec -4min, most in the 45-90sec range. Keylight, a couple of masks, render to Avid DnxHD 175 w alpha.
Rendered all day/night in one batch. Nothing else running on the workstation.
Renders times range from 1 min to 2 hrs!! Seems unrelated to length of the comp. Random render lengths, e.g.:
1hr 26 min
Does this qulaify as a bug?
HP z820 2x 12core/ 32GB RAM -25GB assigned to AE, render from/to 2 internal Hitachi deskstar 7200 HDD. Multi Proc off.
AE CC 188.8.131.52
I wouldn't call it a bug.
Besides, although the effects you use in all these comps might all be precisely the same, you didn't breathe a word whether the codec of the footage used in these comps is precisely the same... and codecs can make a big difference.
Sure, you may have rendered to the same codec. Did you START with source footage that's all the same codec? If not, you're not comparing apples to apples.
Yes, everything came from the same source in the same format. Avid DNX 220.
