hey there,
Im a mac user currently running ASPro 5, on OSX 10.4, powerrbook G4, 133.ghz/1.25 ram.

am running some very long renders and of course, i know this is a variable result. just wanted to know if anyone else has experienced 5 to ELEVEN minute renders per frame? so slow...

You'd have to be more specific about what you're rendering.

A single vector layer shouldn't take more than a second to render, no matter how complicated. But even dozens of vector layers shouldn't be too much of a problem. But if you have bitmaps of any sort you are going to get much longer times, particularly if you have layers of them and are using masks.

So try this experiment -- just create a single shape on the default layer and render it. If it renders immediately you have no problem with your machine.

133 GHz wow that's quick! If it is 133 Mhz it is a normal render time.
One information you should provide to us to compare the render time is the image dimension. It is the most important value among the usage of particles and lots of shape effects.

rennnnnnnnnder times

whoops! Im not on my machine but its nothing unusual so Im certain its 133Mhz (not Ghz)

as for *what* im rendering, its entirely out of 1920X1080 PNG images and yes, there are indeed some blur/transparency effects applied. (sorry i neglected to mention b4)

Wow, so this is normal, eh? seems like Maya is about the same speed for outputting frames. (perhaps faster under some conditions.)
looks like this 340 frame shot will be close to a 24 hour render when its all said and done (still running as we speak)
just for the record, render times have dropped with less images in latter part of shot. they went from eleven minutes per frame, down to about three per. (thank god)

Yes it is normal. The more time consuming is the blur effect. Consider that to create a global blur you have to evaluate all the pixels of the image several times... 1980x1080x8 times (let's say that blur is a gaussian one ad take care of the eight pixels around the evaluated one) what gives more than 17 millions of pixel evaluations. Without take care of any other calculation... :)

thank you, nice to know nothings wrong.
