VIDEO GOGH SLOW SLOW SLOW!!
on May 17, 2005 at 4:15:30 am

Just wanted to ask if it is common for video gogh to work incredibly slow?? (76 hours rendering for 1 min??)
I have a fast pc and have never experienced such pain till the moment i used video gogh!!!!
Whats with this product?? I had applied video gogh to 5 layers (with default settings) and it was murdering my after effects.. its a pitty it works so poorly because the results look great once the epic rendering is finished..

Hmm. Not sure what's going on
but for me VideoGogh renders
in about 30~50 times real-time, meaning
60sec of footage would take something
like 1800-3000 seconds. This is on
AE/C* w/ PC/Mac, NTSC D1 frame size/
rate.

Or, did you mean there's an instance
of VG for every layer? Have you tried
rendering intermediates, then apply
VG?
Are you using the latest version: 2.7

BTW: if "Render Current Over Last" is
checked, you'd get unpredictable results
if you submit the job to multiple nodes.

76 hours is 273600 seconds. That's 152 seconds a frame (at 30 frames a second).

I just ran a test where I had 5 layers of 720x480 sized images, brush size of 0.1, and it took me 28 seconds a frame or so on a dual processor machine. That would be 50 seconds or so on a single processor machine. I also noticed that the longer the sequence went on the longer it took to render a frame because brushes tend to accumulate.


The reason it takes so long is because Video Gogh is doing *lots* of work. It tracks each pixel and then renders thousands (possible hundreds of thousands) of brushes.

Not sure if 152 seconds is "normal" or not. It's certainly not out of the range of possiblities. For example, the length of time per frame greatly depends on the brush size and size of the image. However, you might want to your image cache preferences for AE. I'm wondering if you are thrashing to disk. Perhaps you should try setting AE's image memory cache to something less than the default. Perhaps something like 60%. The less memory you have, the more it is possible you are thrashing to disk).

It would be helpful to know how much memory you have, what brush size you are using and the resolution of the images.

I'm running 2 gigs ram with dual processors...

I have 72 layers in the comp with a ton of effects.. so i can understand that it would take a long time
to render. Its pitty though... I've had to remove the video gogh effect from my layers... I might use it for another less intensive project.

thanks

Marco.
