Render animation time

I have a simplistic model (4 parts, 10 or so screws) that I am trying to render an animation through using Studio with the lowest possible output settings, my concern is that the render time is extraordinary long even for the most basic of assembly, why is this ? I have also tried the animate when in an IPN file which does improve render time but the quality is not very good. I will now try using keyframe animation in Showcase to see if I can get an animation with good quality completed within the hour ! Has anyone else experience these VERY poor render times for basic animations or am I missing something here ?

System specs?

Length of animation?

Post assembly here so others can test.

system specs -

processor - Intel(R) Core(TM) i7 CPU 920@2.67GHz

RAM - 12GB

Windows 7 (64 bit)

length of animation is 40 seconds. it is a fly by of a 4 pump water pumping station.

i cannot upload the assembly due to work regulations.

What version of Inventor?
Have you installed all service packs?

Graphics card specs?

How about this Update (I haven't read what it actually covers -might not be anything for Studio).

Inventor 2013 64-BIt Edition SP1 Beta

HP Z400 3.07GHz, 12GB RAM

ATI FirePro V4800(FireGL)

 

I have checked this spec out with our IT company and through posts on the internet , this spec meets and more than exceeds the requirements of Inventor however the render time is still chronically slow, is this a problem with IV itself, I cannot wait 2 days for a simple render animation

I have now tried to render a 10 second video in Showcase with the Ray Tracing visual style set and this is taking an painful amount of time (35% completed - Elapsed time = 10 minutes), can anyone advise on how to improve this ?

Are you rendering at 30 frames per second?  ~6 seconds per frame sounds excellent to me, especially with ray tracing enabled.  Of course, even though you only have 4 parts + 10 screws, the complexity of the parts could have a huge impact on render time.  If any features are too small to show up in the rendered video, making a simplified version of the part will improve your render time.

 

If you open up task manager during the render, how much of your ram and cpu is getting utilized?

Hi, I think it was set at about 5 frames per second but even with this low value it's grinds and grinds to the point where I just cancel it. I can't believe such a simple assembly animation can be such a problem in Showcase, I have tried rendering animation with ALL the lowest settings and it's really really slow. I've seen many posts on this subject regarding similar issues. I will check CPU ram during render and get back to you. Cheers

Without the files - not sure how the problem can be solved.

Even with the files it might be difficult to solve if it is a hardware setup problem.

 

The only thing I can think of is a comparable test on identical dataset.

If I go through the Help>Tutorials Studio Tutorial and test the Render time - can you do the same?

I just ran a test on my laptop using the Tutorial dataset (Arbor Press) with the actions indicated in the tutorial.

I set a 300x500 for the size 15 frames per second for 3 seconds.  Highest anti-alias, full frame (no compression) avi file.

On battery power took 16 minutes.

On power supply took about 11 minutes.

 

Seemed pretty normal time to me for rendering an animation.

To Improve rendering time there are many things to check:

  • Make sure you remove all objects in the scene that are not visible when rendering.
  • What settings do you have set for you movie format? Have you tried different codecs?
Message 18 of 21

Hello. Thanks for your reply. I only have the model I have imported from IV 2013 visible, I am using a Hdr image as a backdrop to the scene. I am not sure how to try different codecs as you have suggested but the settings I am using for rendering are save as: MPEG-4 movie(MP4), preset sizes:800x600, Frames per second:25, Anti-aliasing:Low. With these settings I do get quite a reasonable render rate, however the problem occurs when I try to output with these setting with ray trace included, it grinds to a halt and crashes.

See if the same thing happens if you save as AVI. Also do the same test with the different scene. I could be that the graphics is bottoming out.

 

Message 20 of 21

Hello. I have left a video rendering overnight with the above settings - took nearly 4 hours to render a 40 second ray trace scene. I will try this with AVI as you suggest. Can you tell me what you mean by the same test with a different scene ? Thanks
