A quick test to see if you have the JCE Unlimited Strength Jurisdiction Policy files installed. If you don't, in Java 6 you'll see 128. If you do, you'll see 2147483647. Thanks to http://stackoverflow.com/questions/11538746/check-for-jce-unlimited-strength-jurisdiction-policy-files

GIF to WebM with ffmpeg

Grab ffmpeg from https://www.ffmpeg.org/download.html

The most trivial operation would be converting gifs:

ffmpeg -i your_gif.gif -c:v libvpx-vp9 -crf 12 -b:v 500K output.webm

  • -crf values can go from 4 to 63. Lower values mean better quality.
  • -b:v is the maximum allowed bitrate. Higher means better quality.

Rendering in Blender on a machine with multiple GPUs

Rendering in Blender on a machine with multiple GPUs

So here's the premise: For scenes that take around a minute or less to render, performance is actually worse if you render on all of the cards with a single instance of Blender. This is because (AFAIK) there's a bit of additional time necessary to collect the render results from each card and stitch them together. That time is a fixed short duration, so it's negligible on larger/longer render jobs. However, on shorter render jobs, the 'stitch time' has a much more significant impact.

I ran into this with a machine I render on that has 4 Quadro K6000s in it. To render animations, I ended up writing a few little scripts to facilitate launching 4 separate instances of Blender, each one tied to one GPU. Overall rendertime was much shorter with that setup than one instance of Blender using all 4 GPUs.

The setup works basically like this. In my .blend file, I embed 4 text files, batch-render0.py, batch-render1.py, batch-render2.py, and `batch-rende
