I know you guys did a video explaining how you guys feel about using Linux for doing Video editing work, but with companies like The Foundry and Houdini I think it would be nice to see a video with more emphasis on those environments running on Linux.
I'm not sure how much you guys invest into watching Making Of videos, but in The Hobbit trilogy, I noticed some of the desktops have the old default KDE desktop wallpaper. I know it's probably compositing that they use those workstations for, but I'm pretty sure digital compositing falls under the category of Video Editing.
I've been under the impression that a lot, if not most, of the high end, Hollywood level special effects are done in some sort of linux environment, and have been for a decade or more. Part of the explanation I heard had to do with upgrading the tech from the old Unix days, and people finding it much easier to port the programs to Linux than to Windows or something else. As that should indicate though, I think they use pretty specialized and expensive software, or in-house custom software, for that high end.
On the other hand, I do all my video editing work in Linux for the show I do with my brother, and I started video editing in linux when I was working for this grant project where we did a number of things, including produce a show for PBS. Most of the other people were Final Cut Pro users, but some picked up on OpenShot along with me since it was a lot easier and way faster to get stuff done (saved the day a few times when we couldn't get something working in Final Cut Pro and I had to literally get the same video made, rendered etc in OpenShot. Had time to add in some extra transitions too!)
In any case, there are some nice suites for various multi-media production for linux now, and some decent distros with that in mind (Ubuntu Studio, AV Linux, etc), that come with a lot built in.
