This is a (83 minutes long) video of Team Orange conference talking about the making of Elephants Dream.
(From their web): "In it we mention a few things, including our version of what the story is about, and also some of the easter eggs and tributes that we hid inside, so if you’re interested, go and check it out!"
This is a very brief resume, as I go along it:
2:00 It was setup up with an unexperienced six persons team in some sleepless 7 months.
They spent 1 week to set up a teaser, and then 2 or 3 months to set up everything.
15:30 Crappymatic - from the first script
17:00 2nd animatic, more organized
18:00 Remove 90% of the dialogs and 30% of the scenes and start final animatic: unfinished but very similar to the final movie
33:19 rendering in OpenEXR and jpg to avoid huge file transfers
34:40 Scene and render file transfer between Amsterdam animation studio and USA render farm was done using rsync, over a ADSL line! (rsync seems quite UNIX-centric, maybe unison is better in a cross-platform environment).
36:00 They could not use separate render passes / layers for space concerns but they composited everything using blender composer so they obtained the final compositing straight away from a single blender scene.
37:00 Have to stop now. Anyone willing to keep writing, please post a comment!
There is also a previous "making of" video, both in 31 Mb downloadable version and in parts in youtube ( part 1, part 2, part 3, part 4)
