   If I was aspera or filesociety, I'd be rather worried. I'm planning on using this to sync terrorbytes between london and LA. Why should I pay the ridiculous cost of a thinly wrapped rsync over UDP when I can have it for free? (the latency b

   An extra cone may not necessarily allow you extra colour resolution. For example it might mean that there is less over all resolution (cones might not fit together properly) also the brain might not be using them, as there is no need. (opti

   The problem with some AMOLED screens is that the different colours efficiency decays at different rates. Which is why early versions of the galaxy(or similar samsung phone) always has that horrid blue-green tint to it. Another problem is am

   The classic adage is: A CEO walks around the office floor and notices how wonderfully clean the place is. This CEO is all about efficiency, so he trots into his office and phones up the CFO. He asks how much is spent on cleaning, suprised a

   1) 100% yes 2) yup 3) Frequently read/written files will be stored in ram 4) This still affects DBs, as they are still a layer above the FS. 5) GPFS, GFS2, ceph, cleversafe, tahoe-lafs, all make this go away. 6) ZFS has snapshots. Snapshot

   Now the interesting thing about this post is this, I can see why they wanted to use mongodb, and I can see why it bit them in the arse. What interests me is why they would want to keep everything in the database? I'd assume that they need

   Depends on the application, In broadcasting for example bandwidth is painfully expensive, hence the shift from MPEG2 to h.264 for consumers (although in the US its much more complicated as everyone seems to recompress everything badly on TV

   The thing that replaced 35mm with a digital format is DCP. Basically its Jpeg2000 in disguise. The problem with uncompressed formats at high resolution (like cinema 4k, and its smaller "UHD" cousin.) is that they eats bandwidth. Full res

    This is true, but the are pre-rendered for a reason. Anything with water you're looking at 24hour+ sim time, plus render, and 1tb of data plus. SubSurface Scattering (translucency) takes a huge amount of CPU time.

    Gleaning useful 3d models from 2d images is rather error prone. Hence why all the cool kids are using wavelets, as they are inherently more reliable on 2d images. Movie codecs are hard. However jpeg2000 and similar wavelet codecs (like Red'

    Using 3d space to represent movement of the textures. Currently a frame is split up into blocks, and they are moved about in 2d (X&Y). Using a 3d model of the movement would theoretically gain you some savings, as it would require less

    h.264 yes. VP8 not so much.

    +1 There is a massive amount of high quality content, encoders and transport tools. Even when h.265 is properly ratified its going to be at least 2 years before we see mature tools/content.

    I can understand the appeal, however its just not that feasible on low powered devices(Yet). Most mobiles (most things videos infact) have some silicon dedicated to h26 x decoding. Using that silicon is a massive order more efficient (both

    I would suggest that whilst it can be used for grading, its an editing tool primarily. Baselight(and davinci resolve) on the other hand is a grading tool, however it can be used as an editor.

    or if thats not good enough: http://www.openexr.com/ has photoshop plugin aswell. No real support in the gimp though (cinepaint possibly has it though.)

    There are already formats that allow you to keep n layers of images. openEXR for example allows you to keep multires, multi bitdeptph images all in the same file, with lots of metadata It also has options for byte order to allow faster read

    Nuke, smoke, flame, faire, maya, modo, baselight, resolve are all on linux. ILM, pixar, Dreamworks, Weta and SPI are all pretty much linux only shops.

    The Addon cards allow you to playout to tape+. Its nothing really to do with cuda, as editing is mostly IO bound (even with some effects) +yes people still use tape. Everybody can read tape and the colours are going to be correct. Its also
