EEVblog #698 – GPU Video Rendering

Dave tests a really high end NVIDIA GTX-970 video card for accelerated CUDA GPU video rendering with Sony Movie Studio (Vegas) & also Adobe Premiere.
Will it work for the new high frame rate video ?
Will it work at all?
How about a Radeon HD7850 and OpenCL?
Does the CODEC matter ?
Does hard drive or SSD performance matter ?
This also provides some insight into how Dave edits and renders his videos.

NOTE: This is mostly trying out and real time commentary of testing video rendering speed. If you find this stuff boring then DON’T WATCH IT.
There is no electronics content here, but plenty of main channel viewers might find it interesting.

  1. The problem is that CUDA/OpenCL programming is still kind of an arcane art, even though they teach it at universities nowadays (at least at mine). And proprietary codecs tend to be a big mess that works using all hardware quirks possible (here it’s probably very old code that was patched up many times to accomodate for conversion to 64 bit platforms (and it isn’t trivial with C++ code that wasn’t meant to be portable and did all dirty pointer/bitwise operation stuff imaginable), modifying it to useOpenGL/DX/whatever technology was fashionable), so I’m not surpised it “doesn’t kinda work” on a new GPU. And that’s not even as bad as for example AutoCAD, where people tend to get few versions installed because of random crashes happening in certain situations. AutoCAD. It crashes on one project in 2012 version, then on another in 2013. With electronics you can at least get a scope and try to understand what’s going on;)

  2. It’s hard to find experienced people on this subject, however, you seem like you know what you’re talking about! Thanks
