Virb Edit doesn't utilize GPU hardware when exporting 4K videos.

Hi,

I have very powerful video card AMD Radeon HD 7900, which works great with latest games. For example Battlefield 1 is very resource hungry and yet my videocard handles is perfectly.
This card is also can be used to utilize cryptocurrency mining easoly. For example litecoin mining can use GPU to make complex calculation.
It is sad that Virb Edit can't leverage GPU calculation power. It takes 6 hours for Virb Edit v5.1.3. to export 16 minutes long 4k Video. Please implement such an ability to use GPU calculation power when working with videos from Garmin Virb 360 camera.
System configuration screenshots attached.
Thanks!

For me it works fine on nvidia gtx 970. Do you have the latest drivers for your amd card?

Your problem is Windows 7.
Me too I have a pretty powerful video card and Virb never used my GPU for exporting until I was using a friends computer to do some video editing and then I noticed that the export went thru like a bullet. After investigating "why", I concluded that it was due to my friends computer running Windows 10.

I upgraded to Windows 10 once I got home and lo and behold, my last video export that took well over 10hours went thru in less than 30mnts... no hardware change whatsoever.

So my conclusion is that Garmin is using some sort of API to access the GPU that either is not available on Windows 7 or something like that.

This is exactly correct. The Windows H.264 encoder did not allow hardware acceleration support for videos above 1080p until Windows 10, and encoding is by far the most computationally expensive part of exporting a video. If you export 1080p video you'll see your GPU getting used for that. I should also note that all modern video cards come with specialized circuitry that only does video encoding, and thus does not interfere with general card performance (So you can play battlefield 1 and live stream it without slowing down the game). I've never tried it, but I suspect encoding video may not show up in GPU performance profiler apps.

I need to start saving another $120 for Windows upgrade to Windows 10 :(
