Graphics card supported for video acceleration

[MavBoss86]

Hi all,

I'm totally new with videostudio, and I'm enjoying the sw. One thing that I don't understand (and don't found an answer) is which videocard is able to accelerate the editing/rendering and playback of video. I have an HD5870 1GB and modifying a 4k video done with my phone the graphic card is not used to playback the preview. Is there a list of graphics card supported by videostudio?

Thanks in advance!

I don't think any such list exists, or if it did, how long it has been since it might have been updated. All I know is that NVidia cards seem to have a better chance of working in accelerated modes since they have CUDA. But it also seems that the CUDA coding in successive versions of VS has not kept up with the CUDA versions used by more recent cards. So it is questionable whether even they will work well. And reporting here by a relatively wide group of users on this question point to the acceleration function being nice in theory but pretty light in reality in terms of measurable speed increases in the various functions compared to the speeds obtained when those boxes are not ticked.

Isn't the answer that I expected... But I think videostudio is based on some tech, like CUDA or OpenCL. Maybe it support QuickLink of Intel. Is an answer to this question, or someone that have experiences on editing 4k video and have smooth playback? I don't really need super fast rendering, but smooth playback yes.
Thanks

To get smooth playback when editing 4K, you need to set your Settings/Preferences/performance tab smart proxy option to ON (tick the box). Doesn't change the rendered result (the rendering still takes a lot longer because it is 4K), but does speed-up/smoothout any playback in the timeline whilst editing.

There's a good tutorial on this (1st in a series) at

and note the display standard may need to adjusted for your country standard (NTFS is the one shown but PAL and SECAM are also options. Make sure you choose the one which fits your installation. If you just chose your country from the list when installing, VS did that automatically. If you just took the defaults when installing VS, then if you are NOT in north america or Japan, you are stuck with the US NTFS standard anyway. Ways to fix that are not easily available, and an Uninstall then re-install with the right country chosen may just be the easiest way).

Otherwise, a super-fast 64bit processor and lots of RAM might suffice (a games machine)?
