First, I have to point out to my very basic, begginer knowledge. I've watched a bunch on videos on YT, read a lot of stuff regarding exporting problems, whether it's a GPU, acceleration, frame or any other error.
I've tried a bunch of things, but selectiong software only on rendering or on preview or both is a workarround, that I simply can not accept - why to buy and use expensive graphic cards if in the end you have to turn it off to be able to export.
Yesterday I found something that was letting me export 2 projects, that I couldn't export before that simple trick, so I have my fingers crossed it will work again the next time.
I have selected GPU/hardware both on project settings and in export media window - so no software! The trick is to select all files in project you want to export and copy them. Create a new sequence with same video settings, paste them and export it.
I have tried bunch of different approaches, but none of them worked in a way that I could repeat it succesfully. With other methods was just pure luck... One time did work, second time didn't. Hope it helps...
