Well, buy VideoPad is my suggestion, if you haven't already! Where are you transferring the movie from? For my part, who uses the Samsung Gear 360 2016 model and the Samsung S7, all films and images must be transferred to the mobile phone first and then transferred via cable to the VideoPad. And yes, it takes an incredibly long time when it comes to 360vr films.
I have a desktop computer with:
Windows 10 home
Intel(R) Core(TM) i7-7700 CPU @ 3.60GHz 3.60GHz
16.0 GB of memory
MSI NVIDIA GeForce RTX 2060 VENTUS GP OC - 6GB GDD
And three ssd disks.
But most of my problem can probably be referred to the mobile phone. Will check if the samsung s10 is compatible with my gear 360 camera.
I don't regret buying VideoPad. but you should have the latest version, yes.
I haven't chosen any special video card when I render movies, I just use VidePad. But I know that in my laptop that I have two different video cards, I have to go into the bios and choose which of the graphics cards I want to use. Something else you can do is start the control panel for your video card and see if you have any options there!
