Hi, and thanks to both for your replies.
My laptop is 5 years old, but I believe it has good specs even for today's standards. It also allows the Metal Rendered. BTW, I'm editing VR video, 5.7k (5760 x 2880). It's a bit slow, but it works smoothly if I set the previews to the minimum resolution and toggle off the filters when editing.
I've been doing some tests to understand why your laptop is showing hardware encoding and not mine, and I've found an explanation.
When I export, if my video is smaller than 4096 pixels, then Adobe Premiere allows hardware encoding. If it is more than that, then only software. 5760 seems too high to handle but I haven't read anything about limitation based on resolution.



I wonder if a more powerful machine would have hardware encoding for 5.7k in h.264 or is a limitation for everyone.
So now checking more on Nvidia, it seems to be pretty normal to cap based on resolution. Only newer and expensive models allow more than 4K hardware accelerated encoding. I guess is the universe telling me that I need to buy a new computer? 😄
