Hello guys so my friend wants to buy a laptop for editing 6K video footage on the road in the train or the bus. Now since we are in a poor country we are limited by a low budget so we are looking for the maximum price/performance ratio, not something that is super well but something that will get the job done and not having to wait for the laptop for a week to render one video, but I'm more concerned in the kind of components that we should be looking for rather than being absolutely specific on every model. I know we would need at least 4 cores 8 threads and high clock speeds and at least 16GB of ram but I can't understand the concept of graphics cards shortening video editing time and how they help at all in it. Is the video card essential and can Intel HD graphics be used for the editing process without huge compromises? I've heard about the Intel Integrated sync thing that speeds up the rendering process but then I saw videos of people who tried the feature on Premiere Pro and it worked but after the render the footage was corrupted at some places, it had tearing and some glitches and that worries me. Then they try again without the feature enabled and the rendering is fine. Can someone tell me what's going on there? Is this because of the feature or hardware/ program/ immature version of the software? Does the newest version of Premiere Pro fix this? Please let me know.
I know it's a hard one and that's why I'm asking here in the first place, it's a bit of a complicated decision. But I hope that someone can help me.
I'm from Europe, It doesn't matter where I'm from i'm just asking for a recommendation on specs not specific model or deal. And yes, no matter weight and battery life, just for orientation.
