...would i get it to play better with new card or gaming pc, the reason i ask ,is i would like to edit said videos
@chrishal ... your question is very general & also a bit of a guess work, we don't know anything about the specs of your present computer, what player you've used, what settings you've used for the video clip & what editor you will use for editing later on.
Simply said... yeah, a new NASA grade computer will likely handle everything you can produce out from a
Mini 3 better & faster than your computer.
Video specs, good enough computer specs & possible post edit is actually a pretty comprehensive subject with a lot of components to weigh together & on top of this comes how long time you feel is bearable to wait for a rendering after a edit... & how much $$$ you're prepared to put into this.
Here below some knowledge around what's putting load on the computer when working with video files & some minimum specs computer wise for handling 4K video files in an acceptable way.
About the video file:
4K video isn't just 4K...below have major impact on the playability...
-Resolution, (higher usually gives less impact compared to below 3)
-Codec, (H264 or H265, kind of a go/no go effect)
-Bitrate, (higher values usually puts on a lot of load making the computer struggle)
-Framerate, (higher usually have a great impact on the playability)
About minimum computer specs for 4K:
-At least 4 core processors is desirable - Intel 6th Gen or newer CPU, or AMD equivalents, such as Ryzen 5 or 7th line of processors.
-16 GB RAM minimum for 4K videos.
-The video card at least 4 GB, Nvidia GTX 1650, preferably newer - for example Nvidia RTX 2060 or 3060, AMD Radeon R5 or later.
Additional tweaks that may help:
-Update your graphic card drivers.
-If you are editing on a laptop, make sure it is plugged in.
-Copy your 4K videos to an internal SSD for faster processing.
