Iv`e been doing video edits using Wondershare Filmora 9 with 1080p footage or a few months now and am now looking to make the jump to editing 4K video with the Adobe Suite. I wouldn`t be looking to do heavy editing of graphics or animation or anything such as this. Would literally be looking to cut and chop up some 4K footage and have it render smooth with voiceover commentary thrown on top of the video.

I`m looking to buy a laptop capable of 4K editing and need your advice about whether a certain one I have been eying up is capable or not?

It`s a Lenovo IdeaPad 3 14in Full HD Laptop:

AMD Ryzen 7 (Not sure of exact processor)
2.3 GHz with a burst speed of 4GHz
AMD Radeon RX Vega Graphics Card
512GB SSD.

Could someone possibly also let me know if the RAM on this rig is capable of being upgraded to 16GB as I know it will be necessary for 4K.

Much Appreciated.
