I have a terrible 200$ chromebook that I’ve successfully edited clips in 4k.
It has a low power 4 core arm processor, only 4GB of ram, and a tiny 16GB onboard emmc memory ( like an ssd, but laughably slower ).
I used kdenlive to open the clips, and do some basic editing. It doesn’t play back the clips in realtime, but you get an idea of what you’re looking at in a thumbnail, and with patience, make cuts and transitions then render the results. Hitting the play button in preview just gives you a little slideshow style playback instead of smooth video.
4K is especially slow, takes two hours to render 4 minutes worth, but if you send that file to youtube or throw it on a card/thumbdrive for your 4k tv, nobody will know about the ghetto setup you used to create the clip.
As a bonus with youtube or other video sharing sites they’ll transcode it to lower settings, so once you’ve uploaded your 4k you can view it on an underpowered device in 720 or 360 or whatever, but those with better devices can see the high quality clips.
Obviously I prefer to review and edit video on a more powerful setup connected to a 4k monitor, but it’s not impossible to do things with budget gear if you’re willing to wait.
i7 with SSD in raid0 and 32GB RAM and 1080ti video would be a great setup, but you can certainly get by with i3s and 8GB of ram with on board video if you’re just learning to cut together clips and figure out what you want out of your new drone footage.
