What does my PC need for 4K video editing?
Q My five-year-old HP PC has an Intel i3 processor and is getting a bit slow for my needs. I want a desktop PC that I can use for basic editing and viewing of Panasonic Lumix G 4K video shot at 24 frames per second (fps). I read the reviews in every issue, but you don’t always say if the gaming PCS are suitable for 4K video.
A Any PC with a recent i5 desktop processor, such as the Palicomp i5 Titanium (£500, see page 21) will play 4K video smoothly and should be fine for basic editing. But what’s basic? You may want to apply colour correction, transition effects, and perhaps more demanding options such as motion tracking (see screenshot) or stabilisation. Even a powerful PC will struggle to render these as you watch, so you can put up with choppy playback (until you render the final version) or wait for effects to pre-render every time you make a change. An i7 will speed things up, as would a graphics card if your software supports it. Start with the system requirements for your editing program. Then use Google to find discussions between users on PC specs that they’ve used successfully.
