Filming in 4K
Filming in 4K can be useful in many ways. Sometimes, if you have the option, you might as well use it. But it’s not always needed and can sometimes be a burden.
Think about the devices your video will be played on. Say you have a camera that shoots in 4K but your computer monitor is only 1080p. You’ll only be seeing the footage in 1080p. If seeing the resolution is what you’re after, you’d need to upgrade your monitor.
Sidenote: 4K does not make every video look better. Bad lighting in HD is bad lighting in 4K.
Another thing to keep in mind is that filming in 4K makes file sizes larger, which means larger memory cards and hard drives might be needed. It also uses more computer power to edit with 4K footage. Things like timeline scrubbing and playback might be slower than normal.
But shooting in 4K is still a great option. If you put 4K footage in a 1080p timeline, you can scale in when you’re editing and the video won’t get pixelated. This is helpful in many situations, from scaling in like a second camera on A-roll footage, to changing the framing of B-roll shots.
The need for 4K depends on the project. If you have time to set up and frame each shot how you like it, you might be fine with HD video. But if your filming style is more rushed, having the option of extra resolution when editing might be helpful.
