In my opinion, 4K is overhyped and not as good as people seem to think.
Unless you are a video professional, you really shouldn't be using 4k. Especially if you are filming your podcast as I suggest.
4K is a resolution most cameras, and most phones can shoot in nowadays. Instead of being 1080 million pixels x 1920 million pixels, it is 3840mp x 2160mp
"4K refers to one of two high definition resolutions: 3840 x 2160 pixels or 4096 x 2160 pixels. 4K is four times the pixel resolution, or twice the line resolution (2160p), of 1080p (1920 x 1080 pixels). The other high definition resolutions in use are 720p and 1080i"

I know your new iPhone 11 lets you shoot 4K, but let me explain why I think it is a waste of time, space and effort:
1. It's Overkill
You don't need it. If you are putting out video content online using your podcast or not, 85% of that is viewed on a mobile device. The screen so small you do not need 4K resolution. Split tests have also shown that higher quality videos do not outperform lower-quality videos; in fact, lower quality often does better because they feel more authentic.
2. Takes up WAY to much space
The most important and the biggest reason I suggest you don't use 4K is the amount of space it takes up. 4K takes up a ridiculous amount of space compared to standard HD.
3. Slows Everything down
Using 4K will slow down your uploads to the cloud, it will slow down yours or your editors editing program, every time they send you videos to review it will take longer, it is just a pain in the ass.
The only time I recommend 4K to someone is when they only have one camera and want to simulate different angles.
You could shoot wide using 4K and crop in on each speaker.
Otherwise, I highly suggest staying away from 4K unless you are a video professional and know what you are doing when it comes to social media content isn't needed and won't affect your results.
