What total bit rate should I go for in 4k?

Hi,

I'm exporting 4k clips and having a few complications.

I managed to get 2 clips under the 1.8gb requirement with premiere cs6.
Should I go with the one that has the higher total bitrate?

What is the final total bit rate that works fine for you for 4k?

Is 202402kbps enough for good 4k video?

Also, how big should a 20 seconds clip in 4k be?

Thank you.

There isn't a strict rule on size and if there still is,it is not imposed.Many of my 4k prores files are over 2-3gb's.

It depends on level of details: higher bit rate means, generally but not necessarily, more details, better gradients.

Thank you!
