Yea, rendering time is the worst hahaha. Drains all of my RAM and the laptop is soooo slow, that I am not able to do anything. :/ Planing to buy more powerful laptop this year.

From time to time I tend to shoot my b roll in 4k. I guess I just like to have that extra resolution. If I need to use image stabilization, crop some parts of the image, making zoom ins and outs.
Most of our phones can shoot 4k, so why not use it. hehe

Will try to make a good explanation video in the future about why I am shooting 4k.
