Help: OBS Studio gameplay recording file size too huge

[Ariortega]

Hello Steam mates,

I want to record my gameplay so I can upload it on youtube. But my oh my, the file size I get from OBS Studio is absolutely insane. I recorded 5:30 min. of DMC 4 SE with the following settings:

Output resolution = 1920 x 1080 @ 60fps, Lanczos,
Encoder = NVENC, Format = *.mp4,
Rate control = CQP, CQP Level = 20, Preset = High Quality.

File size was : 5,1 GB !!! I mean...what the heck? This can't be right for a 5:30 min. footage, can it? Imagine the size for a 30 min. or 45 min. gameplay footage....

Can somebody please help me or give me some advice how to reduce drastically the file size?
I don't wanna loose much quality.

(How do other (professional) youtubers record their gameplay with such quality but small file sizes?)

As always mates, I highly appreciate every help and suggestion. Thanks in advance.

davinci resolve is a free program and very good for rendering videos in different formats. i usually will render to h.265 and usually cuts file size in half with no loss of qaulity
