So I did a Stardew Valley recording which is about 1hr but is over 14GB?

My settings are:
-Output:
-Type: Standard
-Recording Format: mp4
-Encoder: NVENC H.264
-Rate Control: CBR
-Bitrate: 50000
-High Quality
-Audio:
-Sample Rate: 48khz
-Channels: Stereo
-Video:
-Base (Canvas) Resolution: 1280x720
-Output (Scaled) Resolution: 1280x720
-Downscale Filter: Bicubic (Sharpened Scaling, 16 Samples)
-Common FPS Values: 60
-Advanced:
-Process Priority: High
-Renderer: Direct3D 11
-Color Format: NV12
-YUV Color Space: 709
-YUV Color Range: Partial

If you need anymore information let me know, also what good setting should I have (running GTX1060 8GB RAM)
 
Well it's not. You're doing several things wrong when you use CBR for recording instead of CQP/CRF
1> You're HARD capping the effective quality of your videos at that bitrate
2> You're MASSIVELY wasting bitrate in situations where the complexity of the recording doesn't need that bitrate
3> You're potentially introducing performance issues (more common with nvenc)
 
I don't want to come up as wisecrack, but please do the math yourself before complaining that a video gets too large.

Bitrate 50000 is actually 50.000 kbps, which is 50.000.000 bps, or 50 mio bits per second ("50 megabits").
8 bits are 1 byte, so 50.000.000 bits per second is 50.000.000 bits per second / 8 bits per byte = 6.250.000 bytes per second.
You' want to record one hour, which is 3600 seconds long.
Thus, the resulting video is 6.250.000 bytes per second * 3600 seconds = 22.500.000.000 bytes, or 22,5 GB.

That makes no sense to me lol
 
You should try to make yourself familiar with the meaning of parameter values you encounter while configuring software. Without understanding, you will always copy stuff from somewhere else without the slightest clue what it means. There is ton of documentation and teaching material on the web about this stuff. Wikipedia articles about stuff is always a good start.

And if you don't understand my small math example, which is elementary school level, you could perhaps spend more time on your school education instead of making video streams. In case I sound like your mother, I'd say to you: Listen to her! She's damn right!
 
As they suggested, move to something else than CBR for recordings, if not then 720p 60fps recordings don't really need 50000 bitrate, try half that (won't notice much of any quality change).
