Question / Help [solved]Recorded fullhd 2h very large

[Pi_Mac]

Hi,
I have set OBS what I though were good settings:
Screen Recording + Mic audio
NVENC h.264 .mov
scaled from 2k(monitor res) to 1920x1080 60 fps
bitrate 50000
High quality.

After recording 2h of gameplay my video is 38 GB and in Adobe Premiere it is laggy just to open it in source preview. VLC opens it and plays smoothly. I have tried to use Media encoder to make proxy video - toled me it would take 75h to make it

My specs:
16gb ram
i7 3770
gtx 1070

Where did I go wrong? Can you help me? So far I know that "Record game" instead screen might help as well as lowering bitrate. Is there anything else I can change? (I am a beginner)

It is normal. The file size depends on resolution, fps and bitrate (bigger values = larger file). You can try twice lower value of the bitrate. It gives to you twice lower file size and almost unnoticeable quality loss.

It seems you set your bitrate too high, what you can do is reduce bitrate (I think 15000-30000 is fine enough for most of people).

Ok. Thank you I will try setting bitrate for 15000 and see how it runs. Although i have recorded a shorter video whith the same settings and it was still lagging while being edited (in source preview). Is it also bitrate fault?

Depends on the editor, but h.264 video in general isn't well suited for editing anyway. As disk space is a concern for you, creating proxies isn't going to be an option, so you're probably just going to have to live with it.

 

[Pi_Mac]

Sorry if it sounded like that but it is not the disc space but rather not being able to edit the video. I was going for quality but if i cant edite it I need to lower it. I will record about 1-2 h everytime so i need to be able to edite it.

It's probably worth looking up on the Adobe web site about how to work with proxies in Premiere, in that case. I don't use Premiere so I can't tell you much on how it works in that software.

Ok I have found the solution. I am recording now with settings:
NCENC H.264
format type: mp4
Rescale 1920x1080 30FPS
CBR
50000
0
High Quality
high
auto

and in adobe in preview I can watch it smoothly and 40000 (maybe more) in 60FPS.

(proxie video also worked on .mov but it took like 10-20 min to encode 1 min length video)

It seems like mp4 format works form me and mov doesn't. Thanks for all the help!

You should be recording to FLV or MKV and remuxing to MP4 afterwards. If OBS crashes or is otherwise interrupted an MP4 file will be lost.

Yes, proxies take time to create. It's the tradeoff you're making in exchange for files which are easier to work with until you're ready to do the final render.
