File size is huge

[threeweeks]

The file size of my recording is huge(138 MB for 22 seconds).
I am recording minecraft, and I do not know what is happening.
My pc is fairly decent
Here are the logs:

Yes, that's the expected bandwidth/size for the quality you configured, especially if the footage is high motion.

Yes, that's the expected bandwidth/size for the quality you configured, especially if the footage is high motion.

but if i were to make a youtube video thats 20 minutes long, it would be 7 GB, and thats unacceptable and confusing concidering when I download a youtube video, it is only 1 megabyte for 1 minute at a decent quality higher then mine

You are confusing what you upload with what YouTube transcodes (with heavy compression) and distributes (2 completely different things). lots of articles about how YouTube (Facebook, and others) ingest video and then transcode for more bandwidth efficient distribution

if you ask Why? the short answer is 99.9% of folks computers aren't capable of doing real-time encoding of highly compressed (recent codec), decent quality video. So, the fallback is to use the less demanding encoding (still hard) and accept a single upload live stream of H.264 source video, then using dedicated processing in their server farms to re-encode for MUCH lower bandwidth (and video quality suffers as a result) for re-distribution. If you are interested there are in-depth technical articles that go into the details (which vary by streaming provider, but basic concept is largely the same). Things like how many subscribers and 'live' viewers impact the re-encoding algorithms selected for a given video

For recording, and editing locally, then uploading, there are then other articles on how to optimize your local recording, and then post-processing video editing, so the final video looks 'better' once streaming platform re-encodes
*if* you are not editing the video, then you have to make sure recording settings in OBS are optimized.
if you are editing the video before uploading, the final rendered video settings is more important

It's difficult to explain that you're probably comparing two vastly different videos. The amount of detail in the original matters very much. The higher the detail, the higher the required file size. If you use game graphics settings with less detail, the resulting video is vastly smaller - with the same encoding settings in OBS. May be the creator other videos tuned down some graphics settings without telling you.

It's also the motion. Low motion requires less space than high motion. You record Minecraft as far as I remember, and I remember extremely fast paced videos where every frame is vastly different to the previous frame, so there is not much compression possible. If you do the same thing slowly, the resulting video is much smaller.

If you want to create small videos with the same (low) quality as it appears on Youtube, you need to set your recording encoder to "(same as stream)" and set the desired bitrate in the streaming section. To simulate a Youtube video, use something between 4000-8000 kbps.
