bitrate fluctuates ALOT with 32.0.1

Hello, i reinstalled windows last night and downloaded the latest version of OBS studio and imported my profile but today i streamed and I noticed my bitrate which is set to 8000 went to peaks as high as 9000 and as low as 7000. this has never happened to me before, my bitrate was actualy really solid and stayed around 8200 constantly. Is this a issue with the newest OBS? please help me!

just wanted to double check you didn't have anything configured incorrectly, all looks fine here. bitrate fluctuations can be normal and even dependent on the service itself. I would test 6000 bitrate and see if it stays pretty steady, if so you know this is being done on the service side of things but either way it is not anything to do with a specific version of OBS or even OBS itself at all.

Dear prgmitchell I really hope this message reaches you I wanted to let you know I discovered something very strange. the big fluctuation in bitrate only happens when im in my Starting Soon scene. I then realized that when I disabled/hide the mp4 media file from my sources the fluctuations would go back to normal. is the mp4 file I use for starting soon in loop the culprit?

0. Static content uses less bits compared to dynamic/moving content.
1. The Hardware-accelerated GPU scheduling ("HAGS") feature in Windows is currently known to cause performance and capture issues with OBS, games and overlay tools. It's an experimental feature and we recommend disabling it via these instructions.
2. Run OBS as Admin
3. Your current bitrate of 8000kbps exceeds their max video bitrate limit 6000kbps. This may result in the streaming service not displaying the video from your stream or rejecting it entirely.
4. Your log doesn't show any bitrate fluctuations, but there may be quality fluctuations where's a lot of movement.

Thank you so much for taking the time to watch my log and reply to me!! Its so weird to me you say the log doesnt show any fluctuations because when i looked at the bottom right of my obs the green number which i assume is bitrate goes all the way from 7k to 9k and anywhere in between x.x do you think i should just ignore the number and stream?

Most people won't notice the difference in quality for bitrates between 7k-9k. Are you actually experiencing issues with the stream?

Not at all! my viewers say its completely fine.. I just happened to notice my obs started doing this after reinstalling windows and using new nvidia drivers and im just hyper focussed on it x.x

The log you supplied doesn't show any issues. No rendering lag, no encoding lag, no dropped frames or bitrate changes.

You're streaming with CBR, which you should be, the bitrate doesn't fluctuate... unless you have Dynamic Bitrate enabled but you don't. If you did, it would look like this:
Code:
21:35:23.429: [rtmp stream: 'adv_stream'] Dynamic bitrate enabled.  Dropped frames begone!
21:35:23.429: [rtmp stream: 'adv_stream'] Connecting to RTMP URL rtmp://a.rtmp.youtube.com/live2...

21:35:47.458: ==== Streaming Start ===============================================

21:36:11.939: [rtmp stream: 'adv_stream'] bitrate decreased to: 17900
21:36:15.949: [rtmp stream: 'adv_stream'] bitrate increased to: 20900, waiting
21:36:15.949: [rtmp stream: 'adv_stream'] going back to prev bitrate
21:36:15.949: [rtmp stream: 'adv_stream'] bitrate decreased to: 17900
