So i streamed content last night as tonight with the same settings and same internet connection, yet tonight the bitrate constantly dropped below 1000 and once event dipped so low that the stream stopped for 5 seconds. Last nights stream went off without a hitch. Why is there such a difference in bitrate and quality output between two streams
Please help!!

Real Upload speed of 212 Mbps tonight

General OBS settings:
Output:
Encoder:Nvenc h.264(new)
Bitrate: 4000
Keyframe intervals 2

Video
Base resolution and output at 1280x720
30fps
Bicubic downscale filter

network
Dynamically change bitrate to manage congestion box ticked

Please post a log with your issue! Here's how...

OBS Studio creates a log file each time you run it which contains very useful diagnostic information. Without a log file, it's much harder for any support volunteers to figure out problems and your post may be ignored. To upload a log file, go to the Help menu > Log Files > Upload Last Log...

I stream to Crowdcast via OBS so that I ca us the OBS features and not just have bobbing heads on the screen. Streaming directly to crowdcast without OBS I have no problem with connectivity and bitrate etc. the stream is fine. But the moment I stream to Crowdcast via OBS i get massive bitrate issues with the bitrate during the stream dropping to below 500 and then last night it just drops through the floor and kills the feed. Any help at all? I attach the log files. My upload internet speed is constantly above 200mbps and I cannot figure out why it is doing that! I have clients lined up who I need to help so my livelihood is on the line here. I would really appreciate help.

0. In many cases, wireless connections can cause issues because of their unstable nature. Streaming really requires a stable connection. Often wireless connections are fine, but if you have problems, the first troubleshooting step would be to switch to wired. We highly recommend streaming on wired connections.
1. Having the YUV Color range set to "Full" will cause playback issues in certain browsers and on various video platforms. Shadows, highlights and color will look off. In OBS, go to "Settings -> Advanced" and set "YUV Color Range" back to "Partial".

I am having the same issue. My bitrate is so low on VBR but my upload speed is around 35 to 40. I have attached my log file for your review

The log you provided doesn't show any dropped frames. If you are dropping frames, you can enable Dynamic Bitrate in the Advanced Settings. You can use VBR with Dynamic Bitrate; it will just lower the max bitrate.
