Question / Help Dropped frames

Just a quick question. Can dropped frames occur when you have your max bitrate set higher than what you can actually stream, and how does the buffer size play into that?

If so, is there anyway to set OBS to maximize the bitrate in real time, because sometimes my upload is a little jumpy, and I would rather have it adjust lower, and get worse quality for that period and then go back up again, rather than lose frames, or always have it set low.

You drop frames when you try to upload faster than you can actually upload.

No, there's not. That's not a very reasonable thing to do be able to do, and even if it were possible, your viewers would have a very choppy stream anyway because of the amount that your bandwidth is fluctuating.

Maybe it would be possible to add a trigger? Like say you are streaming at 2000 kb/s, you could set the trigger to 25%, so it would only change when you either went up to 2500, or went down to 1600, and then the target values would update again, so for 2500 it would change to 3125 or 2000 before it changed again.

I know it probably doesn't exist in obs right now, but I think it would be a cool feature to add.

Oh, and yeah, if you couldn't tell I'm not exactly the most knowledgeable person about how this stuff works lol, but thanks for the quick response.

It would be interesting to be able to fall forwards and backwards in bitrate similar to how old computer modems altered their transmission speeds over the phone lines. But somehow I think Twitch would have a say in doing that, as they want constant bitrate, and this by definition wouldn't be constant.

"Dynamically" meaning it allows you do change it during the stream, not it automatically adjusting based on your connection quality. And you'll have to disable strict CBR to be able to actually use that, which Twitch doesn't like.
