I can't get AMF to work with hitbox. The stream has audio but just a black screen for video. I've tried various settings but nothing works. Local videos are fine. Unchecking AMF makes the video show up but it's pretty messed up visually. I can't see anything in the log that indicates something broke myself. I've tried the last 3-4 versions. 14.9 Drivers.

I've tested intra but something gets corrupted like it's missing first keyframe. Everything is gray and has the sweeping horizontal 'refresh' line visible.

But it looks like there's some need for MaxQP and MinQP controls as these even work with CBR. MaxQP at 48 helped a bit with the banding (though I did only a few minute test run). And limiting MinQP might keep bitrate from peaking even more. I'll try to post a bui

I was worried about that. I thought just a simple h264 setting would enable it but I shortly realized I was under a placebo with it.
so yeah, what your saying makes sense. The first frame is the full idr then after, it sends the intra-refresh

Hey guys. A problem has developed with my version of OBS. Whenever I'm streaming and there's no action, kb/s is ~1200-1300. Whenever there's any action at all, it shoots up to 5000+. Settings are pictured below:

Any idea on how to fix this?

yes, first use CBR. Check cbr and padding. Quality balance will always cause this. You are using vbr at the moment meaning variable. Use amf instead of ocl imo and set your GOP to 60.

Same deal, audio with black screen.

IDRPeriod is 0 in your log. Do you have custom settings enabled (usually no need to have it enabled)? Set it to 2x fps for starters. Also, as you want to stream, enable CBR and CBR padding.


Does anyone use IDRPeriod at 0 to get bunch of P-frames (better pic quality, for local recording etc)? Otherwise I guess I'll set it to KeyInterval by default for CBR as there have been plenty of post about getting black-only video already :P

IDR is still needed for local due to seek locations and with local they can push up the bitrate which improves the IDR frame that much more.

That would be great to set it to key frames. another question, in the default OBS, what is the GOP set to? Curious, because I know that YT recommends 1/2 fps, I have it set to what my fps are and some people set it to double fps (for local recording).

Last question I promise, I was reading about I pic period, what is the purpose of this? and is there really any reason to set it to 1 (default is 0)?

Suddenly everything works with IDRPeriod at 60! I was using custom just to use the quality preset, everything has been working great otherwise.

2014-10-28: Added MinQP/MaxQP setting: 32bit, 64bit.

If IDRPeriod is 0, it is set to 2x fps or KeyInterval. If you want, manually setting IDRPeriod to -1 in profile file should force it to 0.

I'm enjoying the new buld with qp options. So far looks good but waiting to watch the VOD's.

That worked, but my video looks a little pixelated during movement now.

without seeing the original source, that is what you can expect from 720@60fps with 3500 bitrate. youtube lowers the fps to 30 so you wont see the full fps like you would in 60fps. 60fps will mask pixelation with its high fps but when transcoded by YT the pixelation is more pronounced.

either way, it doesnt look bad

I'm using DirectX 11 because Mantle is'nt working yet.

I attached the crash report for BF4.

What is QP and how do I use it? Sorry, I'm a bit confused O.o
Click to expand...
The lower the number, the better the quality, but the higher the possible bitrate spikes.

EDIT for clarity: setting QPmax to low will not allow the stream to get pixelated at the expense of a higher bitrate during high movement scenes. QPmin to low and your quality will be great all the time, but your bitrate will (more often than not) go higher than what you set it to.

Have you tried vanilla OBS or using x264 encoder? But looks like it is either capture hook as there are some Raptr dlls loaded that probably conflict with OBS's hooks. or buisness as usual with BF4.

Still getting pretty crazy pixelation during movement. I am 1080 scaled to 720/60, using quality preset in AMD Advanced area @ 3500.

Anything I need to change here?
Click to expand...

Everything looks alright; maybe can you give a specific place where pixellation is happening? Also, not sure if you could point to source instead of YT. even though your coding on YouTube 720@60, it would help if you could send the twitch source and point out the exact time of the pixellation..

Something to play with is slightly lowering the max QP, this should try and force the encoder to a higher quality at the expense of going over your bitrate a little during high movement. I only see slight pixellation from the video watching on my 1080p phone.
