What Bitrate should I be seeing in BI

Post by olddawg » Sun Aug 26, 2018 4:34 pm

I have a couple of Foscam FI9900 P 1080P cameras that I am using with Blue Iris. The video settings on the camera are Bit Rate 2M, Frame Rate 25, Key Frame Interval 30, Rate Control VBR. These cameras are connected over WIFI to a TP-Link C9 Router and have a very good signal. When I look at Blue Iris Status for the cameras I typically see a Bitrate of round 240 kB/s and FPS/key of 25/0.80. is this typical of what I should be seeing.

That's more or less what one of my site's 2mps are at, so I think yes.

How can you list a fix bit rate of 2M in your first item then also claim VBR?

Let me rephrase that. I see a range of around 80 to 240 max. Is that typical?

...The video settings on the camera are Bit Rate 2M...
If your camera is set to bit rate of 2M you should expect BI to report 2M.

Thank you HeneryH. So you are saying in the Blue Iris Status Screen I should be seeing up to 2000 kB/s for the 2M camera. I am only seeing about 1/10 that? I am looking at something wrong?

No, I'm saying that of your camera is set to a bit rate of 2M then you should see 2000 kB/s. In your OP you said your camera was set to a bit rate of 2M.

Maybe you mis spoke on your OP and really didn't mean what you said.

There is a huge difference between a pixel count of 2M and a bit rate of 2M.

FYI - I have a 2MP camera @ 15 FPS and H265 compression. Currently set to VBR with a 'mid range setting on quality setting' * yields a BI bit rate of 550 kB/s.


* there seems to be a lot of confusion about my Dahua VBR setting with the 'quality setting' as no one can really explain how the setting relates to the end resulting bit rate.

Depends what your purpose of the video camera. Primarily video? What sort of video?

If your camera is set to VBR on the video stream then this is normal. You will see bitrate go up and down as the image sensor has more or less to show. FPS/key of 25/0.80 means, from what I can gather, that the camera is sending 80% of the configured framerate, which is pretty common. One thing though, I would set your keyframe interval to the same number as your framerate so that you get a new key frame every second.
