## Advanced video quality options

If an option cannot be edited, your camera does not support other options, or the value is set by the chosen profile.

### Encoding interval

This value cannot be edited and is set by the profile.

### Bitrate

To set a limit to the data transfer. The default value 0 means unlimited. If you enter a value, data transfer is limited to this value in Kb per second.

### H264 Gov length

The interval in which the I-Frames will be coded in the video file. A value of 1 means that every frame is an I-frame. A value of 2 means that every second frame is an I-frame. Decreasing the number increases the video quality, but also the data transfer. For a description of the frame types, see:

[https://en.wikipedia.org/wiki/Video\_compression\_picture\_types](https://en.wikipedia.org/wiki/Video_compression_picture_types)

### H264 Profile

The encoding profile from the IP camera. MediaRecorder uses the Baseline profile and this option cannot be edited.

### Quality

The quality of the encoded video file. Higher number gives higher encoding quality, but also more data transfer over the network.
