quantization parameter controls the amount of compression for every
macroblock in a frame. Large values mean that there will be more
compression, lower quality, and lower bandwidth. Lower values mean the
opposite.
Min QP: available when Bitrate Encoding is VBR. The range of values is
0 to 50. The default value is 4. And we recommend you use the default
value and do fine adjustment if needed.
■
Max QP: available when Bitrate Encoding is VBR. The range of values is
1 to 51. The default value is 40. And the value must be larger than the
Min QP value. We recommend you use the default value and do fine
adjustment if needed.
■
Code type: options are H.264 (default) and H.265(HEVC) encoders.
■
Encoding profile: for H.264 encoder, the profiles can be High
(default)/Main profile/Baseline. For H.265 (HEVC), it can be Main profile.
■
Quantization range: options are Full range(0-255) and Limited range(16-
235) (default).
■
AR convert: options are Ignore, Cropping and Padding (default).
■
Keyframe interval: options are 0.5, 15-300 frames, the default is 60. A
smaller number will result in a larger file size and less buffer time for seeing
the first frame. To ensure a clear and smooth live broadcast, it is
recommended that the key frame interval be less than or equal to 60
frames. Keyframe interval is fixed at 20 for NDI |HX3.
■
®
Time code SEI message: options are off (default), system clock, and
embedded. Turn on the switch to get A/V sync between multiple devices
which support this SEI message as well.
■
Closed caption SEI message: turn on the switch to encode closed captions
