Profile/Level

Profiles: Profiles define the encoder properties that are supported.

Level: The level determines which bit rate and resolution are possible for the video.

Picture type
"Picture type" specifies which parts of a frame should be used as the basis for the
encoding:
• Frame: A frame is a single image from a video sequence, also called a full image.
• Field: A half-image, two of which combine to produce a frame. Read more about
this explanation regarding "Interlace (view page 349)".

Field order

Note: This parameter is only available if the setting "Field" is selected for "Frame
type".

In case of interlaced streams, the half-image sequence is set. Read more about this
explanation regarding "Interlace (view page 349)".

Slice count

A frame can be divided into multiple slices for encoding. Specify the maximum
number of slices are permitted. If set to "0", then the number will be determined
automatically.

Rate control
The bit rate indicates how much data per second is saved in the video (playback
speed). This makes the bit rate the deciding parameter with regard to the file size and
quality of the video to be encoded. A higher bit rate means more quality but also a
larger file size.

Mode
• Constant bit rate: The constant bit rate should only be used if the device used to
play the video supports constant bit rates.
• Variable bit rate: The bit rate varies. For faster movements in the video, the bit
rate increases, and for still images or slow pans, a lower bit rate is sufficient for
creating the video in constant quality.
• Constant quality: Similar to the "Variable bit rate" mode, the bit rate varies
according to the video material. The quality depends on the selected profile and
can be changed.
