a level is manually set in this case, then other parameter values may not exceed the

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 304)".
• MBAFF (macro block adaptive frame field): A macro block consists of 16 x 16 pixels.
The encoder creates a "frame field" on this basis for encoding.

The setting "Level auto" specifies the encoder levels automatically, among other things for
the resolution of the video format specified under "AVC preset" and the set profile bit rate
Field order
Note: This parameter is only available if the setting "Field" is selected for "Picture type".
