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. If a level is manually
set in this case, then other parameter values may not exceed the
permitted maximum values.
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 131)".
• 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.
