Enables early exit from TU depth recursion, for inter coded blocks.

Level 1 - decides to recurse to next higher depth based on cost
comparison of full size TU and split TU.

quad-tree begins at the same depth of the coded tree unit, but if the
maximum TU size is smaller than the CU size then transform QT begins
at the depth of the max-tu-size. Default: 32.
+
+.. option:: --complex-analysis <0..4>
+
+ Increases the RD-level at points where the bitrate drops due to vbv.
+ The number of CUs for which the RD is reconfigured is determined based
+ on the strength. Strength 1 gives the best FPS, strength 4 gives the
+ best SSIM. Strength 0 switches this feature off. Default: 0.
+
+ Effective for RD levels 4 and below.
