These indicators allow you to see the current algorithm. These are not control buttons; they are read-
only indicators. They are mainly useful in Auto Mode, to indicate which algorithm – Inverse Telecine or
Motion Adaptive – is currently being applied. They are also useful in Inverse Telecine mode to show
whether telecine content is present and the Inverse Telecine algorithm is being applied.
A green arrow (Figure 36) marks the mode currently in use. A dark grey arrow marks a mode that is
possible under current control settings but not currently in use. A pale outline arrow marks a mode that
is not available with the current control settings.

With inverse telecine enabled, when telecine content is detected, the five Cine Phase dots show
whether the 3:2 pulldown sequence is shifting. If it is shifting, the green marker shifts. This happens in
mixed telecine/video content, and also in content that was converted to telecine and then post-edited
in the video domain. Whenever a shift happens, a few frames are not deinterlaced. If these shifts are
frequent, you may have to switch to Motion Adaptive deinterlacing for consistent quality.
When the telecine detector locks the first time in a streaming session, the leftmost Cine Phase button is
green. If the telecine sequence is perfectly coherent, the phase never shifts. Once it does shift, the
absolute phase of the Cine Phase display (which of buttons 1 through 5 is green) is not significant – the
only significant fact is that phase shifts are occurring. When the sequence relocks, all phase buttons are
equally correct.
