25P playback in PPro source monitor IMac 5K using Blackmagic IO outputs 50P
The effect is 4 seconds black as monitor re syncs when I switch between 25P program monitor and 25P material in the source monitor. Occurs on iMac 5K not MacBookPro.
This occurs with:
25P AVCI footage in mxf wrapper from Sony F5 and
25P AVCI mxf op1a export from PPro
Playback in Source monitor is reported as 50P by BM Desktop Video and the monitor.
A sequence created by dragging the clips to create (thus matching 25P AVCI) reports as 25PsF in BM (and thus 50i by monitor)
Modifying the clip interpretation to 30 frame interlace can result in 60i and then adjusting to 25fps can result in 50i but this doesn't appear consistent.
This is on an IMac 5K using driver 10.6.4 with El Capitan up to date and CC2015.2 up to date.
The issue occurs with both Ultrastudio 4K and MiniMonitor (the MiniMonitor downscales the 50P to 720/25P
The issue DOES NOT OCCUR with the same project/media/drivers/software/IO on a MacBookPro.
I'm not sure if this indicates a bug in PPRO or BM driver.
Thanks for any help or confirmation or otherwise of this problem on a similar setup
