I can confirm that at least some MOV 10 bit files are supported...
My Fuji X-T3 produces 4K, h265, 10 bit, 400mbps MOV files and they import into PD18 no problem.
I say "No problem" but there is a caveats...
If I record using 4K, 10 bit, LongGOP using
HLG, then there
IS a problem !
If I subsequently apply a LUT to the footage, then PD18 'Produces' a black screen video with just sound - If I don't apply a LUT - then PD18 'Produces' the file correctly !
If I
don't record using
HLG, (Choosing any of the other recording options), then I
CAN apply a LUT or any other colour correction without issue. (??? ! )
This is just something I've been avoiding, using the 'Eterna' or similar film simulation recording in camera.
I had no idea why this was happening and no information was forthcoming from any forum post - However... I note from looking at the 'Supported file formats' list as suggested by AshWilliams in this thread (I had to manually paste the end of the link)...
There is a note regarding HLG 10 bit MOV files that reads...
"PowerDirector now supports 10-bit HDR* video import. HDR 10-bit BT.2020 (HDR10 and
HLG) is converted to SDR 8-bit BT.709 during import."
I wonder if this is where the issue occurs ?
