OK - Over the last 18 months or so, I've not shot any video and have had no need to edit anything...
Last weekend I went out with my camera, predominently shooting stills, but did shoot one small video clip.
I opened up PD (I Have 365). I then downloaded the latest version of the 'Application Manager', which then in turn asked me to update PD... So I downloaded and installed the latest version... (No surprise after 18 months or so)
All done, ready to trim up the video clip...

I use a Fuji X-T3 camera, it outputs its video in 'MOV' format.
You can choose a myriad of options, but I'm generaslly shooting 4K, 10Bit, Long GOP, 4:2:0 h.265 25fps...

Now, when I last edited a video, I simply put the MOV on the timeline, edited as required and 'Produced'.
All good.
This time, when I hit 'Start' on the produce page....
Nothing...
Nada...
PD just sat there looking at me, not 'producing' !

After playing around and swearing for an hour or so, I visited this forum and typed 'X-T3' into the search function.

This gave me a thread as below... Where optodata and JL_JL had been very helpful, but ultimately they confirmed that PD 365 didn't like the files produced by the X-T3 , it wouldn't 'Produce' them !!!!

Now I can catagorically state that back in November 2019 when I was editing my X-T3 files using the latest version of PD 365, it had absolutely no problems with my raw clips at all !
(As long as I didn't try to use a LUT on a HLG file !
Another story - https://forum.cyberlink.com/forum/posts/list/80256.page#330015 )

You can see that back when I was noticing that PD did like to 'Produce' from a HLG file off my X-T3 after a LUT was applied, I may have realised something else if PD hadn't been producing from any of my files !
They had been working perfectly well ! - And now they don't.
So - When I updated to the latest version of PD, It 'Forgot' how to produce MOV files from the X-T3 !

This may just be the last straw, I've been using PD for so many years, but I'm fed up with finding things I can no longer do...
Yes, I can convert my raw MOV files with handbrake before loading into PD, But I NEVER had to do this before,
why should I bother doing it now. I'm not changing my camera to suit PD 365... Cyberlink just decided to ruin the program for me (And any other X-T3, X-T4 owners) and they now charge me now for the privilege ! - At least a while back I could simply use an older version if I found a broken part - now I'm stuck with it.

Time to cancel my subscription methinks - unless someone knows that an update is almost here that will return the facility it used to have before I wasted money for Cyberlink to break it ?
