I'm sure my version of PowerDirector 365 has 'Updated' since then.
One of my cameras is a Fuji X-T3 that creates video files in MOV format, 4K.
I just loaded in a clip of around 25 seconds and tried to produce it - no editing, just make a h.265 4K MP4 file...
When I hit 'Start', the program just sat there doing nothing...
So I changed settings and tried to produce a h.264 MP4 file in HD - 1920x1080.
No problem at all - PowerDirector raced through the re-render and the file worked perfectly.
I then went back to an old file from my camera - that I KNOW worked perfectly last April when I edited the holiday video.
Again I could produce an HD file without issue.
Once again, using h.265 4K produced nothing...
So I tried to produce using h.265 but having the resolution at 1920x1080 to see if it was h.265 causing the issue.
It produced a working video in a matter of seconds, so it's not the h.265 setting that's at fault.
I then decided to play with some GoPro footage.
The GoPro files are MP4 4K files, straight from the camera...
This time, PowerDirector was able to produce and render the 4K output without issue !
Nothing in my computer hardware has changed since last April when PowerDirector worked perfectly well producing 4K files from my Fuji camera.
I made myself a coffee as I pondered what was going wrong...
I just left the program not producing at 0%
I came back to see it had finished !
However, the file was 'Sound only' no picture...
The produced video appeared in the media list with a music symbol in it...
I've no idea why the program just decided to produce a sound only clip after a delay !
So I'm using the same camera, same computer... But my 'Updated' PowerDirector seems to have forgotten that it used to produce files from this camera perfectly well... (Better if I kept hardware acceleration switched off - another story)
Can anyone throw any light as to what's going wrong or how best to fix this ?
