Hey, Cyberlink geniuses. I've recently started to encounter quite a glaring problem during edits that I've not seen in three years of using PD.

Very often when editing, video that came from my Canon M50 camera will have elevated black level (or contrast, or brightness -- hard to tell). This will manifest in blacks being gray and washed out and an overall flatter image.

I initially thought this was just my proxy, but the finished render also has this problem, and it comes & goes. Very often it happens during transitions and then returns to normal video settings as soon as the transition is complete.

I've tried deleting proxy and even restarting PD just before a render so everything is "fresh," but that's not reliable either.

You can witness the problem in a recent YouTube video here: https://youtu.be/Olff3QmlXnA?t=79

The link goes straight to 1:19 as I dissolve from b-roll back to camera. Note that the black level of my shirt appears gray until the transition completes and then it returns to a dark black.

Here's an image from the video where I grabbed a still when the video is normal and when the black levels are elevated and I did a split between them to illustrate.

I'm quite stumped as to what to do next. I have no color enhancements or correction on this camera clip, but this popping up & down in black level is quite distracting and looks bad.

Here's hoping someone has an idea.

BTW, I'm on 365 and updated to the latest. The only recent change I can remember in the recent past is that I had to turn off hardware acceleration due to blue-screening, but I'm not sure that change correlates with the start of this issue.

Thanks.
