Video file not opening in Photoshop 2020

The problem is not solved.

Macbook Pro M1, Big Sur, Photoshop 22.3. Newer had this issue before on previous versions of Photoshop.

Granted every access possible, reset settings twice.

Nothing helps. And yes, I can open these exact videos in any other program.

Video files just stopped open in Photoshop 22.3 on an M1 mac OS 11.2.2.  Went through this whole thread and tried everything, no dice.    Tried rending it a bunch of ways, tried saving it from quicktime ...

2021 and still nothing

drag the video file to your Mac desktop then "open" file in PS... Im uing PS 2021 Hope that helps

Quick tip:

While we wait fir this to be resolved, I have one workaround that has been getting me by for now. My main reason for wanting to open up the videos in Photoshop has been to pull hi-res thumbs. If this is the only reason you need to do this, consider this alternative method.

1. Open up your video in QuickTime Player
2. Scrub to the frame you want to use as a thumb
3. Hit CMD+C to copy
4. Go into Photoshop and create a new document from clipboard
5. Hit CMD+V to paste

Hope that helps!

I am also experiences the issue as described by other PS Users. Please, it needs to be be fixed!

Feb 2021 and I have this issue, I've tried all of the fixes in this forum and nothing works. It doesn't help that half of the fixes are for Mac and not Windows. I'm considering just cancelling my subscription because whats the point in paying for something that doesn't even work?

December 18th and this issue has obliterated any remaining fragment of hope that I had left in this god awful application. I spent 7+ hours on the phone with Adobe support yesterday and we got absolutely nowhere. Tried just about everything imaginable, including everything suggested in this forum post. Redownloaded, restarted, changed privacy and accessibility settings, downloaded older versions, tried uploading videos from external/internal drives, tried just about every video codec imaginable, changed preference and graphics settings, edited Trace Database.txt. Nothing worked. To say it was frustrating is a massive understatement. 

Today my ticket is being advanced to even more higher-ups with high-tech equipment. They made a bug report. I will update this post with any solutions they find. If worse comes to worst I might end up doing a factory reset. I'm willing to do anything at this point. This is an absolute nightmare. 

(here's a link to a Reddit post that goes into more detail about my issue

I too was struggling to try to find a solution on these forums. I tried both the PC and mac and neither worked, however, somehow I figured out that if the video is encoded in HEVC/H.265, then it won't open. After you convert it to H.264 then it should work, at least it did for me.

This is the 3rd time in a month an adobe product has seriously malfunctioned for me and many others as I read these forums. To make me even more bitter I spent 2 weeks with Illustrator and InDesign not working; then manically searched and found a phone number for techincal support. 2 hours later it seemed to be fixed. But I mucked up. The call cost me £240 because it was an international number. 
I super pissed that Adobe feel the need to knock out 15 new apps a year rather than keep their existing ones stable. Anyone fancy organising a syncronised month boycott?
