Photoshop 2022 won't open mp4 files

[Steve24840025e7el]

I recently have a new Dell laptop and since then I cannot open mp4 files with photoshop 2022. I did use media encoder and converted the file from mp4 to quicktime file. Afterwards, I could open in the new format. Any ideas on why the mp4 files won't open?

The mp4 files in question, do they open in other applications on your computer? Is it just Photoshop where they don't open?

Hi and thanks for the question. Yes, other applications were able to open the MP4 files. I made this video on July 23 using a GoPro 10 with higher quality video settings and slower frame rate (not sure if that matters yet but see this next paragraph)...

Last night, I was able to open an older MP4 file from last December. Photoshop opened that file but could not open the MP4 of July 23. Again, other applications opened the July 23 video. The main differences of the file are frame rate and size. I made a comparison of the file properties uploaded below. I could not upload the video due to the size. 

Thanks for your question again!
