"I'm trying to play a video file from 2022, but it won't load. It's a standard MP4. Does anyone know if this naming convention is specific to a certain phone (like Samsung or Huawei) or if I need a specific codec?"
Finding a video with a generic filename like can be tricky because it doesn't describe the content; it just records the date (October 11, 2022) and time (10:14:07 PM) it was created.
If you have the file but don't know what's in it without watching, you can:
Right-click the file and select Properties > Details (on Windows) to see the exact creation date and possibly the device used.
