  • What does .mp4.jpg mean?

    What does it mean if a file name ends in .mp4.jpg?

    I have several and they are only an inch wide and when enlarged they are
    very low quality. They were all taken with a Samsung phone model
    SM-A305F in early 2022.

    Is it what it sort of sounds like, a still somehow taken while I was
    videoing something? Or when I was watching the video?

    I don't remember ever doing either of those things, but I have about 100
    of them.

    How would one take a still picture, one "frame", while filming a video
    or watching it? Maybe if I knew how it was done, I'd remember if I did
    it.

    sounds like an mjpeg

    At a guess, it's a thumbnail picture for a video file. Phones do
    thumbnails for photos too. I think it's best to not backup those.

    I may have done it already, but I may find them and delete them. Not difficult.

    I googled, and all I found were instructions of how to convert mp4 to
    jpg. Ah, I forgot to put it in double quotes. That helped get hits, 5
    of them, but they only talked about how to find them, etc. not what they
    were. One guy wanted to play one, so the answer was to rename it
    without .jpg. That's not going to work, and it didn't.

    And I still don't know where they came from, or how I made them.. Oh,
    well.
