You're likely doing it correctly but you're using a video format that the browser doesn't understand. Do some research on the Motion JPEG video format and how to display them in a browser, or convert the video to a format that's recognized natively by most browsers.

the video format is mp4. does that not ok?

A video being in MP4 doesn't mean that it can automatically be opened in a browser. You'll need to ensure that the codec is something that can be played in browsers, meaning you'll need to re-encode the video.

MP4 is just a container, not a video format, and the video within it can be one of many different formats. A codec is what's needed to be able to play a video of a given type. Do some research on the difference between a video container, video format and a codec and you'll understand it a bit better.

The first thing to remember is not to confuse MP4 (a container) with MPEG-4 (a video format). They're two separate things and a video with an MP4 extension does not mean it's an MPEG-4 video stream. Your working video is an MP4 container with an MPEG-4 (H264) video stream inside, but your non-working video is an MP4 container with a Motion JPEG stream inside, and your browser doesn't know how to play it.
