Create MP4 or another playable video format from frame series of JPEG in a directory

So I have frame series of JPEG in a folder let's say folder cctv where inside of that folder is only series of JPEG with unix timestamp named in nanosecond. I mean like this ( I used tail because too much to display).

.../uwc/cctv $ ls | tail

I can display MJPEG from those series with OpenCV or Flask, but idk how to convert it to mp4. I expect I can convert those series to mp4 with specifying frame rates I want for example 60 FPS. So how do I achieve it? I suspect ffmpeg can do it, but I never use so I don't know how to use it, maybe this will be my first time to use it. Actually MJPEG is fine and playable in VLC but it will burden layman like entering URL stream of those JPEG or maybe need opening web browser. And ofcourse I don't need audio.
