To help you identify what's in the video, here are the most common contexts where filenames like this appear:

: If the numbers follow a standard date format, "02-13-04" likely refers to February 13, 2004 , or a specific site/camera coordinate system.

: If you found this file on a USB drive or SD card, plug it into a computer and open it with a media player like VLC Media Player , which supports .m4v files.
