If you have VLC media player, open the video and pause it, then go to Media Information; alternatively, you can use a keyboard shortcut of CTRL+I

When a new window opens, you will have a wide range of metadata which you can edit. When done, simply click on the Save Metadata button. And another note, please be patient while the tags are being written, this may take some time depending on the filesize of the clips. Try not to poke the program and crash it while it writes the metadata.
