Yes you can!

In Elxis you can incorporate video inside your content as part of it. To do so, you have to use the {mosflv} mambot. Below the editor you will find a special [F] button.

Place the cursor where you want the video to appear and press it. Automatically a new line like the next one, is placed.

{mosflv}path_to_flv_video.flv{/mosflv}

All you have to do is replace the "path_to_flv_video.flv" with the path to your video file. Elxis supports .flv format video files.
