Read the requirements on top. You can only upload a video up to 20 MB. Once you found your video you can also choose the album in which the video should move. If you do not select an album the video will move to your generic photo folder. Hit save.

Go into "My shots" and find the video you want to edit. On the left navigation find t "Edit shot". Click it to open a new window where you can change the title, tags and give it a description. Hit save. In order to delete a video you also have to find the video first. On the left navigation find "Delete shot". Once you hit that button your video will be deleted straight away. You will get a confirmation for that in a yellow layer, which you can close.
