A. Yes but how you do this does depend on your phone.

Some phones will let you transmit these video clips directly from the phone via MMS, others by email. If your phone can do this just send the MMS or email with the video attached as described here.

Some phones cannot send files directly and you will need to firstly transfer the file to a PC by infrared or Bluetooth. If you do not know how to do this, consult the manual that was delivered with your phone. You can then use the 'Create File' command from the 'Create a new item' function to upload the file from the location where you saved it on your PC.

Some phones that support video clips store these files in a special file format. Some Nokia phones, for example the Nokia 3650, store sounds, images and multimedia messages in the *.3gp file format. In order to be able to play files posted to your site, the PC viewing the site will need to have a compatible player installed. One such player is the Nokia Multimedia Player available from Nokia.
