Special considerations for image and video files:

  • For .psd files, we recommend saving your files with the preference to maximize compatibility.
  • Video codec created via GoToMeeting can be previewed.
  • When you save a video in your Dropbox you will be able to watch the full video from a preview page.
    • If a Dropbox Business user creates a shared link to a video, the recipient can view the entire video on a preview page. This does not apply to videos created by users on a Dropbox Business trial.
    • If a Dropbox Basic, Plus, or Business trial user creates a shared link to a video, the recipient can only view up to 15 minutes on a preview page. Recipients can download the file to their computer or add it to their own Dropbox account to view the entire video.
