How do I embed an mp4 video in a text box?
MP4 videos can embed in a text box using the Rich Text Editor. Other file types that can be embedded in a text box are .FLA, .F4V, .3GPP, .M4V or .MOV files.
This displays an upload file dialog box.
Once you have located and selected the file, click Open to upload it.
Once the file has finished uploading, it will appear in Resources and will be selected by default. Click OK to add the video to the Rich Text Editor.
