No, an MP4 video file cannot have a transparent background.
Never mind, I got it, you need to use a clipping mask (Detect edges)
To create a video with a transparent background in After Effects, you can use the alpha channel feature. This involves rendering your video with an alpha channel enabled, which allows the background to be transparent. You can then export the video in a format that supports transparency, such as QuickTime with the Animation codec or PNG sequence.
In the CSS for your element, you need to enter {background-color:transparent;} You might also need {background-image:none} depending on what's going on already. If you want to add a semi-transparent background, a PNG with the alpha channel saved is your best bet. Then just use the background-image declaration.
Convert it to a format that does not support transparency (for example jpeg) or use a tool to edit the transparent pixel value.

- Open "Edit Profile" - Select "Customize" - At Customize CSS just fill this :body { background-image: url(your image url); background-attachment: fixed; background-position: top center; background-repeat: no-repeat; background-color: transparent; cursor: ; } example :body { background-image: url(http:/www.de-angel.com/Friendster/FS.GIF); background-attachment: fixed; background-position: top center; background-repeat: no-repeat; background-color: transparent; cursor: ; }
The best way to export a video with a transparent background is to use a video editing software that supports alpha channel transparency, such as Adobe After Effects or Final Cut Pro. You can then export the video in a format that supports transparency, such as the QuickTime Animation codec or the WebM format.
