Adding a watermark-Avid Liquid 7
 

Hi again,

Now another question :
I want to add either a watermark/copyright notice on the raw footage-I work with Avid Liquid 7 -do you have any idea if I can do this with Avid ?!...or maybe another trick that works with Avid Liquid.
Thank you guys.

Use a track matte is one. You can create an alpha channelled video with a white font that will show through IIRC. Or use a tool such as Photoshop, etc., to create a text with alpha so that most of your text is alpha. Import and drop above your video.

Or just use Deko to create a title to watermark. Use Opacity in Deko to get it very faint as you wish.
