No video watermark mods and default doesn't work?

Anyone anyone?

There use to be a few in the market; possible that they were not upgraded for 7.3.3 and Boonex, stupidly I may add, remove them from the Market listings.  I was quite vocal on the Market changes but I am nobody and the king makes the decisions.

Watermark modules are in the market, please try to search for "Watermark":

These are all for photos, judging by the titles and descriptions. I need for photos and videos. 

Do you want it for every frame of the video?  Dolphin uses FFMPEG to encode videos that are uploaded to the site (for embedded videos it only creates the thumbnail).  If you don't have the skills to do this, then PM me as I am available for hire.

I think I wouldn't need it for video if the player had an easy way to turn off downloading.

You can turn off downloading.  Of course the only ones that could not grab a video on your site would be those without the knowledge.  I can grab any video off of any site on the web.  If this is a matter of copyright, then yes, you need to watermark each frame of the video so that even if someone does steal the video and reuses it, it has your logo on it.
