I just found out about an amazing web application somehow related to graffiti.
We can now draw over an YouTube video!
Here’s how it goes. Select the YouTube video you want to modify the copy the address from your browser. Paste this address on top of the application page, just below the Graffiti VIDAVEE logo then press LOAD. The YouTube video will be loaded. Play the video and stop it where you want to draw over it. Then click on the drop-down menu from the right side, choose an effect and drag it over the YouTube video. You can resize and move the effect to match your needs. That’s it :) Nothing more.
Here is the original video (how it looks on YouTube):
And here is the modified video from Graffiti VIDAVEE application:
