Are my Videos traceable?

I am basically screen recording short videos of graphics of a cool software - basically they portray dynamic landscapes - rivers moving, wind swaying trees, Birdseye geographical movement etc.

I have moved all the topical illustrations they added so that they appear to be generic animations.

I plan to use these as the background to some webpages.

My question is - using any metadata or other analytical skill I'm not aware of, can anyone potentially copy and trace these graphics back to the company who published or helped to make them?

OK, Thanks

Just to add - I used quicktime player, everything encoding etc is just ordinary - .mov AAC etc (some of them have musical themes)
