Responsive video

Hello,

I need some tips please to insert responsive video. If necesary, I could create 2 videos, maybe for big screen and another for mobil screen. With generateblocks it´s easy to hide the blocks in responsive.

I would appretiate some tips.

And also, I´m looking for a video online edition tools where you can insert logo, create animation with them (zoom in, zoom out). Or may be better with some events from generateblocks over the video. Is it possible to insert the video like a background image and then the logo above?

Thanks a lote
Angel
