Pipet and CPU

For my LEDwall I was thinking about using the Pipet node on some pictures, so it looks like the wall is ‘hoovering’ above them.

I already found out that CPU load is very heavy with 360 spreads(60x6 pixels)

Now I was wondering if it was lower if I use a 16 or 2 color picture, in stead of a 24bit picture. Also, does the type off compression have any thing to do with that?

In theory I only need a black and white poicture to show crazy stuff.

Some lights on my dark path are more than welcome.
