Hello everybody.

I've got maybe a total beginner question, but I really wonder when I want to project my video on a wide canvas (using multiple projectors) what format should my video be in, in order to fit the canvas perfectly? does it depend on the projection canvas format?

And is there any easy software to make a soft edge blending?

Thank you very much for your answer

Edge blending tends to be extremely expensive to perform and you have significant issues with desktop overlays. I've yet to see a version of this which is anywhere near 'beginner'. Typically, multiple projectors are butted up edge to edge to make things close.

It should be kept in mind that every projector tends to have a different color balance, and that lamps age differently which shifts the color balance, so constant calibration is a requirement.

There are some PC solutions now which can use a digital SLR camera connected to software which can balance color and correct edge blending solutions pretty much automatically. They are a LONG way from inexpensive.

Thank you for your answer!

And what do you think of this? Is this also expensive or low quality?

Can somebody comment on the video format as well?

Thanks!
