Hello,

I am working on a project which involves crossfading between two live video inputs (webcams).
This tutorial explains how to do this with video files, however this method doesn't seem to work when I replace "pix_film" with "pix_video." I am getting an error that the two videos aren't the same dimension..is this possible with GEM?

Hello nlogax

maybe you could use [pix_resize] to make it the same dimension?!

or then, (only now i remembered how i always do it) you could use two render chains with alpha blending.

best,

Johnny

Hey Johnny,

I believe [pix_resize] only works with static images..

Is there any function for resizing video?

thanks

For [pix_video] you can use the [dimen( message. Have a look at the help patch of [pix_video]
