ATEM1 input questions

Hy there,
i cant find anywhere answer to my question...

ATEM1 has 4 HDMI and 4 SDI inputs...

I want to know is that total of 8 inputs at once, or i can use HDMI or SDI in same time?

Is it possible to mix input resolution signals?

All inputs can be active.

You cannot mix resolutions/frame rates. Everything must be running in the exact same format the ATEM 1ME is configured to run in.

what about hdmi and sdi outputs?
same resolution as well or?

Yeah... when I say "EVERYTHING" that means everything (HDMI and SDI) including the outputs. The exception is that on the 1ME it also has SD-SDI and Composite SD outputs. Those are always automatically down-converted.

i know this wasn't the question but you can also use the component out at the same time ...

so if in hd that is hd-sdi, hdmi, hd component, sd-sdi, and composite ... which will all match the set resolution of the switcher... obviously the sd-sdi and composite will be a down-converted version of the hd signal.

When you connect, for instance, 4 camera's with HDMI and 4 camera's with HD/SD and all are set to the same output, say 1080i50. If the ATEM1 is also set to 1080i50 you will be able to switch 8 camera's.
I did it like that. These days, caused by the limitation of the HDMi cables, we only use camera's with HD/SD outputs and have 4 mini convertors to change just in front of the ATEM1, 4 of these signals to HDMI. Also a great way of splitting picture from sound to use the sound apart for mixing purposes.
