Atem television studio media from pc

Good afternoon everyone! im making an online stream with the atem television studio and a matrox, the problem is that i need to pass videos before the streaming, the videos i have are h264 from my pc, how can i make this possible?

Ps. i have tried with a decklink mini monitor with an sdi but media express dont want to send 1080p 29.97fps. (and media express only wants avi and quicktime mov videos that are extremely heavy)

thanks everyone!

Hello Andres. You could consider playing the H.264 files using your PC media player and connect HDMI to the ATEM. You didn't mention which ATEM but this might work as long as you match the HDMI output to the ATEM.
