Hi!

I want to know why can be that if i move from 720p25 project to 1080p25, when i change the setup of my camera, the image works for a few seconds and then just freeze.
You can see here the test:

If i reset the input, the image appears again. But after a few seconds, freezes again.
I work with a Blackmagic Deckling, getting video from HDMI.
In 720p25 works fine.
Using last vMix version.
Thanks!

your camera aspect ratio and frame rate needs to match the project aspect ratio and frame rate

Thanks for answering.
Thats not true at all. Its true that same aspect ratio and frame size and rate helps a lot with CPU and GPU usage but one of all vMix advantages is that you can use multiple sources with different frame rates and sizes.
In the other hand, you can see that vMix get the camera. A few seconds later just freezes.
Thanks! And sorry for my english. Im writing from cellphone with spanish correction.
Regards

Just a guess, but your graphics card is probably the culprit/

In my experience Blackmagic's devices demand that you specify the exakt camera resolution and frame rate in the Input. Other cards (eg Magewells's) automatically adapts if the settings are changed in the camera.
