Does anyone have a 4K video clip you could share with me for some testing?

Much appreciated.

Why don't you download the Vmix 4k Funtime show from this Month?

James - I downloaded the October VFTLS and it did not d/l in 4K. Must be a limitation of the d/l app I used. But your link to the 4K samples was perfect. Thank you!

I'm testing just how much bandwidth 4K uses over NDI. I'm getting 180-200Mbps for 4K @30 fps. That seems low. I was thinking it would be closer to 400Mbps or even more. Can anyone comment?

Thanks.

The values are you seeing sound about right when I compare to some data that I've got.
