Panasonic FZ1000 4K sample on YouTube

This is the 4K sample I shot on the FZ1000. Unedited and straight off the camera. I can't currently watch it in 4K on my system, it keeps stuttering. YouTube lets you choose how to play it back, so I thought it the best way to show the quality. Let me know how it looks. (Please note I didn't set up anything, just selected 4K and pressed the red button, so bear that in mind.)
