So I can send a down sampled 4K signal out of the camera into a $300 Atomos Ninja Star. Exactly the same results, just before editing, and it secures 10-bit 422 color. No brainer.
I had the same idea, and found a great deal on a barely used Ninja Star on Craigs List. There are a couple of annoying inconveniences with this gear, though. You cant trigger the ninja star by pressing the GH4 shutter button--you have to press the Record button on the NS (Atomos enables GH4 triggering on their more expensive gear but are dragging their feet on a similar firmware update for the NS). Also, you cant play back footage on the GH4's built in display; you have to hook the NS up to an external monitor. And you cant simultaneously record 4:2:2 10-bit footage to the NS and 8-bit 4k footage to the camera's SD card.
When and if the Black Magic Video Assist monitor/recorder comes out, i may trade up to that, which will solve the first two problems i mentioned (but not the third, because that's a limitation of the GH4).
