My three things today

Issues with monitoring with the GH4. Basically you switch from .mov to AVCHD recording and back again if it's not outputting video via HDMI.
Apple's Time Machine can get cranky about disk permissions. Just. Because.
Panasonic's VLOG-L is very interesting. I don't know why Panasonic is so weird about releasing it. It's a $99 upgrade but it's frequently "out of stock". I mean it's a flippin' serial number for a software upgrade and it's... "out of stock". Nobody knows why.

There are some complications using VLOG-L. One is that it doesn't really work in 8-bit as nicely as you'd like. And that's what the GH4 records internally.
