Interesting thread chaps. Thanks, just read through the whole lot! I really hope the next Panasonic FW release sorts the 16:9 12MP thing.
I have had the "white out" issue several times. Sometimes wire wiggling solves it, sometimes not. Today my gimbal dropped right about 10 degrees in flight for no obvious reason. Gimbal consistently boots a couple of degrees off horizon.
Video is superb even without ND but I think I will get one after reading this. I still have a lot to learn on the camera side of things!

I've just bought an ND so I'll let you know how that goes!

Yesterday I took the s900 out for some proper test flights, conditions were good and fairly calm. At last I got 3 flights in and the camera and zen worked fine, but I did get a few screen hiccups on powering up, then the image settled and stayed good. The footage looks great, I did get some vibration on a fast forward climb and a lot of horizon roll on fast panning (you wouldn't pan that fast when filming, but still a bit disappointing). The 4K footage looks amazing, but I've got to hook up some thunderbolt drives to cope with it, firewire 800 seems too slow...

Good thing. I did it too. (I can confirm now that fn1 to wifi was cutting off the transmission when hit during initialisation. )

My first GH4 gimbal did that. I sent it back for that plus I had no composite video output. The second GH4 gimbal did not have the roll when panning issue. I just finished up a project where there was a lot of aggressive flying and following in a car chase scene. The first gimbal would have been a problem.

Hmmm, have I got one of the same batch? Should I send it back? Here's a quick low res clip of a pan. Can it be adjusted in any way? I flew forward only, the camera operator panned the camera. He had done a pan in the other direction as I got into position for a fast run. The gimbal levelled off very gradually after the rolls and had been level on take off.
Jumpy are you talking about the HD/AV board or the GCU?

Latest issue for me- turn cam to 4k 25p and live view disappears no matter what the down convert is set to!

I mentioned this before but the only way for me to get 23.98p or 24p is to handshake the camera in 29.97 first (at 59.94 system frequency), THEN change the camera to the desired frame rate. Any other way doesn't work. Of course this is a total pain since when landing to swap batteries it adds 5 minutes to the process as I have to go in to the camera menu several times, reboot, etc. I've resorted to hot swapping the batteries (duals) one at a time to keep everything going. And that's not to mention I'm stuck in PAL for analog output to the VTX.
I'm tired and frustrated with DJI's lack of attention to the voluminous amounts of problems with their gimbals. The only reason I have remotely working setups is because of the support I get here in the forums. I can't wait to see what happens when the new GH4 firmware comes out.. we'll probably all have dead gimbals since God forbid DJI gets ahead of the issue by working with Panasonic.

Ah I do remember this now. What a pain. I nearly always initialise with the camera already switched on and the resolution set to 1080p 60fps and then change from there.
Today when I swapped to 4k with everything initialised I lost my live view. I'm on NTSC.

Right just had a desktop fiddle. With the GH4 turned on the gimbal initialises in 1080p record format at any frame rate. As soon as I switch the resolution to 4k no matter what the frame rate i lose live view. Switch back to FHD and the live view returns. This is in NTSC with the HDMI record output set to off or 1080p. I have fiddled wight he down convert setting and this makes no sense.
As it stands I cannot fly the GH4 and record 4k!! It's not been an issue before as clients have only wanted FHD at 200mb.

NTSC? I use PAL and everything works, including 4K. I have HDMI set to 1080p constant. No down convert or auto.

Will try it on PAL tomorrow Ben.
