What one are you using? I'm not gonna use lightbridge. Just your everyday analog video tx. Thanks.
What hdmi to composite converter for your gh4?

I have tried the $120 Kopterworx ones and the $30 "White Boxes" and they all work perfectly. I actually like the "white Box" as the case is easy to mount to stuff.
Avoid the "micro" PAL/NTSC converters as I have never had one actually work with NTSC, the vendors usually just lie about it.
$14... works perfectly:

White box here. Just need to supply 5V to it. Camera can't power it in my experience.

Welcome to MultiRotorForums.com!!
the kopterworx converters were basically a white box unit that was removed from the case and modified to work more easily with our helicopters (wires, connectors, etc.). and they stood behind it if/when one was DOA
some cameras export 5v through the hdmi, some don't. NEX variants do, GH3/4 don't, AFAIK

Thanks guys. So I need a 5v source. I believe the mark ii puts out 5v and so does my immersion vtx

Regarding power from the GH4 HDMI port - I've just heard from AerialPixels, wo sell this unit ( https://aerialpixels.com/shop/hdmi-...-gh4-hdmi-av-converter-micro-hdmi-thin-cable/ ) that the GH4 DOES provide power, at least enough to power their board. But I keep hearing form others, including some on this thread, that the GH4 does NOT provide power though the HDMI out. Can anyone out there confirm that the GH4 provides power through HDMI?

The problem for me is that the HDMI-converter is the only thing on my multirotor that need 5 volts. Everything else runs just fine on 14.8 volt (even though they claim 12 volt), but not that one.

Good point, only avoid the micro one if you nee NTSC.
PAL guys, you are lucky!

Getting nowhere with the gh4 and the magic white box. The gh4 shows on my TV when hooked via hdmi but nothing is transmitting thru the white box to my immersion vtx. Little frustrated

What frame rate? Sometimes you have to start in a lower frame rate to get the converter to "start up" and then you can change it after it's fired up. This is the case on my BMPCC enemies.

I've tried 24, 30, 60.

I've ordered the kopterworx one with the immersion harness. Yes it's expensive but it will work or they will stand behind it.

First of all, your avatar is really freaky. Lol
Could you kindly share you camera settings?
Thanks

Er... gimme a list... I'm not the camera guy. I just plugged it in and it worked, I'm getting all the wiring cleaned up and prettying everything up while the actual camera guy is working another job

Welcome to MultiRotorForums.com!!
aren't you contradicting yourself? you say no power needed but then say plug it in via a servo connector for power.
i'm confused.

No, I set it up so that if I did need power (on some other camera for example), I can just plug in a servo connector I spliced in. The GH4 apparently doesn't need it as it worked just fine without it.
We're using an external power source instead of the internal battery though, I don't know if that would make a difference.
