Video Freezes, OSD still working -> Wrong VTX Tables
#1
Question 
So I was just flying around in a small park, hiding under some trees when suddenly the video decided to just freeze up during a tree jumpy move. I was not going full throttle as you can see by the AMPS on my OSD, which was still online so transmission from VTX to RX was fine..

-Update: I was using the wrong VTX tables. Label 800 in Betaflight needed to get value 600, and not value 800 which I was sending to the VTX. Guess that messed it up somehow.


Video did not come back until I unplugged and repowered the quad.
After the crash I lowered the power output of my VTX to 400MW from 800MW. (Which are both a bit overkill for nearby flying)
The second flight and final flight went without anymore problems. But it got me freaked out.

See the video here:

Luckily I was able to shift to angle mode and land it LOS from a distance without crashing too hard. (I suck at LOS)
Sadly I forgot to turn on the GoPro for some pretty crash footage..

Does anyone have any idea what could have caused it?

I've checked all cables and this frame has a stock capacitor on it, could it have been the 800MW output power that was pulling power from the camera or maybe asking too much from the FC.. just guessing.

Nazgul 5 Analog v2
The VTX: IFlight Succex Force 5.8
Camera: Stock IFlight RaceCam

I vaguely recall someone having a similar issue that turned out to be a bad internal connection in the cam.

I think it’d kinda have to be something in the cam, because neither the osd chip nor your vtx are storing any image. Osd is just overlaying the osd, and vtx is just transmitting whatever is sent to it.

Good save, btw.
Dangerous operations.

I wish I could get the smell of burnt electronics out of my nose.

Thanks, yes I'm also thinking its the camera since the picture froze but didn't go black..
If it happens again I'm gonna swap that first.. maybe I should take it apart and have a whiff..  Thinking

I wouldn't wait. Imagine you lose picture while flying and it comes down and hits someone. Cameras are a cheap part. Just replace it and put the broken one on something else that is maybe less powerful or you don't mind wrecking.
