Thanks David. Is there anyway you can simulate some wind noise maybe with a desk top fan? This way we can see if the reports of clipping are due to the microphone versus the adapter.
I believe the Osmo turns off wind noise reduction when using the Cynova adapter, which would also explain this..

Alright Matt.
I will be doing a full review of the setup soon, I'm just waiting for the deadcat for the NTG to try proper wind stuff.
I suspect that the issue you are talking about may well be a combination of things but highly likely to be exasperated by the dynamics processing between the Cynova and the Action.
In my tests I have full control of the level going into the Cynova and regardless of the level, low or high, the Cynova/Action will still use dynamic processing, most notably AGC (automatic gain control) which in combination with the limiting can cause low frequencies to sound quite hot.
The sound of the NTG in this test is very influenced by the Cynova/Action, it does sound different and better on the GoPro 8 with the GP mic interface.
Certain mics will actually sound better on the Cynova/Action compared to other mics, where on another camera the differences may not be as much. I also suspect that the impedance and sensitivity of any given microphone is going to effect the quality of the audio on the Cynova/Action compared to other cameras/systems.
In a nutshell. The Cynova/Action still needs a fair bit of work and I also suspect that there's manufacturing discrepancies to contend with as well with the Cynova. There's far too many reports of wide variations with the use of the Cynova.
BTW. I've done that before and after firmware test, I'll post it sson.

Sounds good amigo! I don’t suppose you have an old school (one w/no gain/level adjustments) low tech Omni-directional laying around that you can throw into the mix. If so, I’d be curious to see if the default levels of a non-adjustable mic are clipping for you. I even put a dead cat on the Eutige ETM-001 and the audio was TERRIBLE/unusable (in the cab of my Raptor with only the windows down - so not even directly in wind)
I might have to break down and buy that Rode wireless go, which (much like your NTG) can be toned down. So for now I’m relegated to on board mic only, until I can get my greasy palms on a Rode wireless go.

Hi Matt.
I've just been sent three mics by Neewer and one by Comica for reviews. Although these are cardiods they are fixed gain with various sensitivities and impedances, I'll check these out.
I also build a few small mics and lavs which are omnis with a very sensitive and loud capsule, these will drive the input properly and may be a good gauge.
It's also worth bearing mind that while the omnis I have are more sensitive and louder than the cardioids, cardioids are naturally more sensitive to wind and plosives. It could be this particular characteristic of the cardioids that's part of the issue.
I'll try and get round to this stuff soon but I'm trying to catch up on a bunch of videos and plan for a bunch of product reviews. I can feel a big dump of videos coming on for TouTube soon to get me back to a clean slate for the new year
BTW. Here's that before and after video, I'll post this as a new thread on the forum soon, I'm just catching up with thumbnails and descriptions etc. before I put a bunch of them live. You may also notice that this sounds very impressive on the Cynova/Action after the cable pull, Matman Method and after the update. This particular mic sounds great on anything, it's a Sennheiser ME64 it's my main dialogue mic and the one that I use for all my indoor stuff when I'm at the table or reviewing etc. You get a name check

David, have you tried using the microphone USB-C to USB-C, eliminating the adapter?
Hi.
I’ve tried, it does not work. For this to work the Action’s USB-C interface and processor/software would have to be Class Compliant.
If DJI were to do a firmware upgrade and make the Action or even the Pocket’s USB system Class Compliant, then you could also plug in many other devices such as USB audio interfaces. This would then open up the possibilities of using many different microphones and a large number of interfaces.
It’s just a real shame that companies such as DJI and GoPro, don’t give the users of their cameras the freedom and flexibility to choose their own interfaces. Instead, we are always tied into a closed loop where we have very little choice but to use the peripherals that are supplied by the manufacturer. In the case of DJI this is especially frustrating as their offering for the interface for the Action is especially poor quality.
Let’s hope that when we get to the next iterations of the Action and the Pocket that we are given the choice to use a standard that the whole world of computing has adopted and that we are not once again tied into high priced, inferior and massively limited interface options.
