Does the New DJI Mic Have a Sound Trouble?

I lastly been given my DJI Mic right after pre-purchasing it more than a month in the past, and at 1st, I was unhappy. When I did the initial take a look at with the DJI Receiver connected to my Canon R5, the audio I recorded was substantially noisier than what I was utilized to from my outdated setup, for which I utilised a Zoom H1 with a Rode Lavalier GO. But there’s a option to this trouble, and in this posting, I share it with you.

First thing’s 1st: this is not a full overview of the microphone. I did not have it extended more than enough. When I purchase new products, I make absolutely sure with a set of initial checks that it performs adequately and does what I want it to do. If it does not, I send out it back again within the return time period. And to be sincere, that’s what I imagined I might have to do with the DJI Mic just after listening to the first recording. But as you can before long find out, the noise resulted from the erroneous settings in each microphone and digicam. The DJI Mic can provide very good audio top quality if utilised properly.

Recording a Backup Monitor

The 1st point I did to determine the dilemma was history a backup monitor directly to just one of the transmitters. It is a useful element that I will use a ton. The transmitter has a focused file button that begins the backup recording independently of the digicam recording. With it, I can possibly record a backup keep track of in addition to the audio that goes into the digicam through the receiver, or I can use it as my stand-by itself audio recording resolution when filming with the GoPro.

So how did the backup recording sound? I am happy to say that there was no audible sounds existing, which tells me that the sound in my prior recording was launched somewhere in the transmission chain among the transmitter, the receiver, and the camera. You can pay attention to this significantly enhanced audio sign in the next segment of the element online video.

At the time I opened the WAV file of the backup observe in DaVinci Resolve, I found a lower audio degree. I had to intensify it by additional than 16db to align it with the audio I had recorded on camera right before. Because this backup audio signal is pretty clean, intensifying it in post-manufacturing did not introduce any sounds.

It tells me that through my very first examination, the audio signal need to have been intensified by a related volume within the digital camera due to the fact I had not utilized any other gains in the DJI Mic. Considering that the audio signal going into the camera is by now a decoded analog sign, any noise that’s released now is intensified as the camera boosts the audio signal.

Implementing Get in Transmitter and Receiver

In the DJI Mic, you can established the gain in the two receiver and transmitter independently to values in between -12db and +12db. You should really adjust the transmitter attain to a benefit, which effects in a robust audio signal that does not clip. On the receiver, there’s a degree indicator, which allows to great-tune this location. You can also improve the audio signal in the receiver itself by applying an more acquire ahead of it goes into the digital camera. Though owning the microphone related to the Canon R5 and my Dell XPS, I discovered that I should raise the signal significantly to prevent sound.

The later in the audio chain the audio sign is intensified, the more noise you get. The worst factor you can do is established the audio ranges in the digicam to car and the gains in the DJI Mic to a reduced worth. The camera will then raise the audio stage with all the sounds that is introduced together the way. That’s what transpired in my initially examination when I had every thing established to default. You can listen to it in the first part of the element online video.

I’m however experimenting with unique settings, but what works for me now in an place of work set up without having any ambient sounds are the adhering to configurations:

  • I set the attain in the transmitter to +6db

  • In the receiver, I apply +3db

  • I manage the audio amount in the camera manually and established it to a benefit of 50% or significantly less

It results in an audio sign of equivalent depth as in my initial exam but with a great deal fewer sounds.

Now, I really encourage you to do your assessments and fantastic-tune people configurations to what will work for you. I will also consider to further more enhance the audio by experimenting with the gains. But I felt that it is crucial to share this now so the facts is out there and you happen to be not as puzzled as I was in the starting. If you movie a whole lot, this is definitely practically nothing new for you. But for me, you will find even now a great deal to find out when it arrives to audio and online video recording.

How to Synchronize Audio and Video

Since the backup recording sounds so very good, you may want to generally document it in addition to the audio you record on camera. If you someway mess up the attain options, and the audio sign recorded with the video clip will get as well noisy or clips, you can trade it versus the backup track.

In fashionable video clip modifying computer software, synchronizing audio and video clip is uncomplicated. As an example, I want to share how to do it in the no cost software program DaVinci Solve. Right before dragging the movie and audio clips into the timeline, pick each in DaVinci’s file explorer, ideal-simply click on a person of the information, and pick out “Vehicle Sync Audio – Based mostly on Waveform”. It will get the job done flawlessly for the backup keep track of simply because the audio resource is similar to the audio in the video file. The only discrepancies are depth and sounds stage.

To stay away from confusion as you report a lot of online video and audio clips, ensure that the time and day settings in both equally the camera and the DJI Mic are the exact. In DaVinci Take care of, you can then buy the files dependent on their generation time, which will make it substantially much easier to find corresponding tracks.

Lastly, let’s hear your experiences. Do you also have a DJI Mic or a very similar microphone? What configurations perform best for you?
