I have the problem that when I record multi-camera sequences with my Osmo pocket 3 and the Action 5 and use the DJI Mic 2, the sound is not 100% synchronized. Within a sequence, the sound can differ by one or two frames. This sometimes creates a very unpleasant reverb effect that I can only eliminate by separating the sound track in this area and then moving the corresponding area manually.

Hi there, thank you for your inquiry. We're sorry for the trouble that this has caused. May I confirm if you were using the timecode function when using both the Pocket 3 and the Action 5 Pro? If you are, please note that the DJI Mic does not support timecode synchronization.

Thank you for your support and understanding.

The audio tracks are synchronized manually. They are synchronized at the beginning and then after 5-6 minutes they become asynchronous and at the end they may be synchronized again. The timecode function is not really good. It is very buggy. That is why I don't use it anymore.

I've just done a bit of research into the timecode function of both cameras and I have to say I'm totally disappointed. Because the problem hasn't just been around since the Action 5, it's been around for years. So why is it even mentioned whether you've used the timecode function if it doesn't work at all anyway? Or at least doesn't work well enough to be able to synchronize sound with it?

I have uploaded three audio tracks as an example. The two shorter audio tracks were recorded with the Pocket 3 and the slightly longer audio track was recorded with the Action 5 Pro, each of which had one or two DJI MIC 2s paired. The uploaded audio track is the audio track from the MIC 2. I checked again carefully. It is a small deviation, but such a large deviation that a very unpleasant reverb effect is created. I wouldn't say I have two whole frames as a deviation. But in these three audio tracks there is such a large deviation that a very unpleasant reverb effect is created that I can't eliminate in any other way.

Hi Maddin, we appreciate your cooperation for providing us with the three audio tracks.

During the video recording of action cameras, the clock frequency will jitter slightly, resulting in incomplete alignment of audio and video data. Action 5 Pro and Pocket 3 guarantee the synchronization of audio and video content to the greatest extent by adopting a strategy of aligning the audio with the video, that is, controlling the length difference between audio and video data within 100 ms. Regarding the audio you provided, the length difference between them is within the acceptable range of the camera.

Thank you for your understanding and support.

Conversely, does this mean that synchronization of a 10 minute recording is not guaranteed? Or is it not "better" aligned than the video or audio material that I have available? The reverb effect is really clearly audible. The website advertises that the cameras can even be perfectly synchronized using a timecode. Before I bought the Action 5, I contacted the hotline who confirmed this to me. And now neither the timecode synchronization works nor is the audio data synchronous enough to be processed without errors? What use would multiple microphones be to me if I have to place each carrier in a different room to avoid producing echo or reverb? Is there perhaps a tool with which one can fix the echo or the asynchrony? Or would it perhaps be better to record the sound without a connection to the camera?

I have found a workaround for my problem. In future, I will simply NOT connect the Mic2 to the camera for multicam sequences and start the recording manually. Then I can make a recording with 3 microphones over the entire production period and synchronize them finely at first. After that, I can adapt the video material to the Mic2 audio using the internal audio tracks. In this way, the audio can be synchronized with 99.5% accuracy.
Nevertheless, I find DJI's advertising claim to be extremely misleading. Especially because the timecode function of the cameras does not work. I called German support again yesterday and was again told that there are no known problems with the timecode synchronization and that I should buy an expensive timecode generator. This is precisely the statement that should be avoided and not advised to the already frustrated customer to make a bad investment worth several hundred euros or dollars.
