Issue Description

The sound of tapping on the screen can be heard only after 3-4 frames following the picture showing that the user tapped on the screen, as shown in the figure.

* The video specifications are 4K/100fps.

Solutions

Because the audio signal of the wireless microphone needs to go through several links such as collection, wireless transmission, signal processing, and coding and packaging, there may be a minor delay.
When a video is recorded at a normal frame rate, the audio delay may be optimized to the effect that is almost the same as the view quality and will not affect the audio-visual experience. However, when the recording frame rate is higher, such as at 100fps, the audio delay may be more obvious. Please refer to the recommendations below:
1. If possible, we recommend that you decrease the frame rate to 60fps and below to obtain a better synchronous effect of the soundtrack and picture.
2. If the shooting frame rate cannot be decreased, we recommend that you align the soundtrack through later processing.

If the issue persists after the above solutions have been tried, please contact DJI Support for further help.
