DJI OSMO Action, the new-comer of the action camera family, comes with a number of amazing features and brings a lot of fun to the users. But there are some tiny or seriously nerve-wrecking problems, according to our personal 4K editing experience and the the feedbacks collected from forums.

But here we provide you with an easy solution. This is a complete guide on how to split DJI video files without audio and video out of sync. If you run into the error after splitting video in DJI OSMO Action camera, check the following guide.

Audio Is Out of Sync with Video After Splitting in DJI?

DJI OSMO Action Camera

This issue was firstly found by an OSMO Action user named David_Harry, who posted it on the DJI forum. He tried the camera built-in split feature to cut a 4GB video into multiple files. But got the result of audio of some files goes out of sync with the video.

We thought it would be the same as the OSMO Pocket issue, for the Pocket also had audio gap issue. But as digging the issue deep, it seems that they are totally different.

As for the Pocket, the audio goes later than the video. Or simply put, there is a passage of audio missing from the start of the video. While about the Action audio/video syncing issue, the audio runs ahead of the video. There is a passage of video lost from the start of the audio. Besides, in the second file, we cannot find the missing audio file.

Another much more interesting thing is that when we watch the clip directly on the OSMO itself, it plays in one continuous stream, and the audio stays synced. So it possibly has something to do with the video latency issue. But how to fix it?
