The reason why your action camera generates multiple files when shooting a video may be due to the following reasons:

Our camera operating systems limit the size of single files: SD cards formatted with the FAT32 file system only support a maximum of 4GB for a single file. Therefore, the action camera needs to split the recorded video into multiple files to avoid exceeding this limit.

Please check if you turn on the loop record function.
Using Loop Recording, you can continuously record videos, but save only the moments that you want. For example, if you select a 5-minute interval, only the previous 5 minutes are saved when you press the OK button to stop recording.
If you record for 5 minutes and do not press the OK button to stop recording and save, the camera records a new 5-minute interval by recording over your previous 5 minutes of footage. When the memory card is full, the new files will cover the old ones if the loop recording is on.
