Dash cams typically record videos in various formats, with MP4 being among the most common due to its wide compatibility and efficient compression. This format is easy to store, transfer, and view on numerous devices, making it ideal for quick sharing and viewing of dash cam footage.

However, some dash cams offer support for alternative formats like TS (Transport Stream). While not as common in dash cams, TS is designed for reliable media streaming and can be resilient to data loss.
