Convert M4S to MP4

M4S file

M4S files are MPEG-DASH (Dynamic Adaptive Streaming over HTTP) video streaming segments. These files contain a fragment of video data, and they're typically combined with other segments to form a complete video. M4S is not a standalone video format and usually needs to be merged or integrated into a more standard format like MP4.

MP4 file

MP4 is a widely used digital multimedia container format. It stores video, audio, and other media. Known for its compatibility with numerous devices and players, MP4 is a preferred format for storing and sharing videos.

M4S to MP4 conversion

The m4s to mp4 conversion is related to attempts to convert video segments (.m4s) to the standard .mp4 video file format. This should certainly be doable, but some users report that some data might be lost by doing so. FFmpeg (a powerful command-line multimedia framework)and perhaps other similar video converters should work.

1. First, the individual M4S files must be combined into a single file (if multiple). This is typically done using a concatenation command.
2. Try the following command: ffmpeg -i "input.m4s" -c copy output.mp4 (replacing input.m4s with your file's name).
