Yes, it is possible to add a timecode to each chapter in an mp4 container.

To do this, you can use the -timecode option in FFmpeg. This option allows you to specify a timecode for each chapter in the mp4 container.

Here is an example command that you can use to add timecodes to each chapter in an mp4 container:

ffmpeg -i input.mp4 -map 0 -c copy -metadata:s:t:0 timecode="00:00:00:00" -timecode_frame_start 0 output.mp4
In this command, the -timecode option is used to specify a timecode for each chapter in the mp4 container. The timecode is specified in the format HH:MM:SS:FF, where HH represents the hours, MM represents the minutes, SS represents the seconds, and FF represents the frames.

In this example, the timecode for each chapter is set to 00:00:00:00, which represents the start of the video. You can adjust this timecode as needed to specify different timecodes for each chapter.

After running this command, the output mp4 container will include timecodes for each chapter, which you can use to navigate the video at specific points in time.
