There are two things I want to add to my current intermediate DVD
mpg video files created with ffmpeg, and/or to the DVD tree
structure created with DeVeDeNG:
1. Create and add a Navigation menu in the beginning
This will be an upcoming, separate topic
2. Create and add Soft Subtitles as simple text info commentaries
to the video content
This is the topic for this post.
The reason that I want Soft Subtitles as a separate text
file stream related to timing, is because this should be possible to
add or import to an existing video file without the need to
re-encode. It should also be flexible to display on or off during
playback, if I have understood this correct so far.
2.1 Preferably I want to add/import subtitles as fast and easy using
GUI interactive tools like DeVeDeNG or VLC if possible?
Next thereafter could be using the more time consuming ffmpeg

2.2 So is the question if learning a special subtitle editor is
necessary to create the text file easier, like one of these 5

Tip, suggestions or experience how to do this?
