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.

IIRC you can't add text-based subtitles to DVD video. Blu-ray yes, dvd no (both can use palletized reduced-color graphical subtitles) ... so at least rendering text as palletized picture and then muxing it into mpeg stream is unavoidable step,as far as I understand.

But may be those DVD creation guis can do srt => dvd_sub conversion for you ?

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?
