>Create and add Soft Subtitles as simple text info commentaries to the video content

This is the topic for this post.

Hello, Terje. You can try to use ML and machine learning approach to do this. Use whisper.cpp (https://github.com/ggerganov/whisper.cpp) program to generate srt file from your speech. The program itself is really small, but you'll have to download relative big pretrained model. I use it myself, then I need to convert my dictaphone record to text. To convert srt to vob, the srt2vobsub program can be used.

I think that separate third party plugin can be made for cin-gg to automate this.

Best regards,

Andrey

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.

I have prepared a new video file and will try to add sub-titles to-morrow

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?
