for several languages at once you need to use map: ffmpeg -i input.mp4 -i input1.srt -i input2.srt -strict -2 -c copy -c:s mov_text -map 0 -map 1 -metadata:s:s:0 language=lang1 -map 2 -metadata:s:s:1 language=lang2 output.mp4

srt fixer gui

SRT Fixer is a simple Python-based tool that processes and fixes issues with SRT subtitle files. The tool removes duplicate lines and corrects timing issues in SRT files, which are common problems in YouTube's automatically generated subtitles. The application is built using Python's Tkinter library for an easy-to-use graphical user interface.

• Fix duplicate lines in subtitle files
• Correct overlapping timings
• Process single files or an entire folder of SRT files
