Choose the output before editing
Use SRT or VTT when another editor or player needs timed text. Use TXT when someone needs the words without display times. Use a captioned MP4 when subtitles must remain visible in the picture. These outputs solve different jobs; changing a filename extension does not convert between them.
SRT and VTT keep a timeline
A subtitle file contains text and start/end times, not the video itself. Keep the original video beside it and check which format the destination accepts. Use the SRT/VTT converters to change the text format, then test the result in the actual player. Our conversion removes styling rather than promising identical appearance.
TXT is a transcript, not synchronized captions
TXT export removes the times. It is useful for reviewing the words or preparing notes, but a player cannot know when to show each line. TXT to SRT in our file tools estimates equal-length time slots from a duration you supply; it does not align text to spoken audio.
MP4 carries the visible design
A burned-in MP4 includes the words as video pixels. It works when viewers need the same fixed caption style wherever the file is posted, but those captions cannot be toggled off or corrected as a separate track. Check the actual rendered file, especially the longest line and the ending.
Download the current revision
In the project editor, subtitle-file download saves the current changes before requesting the file. If saving fails, correct the issue and retry rather than using an older download. Project SRT/VTT/TXT downloads require Pro or Max; editing a subtitle file you already have in the free file tools does not require a video project.
