Frequently asked questions
What is an add subtitles to video tool?
It renders subtitle text into video frames so the downloaded clip includes visible captions. SocQ accepts SRT or VTT and exports an MP4.
Which subtitle formats can I add?
Open an SRT or VTT file or paste its content. Each cue should have valid start and end times plus the words to show.
Can I change the subtitle appearance?
Yes. Choose the text size and color. The export uses an outline to help captions stay readable over the video.
How does trimming affect subtitle timing?
Use timestamps from the original video. The tool selects subtitles inside your chosen range and shifts them to match the exported clip.
Can I use Chinese subtitles?
Yes. The subtitle renderer loads a font with Chinese and Latin characters when you export. Use UTF-8 subtitle text to preserve the wording.
How do I create subtitles from speech first?
Use Video to Text to generate a timed transcript, review the SRT in the Subtitle Editor, then add it here to create the captioned clip.
