You can use the generated video in any editor that supports chroma keying (green/blue screen), such as Adobe Premiere, Final Cut, CapCut, or DaVinci Resolve.
Subtitle Generator supports two input methods:
Script/Text: Type or paste your script, and the tool will automatically split it into subtitle segments and generate timings for you.
SRT File: Upload a standard SRT (SubRip Subtitle) file with your own timings and text. The tool will use your exact timings for the video.
You can also download your subtitles as an SRT file for use in other platforms or editors.
Absolutely! The subtitle videos you create are perfect for YouTube Shorts, TikTok, Instagram Reels, and any other platform that supports video uploads. The green/blue/black screen backgrounds make it easy to use chroma key (color key) effects in your favorite video editor, so you can overlay the subtitles on any video. There are no watermarks, and you have full control over the style and timing.
Browsers can only export video as WebM format. To convert your subtitle video to MP4, you can use free tools like HandBrake, VLC, or online converters. For advanced users, ffmpeg can also be used: ffmpeg -i input.webm -c:v libx264 -crf 23 -preset veryfast output.mp4

Yes, your privacy is a top priority. All subtitle processing is done locally in your browser—your script, SRT files, and generated videos never leave your device. No subtitle data is uploaded or stored on any server. The only data collected is anonymous usage statistics via Google Analytics, which helps us improve the site. See our Privacy Policy for full details.
For privacy and browser compatibility, Subtitle Generator only exports the subtitle animation as a video (WebM) without audio. This ensures your audio files are never uploaded or processed. You can easily add your own audio track in any video editor after downloading the subtitle video.
