Add SRT/VTT subtitles to a video as soft (selectable) or hard (burned-in) captions.
Both the video and subtitle files are uploaded to ConvertCraft servers where they are processed in an isolated FFmpeg pipeline. All source files and the output file are permanently deleted from the server immediately after processing — no subtitle text or video content is stored or logged.
Embeds or burns subtitle tracks into video using two distinct methods. Soft subtitles use -c:s mov_text (for MP4) or -c:s srt (for MKV) to add the subtitle as a selectable track without re-encoding. Hard subtitles use the subtitles filter — subtitles=filename.srt — with force_style parameters like FontSize, PrimaryColour, and MarginV to render text directly onto the video frames using ASS override tags.
Essential for adding accessibility captions to social media videos, subtitling foreign-language films or interviews, or burning translations directly into content for platforms like Instagram, WhatsApp, or TikTok that strip embedded subtitle tracks. Also useful for creating accessible training videos, embedding closed captions for compliance, or adding chapter-style annotations to presentation recordings.
