Subvideo.ai
What it is
Subvideo.ai is a web tool for creating subtitles from audio or video, editing subtitle text and timing in a browser, translating subtitles, and exporting subtitle files or video with captions burned in. Its subtitle studio uses a timeline for visual editing, styling, and syncing subtitles with audio. Speaker identification and caption styling are supported. Free subtitle downloads include SRT, ASS, VTT, SBV, and TXT formats. A voiceover workflow lets users choose a voice and language, adjust speed and pitch, then export an audio track or rendered video. The site presents workflows for YouTube, TikTok, Netflix, Premiere Pro, Final Cut Pro, and DaVinci Resolve. Uploads include common audio and video formats such as MP3, WAV, MP4, MOV, and WEBM. Burn-in requires a suitable media project containing a video file; a subtitle document alone is insufficient. Guest files are deleted 48 hours after processing, while free-plan video files are deleted after 30 days. The free account permits three uploads per day, and Ultimate costs $9.99 a month with no fixed daily upload count, subject to Fair Use. File and technical processing limits apply to every plan.
