Upload a video and AI transcribes, times and burns in your captions automatically.
Most social video is watched on mute, so captions are the difference between someone stopping and scrolling past. VdoZen transcribes the speech, times each line, and burns the subtitles into the video itself — no subtitle file to write, no editing software, and nothing for a platform to hide behind a settings toggle.
Pick from 29 caption styles and drag the band to place them anywhere on the frame. MP4, MOV or WebM up to 500MB, vertical or horizontal, with no watermark on any plan.
No transcript to write and no editor to open — upload, pick a look, and the captioned file is what you download.
MP4, MOV or WebM, up to 500MB and 20 minutes. Works for both vertical (9:16) shorts/reels and horizontal (16:9) video.
Choose from 29 styles — clean single-line, karaoke fills, word-by-word highlights, emoji pops and more — then drag the band to set where they sit on the frame.
The audio is transcribed, each line is timed to the speech, and the captions are burned into the video itself — no separate subtitle file, nothing to toggle on the viewer's end.
Writing captions by hand means listening to your own video line by line and typing out a timed transcript — for anything longer than a minute that's the slow part, not the editing. VdoZen replaces that step: upload the file and the speech is transcribed and timed automatically, so there's no .srt file to write or sync by ear.,The captions aren't a track laid over the video either — they're burned directly into the frame. That matters for anywhere the viewer doesn't control caption settings, which in practice is most short-form feeds: TikTok, Reels and Shorts don't reliably surface an uploaded subtitle file, so a caption a platform could hide is a caption most viewers on mute will never see.,Placement is adjustable, not fixed. After the video uploads, a caption band overlays the real frame and you drag it to wherever reads best against your footage — over a lower third, closer to center, wherever the shot needs it — and the position holds at whatever resolution the source video is.
New accounts get free tokens with no credit card, which covers captioning a video end to end — upload, pick a style, generate, download. Nothing exported from VdoZen carries a watermark, on the free plan or any paid tier.,That's a real difference from most free caption tools, which either cap you at a short clip length, stamp a logo into the corner of the export, or both. A 500MB, 20-minute cap and a genuinely watermark-free file is what the free tier here actually gives you, not a trial of a paid feature.
Yes — you get free tokens when you sign up, with no credit card required. A short video costs only a few tokens to caption, so you can try the full flow before deciding whether to buy more.
No. Videos you export from VdoZen have no watermark on any plan, including the free tier. What you download is what you can publish.
MP4, MOV and WebM files up to 500MB and 20 minutes long. Both vertical (9:16) and horizontal (16:9) videos are supported, and captions are scaled to match your source resolution automatically.
Yes. After uploading, drag the caption band up or down over your video to set the vertical position. The placement is applied at the correct scale whatever resolution your source video is.
29 styles, from clean single-line captions to karaoke fills, word-by-word highlights, emoji pops and typewriter effects. Five are available on the free plan and the rest unlock on paid tiers.
Yes. Upload your video and the speech is transcribed and timed automatically — you don't need to write or upload a subtitle file.
Not directly — ChatGPT is a text chat interface and doesn't accept or process video files on its own. Some setups pair it with a separate transcription step (like Whisper) and video-editing code to burn in the result, but that's a multi-tool pipeline you'd assemble yourself, not something ChatGPT does in one step the way a dedicated captioning tool does.
No. VLC is a media player — it can display an existing subtitle file (.srt, .vtt) alongside a video, and some builds can search for and download a matching subtitle file online, but it doesn't transcribe your video's own audio or generate new captions from scratch.
If the video already has an official transcript or subtitle file somewhere (YouTube's auto-captions, a streaming platform's CC track), you can often export that. For your own footage with no existing transcript, you need a tool that transcribes the audio — VdoZen does this automatically and free tokens on signup cover trying it without a credit card.
