Timestamp Burner

Stamp date, time and running timecode permanently onto your video — dashcam and CCTV style. Live preview, export as WebM. Free, private, no watermark.

100% private — your video never leaves your device

Burn a timestamp onto video

All processing is on-device. Export is a real-time re-encode — a 3-minute video takes about 3 minutes. Output is WebM with audio.

Video file MP4, WebM — plays in your browser

How it works

1

Load your video

Drop in any MP4 or WebM. The preview plays your footage with the timestamp overlaid exactly as it will be burned — what you see is what the export gets.

2

Design the stamp

Toggle date, time and running timecode independently. Pick a corner, font size, color and background — the classic CCTV look is yellow on a dark box, bottom-left.

3

Export in real time

Click export and the video plays through while every frame is captured with the stamp drawn on. Download the WebM — the timestamp is part of the picture.

When a burned-in timestamp beats metadata

Every video file already carries a creation date in its metadata — but metadata is the first thing that dies in the wild. Messaging apps strip it, social platforms re-encode it away, and screen recordings never had it. A burned-in timestamp is pixels, not metadata: it survives every re-upload, every transcode and every platform that touches the file. That is why dashcams, CCTV systems and body cameras burn the date and time into the frame itself — the stamp is the evidence, not an annotation of it.

The three stamp elements serve different jobs. The date answers "when was this?" for documentation, insurance clips and archival footage — choose "File date" to stamp the video's own modification date rather than today. The clock time adds precision for incident review. The running timecode is the editor's tool: HH:MM:SS:FF counts frames from your chosen start offset, so you can reference "01:12:04:17" in notes and find the exact frame instantly. Match the frame-rate setting to your footage (30 for most phone recordings) so the FF counter rolls over the way your editor expects.

Two honest notes. First, this stamp is permanent — check the position against your footage before exporting, because bright areas can swallow a white stamp (that's what the dark box background is for). Second, the export is a real-time re-encode in WebM, the only container browsers can write: a 5-minute video takes 5 minutes to export, and you should keep the tab focused. For anything that needs an MP4 container afterwards, HandBrake or CloudConvert will remux the WebM losslessly in seconds.

Choosing a Frame Rate

Match your source: 30 fps for most phone footage, 24 for cinematic, 60 for sports or gaming. A mismatched rate makes the timecode drift from the actual frames — at 30 fps each frame is 33.3 ms, so the wrong rate visibly skews the last digits within seconds.

Limitations

The stamp is burned in permanently and the export is WebM, not MP4. Date and time come from your device clock or the values you type — the tool cannot read the recording date from the file itself.

Frequently asked questions

The date/time stamp shows a fixed calendar moment — either today or the file's own modification date — on every frame, like a dashcam. The running timecode (HH:MM:SS:FF) counts up with the video from your chosen start offset, which is what editors use to reference exact frames.
Match your footage: 24 for cinema, 25 for PAL regions, 30 for most phone and screen recordings, 60 for high-frame-rate clips. The rate only changes how the FF (frames) counter rolls over — the stamp stays accurate to the video's actual playback position.
WebM (VP9/VP8 video with Opus audio), re-encoded in real time while the timestamps are drawn onto each frame. It plays in all modern browsers and uploads to YouTube and most platforms.
The export is a genuine real-time re-encode: your video plays through once while each frame is captured with the stamp drawn on. A 3-minute video takes about 3 minutes. Keep the tab focused while it runs.
No. Loading, the live preview, timestamp rendering and the re-encode all happen locally in your browser. Your footage never leaves your device.
The running timecode includes frames (HH:MM:SS:FF), which is the video-standard way to show sub-second time. True milliseconds aren’t part of the timecode format.
Yes — it’s baked into the pixels. Compression may soften the text slightly at low bitrates, so use a large, high-contrast style for maximum legibility after upload.
