Select the timestamp region

Draw a tight box around the area where the timestamp, date code, or time watermark appears. The AI maps this region across every frame to ensure consistent removal throughout the entire clip.

AI removes the timestamp and restores the background

AI inpainting erases the time/date overlay and reconstructs the original footage behind it using surrounding pixels. Preview the result side-by-side, then download the clean export at original resolution.

Camera date stamp removal results

AI inpainting detects the timestamp region and reconstructs the hidden background pixel by pixel. The result looks like the date stamp was never there — no blur patch, no crop.

  • No blur or smudgeAI reconstructs the background behind the timestamp using surrounding texture and detail.
  • Full frame preservedNo cropping needed — the entire video frame stays intact at original resolution.
  • Works across camera typesHandles GoPro, camcorder, dashcam, and action camera date stamps in various font styles.

适合你自己拥有或已获授权的视频，例如原创短视频、品牌素材、课程片段和内部资料。

How do I remove the date and time from a video?

Upload your video to UnmarkAI, draw a box around the date and time stamp area, and the AI will erase the overlay and reconstruct the background behind it. The process works on camera date stamps, camcorder time imprints, CCTV overlays, and dashcam time codes — no cropping or blurring required.

Can I remove a timestamp from a video without cropping?

Yes. UnmarkAI uses AI inpainting to erase the timestamp and reconstruct the background behind it, so the full frame is preserved without any cropping.

What types of timestamps can AI remove from video?

AI can remove camera date stamps (GoPro, Sony, Canon), CCTV time overlays (Hikvision, Dahua), dashcam timestamps with speed data, old camcorder date imprints, and professional timecode burn-ins — as long as the overlay is burned into the visible frame.
