Is it possible to edit or correct the date and time displayed on video that has already been recorded on a Hikvision NVR?

Hi all,

I have a Hikvision NVR where the system time was set incorrectly, and some footage has already been recorded with the wrong date and time displayed on the video.

For example, the recorder was showing 05/02/2026 14:30 when the actual date and time should have been 09/02/2026 14:30. The footage has already been saved to the HDD.

Is it possible to edit or correct the date and time (OSD timestamp) on video that has already been recorded on a Hikvision NVR?

Thanks in advance.
