My Camera wasnt set up correctly and time was on 2000 Jan 01. How can i offset each file and have the time stored correctly on the video files timestamps? So lets say i calculate the time diference and i find its 26 years + some months + some day etc. How do i go about adding this differential to each file with one click

I did a search for this & exiftool & ffmpeg were suggested.
I'm not sure if they can be used as batch for this.
It also depends on which type timestamp.
The ones that come up in Windows properties ?
Or burned in visible timestamps on the video itself.
I do not know a program that can do this with the second kind of timestamps. -
No I mean inside the file properties. Creation date modified date etc

If you want to change both use ffmpeg first.
If you want to change the metadata that MediaInfo detects with ffmpeg then:
I'm not good with script to do batch files but with this ffmpeg code you or someone should be able to.Code:ffmpeg -i input.mp4 -c copy -metadata creation_time=2012-12-17T21:30:00Z output.mp4
This tool should do what you want:
https://www.nirsoft.net/utils/bulk_file_changer.html
The above program is supposed to do batch or bulk but I only tested with one video file.Last edited by cholla; 21st Oct 2026 at 18:05.

exiftool can do the whole batch with a fixed offset in one command, so you don't need to set each file's date by hand. The shift syntax is "+=Y:M
h:m
". For example, to add 26 years, 3 months and 14 days to every MP4/MOV in a folder:
exiftool -api QuickTimeUTC "-QuickTime:CreateDate+=26:3:14 0:0:0" "-QuickTime:ModifyDate+=26:3:14 0:0:0" "-QuickTime:TrackCreateDate+=26:3:14 0:0:0" "-QuickTime:TrackModifyDate+=26:3:14 0:0:0" "-QuickTime:MediaCreateDate+=26:3:14 0:0:0" "-QuickTime:MediaModifyDate+=26:3:14 0:0:0" -ext mp4 -ext mov "D:\Videos\Camera"
Then copy the corrected date into the Windows file dates, which is what Explorer's "Date created" and "Date modified" columns show:
exiftool -api QuickTimeUTC "-FileCreateDate<QuickTime:CreateDate" "-FileModifyDate<QuickTime:CreateDate" -ext mp4 -ext mov "D:\Videos\Camera"
A few things to watch:
- Work out the exact offset from one clip whose real date and time you know, and put the hours and minutes in too if they're off.
- QuickTime dates are supposed to be stored in UTC. -api QuickTimeUTC makes exiftool convert to your local time. If the result is off by your time-zone offset, run it again without that option.
- exiftool keeps a backup of each file as *_original. Check a few clips first, then delete the backups or add -overwrite_original next time.
- If the camera wrote AVCHD .MTS files, exiftool can't write those. Remux them to MP4 first, or just fix the file dates with Bulk File Changer as cholla suggested. -
I tried fred_abila method & it works for the most part.
It did not change the Media Created date in Windows\Properties\Details.
It did not change the Tagged date in MediaInfo.
Unless all the video files have the same timestamps then the calculation will need to be done for each file individually.
I figured a way to batch change the dates in MediaInfo with ffmpeg.
You need to do this first.
1. Place video files in their own folder & copy ffmpeg.exe into this folder.
2. Create another new folder & name it.
Example to show how the code is done:Code:for %f in (*.mp4) do ffmpeg -i "%f" -c copy -metadata creation_time=year-month-dateT0hour:minutes:secondsZ "path to new folder\%f"
Then add the files in the "new folder" to BulkFileChanger.Code:for %f in (*.mp4) do ffmpeg -i "%f" -c copy -metadata creation_time=2026-10-22T04:08:00Z "C:\Users\USER\Desktop\TEST\1\%f"
It does batch to the files added.
EDIT pulldown/Select All
Actions pulldown/ Change Time/Attributes
Set the times you want.
Uncheck: Time is specified in GMT & Date/time sequence mode
Date/time sequence mode was already unchecked. I tried it checked & could not tell the difference. -
This is a test that I, sort of, have to sneak up on.
Set mediainfo to reflect the path yo your copy of MediaInfoCLI.exe
Change the video name to one of yours for testing.
get_dates- V01.cmd
Are any of the dates in test01.txt what you want? If so, which parameter(s) are they? Maybe post the content test01.txtCode:@echo off set mediainfo=C:\VidAud\MediaInfoCLI\MediaInfo.exe if exist test01.txt del /q test01.txt set all_dates=Recorded_Date Encoded_Date Tagged_Date Written_Date Mastered_Date File_Created_Date File_Created_Date_Local File_Modified_Date File_Modified_Date_Local Original Released_Date for %%a in (%all_dates%) do call :process1 "%%a" test01.txt Exit :process1 set param=%~1 echo %~1 >> "test01.txt" "%mediainfo%" "--Output=General;%%%~1%%" "My Best Video.mkv" >> "test01.txt"

@ pcspeak,
I tried the batch file you posted.
All I get is a quick run & then the command prompt disappears.
No test01.txt file is created.
I changed the path for mediainfo.exe to my location & named one of my files in place of "My Best Video.mkv".
I do not know where it went wrong but no text file was created. -
Interesting. I copied the code from my post, ran it, and got a test01.txt file.Originally Posted by cholla

If therock003 used any of the information posted would you post what you used & if it worked.
@ pcspeak,
I still can not get your code to work.
Using the method I posted in post #6 first on the .mov file.
It did lead me to try this: ( It is a command instead of a script batch file.)
This is the test01.txt file it created: (it is long & I used an early date. The camera in the text was not even made then.)Code:mediainfo --full "C:\Users\USER\Desktop\EDIT\MediaInfo_CLI\1\Test1.MOV" > "C:\Users\USER\Desktop\EDIT\MediaInfo_CLI\test.txt"

Uploading & then downloading changed these in the test01.txt file .
Regular MediaInfo still shows only 1970-10-22 04:08:00 UTCCode:File creation date : 2026-10-24 16:20:51.250 UTC File creation date (local) : 2026-10-24 11:20:51.250 File last modification date : 2026-10-24 16:20:51.684 UTC File last modification date (local) : 2026-10-24 11:20:51.684
Windows/Properties shows all with the Current date. So the file would need to have BulkFileChanger used again.
Even before the upload & download as soon as opened with Windows/Properties the "Accessed" changed to the current date.Last edited by cholla; 24th Oct 2026 at 12:34.
