How to change the internal Encoded Date + Tagged Date of a MP4 video file?

Is there a way to change the internally stored Encoded date and the Tagged date in a MP4 video file without re-encoding?

where (/how) did you find such a date ?

I don't usually reply in the Newbies forum, but since nobody is replying and I have nothing to do during my lunch break at work, here I am...
Do you actually want to modify it or just get rid of it?
'cause a simple remux with let's say MP4Box will get rid of it.
Otherwise, if you wanna change it, you can use ffmpeg to change it to a specific time by remuxing it, like:

Code:

ffmpeg.exe -i "input.mp4" -c:a copy -c:v copy -metadata creation_time="2020-07-30 12:59:20" -f mp4 "output.mp4"

Cheers,

by default, remuxing with ffmpeg also removes this metadata (written by handbrake for instance).

ffmpeg -i input.mp4 -c copy output.mp4

-f fmt (input/output)
Force input or output file format. The format is normally auto detected for input files and guessed from the file extension for output files, so this option is not needed in most cases.
