Hello I have an MP4 video, I want to change the creation_time using ffmepg, without changing the rest of metadata. but I am facing some problems..
The major_brand and more stuff are changed. I want those to be the same. if I put it in ffprobe.exe this is what I see:
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '6.mp4':

I want to change the creation_time of the video, when I run :
ffmpeg.exe -i 6.mp4 -metadata creation_time="2013-06-22 15:00:00" -acodec copy -vcodec copy output.mp4
I get:
Output #0, mp4, to 'output.mp4':

According to the output and because I chose "-acodec copy -vcodec copy" everything should stay the same. But when I run ffprobe for the newly created .mp4 file. Here is the output:
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'output.mp4':

As you see everything has changed, even though i chose to keep everything the same.
Please help me on this. Thanks!
