Hello,
What do lines 43 and 44 do ?
Are they putting a timestamp into the encoded file itself ?

Thank You

Yes, the idea is just to reset creation and last update time to the one of the original file. This is useful for some tool that organize video by these fields...

@davideicardi
I understand.
Thank you for clearing that up.
