# How do I change the Copyright information on a rendered file before rendering?

I was looking at one of my render outputs (from blender render) and when I looked in more info (on OSX), I saw something that caught my eye.

How do I make it so that I can change that text in Blender before rendering? I'm using Quicktime with H.264 output but was wondering if I could do this with other video output types. I'm assuming python is required.

• You can always render it out as a PNG sequence then bring it into another program to render it out as a QT file. – icYou520 Aug 11 '16 at 14:49
• @icYou But my question is to do it inside blender. I know that I can do that outside but it kinda dilutes the challenge, and won't work for my situation, which is to distribute a blend file publicly that will have my copyright info in it which would be transferred into any exported media. – Bradman175 Aug 11 '16 at 22:18

For this reason I don't think the copyright message is configurable via the interface nor via Blender's Python API, meaning the only option is to edit the copyright manually after rendering or see if you can write a Python script to do this (which would be a question for StackOverflow) and get it to execute automatically after rendering with an app.handler.
