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.

enter image description here

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.

  • $\begingroup$ @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. $\endgroup$

Looking at the Blender source code, the copyright seems to be hard-coded with the line:

[qtexport->movie setAttribute:@"Made with Blender"

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.

  • $\begingroup$ Not as far as I am aware. Anything like that would be done with the Python API, but I can't find anything that would allow that. $\endgroup$ Aug 11, 2016 at 13:04
  • $\begingroup$ Well this is intended to add an author attribute to the blend file along with anything exported from it. How about the metadata function under the render tab where it says notes. Would that be transferred onto the movie file? I know it works for individual jpeg and png image files. $\endgroup$

  • $\begingroup$ Yes, it would be transferred onto the file, but you may need other tools to be able to read back that metadata as opposed to seeing it in the window in your screenshot. See: blender.stackexchange.com/questions/48700/… $\endgroup$ Aug 11, 2016 at 13:17
  • $\begingroup$ For the image outputs, I can see the metadata straightaway by opening it in a text application and looking at the compiled mess. No problem. My real issue is if the metadata option applies to video outputs because I tried looking it up in the compiled mess of the mov file and found nothing. $\endgroup$
