Stamp Info creates a frame around the rendered images and writes scene information on it. It is a flexible alternative to the Metadata post processing integrated system of Blender.
This tool is currently supported for LTS version of Blender 2.93 and up to Blender 3.0
It was initially developed for an animated TV series production in 2020 on Blender 2.83. It has the features that were needed at the time but it may not be considered as feature complete for a more generic purpose. In spite of all our efforts to make it reliable some troubles may occur in use cases we have not faced.
Stamp Info can be installed as any standard Blender add-on. Nevertheless:
The addon must be installed in Administrator mode so that the Pillow Python library can be downloaded and deployed correctly. Also be sure that your firewall doesn't block the download (or use OpenVPN or equivalent).
Refer to the documentation for the detailed installation steps: https://ubisoft-stampinfo.readthedocs.io/en/latest/getting-started/install.html
- When pressing one of the 2 render buttons of the Stamp Info panel 2 temporary sets of images are generated:
- The rendered images, as for a classical rendering. They are put in a temporary folder though, at the root of the rendering path;
- The "stamped info" images are generated with PIL, the Python Image Library. They received a frame and the text for all the specified metadata to display;
-
Then the 2 sets of images are composited into the VSE thanks to a routine. This produces the final rendering sequence and it is stored in the rendering path specified in the scene.
-
Unless changed in the Preferences both temporary folders are then deleted.
Note: In order to mimic as much as possible the actual way of working of Blender and so as to avoid frames in a rendered sequences to be overwritten by mistake the still images are saved on disk with a file name starting with the prefix "_Still".
This add-on requires the Python library Pillow. This library is automatically downloaded and deployed on the Blender instance when Stamp Info is installed.
Files located in the utils\ directory are independent modules that can be re-used in other Blender add-ons.
The following ones are particularly interesting:
