Per-Frame Metadata

February 11th, 2008 by Multimedia Mike

Someone asked me a question in email today that I thought I would pass on to the broader group. Are there any general methods for attaching general metadata — e.g., EXIF data — to individual video frames?

At first thought, this strikes me as a container-level matter. However, there could be a video codec that embedded metadata in each frame and could be stored in any generalized container format.

Personally, I have always been more aware of issues surrounding content playback vs. content creation which I admit is somewhat of a weakness in my overall multimedia knowledge. The submitter had in mind data along the lines of absolute timestamps and GPS coordinate information to be included with every frame. This may seem a tad excessive but you can never underestimate other peoples’ requirements.
