I wonder how hard it would be to automatically add slides by scanning the talk video for points at which the on-screen slides change and mixing a frame from the video into the transcript at the relevant point.

1. Automatically detect when (timestamp) change in slide, e.g., large % of colour change in the image of the video (I assume video is slide-deck only else we can crop to the area that is);

2. Use the timestamps provided by whisper to group and align with (1).
