Sorry, I miswrote what I was thinking. You are right that the transcripts for both purposes must contain all the important visual information. However, I believe there can legitimately be other differences.

Assuming we are talking about synchronised media, a transcript only gets you to level A conformance (SC 1.2.3). If you want to achieve AA, you must have an audio description (except in the case of a single talking head). Therefore, the transcript does not need to meet the requirements of SC 1.2.3 because the audio description already does that.

The transcript only needs to meet SC 1.1.1 because it is only acting as a text alternative for an image of text. As such, it doesn't need to contain any of the audio content.

Unless I'm wrong again.
