One word edit suggestion

Original:
A transcript file, on the other hand, just contains the text of what was said in the video.

Change to:
A transcript file, on the other hand, just contains the "transcribed" text of what was said in the video.

Then create a hyperlink using "transcribed", linking to the definition and maybe the process you use.
