Turning audio and video into text: methods, accuracy, cost, and what to expect from AI compared with a person.
The transcript button goes missing for two very different reasons, and only one of them can be fixed by looking harder. Here is how to tell them apart and get the text.
A three-hour video does not have to cost you three hours — or ninety minutes at double speed — if you treat it as something to read instead of watch.
Speaker separation is a different task from recognising words, and it succeeds or fails almost entirely based on how the recording was made.
For students who catch two thirds of a lecture live, the fix isn't more vocabulary but a way to slow the lecture down after it happens.
Where Teams, Google Meet and Zoom actually put a meeting recording, what their own transcripts cover, and why downloading the file is the route that always works.
A straight answer on whether transcription can happen without your audio leaving the device, what encryption in transit actually covers, and the questions that separate real answers from marketing.
Before you transcribe a recorded call, settle whether the recording was lawful — then deal with narrowband audio, mixed channels, and the numbers you will have to check.
A day-long recording needs a different plan than a short one: split it by meaning, keep the timestamps, and expect the quality to drift.
macOS can extract the audio from a video without installing anything, but it stops short of transcribing it — here is the whole route, including where it breaks.
A practical walkthrough of pulling an exact quotation and its timestamp from a video, checking captions against audio, and formatting it for your citation style.
