How many minutes is a semester of lectures? About 2,250 for one course.
A typical college course that meets 150 minutes a week for 15 weeks adds up to about 2,250 minutes, or 37.5 hours, so a four-course load comes to roughly 9,000 minutes of lectures. Every class uploads as its own file (up to 10 hours or 5 GB), is transcribed at about 2 minutes per audio hour, and after the first 20 minutes free, one course fits inside the $24 pack (5,000 minutes) with room for a second.
Counting a term
The arithmetic behind a semester of class time.
Three ways a week reaches 150
Three 50-minute meetings, two 75-minute meetings or one long evening block of 150 minutes all land on the same weekly figure. Multiply by the weeks that actually have teaching, usually 14 or 15, and you have the course total.
Holidays and exam weeks shrink it
A semester with a reading week and a final exam period often has only 13 teaching weeks. At 150 minutes a week that is 1,950 minutes, which slips just under the $12 pack's 2,000. Count your syllabus dates before you buy.
Quarters, seminars and labs
A ten-week quarter at 150 minutes a week is 1,500 minutes. A weekly three-hour graduate seminar over 15 weeks is 2,700. Lab sessions are rarely worth recording, so most students leave them out of the count.
Where the recordings come from
Phone voice memos, a lecture-capture download, a Zoom cloud file or a YouTube or Vimeo link your instructor posted. Files go in from this page or the upload page; links are pasted and fetched for you.
Before and after
A term of recordings nobody has time to replay.
✗ Thirty-seven hours of audio
A full course recorded but never reopened, because finding one explanation means scrubbing through weeks of class.
- Lectures stored by date only
- No way to search last month's class
- Exam week spent replaying old classes
- Handwritten notes missing the key example
- Files too large for some upload boxes
- No sense of how many minutes you have
✓ A searchable semester
Each class becomes text with chapters, so revision starts from the topic, not from the timestamp.
- Every lecture as one transcript
- Chapters marking each topic shift
- Formulas, dates and names listed
- A chat to ask about the course
- Word files for revision, SRT for captions
- One pack covering the whole course

FAQ
Semester totals, answered.
How much does it cost to transcribe a whole semester of one course?
At about 2,250 minutes, one course goes past the 2,000 minutes of the $12 pack, so the $24 pack (5,000 minutes) is the one to buy, and it leaves around 2,750 minutes for a second course. If your term has only 13 teaching weeks, the $12 pack covers it.
And a full course load?
Four courses at 2,250 minutes each are about 9,000 minutes, which two $24 packs cover with roughly 1,000 minutes to spare. Many students record only the two or three courses they find hardest, which keeps it to one pack.
Do I upload the semester all at once or class by class?
Either works. Each lecture is its own file and its own transcript, so most people upload after each class and let the minutes run down through the term. A folder of recordings can also go up together at the end.
What happens to unused minutes at the end of term?
They stay on the account. Packs are one-time purchases, credits never expire and there is no subscription, so leftover minutes carry straight into next semester.
My lecture video is over 2 GB. Will it upload?
Before your first pack, uploads can be up to 2 GB; a larger file starts once a pack is on the account. Any single file can go up to 10 hours or 5 GB. Lecture-capture video in high resolution is the usual case; the audio track alone is far smaller.
Which languages and formats come back, and who sees my recordings?
Lectures in 99 languages are detected automatically, including classes that switch between two, and transcripts export as TXT, DOCX, SRT, VTT or JSON. Class recordings are transcribed on our own servers and are never used for training.
