Biology 101 · Lecture transcript

Think of ATP as a transferable energy currency, not long-term energy storage.
This distinction matters when we compare cellular respiration with photosynthesis.

Questions About Lecture Transcription
Keep the complete transcript and original recording together, then move into other study tools when you are ready.
How does lecture transcription work?
Record a lecture in your browser or upload an audio or video file. ClassLecture processes the recording into a searchable transcript with timestamps you can use to return to the original audio.
Which audio and video formats can I upload?
You can upload common lecture formats including MP3, M4A, WAV, MP4, and MOV. The upload screen checks the file before processing begins.
Can I record a lecture in my browser?
Yes. You can record a lecture from a laptop or phone browser and follow its saving and transcription progress in the same class workspace.
Can I upload a lecture I already recorded?
Yes. Upload an existing audio or video recording, or select a lecture you previously added to the class.
Do timestamps link back to the recording?
Yes. Select a transcript timestamp to play the original recording from that moment, so you can hear the surrounding context and verify important wording.
How long does transcription take?
Processing time depends on recording length and current demand. The class workspace shows each stage and an estimated processing time while your lecture is being prepared.
How accurate is the transcript?
Accuracy depends on audio quality, background noise, accents, and overlapping speakers. Speech recognition is not perfect, so use the timestamped recording to verify wording that matters.
Can I start free?
Yes. Start by recording or uploading a lecture, then open the searchable transcript in your class workspace.
What if the audio is unclear or processing fails?
Your recording stays in the class workspace. You can review the status, retry when available, or replace an empty, unsupported, or unusable recording.
Can I use the transcript for other study tools?
Yes. Once the transcript is ready, the same lecture can support cited questions, focused summaries, practice quizzes, and flashcards.
