Convert and Compress Online Lesson Recordings (Zoom, Meet)
Online lesson recordings pile up fast — a one-hour Zoom can easily be 1–2GB. Whether you're a tutor sharing replays with students or a learner archiving classes, AVMint lets you shrink, convert and trim those files entirely in your browser.
Who is this for?
- Teachers and tutors who record Zoom or Google Meet lessons and share them with absent students.
- Students who download class recordings and want them to take less storage on their laptop or phone.
- Schools and cram schools that need to archive lessons without sending sensitive student footage to a third-party server.
How to process a lesson recording
Convert if needed
Zoom often saves recordings as MP4, but Meet may give you a format you can't easily play. Use AVMint Convert to get a clean MP4 with H.264.
Trim dead air
Open AVMint Trim and cut the waiting-room minutes and the goodbyes at the end. Even five minutes off the front shrinks the file noticeably.
Compress for sharing
Send the trimmed file into Compress and target a size that fits your LMS or cloud drive — 200–500MB usually works.
Share the smaller file
Download the compressed lesson and post it to Classroom, Notion, or your LMS. Students download faster, on less data.
FAQ
Is it safe to use AVMint with footage that contains students?
Yes. AVMint runs entirely in your browser using WebAssembly. The video file is never transmitted to AVMint or any third party. This is important for student privacy and FERPA-style policies.
How much can I shrink a one-hour Zoom recording?
A typical one-hour 1080p Zoom recording is around 1GB. Compressing to 720p with a moderate bitrate can bring it under 300MB without making the slides hard to read.
Can AVMint extract just the audio for a podcast version?
Yes. AVMint Extract Audio pulls the soundtrack out as MP3 or AAC, perfect for sharing audio-only lesson recaps.
