When the upload box says “file too large”
Learning platforms cap uploads, and the cap is set by your institution rather than by the software — which is why the number differs between two courses on the same campus. In practice, per-file limits in the 20–250 MB range are typical, and some departments set them far lower to protect storage. Email is worse: Gmail stops at 25 MB for an attachment and Outlook's default is smaller still.
A 12-minute screen recording at 1080p is routinely over any of those. So is a scanned portfolio, a dataset with images, or a Unity build. The moment your work stops being a text document, the submission box stops being able to hold it.
A link sidesteps the whole category of problem because what you paste is text. Twelve characters of URL go into a box that would have rejected 900 MB of video. Your file lives at our end and the marker streams it from their browser.
- Free covers 100 MB of storage in total — a single file can use all of it — across up to 20 links. That is fine for documents and slides; video coursework will use it up fast.
- Pro raises the per-file ceiling to 200 MB, which covers most student video work at 1080p.
- A multi-file album holds up to 500 MB in total, so a report plus a dataset plus a demo fits in one link.
- Video that is still too big: export at 1080p rather than 4K and use H.264. A 10-minute screen recording drops from gigabytes to tens of megabytes with no loss a marker will ever notice.
