Why course creators move their videos

A course is only as good as the lesson a student can actually finish. Three problems push teachers and learning platforms to look for a new home for their video.

Students drop out when the video freezes

Many learners study on a commute, on shared Wi-Fi, or on mobile data. A lesson that stalls every few minutes is a lesson they stop watching. Video that switches to a lighter version on a weak connection keeps them in the lesson.

Free video sites send students somewhere else

A lesson on a free video site comes with ads, someone else's logo, and a sidebar of other channels' videos. The student you paid to acquire is one click away from a competitor's course.

The bill depends on where your students live

When your course takes off abroad, a video bill that changes by region can turn your most successful market into your least profitable one. A single rate keeps the price of a student the same everywhere.

What a month of lessons costs

A course business with 2,000 active students, each watching 10 hours of lessons a month in HD, with a 400 GB library of recorded lessons.

Hours watched
20,000
Video delivered (HD at 3 Mbps)
27,000 GB
Streaming at $0.0049/GB
$132.30
Storing 400 GB of lessons
$4.00
Preparing videos for every screen
$0.00
Monthly total
$136.30

That is about $0.07 per active student a month, and the figure is the same whether those students are in London, Lagos, or Jakarta. Students on slow connections receive a lighter version, so they cost less to serve, not more. Try your own numbers on the pricing page.

What stays yours, and what we take on

ZeroBuffer hosts and streams the lessons. Everything that makes it your course stays where it is.

  • Your course site or appstays yours

    Keep the site, checkout, and student accounts you already run. The player goes on your lesson pages; students never leave your site to watch.

  • Your brandstays yours

    No ads, no other logos on the player, and no recommendations for anyone else's videos at the end of a lesson.

  • Your original recordingsstays yours

    Upload from your computer or import straight from a link. Your masters stay in storage you can reach at any time, and you can take them with you.

  • Getting every lesson ready for every screenwe handle it

    Each upload is prepared in several qualities, up to 4K, with a thumbnail, at no charge. You don't touch export settings.

  • Smooth playback on weak connectionswe handle it

    Each student receives the best quality their connection can handle, and the player steps down to a lighter version instead of freezing.

  • Organising a growing librarywe handle it

    Group lessons into collections by course or module, and give teaching assistants and editors their own access with permissions.

Moving your course videos in four steps

Most course creators can move a first module in an afternoon and the rest when they're ready.

  1. 1

    Upload or import one module

    Drag in a few lessons from your computer, or import them from a link to wherever they're stored today. Group them into a collection for the course.

  2. 2

    Watch them from where your students are

    Play the lessons on a phone on mobile data, a laptop, and a TV. That is the test that matters, and it costs nothing to run.

  3. 3

    Put the player on one lesson page

    Add the player to a single lesson in your course and let a few students use it before you change anything else.

  4. 4

    Move the rest of the catalogue

    Import the remaining lessons and swap the players course by course. Keep the old host until the last course has moved.

What every lesson gets

Everything below ships today and is included with every upload.

  • Preparation in several qualities up to 4K, with a thumbnail, at no charge.
  • A player for your website or app that works on phones, laptops, tablets, and smart TVs.
  • Smooth playback on slow connections: the player steps down instead of freezing.
  • Collections to organise lessons by course or module.
  • Team members with permissions for teaching assistants and editors.
  • Instant removal when a lesson needs to be taken down or replaced.
  • A 99.99% uptime SLA with service credits.

When we are not the right home for your course

We'd rather say so now than after you've moved. Four cases where something else will serve you better:

  • You want an all-in-one course builder with quizzes, certificates, and checkout. We host and stream the video; pair us with the course platform or site you already use.
  • You teach live classes. ZeroBuffer is built for recorded lessons today.
  • Your contracts require studio-grade copy protection (DRM) on every lesson. We don't offer it yet.
  • You need watch-time reports per student today. Viewer analytics are coming soon, and we won't claim them until they ship.

Frequently asked questions

Can I put lessons on my own course site?
Yes. Every video comes with a player you can add to your website or app, and it plays on phones, laptops, tablets, and smart TVs, with no ads and no one else's logo.
Will lessons play for students on slow internet?
Yes. Every upload is prepared in several qualities, up to 4K. Each student receives the best quality their connection can handle, and the player switches to a lighter version instead of freezing.
Can I move my existing course videos?
Yes. Upload files from your computer, or import them straight from a link to wherever they're stored today. Group them into collections by course or module.
Can I limit lessons to paying students?
Paid access links are coming soon. Until they ship, keep lessons behind your course site's own login, which is where students already sign in.
What does it cost to host a course?
You pay for the video your students watch: about $0.0066 per hour of HD (720p at 3 Mbps) or $0.011 per hour of Full HD (1080p at 5 Mbps), the same in every country. Preparing videos is free, storing them is $0.01 per GB a month, and there are no plans, contracts, or per-student fees.
Do you support live classes?
ZeroBuffer is built for recorded lessons today. If you're planning live sessions, contact sales and tell us about your classes.
