Upload your own lecture videos

You can add your own recorded lectures directly to a Blended course. Blended will transcode the video, transcribe it, detect topic boundaries, and draft notes from the transcript — all in the background — so a new lecture video becomes a fully-featured chapter page without any manual editing.

This article walks through the whole flow, from clicking Upload video to reviewing the finished page.

Before you start

  • File types: MP4, MOV, and WebM.

  • Where uploads land: each upload becomes a page inside a chapter. You choose whether to add it to an existing chapter or let Blended create a brand-new module and chapter for you.

  • Feature availability: the Upload video button only appears when the upload feature is enabled for your course. If you don't see it and you'd like to, contact your Blended Teaching account manager.

  • You do not need to stay on the page. Once the file finishes uploading, Blended processes it in the background. You can close the modal, navigate away, or come back the next day — the page will be ready when you return.

Step 1 — Start the upload

There are two places to start an upload. Pick whichever fits what you're doing.

Option A — Create a new chapter from a video (course structure page)

Use this when you're adding a fresh lecture and don't already have a chapter to drop it into. Blended will create a new module and chapter for you, automatically.

  1. Open the course's Organize Content tab (the default view of the Course Structure page).

  2. In the top toolbar next to Add Content, click Upload video.

  3. Choose your video file and click Start upload.

  4. Close the modal when the upload completes.

A new chapter appears in the module list automatically once processing finishes.

Option B — Add to an existing chapter (chapter editor)

Use this when you want the new video to sit inside a chapter you already have.

  1. Open the course, then open the chapter you want to add the video to.

  2. In the chapter editor's structure pane, find the section you want the video in.

  3. Open that section's Add content menu and choose Upload video.

  4. Choose your video file and click Start upload.

  5. Watch the progress bar. When it hits 100%, you can close the modal.

Step 2 — Let Blended process the file

The new page appears in the structure pane with a Processing badge. Behind the scenes, Blended is doing three things in sequence:

  1. Transcoding the file to a streamable format.

  2. Transcribing the audio into a word-level transcript.

  3. Detecting topic boundaries — the natural chapters inside the lecture.

For any video 20 minutes or shorter, processing continues straight through. Notes are drafted from the transcript, the Processing badge clears, and the page is ready.

For videos longer than 20 minutes, processing pauses after topic detection and asks you a question (see Step 3).

Where to watch progress

  • From the Course Structure page — a Processing videos panel appears above the module list while any upload is in flight. Each row shows the file name, its current phase, and a summary. Uploads still in progress have a Cancel button; anything that failed has a Retry button.

  • From the chapter editor — the page itself shows the Processing badge in the structure pane. When Blended is waiting for you to make a decision, the badge changes to Action needed.

Step 3 — For long videos: choose whether to split

When a video is longer than 10 minutes, Blended has usually detected more than one distinct topic inside it. Instead of dropping a 40-minute page on your students, it offers to break the lecture into shorter, topic-focused pages.

Open the page with the Action needed badge. The preview pane shows a Suggest a structure for this video? panel with two choices:

  • Suggest splits (recommended) — Blended runs a short AI analysis (about a minute) and proposes a set of pages, each with its own draft title. You get to review every proposed page before anything is published.

  • Keep as one page — skips the analysis and keeps the video as a single page.

Reviewing a proposed split

When the AI has finished analysing, a compact Suggested structure card appears next to the chapter structure. It shows the number of proposed pages, the AI's confidence, and its headline reasoning.

From here you can:

  • Publish split — accept the proposal as-is.

  • Keep as one page — throw away the proposal and go back to one page.

  • Open full review — open the full review page, where you can rename each proposed page, preview any segment, and nudge the boundaries.

The full review page shows one card per proposed page. For each card you can:

  • Rename the AI's draft title (click the pencil, then the green check to save or the red X to revert).

  • Preview a short clip of that segment.

  • Adjust the boundaries by clicking the time-range chip. Small −15s and +15s buttons appear, or you can type a precise m:ss value. When you move one boundary, Blended automatically moves the matching boundary on the neighbouring card so there are no gaps. Every page must be at least 1:00 long.

  • Reset to AI — undo any manual boundary changes and go back to what the AI suggested.

If the whole shape of the split is wrong (too many or too few pages), use the Fewer pages / About the same / More pages buttons at the top of the review page, or type a plain-language hint into Add a hint… — Blended will redraft the whole proposal.

When you're happy, click Publish N pages in the sticky bar at the bottom.

The video is not visible to students until you make a decision here. Both Publish split and Keep as one page count as a decision — after either one, Blended finishes processing and the video becomes available to publish.

Step 4 — Review and edit the notes

Once a page finishes processing, Blended has drafted notes from the transcript. These appear alongside the video for students.

To edit them:

  1. Open the chapter and select the video page.

  2. In the preview pane's toolbar, click Edit notes.

  3. The notes editor opens with the AI draft loaded in a rich-text editor.

  4. Edit as much or as little as you want, then click Save.

While you're in the notes editor, you can also:

  • Regenerate — replace the current notes with a fresh AI draft from the transcript. If you have unsaved edits, Blended asks you to confirm before overwriting them.

  • Download the transcript or notes — links appear in the page header once the video has finished processing.

  • See the video topic tags — the chapters detected inside the lecture — as a reference while you write.

If another instructor is editing notes for the same page at the same time and saves before you, you'll see a conflict banner. Choose Keep mine to save your version over theirs, or Load theirs to discard your local changes.

Step 5 — Publish the page for students

Uploaded video pages start unpublished, so students can't see them yet.

To publish:

  1. Select the page in the chapter editor.

  2. Click Publish in the preview toolbar.

If the parent chapter or module is unpublished, publish those first — the button is disabled with a tooltip while a parent is still unpublished.

Downloading the transcript and notes later

You don't have to open the notes editor to get the files. Select an uploaded video page in the chapter editor, and scroll to the bottom of the preview pane — a download row appears with links for the transcript and the notes.

Managing uploaded videos

Move an uploaded video to a different module

  1. On the Course Structure page, open the chapter's action menu (⋯).

  2. Choose Move to another module.

  3. Pick a destination module and click Move Chapter.

The video, transcript, and notes all move with the chapter.

Delete an uploaded video from a module

Uploaded video chapters aren't destroyed when you delete them from a module. Deleting only unlinks the chapter — the video, transcript, and notes are preserved.

To re-add an uploaded video you previously removed:

  1. Open the module you want it in.

  2. Click Add Chapter.

  3. In the picker, look under Your uploaded content — every uploaded video you've ever removed from a module lives there. Select it to add it back.

If you need to permanently delete an uploaded video, contact Blended Teaching support.

Retry a failed upload

If an upload fails during processing, the row in the Processing videos panel shows a Retry button. Click it to re-run processing on the same file — you don't need to re-upload.

FAQ

How long does processing take?
Shorter videos are usually ready within a few minutes. Longer videos take proportionally longer, mostly because of transcription. If Blended is proposing a split, expect roughly an extra minute for the AI structure analysis.

Can students see the video while it's processing?
No. The page stays unpublished throughout processing and split-review. Students see nothing until you publish the page yourself.

Can I re-run the AI notes on an already-published video?
Yes. Open the page, click Edit notes, and click Regenerate. Save when you're happy with the result.

Can I use the same video in more than one course?
Each upload lives in the course you uploaded it to. To use it elsewhere, upload the file again from within the other course.

What happens if I close the tab while a video is uploading?
The upload itself needs the tab open — closing before the progress bar reaches 100% cancels the upload. But once the upload finishes, all subsequent processing happens on Blended's servers, so you can safely close the tab.

Can I edit the notes without regenerating them?
Yes. Save commits your edits without touching the AI. Only Regenerate replaces them.
