Why build the quiz from your own material

Creating a video quiz in Kaltura starts with the material behind the lecture. When questions come straight from your slides or notes, they test what you actually taught rather than generic trivia, and the wording matches the video.

Start with slides or notes that cover the same topic as the video.
Mix question types so viewers face multiple-choice and true/false items.
Read every explanation and edit anything the lesson does not support.
Keep the final quiz short enough to match the video length.

Example cell biology quiz questions (sample topic)

Which organelle is the main site of ATP production in eukaryotic cells?The mitochondrion. Its inner membrane hosts the electron transport chain that drives most ATP synthesis.

True or false: plant and animal cells both have a cell wall.False. Only plant cells have a cell wall, made mainly of cellulose, while animal cells rely on the plasma membrane alone.

What does the Golgi apparatus do?It modifies, sorts and packages proteins and lipids for transport. Materials arrive from the endoplasmic reticulum and leave in vesicles.

What is the role of the nuclear envelope?It keeps the DNA separate from the cytoplasm, while nuclear pores control what passes between them.

What is the function of ribosomes?They build proteins by translating mRNA into a polypeptide chain. Free ribosomes make proteins used inside the cell, while bound ones make proteins for export or membranes.

Generate the full set

Questions from your own material

Upload a PDF, PPTX, DOCX, text file or photo of a page, and get multiple-choice, true/false or open questions based on that content.

Explanations for every answer

Each question comes with an explanation, so viewers who miss an item can see why the correct answer is right.

Export for your course platform

Pro exports QTI 2.1 and Moodle XML, and Plus adds PDF and DOCX for handouts. Ask your administrator which format your Kaltura setup accepts.

How it works

Upload the source

Add the slides or lecture notes that match the video, or a photo of the page if that is what you have.

Generate and review

Choose question types and check each item against the video content before you publish it.

Add to the video

Enter the questions in your Kaltura quiz tools, or import a QTI 2.1 file on Pro if your platform supports it.

DeckOwl does not publish to Kaltura on its own. You generate and edit the questions here, then place them in the Kaltura tool your course uses. Keeping the review step in your hands means you can correct wording and remove anything that does not fit the lesson.

Free accounts get three generations a month and study in the browser, but exports need a paid plan. Plus is $99.90 a year or $9.99 a month, and Pro is $14.99 a month for QTI 2.1 and Moodle XML. Students get 40% off with a school email, and no credit card is needed to start.

Frequently asked questions

How many questions should a video quiz have?

Most short lecture videos work well with three to six questions placed at natural breaks. Longer lectures can take more, as long as each question checks a single idea from that segment.

What makes a good quiz question for a cell biology lecture?

Good items test one fact or relationship, such as what an organelle does, and offer plausible wrong answers. Avoid questions whose answer appears word for word in the slide title.

Can I export my quiz to Kaltura directly?

DeckOwl does not connect to Kaltura directly. Pro exports QTI 2.1 and Moodle XML, and you can check whether your Kaltura setup accepts those files.

Is there a free way to try it first?

Yes, the free plan includes three generations per month and in-browser study, with no credit card needed. Exports require Plus or Pro.
