Making a video quiz without filming a new video

Teachers and tutors who record a lesson often want a video quiz to check what viewers actually took away, and that starts with good questions tied to the lesson content.

  • Upload notes, slides, or a transcript that matches the video.
  • Mix multiple-choice and true/false questions to check recall quickly.
  • Read each explanation and adjust questions that don't match the clip.
  • Keep quizzes short enough to finish right after the video ends.
Example fractions and decimals quiz questions
What is 3/4 written as a decimal?0.75. Divide the numerator by the denominator: 3 ÷ 4 = 0.75.
True or false: 0.6 is equal to 3/5.True. 3 ÷ 5 = 0.6, so the two values are equal.
Which is larger, 2/3 or 0.65?2/3. It equals about 0.667, which is greater than 0.65.
What is 1/8 as a decimal?0.125. Dividing 1 by 8 gives 0.125, so one eighth equals 0.125.
Add 1/4 and 0.5. What is the sum?0.75 (or 3/4). Convert 1/4 to 0.25, then 0.25 + 0.5 = 0.75.

Works from your material

Upload a PDF, DOCX, PPTX, plain text file, or a photo of a page. Text in images is read with text recognition.

Questions with explanations

Each question comes with an explanation, so viewers learn why an answer is right or wrong, not just whether it is.

Study in the browser

Take the quiz right after the video or share the link. The free plan includes 3 generations per month.

How it works

Upload your material

Add the slides, transcript, or notes that match the video you want to check.

Choose question types

Pick multiple-choice, true/false, or open questions, then generate the set.

Review and pair with your video

Edit anything that doesn't fit, then place the quiz after the clip. Export to PDF or DOCX on Plus or higher.

A simple workflow works well: write or export your lecture notes, upload them, then review the generated questions against the moments in the recording where each idea appears. Short, specific questions are easier to answer after a clip than broad ones.

If you need exports for a learning platform, Plus includes PDF, DOCX, Anki, and CSV, and Pro adds QTI 2.1 and Moodle XML.

Frequently asked questions

How many questions should a fractions and decimals video quiz have?

Five to eight questions work well for a single short lesson on fractions and decimals. This keeps the quiz focused and lets viewers check the key conversions before moving on.

Should a fractions and decimals quiz mix question types?

Yes, combining multiple-choice questions with true/false checks helps separate quick recall from understanding. Include at least one question that asks for a conversion, such as writing 3/4 as a decimal.

Does DeckOwl create the video itself?

No, DeckOwl creates quiz questions from your own material and does not record or edit video. You place the quiz alongside whatever video you already have.

Can I export the quiz?

Exports are paid features: Plus includes PDF, DOCX, Anki, and CSV, and Pro adds QTI 2.1 and Moodle XML. The free plan lets you study in the browser without exporting.
