Turn Your Slides into a Video

Use the Transform button in Google Slides to turn a deck into a narrated video in Google Vids, then make it yours: rewrite the script, give a slide its own voice, switch a scene into Arabic, and fix the music. The demo uses the Grade 10 English deck from Station 2.

Before you start
  1. Open a Google Slides deck you've already checked. A video can only be as accurate as its slides.
  2. Bring headphones so you can listen to the voiceover at your desk.
  3. Keep student names, photos and voices out of the deck and the script.

Make the video with Transform

One button sends your slides to Vids. Gemini writes a script for each slide, adds a voiceover, background music and simple animations, and you can edit the script before it builds anything.

    Choose the slides

    Every slide starts ticked. Untick any you don't want in the video, such as an image credits slide or a long activity slide.

    Leave Include AI voiceover, script, background music and animation switched on, then click Next.

    Shorter is better. Aim for 4 to 8 slides. Our 10 slides made a video of almost two minutes.
  3. One script box per slide. Click any box to edit it.

    Read and rewrite the script

    After a few seconds Gemini writes a script for each slide. This is the easiest place to fix it, before any audio is made.

    Click into a box and type over it. In our demo we replaced a formal opening with one written for our own class.

    Write for the ear. Short sentences, your students' names for things, and no more than two or three sentences per slide.
  4. Press play to hear the narrator. The pencil changes the voice for the whole video.

    Choose the narration, then create

    Under Narration, choose Voiceover only or AI avatar and voiceover. Scroll down to hear the narrator and check Animations is on.

    Click Create the draft video. It takes about a minute.

  5. 5

    Meet your draft

    The video opens in the Vids editor. Each slide is a scene along the timeline. Underneath are:

    • Green bars: text that animates in.
    • A long music bar: the background track.
    • One voiceover clip per scene, labelled with its first words and the voice.

    Click Play at the top to watch it all the way through.

Part 2 · AI voiceover panel

Change the script, the voice and the language

Every scene has its own voiceover, so you can rewrite one slide, give a quotation its own voice, or switch one scene into Arabic without touching the rest.

30+ voicesArabic and 20+ other languagesChange one scene or all
  1. 1

    Open the AI voiceover panel

    On the timeline, click the voiceover clip for the scene you want to change. A small toolbar appears. Click the first icon to open AI voiceover.

    Or click Voiceover in the right-hand menu. Use the arrows next to Scene 2 / 10 to move between scenes.

  2. 2

    Rewrite a scene's script

    Click into the script box, select the text and type your own. The scene is marked Voiceover outdated until you update it in step 4.

    Our demo: By the end of this video, you'll be able to spot the three persuasive appeals, explain how they make an audience feel, and judge which one works best.
  3. 3

    Give this slide its own voice

    Under Voiceover, click Change. Press play to preview voices, click the one you want, then Select.

    With Current scene selected, the new voice applies to this slide only.

    Use it for a reason. A second voice works well for a quotation, a counter-argument, or a "student" asking a question.
  4. 4

    Update the voiceover

    Click Update voiceover, then Replace. After a few seconds Voiceovers were successfully replaced appears and the clip on the timeline shows the new script and voice.

    One scene or all? Current scene changes one slide. All scenes shows every script and has Update all voiceovers. Use it when you want one voice for the whole video.
  5. Click the globe next to Voiceover to see the supported languages.

    Switch a scene into Arabic

    The voice speaks whatever language the script is written in. To change the language:

    • Translate the script, for example with Translate text in the Classroom Gemini tab (Station 1).
    • Paste the translation over the English script.
    • Click Update voiceover › Replace.
    Get a second listener. Ask an Arabic-speaking colleague to check the translation and how the voice says it. The text on the slide itself stays in English unless you change it.
Part 3 · Sound

Change the music or turn it down

The draft comes with a stock music track that can compete with the voice. Turn it down, make it duck under the narration, or create a new track that fits your subject.

Volume per trackAutomatic duckingGenerate new music
  1. 1

    Lower the music volume

    Click the long music bar at the bottom of the timeline, then the speaker icon that appears. In the Sound panel, drag the Volume slider or type a number and press Enter.

    Try 20 to 30%. Students should hear the music start, then forget about it. Tick Mute to remove it completely.
  2. 2

    Let it duck under the voice

    Scroll down the Sound panel to Automatic ducking. For music, choose Background: the music dips whenever the voiceover speaks and comes back up in the gaps.

    The draft music in our demo already had Background set. Music you add yourself may not, so check this every time.

  3. 3

    Create new music

    Click Music in the right-hand menu. Describe the mood and instruments, open the settings to switch on Instrumental, and click Generate.

    Our demo prompt: Calm, focused background music for a high school English lesson video. Soft piano and light strings, steady tempo, nothing distracting.

    Press play to listen. If it's wrong, click Recreate.

  4. 4

    Swap the old music for the new

    1. Click the old music bar and press Delete.
    2. Click the time under the preview so the playhead jumps to 00:00.0.
    3. In the Music panel, click Insert.
    4. Click the new bar, then the speaker icon. Set ducking to Background and volume to about 30%.
    Watch the playhead. Insert puts the music wherever the playhead is. If it lands halfway through, press Ctrl+Z and try again.
Part 4 · Share

Get it to your students

The video saves itself to your Drive as a Vids file. Share it like any Drive file, or download an MP4.

  1. 1

    Share or download

    • In Classroom: attach the Vids file from Drive to a Material or Assignment, like a Doc or Slides.
    • As a file: File › Download › MP4 video.
    • To Drive as a video: File › Export to Drive.
    Name it first. Vids names the file after your deck. Rename it so students can find it, for example Persuasion recap – Grade 10.
Your station challenge · 15 minutes

Make a 60 to 90 second recap video

  1. Use the deck you built at Station 2, or any checked deck. Keep 4 to 6 slides.
  2. Rewrite the first slide's script so it sounds like you talking to your class.
  3. Give one slide a different voice, or switch one slide into a language your students speak at home.
  4. Set the music to Background ducking and about 30% volume. Watch it all the way through with headphones.
Before students watch it

Check it

Listen to every scene

AI voices can mispronounce names, Arabic terms and abbreviations. Rewrite the script spelling if a word sounds wrong.

Check the script matches the slide

Gemini writes the narration from your slides. Make sure it says what the slide shows and nothing extra.

Check translations

Have a fluent speaker check any non-English scene before it reaches students or families.

Keep it short

Under two minutes holds attention. Cut slides rather than speeding up the voice.
