Turn a PowerPoint deck into a presentation video automatically

Find your way around the Slides and script screen

Slides and script is where you spend most time: slides on the left, the selected slide in the middle and its lines on the right.

The example is a five-slide briefing deck on the benefits of a generative-AI chat platform for small and midsize companies. It is a sample report produced by DeepResearch in Bestllam (https://bestllam.com), our own service, loaded as it is. The presenter is Sophia.

The figures from the second onward show the screen after lines were split in a later tutorial. Before splitting, each slide holds one long line as in the first figure.

BEFORE YOU START

Before you start

Prepare the PowerPoint file (.pptx) you want to turn into a video and open the MotionVox home screen. The tutorials in this chapter follow the same five-slide deck.

Screenshots show actual sample projects. Instructions describe desktop browser operation; this guide can also be read on a phone.

STEP01

Read the script for each slide

When every slide shows Audio ready, review the content. Select a slide on the left to see its appearance in the centre and its script on the right.

  1. Click the slide you want to review.
  2. Check how the slide, presenter and captions look in the centre.
  3. Read the script on the right. Always check numbers and names against your slides yourself.
  1. Action Click the slide you want to review.
  2. Check Check how the slide, presenter and captions look in the centre.
  3. Check Read the script on the right. Always check numbers and names against your slides yourself.
Step 4 with the script and narration ready for slide 1.

Check In this example the script was a spoken-style explanation based on the slide text. Slide 1 was a single 17.8 second line beginning with a greeting. Estimate at the upper right shows the expected total length.

STEP02

Left and middle: slide list and preview

On the left and in the middle you select a slide and check how it looks.

  1. Click a slide in the list. Each has Saved and Audio ready badges; with both, its script is saved and its narration exists.
  2. Check the slide, presenter and caption in the preview. The Fit (36%) control below changes the zoom from 50% to 300%.
  3. The buttons under the preview play and stop this slide’s narration (sound will play). The right end shows the position and the slide length, 00:00 / 00:28.
  4. The strip at the bottom shows when each emphasis appears as red clips. The numbers on the left are line numbers.

Step 4, Slides and script: slide list on the left, preview in the middle and the four lines of slide 1 on the right.

Check Slide 1 of this example has four lines, 28 seconds in total. Adjusting emphasis is covered in “Emphasize key parts of a slide”.

STEP03

Right: what each line shows

On the right, the lines of the selected slide are listed in speaking order. Each line becomes one speech clip in the video.

  1. Each line shows its number and length (Line 1, 1.5 seconds) with the spoken text below. Click the text to rewrite it in place.
  2. The three buttons at the lower left play, pause and stop just that line (sound will play).
  3. Add emphasis adds an emphasis to the line. On our screen the button was red on lines that already had one.
  4. Details opens settings for that line only, such as reading speed, caption text and body motion.
  5. + Add line adds a line to this slide. At the upper right of each line are arrows to move it up or down and a bin to delete it.
