FAQ
Common questions about turning PowerPoint into video.
You can use PowerPoint (.pptx) and PDF files. The method that reads your speaker notes aloud works with .pptx files.
Yes. Choose “Explain all pages” as the method, and AI writes a script from the slide content and makes a video that explains every page.
There are four methods. Besides "Speaker Notes," which reads what you wrote in your notes, you can choose "Explain all pages," where AI walks through every page in order, "Explain key points only," which narrows it down to the important pages, or "Specify script," which reads the script you wrote for each page.
You choose the character and voice before generating. After generating, you can change the speaker and speaking speed for each scene or edit the script in the editor.
Yes. The timeline editor lets you edit the script, captions, images, video clips, text, shapes, music, and sound effects. You can also type an instruction on the finished video's page to make a version with just that part changed.
Besides widescreen 16:9, you can choose vertical 9:16, square 1:1, and other aspect ratios to suit where the video will be used.
AI reads the content of each page and writes the script. You can also learn about making videos from slides on “Slides to Video”.
Each file can be up to 400 MB and 260 pages. The page limit depends on the "explanation detail" setting: the more detailed the explanation, the lower the limit.
It depends on the size of the file and the method you choose, but generation usually takes from tens of seconds to a few minutes. While it runs, the video's page shows the progress and an estimate of the time remaining.
Your slides can be shown in the video as page images, so you don't need to rebuild charts or layouts for video. You can add captions, text, and other elements on top of the pages in the editor.
