Start with the goal of the video
Before exporting, decide whether the video is for an event screen, a family message, a social post, a classroom recap, or a product update. That choice affects slide length, music, text size, and final format.
Prepare the Google Slides deck
Use one idea per slide. For photo videos, avoid placing too many images on one slide. For product or business videos, make each slide readable without a presenter. Use large type, simple layouts, and enough contrast for phone screens.
Choose MP4 or GIF
MP4 is the best default for complete slideshow videos because it supports longer playback and music. GIF is better for short loops, silent previews, and lightweight snippets where sound is not needed.
Set slide duration
Photo-only slides can usually move faster than slides with paragraphs or detailed charts. A good rule is to preview the deck and ask whether a viewer can understand each slide without pausing.
Add music when it supports the purpose
Music can make family and event videos feel finished. Keep the tone appropriate: upbeat for birthdays and holidays, gentle for memorials, and neutral for business or classroom updates.
Render and review before sharing
After export, watch the video once from beginning to end. Check spelling, names, dates, image order, readability, music fit, and whether the ending feels complete.
Slides To Video is listed on the Google Workspace Marketplace as a Google Slides add-on for converting slides into MP4 video or GIF.
