Use a simple chapter structure
Start with opening title, then early years, couple milestones, friends and family, and a short closing message. This keeps the flow clear.
Limit slide count
More photos is not always better. A focused slideshow usually gets stronger reactions than a long photo dump.
Optimize for venue playback
Export to MP4 so the file plays smoothly without depending on internet, permissions, or live presentation mode.
Preview on a bigger screen
Before event day, test your file on a laptop or TV to catch tiny text, dark photos, or sudden pacing issues.
Google Slides is great for collaborative editing, and Slides To Video handles the final export step.
