Frequently Asked Questions
How many images can I add?
No hard limit — browser memory is the ceiling. For most setups 50+ images work fine at 1080p.
What is Ken Burns?
Slow zoom/pan over each still image — gives a cinematic feel. Named after the documentary filmmaker who popularised the technique.
Can I add music?
Not in this tool. Build the slideshow here, then use the Audio Replacer tool to attach a music track.
Why is the render slow?
Each slide becomes a short video clip and everything is re-encoded with H.264. 20 slides at 3 seconds each is ~1 minute of output — expect 30-60 seconds on an M-series Mac, longer on older hardware.
