Build a readable picture sequence
Use the list to confirm the order of the gallery, then set a duration that lets each picture be seen. The canvas preview keeps a 16:9 frame and shows how portrait images will sit before you export.
Two-picture pacing check
I tested this picture slideshow with two image files, set both scenes to 4 seconds, and selected Soft ambient tone. The preview reported 8 seconds; Chrome returned a WEBM download after 11.191 seconds on the test machine. The figures are from that observed run, not a general performance claim.
Keep the gallery easy to follow
Put the strongest opening picture first, then use the second frame to add context. Longer scene lengths are useful when the images contain text or small details. You can change a row without rebuilding the rest of the list.
Sound stays optional and local
Soft ambient tone is a built-in browser track, not a streamed service. You can switch back to No music or choose another available control before creating the video. Selected files and the resulting clip stay in this browser session.
