FAQ
Is my video uploaded to a server?
No. Reading, seeking, frame capture, sheet layout, and image download all happen in your current browser.
How are the thumbnail frames selected?
The tool avoids the very beginning and end, where blank frames are common, and selects the requested number of frames evenly across the remaining duration.
What information appears on the generated sheet?
The header always shows the customizable video name, duration, resolution, and file size. Each frame can show a timestamp, and a SodaTool watermark is fixed at the bottom right.
Should I choose PNG, JPG, or WebP?
PNG is lossless but usually larger. JPG offers the broadest compatibility, while WebP often keeps good visual quality at a smaller file size.
