Does this validate Walmart Marketplace requirements?
No. This is a practical seller utility for short product showcase videos, not an official Walmart validator.
Can I change the preset after upload?
Yes. The clean catalog-style sequence is only the starting point. The root tool controls remain available after upload.
Is export still local-only?
Yes. Preview and export stay in the browser without server-side video rendering.
Does Walmart Marketplace support product video?
Yes, as a rich media asset attached during item setup. It supplements the image set rather than replacing it, and the primary image still has to meet Walmart's white background and minimum-size rules.
What resolution should the video be?
1920 x 1080 at 30 fps is the largest this tool produces and is a safe target for a listing video. It renders at roughly 8.5 Mbps, which keeps the file clean without being unmanageably large.
Can the video include prices or promotions?
No. Walmart's content rules prohibit promotional text, pricing claims and competitor references in listing content. Keep the on-screen headline descriptive.
Why is the default motion set to still?
Because Walmart's listing presentation is plain and its rules are conservative. A static sequence with fades reads as product documentation rather than as an ad, which is the register Walmart's page is written in.
Where does the rendering happen?
In your browser. Frames are drawn on a canvas and encoded through WebCodecs or MediaRecorder, so nothing is uploaded.
