Is this only for Facebook Marketplace?
No. It is the same root tool, but the page copy and default preset are tuned for Facebook Marketplace-style product videos.
Can I switch to portrait or landscape?
Yes. This page opens with a square preset, but the normal canvas controls remain available inside the tool.
Does export stay local?
Yes. Preview and export remain in the browser, so the source product images do not need server-side video rendering.
Can I add a video to a Facebook Marketplace listing?
It depends on the category. Marketplace is photo-first, and video slots are not offered everywhere. If your listing has no video slot, post the clip to your feed or a local group with a link to the listing instead.
What size should the video be?
Square 1080 x 1080 is the default here, matching the 1:1 tile the Marketplace grid crops to. Portrait 1080 x 1920 is better if the clip will be posted as a Reel.
Does the video have sound?
No. The renderer produces a video track only. That is fine on a silent-autoplay listing surface and a real handicap in a Reels feed, where sound and captions do the work.
When is a video actually worth making for Marketplace?
For bundles, clearances and anything with a lot of parts. Fifteen seconds showing eight items beats making a buyer swipe through eight photos, and the same file can be reposted to a local group.
Is the video uploaded anywhere during rendering?
No. The frames are drawn and encoded in your browser and the file is downloaded directly.
