On the free plan, videos you add in the web editor stay on your computer, and only a light 720p copy uploads.
Edit at full quality
On your computer the editor plays the original, and your export uses it.
Relink a moved clip
A clip whose file is missing shows Offline · Relink. Choose the folder that holds it, and Klipeo matches files by their contents, even after a rename.
Know before you export
The export panel tells you when offline clips would export at 720p.
