Yes — Storyblok supports video uploads as assets. The maximum file size depends on the asset limits included in your subscription plan.
That said, many teams prefer hosting videos on dedicated platforms like YouTube or Vimeo, which offer better performance, adaptive streaming, and no impact on your Storyblok storage limits.
If you do upload directly, your videos will count toward your project's asset and storage usage. Note that some configurations may restrict certain file types — check your asset type settings if you run into issues.
