Your reviewers can upload video reviews inside the Review Widget. You have to enable this feature inside the Judge.me Product Reviews app, Settings > Review Widget > Widget Addons > Review Videos.
Review videos and pictures cannot be uploaded inside the in-email review form (because the SMTP email protocol doesn't allow this). Your reviewers will go to the product page with the pre-filled & pre-opened Review Widget to add a review video or review photos.
Videos are uploaded to our Vimeo Pro Account, that host and manage them, producing an excellent loading speed that doesn't consume your page`s hosting bandwidth, also: gets max compatibility, since it converts the video into all the formats necessary, and their HTML5 embedded player works great across all devices.
