For best results, optimize your video for streaming before uploading. Learn more about optimising video for webinar streaming.
Choose a video hosting service
The streaming service you choose should provide a direct MP4 playback URL.
Supported options include
- Kartra direct MP4 links (unlimited hosting on Starter and above)
- Vimeo direct MP4 links (third-party playback is available on select paid plans)
- Amazon S3 or a similar file-hosting solution
- Similar solutions must offer a direct MP4 playback URL for the hosted video.

Hosting video with Kartra
Kartra third-party playback is available on all paid Kartra plans.
Access Kartra links:
- In your Kartra account, go to Media center > Videos
- Locate the video and click the three dots on the asset tile
- Select Get video in the menu
- Select Source file URL

- Copy the complete URL from the Source file URL field
- Paste it into your WebinarJam or EverWebinar configuration
Hosting video with Vimeo
Vimeo third-party video playback is available on select paid Vimeo plans.
Direct links to a Vimeo-hosted video allow MP4 playback with logo removal and the ability for EverWebinar to override the native playback controls.
Access Vimeo links:

From the video links pop-up:
Select "Play the video" from the dropdown menu
Choose one of the MP4 options and click "Copy link" (the HLS and DASH formats are not compatible with WebinarJam)
Paste the link into the WebinarJam video injection field or as an EverWebinar source video and Save.

Note: When selecting a video link from the menu shown above, choose your preferred playback quality.

Hosting video with Amazon S3
To use a video hosted on Amazon S3 with WebinarJam or EverWebinar:

- Copy the video's MP4 file path to paste into the WebinarJam or EverWebinar configuration
Upload the video file to Amazon S3 and use Actions > Make public to change the permissions:

Get the Object URL for the MP4 file:

Amazon S3 Notes
Some visitors may experience buffering with Amazon S3 video streaming. To improve streaming performance, host your video on Amazon S3 and stream it via Amazon's CloudFront.
- Convert the S3 video file URL into a CloudFront URL to use it in your webinar configuration.
- See Amazon's S3 to CloudFront conversion wiki article for conversion instructions.
- Paste CloudFront URL into your WebinarJam or EverWebinar configuration to use it as a source file.
Hosting EverWebinar source video with YouTube
YouTube is a free video hosting option that is compatible with EverWebinar.
Important: YouTube's legal terms and conditions do not allow the removal of the YouTube logo or video player controls. This means that it is not possible to restrict the playback controls in an EverWebinar event and videos hosted on YouTube will always show their logo in the lower right corner of the playback window.
To use a YouTube-hosted file for your webinar:
- Visit the dedicated page for your video on the YouTube website
- Copy the YouTube page URL and paste it into the EverWebinar configuration
- Note: The "share" link for the YouTube video will not work. You must use the full page URL.
