eWebinar supports most common video sources. When you create an eWebinar you can add your video in four ways:
- Paste a video URL from a supported host: YouTube, Vimeo, Wistia, Amazon S3, Descript, and most other major hosts. eWebinar imports the video file into its own Vimeo-backed pipeline. Note: YouTube has made direct imports more restrictive over time: if the URL fails, download from YouTube and upload the file directly.
- Upload from your computer in any common format: MP4, MOV, WMV, AVI, and others supported by Vimeo.
- Import from Zoom if you've connected the Zoom integration. You'll see a picker listing your recent cloud recordings.
- Publish from Descript: from Descript's publish menu pick eWebinar and the rendered video is sent straight into a new webinar (see Descript integration).
Limits and best practices
- The upload limit is 2 GB per file. At 720p (our recommended resolution) that's roughly two hours.
- If you need a larger file, use the Vimeo integration to host the source in your own Vimeo account instead.
- Use 720p for most webinars: it's the best balance of quality and bandwidth for live streaming over diverse internet connections. 1080p is fine if your audience is mostly desktop on good connections.
- Captions are generated automatically once the video finishes transcoding. See automatic transcription and captions.
Whatever source you start from, eWebinar re-hosts the video through Vimeo internally so playback, seek behavior, and CDN delivery are consistent across browsers and devices.
