FAQ

You cannot download the exact input file that you uploaded. However, depending on your use case, you can use the Downloadable Videos feature to get encoded MP4s for use cases like offline viewing.

• By default, a video upload can be at most 30 GB.

• By default, you can have up to 120 videos queued or being encoded simultaneously. Videos in the ready status are playable but may still be encoding certain quality levels until the pctComplete reaches 100. Videos in the error, ready, or pendingupload state do not count toward this limit. If you need the concurrency limit raised, contact Cloudflare support explaining your use case and why you would like the limit raised.

• An account cannot upload videos if the total video duration exceeds the video storage capacity purchased.

Limits apply to Direct Creator Uploads at the time of upload URL creation.

Uploads over these limits will receive a 429 (Too Many Requests) or 413 (Payload too large) HTTP status codes with more information in the response body. Please write to Cloudflare support or your customer success manager for higher limits.

Yes. Stream videos can be embedded on any domain, even domains not on Cloudflare.

When HDR videos are uploaded to Stream, they are re-encoded and delivered in SDR format, to ensure compatibility with the widest range of viewing devices.

If you are producing a brand new file for Cloudflare Stream, we recommend you use the following settings:

• MP4 containers, AAC audio codec, H264 video codec, 30 or below frames per second
• moov atom should be at the front of the file (Fast Start)
• H264 progressive scan (no interlacing)
• H264 high profile
• Closed GOP
• Content should be encoded and uploaded in the same frame rate it was recorded
• Mono or Stereo audio (Stream will mix audio tracks with more than 2 channels down to stereo)

Below are bitrate recommendations for encoding new videos for Stream:

Videos are removed if the subscription is not renewed within 30 days.

If your website uses Content Security Policy (CSP) directives, depending on your configuration, you may need to add Cloudflare Stream's domains to particular directives, in order to allow videos to be viewed or uploaded by your users.

If you use the provided Stream Player, videodelivery.net and *.cloudflarestream.com must be included in the frame-src or default-src directive to allow the player's <iframe> element to load.

Content-Security-Policy: frame-src 'self' videodelivery.net *.cloudflarestream.com

If you use your own Player, add *.videodelivery.net and *.cloudflarestream.com to the media-src, img-src and connect-src CSP directives to allow video files and thumbnail images to load.

Content-Security-Policy: media-src 'self' videodelivery.net *.cloudflarestream.com; img-src 'self' *.videodelivery.net *.cloudflarestream.com; connect-src 'self' *.videodelivery.net *.cloudflarestream.com

If you allow users to upload their own videos directly to Cloudflare Stream, add *.videodelivery.net and *.cloudflarestream.com to the connect-src CSP directive.

Content-Security-Policy: connect-src 'self' *.videodelivery.net *.cloudflarestream.com

To ensure only videos from your Cloudflare Stream account can be played on your website, replace * in *.cloudflarestream.com and *.videodelivery.net in the examples above with customer-<CODE>, replacing <CODE> with your unique customer code. To find your unique customer code in the Cloudflare dashboard, go to the Stream page.

This code is unique to your Cloudflare Account.

If your website loads in a lot of player instances, PageSpeed Insights will penalize the JavaScript load for each player instance. Our testing shows that when actually loading the page, the script itself is only downloaded once with the local browser cache retrieving the script for the other player objects on the same page. Therefore, we believe that the PageSpeed Insights score is not matching real-world behavior in this situation.

If you are using thumbnails, you can use animated thumbnails that link to the video pages.

If multiple players are on the same page, you can lazy load any players that are not visible in the initial viewport. For more information about lazy loading, refer to Mozilla's lazy loading documentation ↗.
