FAQ

What formats and quality levels are delivered through Cloudflare Stream?

Cloudflare decides on which bitrate, resolution and codec is best for you. We deliver all videos to industry standard H264 codec. We use to few different adaptive streaming levels from 360p to 1080p to ensure smooth streaming for your audience watching on different devices and bandwidth constraints.

Can I download original video files from Stream?

Video cannot be downloaded from Cloudflare Stream.

Is there a limit to the amount of videos I can upload?

Each account starts with a 500 GB weekly rolling upload limit, which means that videos uploaded in the past 7 days regardless of the day of week will be counted. This only includes original videos uploaded.

A video file can be at most 20 GB. Please write to Cloudflare support or your customer success contact for higher limits.

What frame rates (FPS) are supported?

Cloudflare Stream supports video file uploads for any FPS, however videos will be re-encoded for 30 FPS playback. If the original video file has a frame rate lower than 30 FPS, Stream will re-encode at the original frame rate.

If the frame rate is variable we will drop frames (e.g. if there are more than 1 frames within 1/30 seconds, we will drop the extra frames within that period).
