Frequently asked questions about Cloudflare Stream
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 a 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?
Is there a limit to the amount of videos I can upload?
By default, a video upload can be at most 30 GB.
By default, 120 videos can be in the
downloadingstate at once. If videos are in
pendinguploadstates, they don't count towards this limit.
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.
Can I embed videos on Stream even if my domain is not on Cloudflare?
Yes. Stream videos can be embedded on any domain, even domains not on Cloudflare.
What input file formats are supported?
Users can upload video in the following file formats:
MP4, MKV, MOV, AVI, FLV, MPEG-2 TS, MPEG-2 PS, MXF, LXF, GXF, 3GP, WebM, MPG, QuickTime
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).
