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 2048 GB weekly rolling upload limit (videos uploaded in the past 7 days regardless of the day of week will be counted.) This only includes original video files uploaded.
By default, a video upload can be at most 20 GB.
By default, 70 videos can be in the "in progress" state at once.
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.

Users can upload video in the following file formats:

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).
