On-the-fly video optimization

Short clip processing and delivery for websites and web applications

Please contact the support team to activate the video feature for your token.

Filerobot offers on-the-fly video processing with delivery via CDN using the Filerobot URL for seamless integration. This feature is suited for short clips for websites and web applications such as hero videos or product videos.

Input files are limited to 500 MB and compressed videos are limited to 4k resolution and duration of no more than 1 minute. If your videos exceed those limits, your use case probably does not fall into the scope of this feature and you should consider using Upload post-processes and Video API.

The video files processed in the URLs need to have the proper file extension (eg. .mp4, .webm).

Available parameters

//token.filerobot.com/folder/origin_video.mp4?w=600&format=auto

Parameter	Allowed values	Description
w	>100	Sets the target video width
h	>100	Sets the target video height
func	crop (default) | fit | cropfit | bound | boundmin | cover	Sets the resize function if both width and height parameters are provided
bg_color	hex color code / color name	Background (padding) color (for use with func=fit)
