Short clip resizing and delivery for websites and web applications

Video Optimisation is powered by Visual Operations Credits; full details on consumption rates can be found here: Visual Operation Credits table

Cloudimage offers on-the-fly video processing with delivery via CDN using the Cloudimage 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, 4k resolution and maximum 60 seconds length. For longer videos, only the first minute will be optimized and delivered, resulting in a trimmed video.

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

Available Parameters

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)
