Extra-Fast Publishing

by Assaf

A popular requirement for news websites and video publishers is to publish videos as quickly as possible. Kaltura allows publishers to control video asset readiness by allowing them to configure the transcoding settings to their needs.

Kaltura’s platform supports ingestion of all forms of rich media (including video, images, audio, PDF, SWF files), and allows publishers to define different transcoding profiles, depending on the publishing needs. Additional transcoding flavors can easily be added for publishing across different devices. Kaltura’s transcoding decision engine supports more than 60 video and image formats as well as 140 video and audio codecs.


When a video is uploaded to Kaltura, the video is associated with a conversion profile, also known as a Transcoding Profile. A Transcoding Profile may be comprised of a single flavor or multiple flavors. For each upload session, you can select the Transcoding Profile. You can also set a default Transcoding Profile.

After uploading, the status of a video entry will not be ‘Ready’ for publishing until all of the required flavors are created. If multiple flavors are included in the profile, the conversion process may take awhile, which is sometimes not fast enough for breaking news videos.

Kaltura enables you to configure whether a certain video’s flavor is required or not for the entry itself to be ready.

For example, assuming the source flavor is a ‘playable’ entry created using h264 for web and mobile, you can configure h264 as required, and all other flavors as optional. The video will be ready for publishing immediately after the upload is complete. The other flavors are processed, created, and added to the entry in the background.
