What is Transcoding?
When you upload a video in Skykit Beam, it goes through a two-step process: first the video is uploaded into the system, and then it is transcoded. Transcoding converts the video to a standardized specification to ensure reliable, predictable playback across all your devices.
Beam converts videos using the VP9 codec, which creates substantially smaller files with little to no visible difference in quality. This compression enables smoother streaming to a variety of devices and is supported by most major technology companies.
A few notes on the transcoding process:
It happens automatically: Beam transcodes video files by default.
If creates your preview: The process also generates the thumbnail/preview image of the video that shows in Skykit Beam.
It takes time: Transcoding can take a few minutes or even longer for larger video files. This is why your video might not be available immediately after it’s been uploaded. You can track the progress of the transcoding process in the Notifications drawer in Beam.

Why Do We Do It?
The reasons for transcoding boil down to predictability and efficiency. Rather than trying to enhance the original video's quality (since output can never be better than the source file), transcoding ensures consistent encoding parameters. This guarantees that your files are smaller for faster loading and that playback works reliably on almost any device or screen.
Do Videos Have to Be Transcoded?
Skykit Beam transcodes videos automatically, but you can choose to turn transcoding off.
Disabling Transcoding for Individual Videos
At Initial Upload
When uploading your video, use the toggle to disable transcoding for your video file(s). If you do choose to skip this process, however, we strongly recommend that your source video is saved as an MP4 file with H.264 video and AAC audio. (Note: You will also want to ensure your target resolution, frame rate, and bitrate are optimized for your specific displays, such as 1080p vs. 4K).
At Re-upload
The transcoding toggle is also available when re-uploading a video on the content detail page in Skykit Beam. To do this:
Open the detail page of your video content
Click the icon to choose an upload source of local storage or OneDrive
Choose your file
Toggle off the transcoding option
Disabling Transcoding by Default
If you would like to change the default setting of the upload toggle to off, support@skykit.com.
The transcoding toggle will remain available on your upload screen even if the default is changed, allowing you to manually transcode specific video uploads when needed.
