# Transcription and translation transforms MK.IO offers AI-powered VOD transcription and VOD translation features that allow you to generate subtitles from audio tracks. The generated subtitles are delivered in WebVTT format into an output asset and can be subsequently added to the manifest of the asset with a [track insertion transform](/mkio/reference/encoding-transform-presets/add-a-track-to-a-vod-asset). > **Info:** On-demand transcription and translation are only available for MP4 assets. ## VOD transcription MK.IO provides a built-in preset, **Predefined\_ACSVodTranscription,** to be used in such AI workflow transform for VOD Transcription. When selecting this VOD transcription preset, all you need to do is specify the original language of the audio track using the BCP-47 format. It is also possible to provide a list of words or phrases that are expected in the audio feed in order to improve their recognition.
