+### Live transcription Preview
+
+Live transcription is now in public preview and available for use in the West US 2 region.
+
+Live transcription is designed to work in conjunction with live events as an add-on capability.  It is supported on both pass-through and Standard or Premium encoding live events.  When this feature is enabled, the service uses the [Speech-To-Text](../../cognitive-services/speech-service/speech-to-text.md) feature of Cognitive Services to transcribe the spoken words in the incoming audio into text. This text is then made available for delivery along with video and audio in MPEG-DASH and HLS protocols. Billing is based on a new add-on meter that is additional cost to the live event when it is in the "Running" state.  For details on Live transcription and billing, see [Live transcription](live-transcription.md)
+
+> [!NOTE]
+> Currently, live transcription is only available as a preview feature in the West US 2 region. It supports transcription of spoken words in English (en-us) only at this time.
+
+### Content protection
+
+The *Token Replay Prevention* feature released in limited regions back in September is now available in all regions.
+ Media Services customers can now set a limit on the number of times the same token can be used to request a key or a license. For more information, see [Token Replay Prevention](content-protection-overview.md#token-replay-prevention).
+
+### New recommended live encoder partners
+
+Added support for the following new recommended partner encoders for RTMP live streaming:
+
+- [Cambria Live 4.3](https://www.capellasystems.net/products/cambria-live/)
+- [GoPro Hero7/8 and Max action cameras](https://gopro.com/help/articles/block/getting-started-with-live-streaming)
+- [Restream.io](https://restream.io/)
+
+### File Encoding enhancements
+
+- Improved performance and multi-threading for the re-sizer in Media Encoder Standard. Under specific conditions, customer should see a performance boost between 5-40% VOD encoding. Low complexity content encoded into multiple bit-rates will see the highest performance increases. 
+- Standard encoding now maintains a regular GOP cadence for variable frame rate  (VFR) contents during VOD encoding when using the time-based GOP setting.  This means that customer submitting mixed frame rate content that varies between 15-30 fps for example should now see regular GOP distances calculated on output to adaptive bitrate streaming MP4 files. This will improve the ability to switch seamlessly between tracks when delivering over HLS or DASH. 
+-  Improved AV sync for variable frame rate (VFR) source content
+
+### Video Indexer, Video analytics
+
+- Keyframes extracted using the VideoAnalyzer preset are now in the original resolution of the video instead of being resized. High resolution keyframe extraction gives you original quality images and allows you to make use of the image-based artificial intelligence models provided by the Microsoft Computer Vision and Custom Vision services to gain even more insights from your video.
