We've updated the Transcode API, Music Mastering API, and Enhance API.

Transcode API

New features

We have introduced Text as an output overlay type. You are now able to burn in text as a visual watermark over your video. The same position controls and fade-on/off controls exist to match the image overlay feature. Please refer to our How to Create an Overlay guide for usage and examples.

Improvements

The image overlay feature has been extended to streaming output formats such as HLS and Dash. You are now able to place images or text (or both) over these formats. The Transcode API will scale the overlays for each output layer in the HLS or Dash ladder. Please refer to our How to Create an Overlay guide for usage and examples.

Bug fixes

Using the segment parameter with Dolby.io Media Temporary Cloud Storage to trim an input media file is now correctly applied.

Music Mastering API

New features

We have introduced output file format selection for the Music Mastering API. You are now able to specify the output container (for example, MP3, AAC, WAV) of your music master. Please refer to our How to specify the output file format of your music master guide for more info.

Improvements

Stereo image metrics are now part of the Music Mastering Preview Metrics feature. Stereo image metrics inform you about the input music track's stereo width within the low, mid, and high frequency bands. Please refer to our How to understand Music Mastering Preview Metrics guide for more info.

Enhance API

Improvements

Content-Type (MIME type) is now automatically set for all outputs for the Enhance API when using credential-based storage for Azure, Google Storage, and S3 instead of the generic 'application/octet-stream' content type. This allows browsers to display files that are natively supported. If you are using signed upload URLs, please note that the content-type must be set when creating the signed URL before calling the Enhance API.
