July 2026 Summaries

Mux has introduced six new workflows designed to enhance video content management, including premium caption generation, audio dubbing, engagement analysis, thumbnail selection, caption editing, and scene segmentation. The premium captioning feature offers high-accuracy speech-to-text with options for speaker identification and word-level timestamps. Engagement insights analyze viewer data to highlight key moments of interest in the video, while audio translation enables dubbing into different languages. The best thumbnail selection uses a vision model to evaluate and suggest optimal frames based on factors like focus and branding fit. Caption editing allows for text corrections and profanity censorship, and the experimental scene segmentation divides videos into narrative parts. These workflows operate through a consistent API call structure and are available via the Mux dashboard or API, with billing based on asset duration and workflow complexity.
