Descript Adds Claude Opus 4.7 to Underlord for Faster Video Edits.

Descript announced support for Anthropic's Claude Opus 4.7 model in Underlord, its AI-powered editing assistant. The update promises faster performance and lower costs compared to the previous Claude Opus 4.6 model.

The integration means users can now leverage Claude Opus 4.7's improved capabilities directly within Descript's video editing workflow. Underlord, which launched earlier in 2025, allows creators to use natural language prompts to edit video and audio projects without touching a timeline.

Claude Opus 4.7 represents Anthropic's latest advancement in its flagship model line. According to Descript's announcement, the model delivers better results while reducing processing time and operational costs. For video creators working with Underlord, this translates to quicker turnaround times when generating edits through AI prompts.

The cost reduction is particularly relevant for creators producing high volumes of content. Video editing workflows that rely on AI assistance can rack up API costs quickly, especially when iterating on complex edits or working with longer-form content.

This marks the latest model addition to Underlord's capabilities. In previous updates, Descript added GPT 5.4 to Underlord's model picker, giving users flexibility in choosing which AI model powers their edits. The ability to switch between models lets creators optimize for different scenarios: some projects may benefit from Claude's reasoning capabilities, while others might perform better with OpenAI's latest offerings.

Underlord works by translating natural language instructions into precise edits within Descript's text-based editing interface. Users can ask it to remove filler words, add b-roll, generate captions, or restructure entire sequences without manually manipulating clips.

The tool has become central to Descript's pitch as an AI-native editing platform. By offering multiple state-of-the-art models, Descript positions itself as model-agnostic, letting performance and cost considerations drive user choice rather than locking them into a single provider.

The move comes as video editing tools increasingly compete on AI capabilities. Anthropic's Claude has gained traction among developers and creators for its nuanced understanding of complex instructions, making it well-suited for tasks like video editing where context and intent matter.

Descript continues to differentiate itself through its document-based editing paradigm, where video and audio files are edited as text transcripts. AI assistants like Underlord amplify this approach by letting users describe desired outcomes rather than executing technical steps.

The Claude Opus 4.7 integration is available now to Descript users with access to Underlord. Descript has not disclosed specific pricing changes related to the model switch, though the company's announcement emphasized cost efficiency as a key benefit.
