Synthesia

Synthesia is an AI video generation platform that allows users to create professional videos from text using AI avatars and voices. It offers features like AI video editing, screen recording, translation, and integrations with various platforms, primarily for training, marketing, and internal communications.

Synthesia offers an AI Screen Recorder that captures screen and voice, and automatically transcribes voiceovers, which aligns with multi-source recording and automatic subtitle generation. It also provides an AI Video Editor with templates, basic editing tools, and branding options. The platform supports instant export and multi-language subtitle support. While it doesn't explicitly mention 'automatic cursor tracking and dynamic zoom,' its AI-powered editing and focus on ease of use suggest it automates many tedious tasks. The core value proposition of creating polished videos quickly is strongly met.
