The complete Sora 2 tutorial covering all capabilities is the reference to bookmark before the full rollout
The synchronized dialogue and sound effects being generated simultaneously with video rather than as a separate audio step is the production workflow change that most directly affects output quality for scripted content. A video where the audio was generated with the same prompt context as the video produces better synchronisation than audio added to a completed silent video.
The storyboard feature for planning multi-shot sequences before generating individual clips is the pre-production tool that addresses the most common quality failure in multi-clip AI video projects: inconsistency between clips that were not planned in relationship to each other.
The video generation models being available across both iOS and web is the platform accessibility that determines when and where you can work with it. Mobile generation for quick concepts and web for production-quality longer sessions is the natural workflow split.
The limited rollout requiring Plus or Pro subscription and an invite code means the real evaluation window for most creators is still ahead. The tutorial is worth watching now to understand what to test when access arrives.
