You can now use the YouTube API to access and create captions for your videos. That means you could let your site visitors refine the transcript to videos you own, or create their own versions of the caption.
When the Netflix API turns three in October, it will also be making some big changes. With a focus on the quickly growing streaming service, Netflix will remove access to its DVD-related API calls. That means any websites or mobile apps that help organize your DVD queue will switch to only providing results that are available on its Netflix Instant streaming service.
