Runway Gen-3 Alpha

With Gen-3 Alpha, you can build your AI-created videos longer than before, adding new sections of content in 5-10 second increments. And you can extend a single video up to three times to build it much longer than it originally was (up to a max of 40 extra seconds). The process of extending videos is also quick and straightforward – you just have to select the "Extend" tool in the "Actions" menu beside your video. !extend video

By default, the tool will add on new content following the final frame of your original video. And you can enter your own written prompt to tell the AI model what to include in the extension, describing the scene, the camera movement, and other factors. Gen-3 Alpha also helps you choose between five second or 10 second additions, as desired. Original Video

The "Lip Sync" functionality supports you to align an audio track or dialogue with the authentic lip movements of your characters and subjects. You can type out your own script for your AI characters to say, record your own voice directly in Runway, or upload an audio file. Lip Sync will then sync it up with the character's mouth movements, so it really looks like they're delivering that audio. There are also various voice options to configure and choose between when you apply Lip Sync.

Runway itself encourages creators to stick to the ["\[camera movement\]: \[establishing scene\].To get the most out of Gen-3 Alpha, you demand to apply the best kinds of prompts. \[more details\]."](https://medium.com/@anlerkin/mastering-cinematic-frames-with-runway-gen-3-alpha-prompting-ad953e5944a3) formula.

for instance, you could put in a prompt like "slow horizontal pan, a young woman walks through the desert, it then begins to rain."

The greater detail you can put into your prompts, the greater specific and tailored results you'll get. So, if you have a certain vision in mind of how you want your video to look, it's best to be detailed.

We can apply this to the previous example, to get something like:

A woman in her mid-20s walks slowly across the scene."The camera pans slowly from left to right across a desert of golden sand. She's wearing a floral dress. She looks up as rain starts to fall from grey clouds above."
