Outlines
๐๏ธ Introduction to Generative Audio
This paragraph introduces the topic of the video, which is generative audio in Runway Academy. It covers text-to-speech, custom voice models, and creating lip-sync videos. The speaker explains how to access the generative audio tool from the dashboard, input text, and select a voice from the default list. The process of generating audio from the script is described, including the automatic saving of audio files to the assets folder and the option to save them elsewhere. The paragraph also mentions the possibility of training a custom voice model using a few minutes of clean audio.
๐ Custom Voice Model Training
The second paragraph delves into the process of training a custom voice model within the generative audio tool. It details the requirement of having a few minutes of clean audio, which can be imported or recorded directly in Runway. The speaker suggests reading from the provided script or using one's own, emphasizing the importance of audio clarity. Once the audio is ready, the user is instructed to name the voice model, and it will be quickly ready for use with text-to-speech functionality.
๐ฅ Creating Lip-sync Videos
This paragraph explains how to create lip-sync videos using the generative audio tool. It requires an image or video of a person with a full face visible within the frame. The user can upload their own media or choose from preset characters. The paragraph outlines the process of adding generated audio from text-to-speech, recorded audio, or uploaded audio, and then selecting a voice to generate the lip-sync effect. It also provides a tip on how to handle videos longer than the audio by using Gen 2 to create a video from an image and then adding lip-sync in the generative audio tool, with a note on avoiding camera motion parameters for a smoother reversing effect.
๐ Conclusion and Additional Resources
The final paragraph wraps up the video with a conclusion, thanking viewers for their time and encouraging them to engage with the community on Discord for more information and experimentation with Runway. It also mentions the availability of a button on the dashboard for finding specific answers to questions. The speaker reiterates the invitation to get started with the work at hand and ends the video with a warm appreciation for the viewers' attention.
