MagicEdit is a video editing method published by ByteDance, which is a multimodal framework focused on multimodal input generation. It can transform different input modalities such as text, video, and audio into action signals, thereby generating and animating a virtual character.

Specifically, MagicAvatar can create virtual characters through simple text prompts, and can also generate virtual characters that follow given actions based on the source video generation. In addition, MagicAvatar can also animate virtual characters of specific subjects. It will also launch a feature in the future that creates virtual characters based on audio input.

Different from the way of directly generating video, MagicAvatar explicitly divides video generation into two stages:

(1) Multimodal information to motion

(2) Motion to video.

The first stage converts multimodal input into motion information (e.g., human body pose, depth, density), while the second stage generates video guided by these motion signals.

MagicAvatar generates video by simply providing a few images of the target character. We demonstrate the flexibility of MagicAvatar through various applications, including text-guided and video-guided avatar generation, as well as multimodal avatar animation.

MagicEdit also supports a variety of editing applications, including video stylization, local editing, video mixing (Video-MagicMix, etc.). Video stylization means being able to transform the source video into a specific style, creating new scenes with different subjects and backgrounds, such as realistic, cartoon, etc.

MagicEdit provides users with an excellent text-to-video editing tool. Users can easily change the style and scene of the video, or even replace objects in the video or add elements, while keeping the original video's actions and appearance unchanged, by simply using natural language prompts. In addition, MagicEdit also provides a video mixing feature that allows users to create entirely new concepts.

In addition, MagicAvatar also supports users to upload images of target characters to generate animations for specific characters, achieving personalized needs.

ByteDance's AI video projects: MagicAvatar and MagicEdit, demonstrate amazing potential in the fields of multimodal input and video editing.
