Editing Videos — References (v1.11)

In the References section, click the Source Video slot to load the original video (.mp4 or .mov), or drag it directly from the History panel on the left.


Hover over the video thumbnail to view an enlarged preview.

After the original video is loaded in, click a Reference slot next to it to add inputs that guide video editing and improve consistency in actors or environments. Supported reference types include AI Actors, images, videos, and audio.


Before adding references, check the requirements for each media type, including format, aspect ratio, resolution, file size, and duration, as shown below. If a reference does not meet the requirements, a compatibility warning dialog will identify the issue preventing the upload.

AI Actors and images share a combined limit. For example, you can use 5 AI Actors and 4 images, or 2 AI Actors and 7 images. If the original video shows a model walking on a runway, you can create a custom AI Actor based on the model, add reference images of luxury earrings and a bracelet for the model to showcase, and preserve the original environment, background people, and music.

• AI Actor

  After creating custom AI Actors, you can apply them from the AI Actor Library to maintain consistent character appearances in generated videos. Click the Reference slot and select AI Actor. Choose one or more custom actors from the AI Actor Library, then click Apply AI Actors.
  
• Image

  Click the Reference slot and select Image to upload an image to add to the video, such as an accessory. Alternatively, drag an image from the History panel on the right or Windows File Explorer.
  
• Video

  Select Video and upload a video reference to replace the original video's character motion, voice, visual style, composition, or background music.
• Audio

  Select Audio and upload audio to add or replace the original video's character dialogue or background music.

After adding references, use the Reference tools to filter reference types and check the current input counts and media durations.

1. Reference Filter: Filters references by All, Image, Video, or Audio, and displays the input count for each type.
2. Video Duration: Displays the current video input duration and the maximum duration supported by the selected AI model.
3. Audio Duration: Displays the current audio input duration and the maximum duration supported by the selected AI model.
4. Reset All:Removes all reference inputs.

Hover over a Reference thumbnail to preview the actor, image, video, or audio.

Each reference is represented by a label tag in the Prompt field for quick editing and reference assignment. Click the Reset Prompt button to clear the prompt field and start over if needed.

• Drag the tag to reposition it within the prompt.
• Click Copy on a reference thumbnail to insert its tag into the prompt. Alternatively, click Add Reference @ or type @ to select a reference tag from the context menu. Use the Image, Video, Audio, and AI Actor filters to show only references of the selected media type.
  

Enter a prompt describing how each reference should be used. You can enter a custom prompt and use a Large Language Model (LLM), such as ChatGPT, to refine it for better video generation with the selected AI model, or apply preset Camera Techniques to animate the camera.

Assign AI Actor: Insert an AI Actor tag, such as [Amani Diallo], into the prompt to maintain consistent character appearance. Assign Images: Insert image tags, such as [Image 1] and [Image 2], into the prompt to add accessories to specific parts of the character's body. Assign Video: Insert the [Source Video] tag into the prompt to preserve or modify specific elements and visual styles from the reference video. For example, "When the model Amani Diallo wears the earrings from Image 1 and the luxury bracelet from Image 2, she walks toward the foreground and stops. She then strikes a sexy pose and raises her right wrist toward her opposite shoulder to show off the bracelet. Finally, she walks back. Maintain the original model, runway, camera angles, lighting, rendering style, and music from Source Video. As the model walks down the runway, have the background people lower their mobile phones and watch the model walk by.".

Drag the bottom-right corner to expand the text field for longer descriptions.

Set the video output options in the Render section, including resolution and audio settings.

• Ratio: Automatically maintains the original aspect ratio of the source video.
• Resolution: Select the desired video resolution from the options supported by the selected AI model. The output is generated at the selected resolution while automatically maintaining the source video's aspect ratio.
  
• Seconds: Under Edit Video, the video duration is fixed to the duration of the original video.
• Generate with Audio: Choose whether to include audio generated from the prompt in the video. Enable this option before generation to add background audio. Additional charges may apply.
