Add References and Avatars

Give Veo3 AI Agent clear reference material, explain what each file controls, and browse avatars before planning a generation.

Add reference material when the result needs to match a particular product, person, setting, or existing clip. Tell Agent what each reference should control and which details must remain unchanged.

Add material to your message

In the Canvas chat, select + / Add attachment. The menu offers three sources:

SourceWhat to do
Upload from deviceChoose an image, video, or audio file from your device
My CreationsBrowse the available creations and select a reference image
Select AvatarBrowse your avatars or public avatars
Canvas: Choose where to add a reference from
CanvasChoose where to add a reference from

For a product film, start with a clear product photo:

  1. Select Upload from device and choose the photo.
  2. Wait for the upload to finish and check that the attachment appears in the message.
  3. Describe the film and the details the photo should preserve.
  4. Select Send.

You can also drag a supported media file into the chat input area. Follow any file or attachment limit shown in the interface. Paste a written brief directly into the message.

Use the attached bottle photo as the product reference.
Create an 8-second vertical 9:16 product film in a clean pink studio.
Keep the bottle shape, pump, label layout, and label text consistent with the photo.
Use soft lighting and gentle camera motion. No people, music, or added text.
First propose two shots. Do not generate assets yet.

If you start with a homepage example such as Beauty CGI ad, check the draft before sending: the example adds both a prompt and a product image. Replace that image and update the product description when using your own product.

Give every reference a job

When attaching several files, identify them by filename or a clear visual description. Separate the subject you want to preserve from the style you want to borrow.

MaterialExplain its role
Product photoExact product appearance, packaging, proportions, and label
Person or character imageIdentity, clothing, and details that should stay consistent
Setting or style imageLighting, colors, background, or framing to borrow
Existing videoWhich clip to work from and what action or timing to preserve
Audio fileWhether it is intended for the finished soundtrack or as a reference
The bottle photo defines the product. Keep its packaging unchanged.
The pink studio image is a lighting and background reference only.
Do not copy the product shown in that studio image.
Plan a close-up followed by a wider hero shot using the same bottle.

Uploading a file gives Agent material to work with. Before generation, check that the planned shot uses the intended reference. Different generation models accept different combinations of images, video, and audio; ask Agent to explain the proposed setup if the role is unclear.

Check the displayed quote before selecting Confirm, Confirm all, Generate, or Save as variant. These controls can submit generation directly. On a generated image, Save as variant creates and runs a new paid version without a separate confirmation dialog.

Refer to a specific Canvas node

Use a node mention when your request concerns a particular reference or shot already on the Canvas.

  1. Type @ in the chat input to open the Nodes menu.
  2. Select the reference or shot you mean, such as Shot 2.
  3. Check that a chip with the node's title appears in your message.
  4. Add the instruction beside that chip, then select Send.
Chat: Type @ and select the node your instruction refers to
ChatType @ and select the node your instruction refers to

For example, select the Shot 2 node, then write:

Reduce the camera motion in this shot to a slow push-in.
Keep its product reference, lighting, and duration unchanged.
Keep Shot 1 as it is. Show the revised setup before generation.

The chip identifies the node; your words specify what should change.

Browse an avatar

Open Add attachment → Select Avatar. The picker includes My Avatars, Create Avatar, and Public Avatars.

  1. Open an available avatar to inspect its details.
  2. If a voice preview is shown, play it before choosing.
  3. Select Use this avatar.
  4. Describe the avatar's role, appearance, action, and any spoken words in the chat.
Avatar picker: Inspect the character and available voice preview
Avatar pickerInspect the character and available voice preview

For a speaking scene, write the dialogue exactly and state its language. Ask Agent to propose the workflow before generation so you can review how the character, speech, and video will be produced.

Plan a short presenter scene using this avatar.
Use a simple studio and a medium shot.
The presenter says, in English: "Meet your new morning ritual."
Keep the delivery calm and conversational. No subtitles or background music.
Show me the plan and generation settings before creating anything.

Review the reference in the result

Check product shape, visible text, facial details, clothing, and framing. References guide generation; review the actual result before using it in a final film.

If something drifts, identify one concrete mismatch and the reference it should follow:

The bottle cap in the second shot is too tall.
Use the original attached product photo to correct the cap proportions.
Keep the first shot, lighting, framing, and camera movement unchanged.
Show the revised generation setup before running it.
