Canvas Editor
Advanced in-app image editing with layers, masks, annotations, and composition tools. Create complex edits without leaving Chat Video Pro.
Canvas Editor is the controlled image-editing workspace inside Chat Video Pro. Use it when you need to show the app where something should happen, not just describe the change in a prompt.
If Image-to-Image is prompt-guided revision, Canvas Editor is visual-guided revision. You still write a prompt, but you also give the model masks, boxes, arrows, text, or added images so it understands the exact area, placement, or composition you want.
Use Canvas when location matters. If you have tried a normal Image-to-Image prompt twice and the model keeps changing the wrong part of the image, move into Canvas Editor.
What This Tool Is For
Use Canvas Editor when you want to:
Change one specific region of an image.
Remove or replace a local object.
Add a new element in a specific position.
Point to what should move, change, or stay.
Compose multiple images together.
Place text, labels, badges, or layout notes.
Give the model visual markup instead of relying only on language.
Use a different workflow when:
Make a global style or mood change
Image-to-Image
Generate a new image from scratch
Text-to-Image
Remove the entire background from an image
Background Removal
Build a cinematic still for video
Studio Cinematic Lab
Upscale a finished image

Canvas Editor vs. Image-to-Image
Both edit existing images. The difference is how much control you need.
The whole image needs a style, mood, color, or background change.
The edit depends on a specific area.
The edit is easy to describe in one prompt.
You need to draw, mask, or point.
Speed matters more than exact placement.
Exact placement matters more than speed.
You want broad creative variations.
You want a directed revision.
Example:
Image-to-Image prompt:
Make this scene feel like golden hour.Canvas Editor prompt:
Remove this sign and rebuild the wall behind it.with the sign brushed or boxed.

How Canvas Edits Work
Canvas Editor uses your visual markup to decide what kind of edit you are asking for.
Brush or draw over an area
This is the region to change, remove, or rebuild.
Draw a box or ellipse
This is the target area or object.
Add an arrow
This is the direction, location, or object being referenced.
Add text
This text or label should be part of the edit or layout.
Add another image
Use this as a composited element or visual reference.
You do not need to choose a technical pipeline. The editor reads your markup and sends the right context with your prompt.

Common Workflows
Remove A Specific Object
Open Canvas Editor.
Brush or box the object.
Prompt:
Remove this object and rebuild the background naturally.Apply the edit.
Review the result.
Best for small distractions, signs, logos, props, or background objects. For full transparent cutouts, use Background Removal.
Change One Part Of An Image
Select the area you want to change.
Prompt the specific change.
Add preservation language for everything else.
Example:
Add An Object In A Specific Spot
Draw a box where the object should go.
Prompt the object, scale, and style.
Include what should stay unchanged.
Example:
Compose With Another Image
Open Canvas Editor.
Click Add Image.
Upload the product, logo, subject, prop, or reference asset.
Position it where it should appear.
Prompt how it should blend into the scene.
Example:
Build A Thumbnail Layout
Open a strong image or thumbnail background.
Add text or arrows to block the layout.
Prompt the intended design.
Keep text short and clear.
Canvas is useful for thumbnail planning because placement matters. For a more thumbnail-specific workflow, use Thumbnail Mode.
Prompting In Canvas
Canvas prompts should refer to your visual markup.
Good phrases:
In the selected area...Remove the brushed object...Replace the boxed region with...Place the added image naturally into the scene...Follow the arrow and move the object slightly to the right...Keep everything outside the selected area unchanged...
Useful structure:
The most common mistake is writing a broad prompt after making a precise selection. If you selected one area, keep the prompt local.
Choosing A Model
Canvas Editor works with the current image edit models in Chat Video Pro. Choose based on the hardest part of the edit.
Text, labels, layout, or complex instruction following
GPT Image 2 or Ideogram V4 Fast
Strong general image editing
Nano Banana 2
Polished realism or premium finish
Flux 2 Max
Region-precise edits or poster/UI layouts
Seedream 5.0 Pro
Fast creative variations
Grok or Ideogram V4 Fast
If one model keeps misunderstanding the markup, try GPT Image 2 for complex composition or Nano Banana 2 for a strong general pass.
Best Practices
Select Only What Needs To Change
Do not brush half the image if only one object needs editing. Smaller, cleaner selections usually produce cleaner results.
Say What Should Stay The Same
Canvas tells the model where to look, but the prompt should still protect important details: subject identity, pose, product shape, text, lighting, framing, and background.
Use One Clear Edit Per Pass
For complex edits, work in stages:
Remove or replace the object.
Adjust lighting or style.
Add text or layout details.
Upscale only after the image is approved.
Use The Right Markup
Use brush for organic shapes, boxes for hard-edged areas, arrows for direction, and added images for composition. The cleaner your visual instruction, the less the model has to guess.
Keep Source Quality High
Canvas can guide the edit, but it cannot fully fix a weak source image. Use clear images with enough resolution for the model to understand the subject.
Troubleshooting
The Wrong Area Changed
Make the selection smaller and add location language in the prompt, such as only the selected sign, the object inside the box, or the brushed area in the background.
The Edit Ignored My Markup
Use a more direct prompt that refers to the markup: Use the selected area as the only edit region. If that fails, try a different model or simplify the selection.
The Image Changed Too Much
Add preservation language: Keep everything outside the selected area unchanged. Also avoid asking for broad style changes in the same pass as a local edit.
Added Images Do Not Blend Naturally
Prompt for integration: match lighting, perspective, shadows, color temperature, and depth of field. If the added asset has a transparent background, it often works better as a clean product, logo, sticker, or prop.
Text Is Not Perfect
AI-generated text can still drift. Use GPT Image 2 for text-heavy edits, keep wording short, and add final production text manually if exact typography matters.
