Video Canvas Editor
The Video Canvas Editor is the central hub for all video editing operations in Chat Video Pro. Access all the editing tools from one unified interface.
The Video Canvas Editor is the classic full-screen editor for working from an existing video result. Use it when you already have a generated or imported clip in Chat Video Pro and want to open a familiar editor surface for rotoscoping, object removal, effects, reshooting, or upscaling.
Use the Video Canvas Editor when you are already looking at the clip you want to edit. Use [Studio](../studio/README.md) when you want to start from a guided workflow card like Rotoscope, Erase Objects, Add Effects, Reshoot, Upscale, or Relight Scene.
What This Page Is For
The Video Canvas Editor is not a separate creative category. It is an entry point.
Use it when:
A video result is already in chat.
You imported a clip and want to work from its thumbnail.
You want to test a quick edit without opening Studio first.
You want to compare before/after results in the same editor.
You are comfortable choosing the editing mode manually.
Use Studio instead when:
You know the job before choosing a clip.
You want the workflow to open with the correct model and controls already selected.
You are starting from Premiere timeline media.
You want the newer guided Studio path for production or post-production tasks.
How To Open It
Generate or import a video in Chat Video Pro.
Click Edit on the video thumbnail.
The Video Canvas Editor opens full screen.
Choose the editing mode from the selector.
Configure the mode-specific controls.
Process the edit, review the result, then click Done when you want to send it back to chat.
If you are starting from a clip in Premiere, Studio is often faster because the workflow asset loader can pull from your timeline and open the correct tool directly.
Video Canvas Editor vs. Studio
Both paths can reach many of the same underlying AI tools. The difference is how you start.
Video Canvas Editor
You already have a video in chat and want to edit that exact result.
Studio
You know the task first and want a guided workflow with the right loader, model, and controls.
Examples:
Open a generated clip and quickly upscale it
Video Canvas Editor
Pull a selected Premiere timeline clip into Upscale
Studio Upscale
Try an effect on the video result you just made
Video Canvas Editor
Start a clean Add Effects workflow from a source clip
Studio Add Effects
Rotoscope a clip already visible in chat
Video Canvas Editor
Start a guided subject-isolation workflow
Studio Rotoscope
The practical rule: Video Canvas Editor is clip-first. Studio is task-first.
Editing Modes
The available modes can vary by release, clip type, and model availability, but the classic editor is mainly used for these video tools:
Rotoscope
Selecting and isolating a subject from the background.
Erase Objects
Removing unwanted people, objects, gear, text, or distractions from short clips.
Add Effects
Adding rain, fire, fog, atmosphere, style, or visual transformations.
Reshoot
Regenerating a selected segment of video, audio, or both.
Upscale
Increasing resolution and improving the finish after the edit is approved.
Interface Overview
Video Player
Use the player to review the source clip, scrub the timeline, and inspect the result after processing.
Model Selector
The selector switches between editing modes. When you change modes, the right-side controls change with it.
Mode Controls
Each mode has its own controls:
Rotoscope uses text, box, or point selection.
Erase Objects uses text or point selection to mark what should disappear or be protected.
Add Effects uses a prompt and optional reference images.
Reshoot uses a timeline segment, prompt, and retake mode.
Upscale uses a model, scale factor, codec, and quality settings.
Before/After Review
After a result is generated, use the before/after view to check whether the edit improved the clip. If the edit missed the target, revise the prompt, selection, segment, or mode before sending it back to chat.
Common Workflows
Quick Follow-Up After Generation
Generate a video.
Click Edit on the result.
Choose the tool that matches the problem.
Run the edit.
Compare before/after.
Click Done when the result is worth keeping.
This is the best use of the Video Canvas Editor: one more pass on a clip that is already in front of you.
Rotoscope A Clip From Chat
Click Edit on the video.
Choose the Rotoscope/SAM 3 mode.
Select the subject with text, box, or point controls.
Track the frame first if available.
Track the full video.
Remove the background and send the result back.
For the full workflow, use Rotoscope.
Add An Effect To An Existing Result
Click Edit on the video.
Choose Add Effects/Kling VFX.
Write the effect prompt.
Optional: add reference images.
Generate and compare the result.
Good prompts describe what changes and what should remain stable. For example: Add heavy rain and wet street reflections while keeping the same camera move, subject, and composition.
For deeper effect prompting, use Add Effects.
Reshoot One Moment
Click Edit on the video.
Choose Reshoot/LTX Retake.
Select the segment you want to change.
Describe the replacement action, visual, audio, or both.
Generate and compare.
For best results, keep the requested change local and specific. Use Reshoot when you need the complete guided explanation.
Upscale A Final Clip
Click Edit on the video.
Choose Upscale.
Select the upscaler and scale factor.
Choose codec and quality settings if available.
Generate the upscaled result.
Do this after the creative edit is approved. Upscaling drafts wastes time and credits.
Best Practices
Choose The Tool From The Problem
Do not pick a model first. Ask what is wrong with the clip:
The background needs to become transparent
Rotoscope
Something should disappear
Erase Objects
The whole shot needs new atmosphere or effects
Add Effects
One moment needs a different action or audio
Reshoot
The final result needs more resolution
Upscale
Keep Source Clips Short
Video editing models work best on focused clips. Trim around the moment you want to change instead of sending a long sequence with several unrelated actions.
Preview Before Processing When Possible
For selection-based tools, test the first frame or selection before processing the whole clip. A clean selection saves more time than guessing.
Upscale Last
Finish creative changes first, then upscale the version you actually want to keep.
Troubleshooting
The Edit Button Is Missing
Make sure the item is a video result or imported video. Image results use image workflows instead of the Video Canvas Editor.
The Wrong Modes Are Showing
The available modes depend on the source media, model availability, and current app version. If you know the exact workflow you want, open it from Studio instead.
The Result Does Not Match The Prompt
Make the instruction more specific. Describe the subject, what should change, what should stay the same, and the intended style or mood. For Reshoot, make sure the selected segment matches the moment described in the prompt.
The Tool Fails On A Long Clip
Try a shorter clip or smaller segment. Some models have duration, resolution, or codec constraints. Studio workflow pages list the important limits for each tool.
I Am Not Sure Whether To Use This Or Studio
Use the Video Canvas Editor when the clip is already in chat. Use Studio when the task comes first.
