What is a vub?

A "vub" refers to a visual dub or video modification created using assistive AI technology. It is the output you get when you combine Source Media and Driving Data. 

Elements like dialogue, facial expressions, or even whole performances can be altered or substituted while preserving a high degree of realism.

What are the vub quality levels available in DeepEditor and how should I use them?

Please read DeepEditor Vub Quality Levels for full details of each vub quality and how to use it.

How long does each step in the vub creation process take?

• Uploading Source, Driving Data and Training Data (optional) material: On average, it takes less than a minute. The length and size of your files may affect this time. 
• Generate a vub: Generating a vub can take between 1 and 12 hours, depending on the vub quality you selected, the length of the media, and whether you have added training data. If you haven't received a notification e-mail on completion of a vub and things have taken longer than a day, check the queue to see if the vub failed. See Common Issues and Solutions for more information.
• Download/Review your new file: Your vub will reach your downloads folder in less than a minute for review or conform.
• Render (in the Refinement tool): Rendering a change to your vub can vary based on the amount of changes and the length of the clip. On average, rendering will take about 20 minutes.

How long does it take for a vub to be generated?

This depends on a number of factors, such as the resolution and length of your media and whether you included training data. Here are the average times it currently takes to generate a vub:

How do I rename a vub?

To rename a vub, click on the pencil icon next to the vub name, then type the new name.

How do I stop a vub from generating?

Currently, there is no way to stop the process once you've clicked “Generate Vub”.

What happens if I use a different set of training data files when I upgrade my vub?

If the training data used for the upgrade differs from the training data used for the draft, you can expect changes in image quality (typically an improvement) and possibly slight shifts in lip sync. For this reason, it’s important to review the upgraded vub once it’s complete. All overrides and their keyframes will be preserved.

I want to upgrade a draft vub using an older render, not the most recent. How do I do that?

When you use the “Create Upgraded Version” button in DeepEditor, it will always upgrade from the most recent render. If you want to upgrade an older render, follow these steps:

1. Load the desired older render in the Refinement tool using the 'Load' button.
2. Make an arbitrary change in the Refinement tool (e.g. adding a new keyframe with a value of 0).
3. Hit 'Render changes.'
4. This will bump your 'older render' to the top of the list making it the latest.
5. Create your upgraded version.

My render has a glitch at the edge of the face mesh. Is there anything I can do to fix it?

In rare cases, you may notice minor visual artifacts in a vub export, such as subtle edge issues around the face mesh. There are two recommended approaches for addressing this, depending on the severity and nature of the artifact.

Option 1: Adjust within the Refinement Session

For very minor artifacts, it can be worth revisiting the refinement session in DeepEditor.
Introducing a small amount of interpolation can allow a hint of the original plate to blend back into the result, which may help smooth fine edge detail or resolve subtle transitions.

This approach is best suited to light, localized artifacts and can often be addressed directly within the product.

Option 2: Use the VFX Turnover Package

If the artifact persists, or if finer pixel-level control is required, we recommend using the VFX turnover package included with final vub outputs.

This package is designed for 2D compositing workflows, most commonly in Nuke, and allows a visual effects artist to perform targeted beauty work, edge cleanup, or pixel-level refinements. This mirrors standard post-production practices and gives teams full control over final image polish.

While DeepEditor delivers high-quality results, no AI-based solution can be considered absolutely pixel-perfect in every scenario. For this reason, we intentionally provide both in-product refinement tools and a professional VFX handoff, ensuring you always have a path to achieve final-frame quality.

If you believe the artifact is unexpected or persistent, please contact support@flawless.app and our team will be happy to investigate further.

How can I get the best results in DeepEditor?

Ensure your footage meets the following conditions:

• Head rotation: We can see both eyes of the speaking character at all times.
• Head tilt: We can see the entire face. No extreme angles. 
• Jaw in shot: We can see the entire face. No extreme closeups.
• Facial hair: Clean face to short facial hair. No full beards.
• Occlusions: No objects come in front of the lower half of the face.
• Lighting: All facial features are light enough to be distinguishable.
• Distortion: No unusual appearances (e.g. heavy make-up or non-human).
