# Video Upscaling

Upscale is the Studio workflow for increasing video resolution after a clip is generated, imported, cleaned up, or edited. Use it when the idea is working, but the final video needs more pixels, sharper detail, or a better delivery format.

Chat Video Pro supports multiple AI video upscalers, including **Topaz**, **Flash VSR 2**, and **Bria Video Increase Resolution**. Studio opens the same professional upscaling controls from a cleaner starting point, so you can load footage and go straight to resolution work.

### What This Tool Is For

Upscale is for **making a finished or near-finished video larger and cleaner**. It is usually the last step, not the first.

Use it for:

* Turning a generated 720p or 1080p clip into a higher-resolution delivery asset.
* Preparing AI results for client review, YouTube, social platforms, or a Premiere timeline.
* Improving apparent sharpness after Add Effects, Reshoot, Erase Objects, or Relight Scene.
* Matching lower-resolution inserts to a higher-resolution edit.
* Creating a cleaner master before compression.
* Testing whether older or lower-resolution footage can hold up in a modern project.

Upscaling is not magic restoration. It can add detail, sharpen edges, and improve perceived resolution, but it works best when the source clip is already stable, clean, and worth finishing.

### When To Use It

Use Upscale when the clip content is already approved and the main issue is resolution or delivery quality.

<table><thead><tr><th width="325">Goal</th><th>Why Upscale helps</th></tr></thead><tbody><tr><td>Finish an AI-generated clip</td><td>Raises the output resolution after generation.</td></tr><tr><td>Improve a post-production result</td><td>Makes cleanup or VFX results feel more finished.</td></tr><tr><td>Match a 4K timeline</td><td>Helps lower-resolution shots sit better beside 4K footage.</td></tr><tr><td>Prepare for client review</td><td>Gives the result a sharper, more polished presentation.</td></tr><tr><td>Create a higher-quality master</td><td>Lets you upscale before final export/compression.</td></tr></tbody></table>

Choose another Studio workflow first when:

<table><thead><tr><th width="415">Goal</th><th>Better workflow</th></tr></thead><tbody><tr><td>Remove an unwanted object</td><td>Erase Objects</td></tr><tr><td>Keep a subject and remove the background</td><td>Rotoscope</td></tr><tr><td>Change a short section of the clip</td><td>Reshoot</td></tr><tr><td>Add atmosphere, VFX, or style</td><td>Add Effects</td></tr><tr><td>Change lighting or mood</td><td>Relight Scene</td></tr></tbody></table>

For most workflows, upscale after the creative edit is finished. If you upscale first, then edit, you may spend more time processing larger files and still need to upscale again at the end.

### Studio Path

The fastest route is through Studio.

1. Open **Studio**.
2. Choose **Upscale** from the Post-Production department.
3. Load a video from upload, Recents, or your Premiere timeline.
4. Choose the upscale model.
5. Choose a scale factor.
6. Pick codec or quality options when the selected model exposes them.
7. Review the output resolution preview.
8. Click **Generate Upscale**.
9. Compare before/after and click **Done** when you want to send it back to your chat/library.

Studio opens the video editor directly in Upscale mode. The default model is Topaz, and Studio disables models or scale factors when the requested output would exceed the model's limits.

### Classic/Editor Path

You can also upscale from the classic video editor path:

1. Import or generate a video.
2. Click **Edit** on the video thumbnail.
3. Choose **Upscale** from the model selector.
4. Configure model, scale, and output settings.
5. Generate and review.

The older **Transform** button path can also open upscaling controls from a video thumbnail. Use whichever path is closest to the asset you are already working with. For new finishing work, Studio is the cleanest starting point.

### Controls And Constraints

<table><thead><tr><th width="235">Control</th><th>What it does</th></tr></thead><tbody><tr><td>Output Resolution</td><td>Shows the expected width and height before you generate.</td></tr><tr><td>Upscale Model</td><td>Chooses Topaz, Flash VSR 2, or Bria.</td></tr><tr><td>Scale Factor</td><td>Multiplies the source resolution by the selected factor.</td></tr><tr><td>Output Codec</td><td>Topaz exposes H.264 and H.265 options.</td></tr><tr><td>Output Quality</td><td>Flash VSR 2 exposes Low, Medium, High, and Maximum quality.</td></tr><tr><td>Generate Upscale</td><td>Starts the upscaling job.</td></tr><tr><td>Cancel</td><td>Stops an active upscale job when possible.</td></tr></tbody></table>

Current constraints:

<table><thead><tr><th width="253">Constraint</th><th>Detail</th></tr></thead><tbody><tr><td>Source type</td><td>Video only.</td></tr><tr><td>Default model</td><td>Topaz.</td></tr><tr><td>Common scale factors</td><td>1.5x, 2x, 3x, and 4x, depending on model and source resolution.</td></tr><tr><td>Topaz output limit</td><td>Up to 4K output.</td></tr><tr><td>Flash VSR 2 output limit</td><td>Up to 4K output.</td></tr><tr><td>Bria output limit</td><td>Up to 8K output, with a 30-second video limit.</td></tr><tr><td>Reference images</td><td>Not used. Upscale works from the source video.</td></tr></tbody></table>

If a model or scale factor is disabled, it usually means the output would exceed the model's maximum resolution or duration limit.

### Choosing A Model

#### Topaz

Topaz is the best default for most users.

Use Topaz when:

* You want reliable, professional upscaling.
* You need a straightforward 1.5x, 2x, 3x, or 4x upscale.
* You are preparing AI-generated video for review or delivery.
* You want H.264 for compatibility or H.265 for smaller files.

Topaz is usually the safest first pass because it balances quality, predictability, and simple controls.

#### Flash VSR 2

Flash VSR 2 is useful when you want more control over the upscale quality.

Use Flash VSR 2 when:

* You want to compare quality levels.
* You are working with footage that needs a more controlled enhancement.
* You want a 4K-capped model with a quality setting.
* You are testing which upscaler treats your footage best.

In the current Studio/video editor flow, Flash VSR 2 is kept compatible with the CEP workflow by outputting an MP4-friendly result.

#### Bria

Bria is the option to consider when you need the highest output ceiling.

Use Bria when:

* You need up to 8K output.
* Your clip is short enough for Bria's 30-second limit.
* You want to test a quality-focused upscale against Topaz.
* Your source is already clean enough to justify a large output.

Bria is not the best starting point for long clips because of the duration limit. For longer videos, use Topaz or Flash VSR 2 when available.

***

### Codec And Quality Choices

#### H.264

Use H.264 when you want the safest, most compatible output.

Best for:

* Review links.
* Social delivery.
* General Premiere workflows.
* Smaller, easier-to-share files.

#### H.265

Use H.265 when you want better compression and your editing/delivery environment supports it.

Best for:

* Smaller files at higher resolution.
* Modern devices and platforms.
* Storage-conscious delivery.

#### Flash VSR 2 Quality

Flash VSR 2 exposes quality levels:

<table><thead><tr><th width="289">Quality</th><th>Best for</th></tr></thead><tbody><tr><td>Low</td><td>Fast tests.</td></tr><tr><td>Medium</td><td>Balanced previews.</td></tr><tr><td>High</td><td>Default high-quality output.</td></tr><tr><td>Maximum</td><td>Slowest pass when quality matters most.</td></tr></tbody></table>

Use **High** first. Move to **Maximum** only when the source is worth the extra processing time.

### Best Practices

#### Upscale Last

Do creative work first, then upscale. This keeps iteration faster and avoids processing large intermediate files repeatedly.

Good order:

1. Generate, edit, clean up, or relight the clip.
2. Review the creative result.
3. Upscale the approved version.
4. Export or continue finishing in Premiere.

#### Start With 2x

2x is the most useful first test. It gives a clear quality bump without pushing the model as hard as 3x or 4x.

#### Watch For Sharpened Artifacts

Upscaling can make compression blocks, noise, flicker, motion blur, and AI artifacts more visible. Review faces, text, hands, edges, and high-motion areas after the upscale.

#### Match The Destination

Upscale for the project you are actually delivering:

* 1080p social ad: 1.5x or 2x may be enough.
* 4K timeline: 2x from 1080p is usually the practical target.
* Large display or special delivery: test Bria or a larger scale if the source supports it.

#### Do Not Use Upscale To Fix A Bad Generation

If the motion is wrong, the subject is inconsistent, or the VFX pass failed, upscale will only make the problem clearer. Fix the creative issue first, then upscale.

***

### Troubleshooting

#### A model is disabled

The source video may be too long or the requested output may exceed the model's limits. Bria is limited to 30 seconds, and Topaz/Flash VSR 2 are capped at 4K output.

#### A scale factor is disabled

The output resolution would be too large. Choose a lower scale factor or a different model.

#### The upscale is slow

Use a lower scale factor, a shorter clip, or a faster quality setting. Higher resolution outputs take longer to process.

#### The result looks sharper but worse

The source may contain compression, noise, flicker, or AI artifacts. Try a lower scale factor, use a cleaner source, or fix the creative issue before upscaling.

#### The file is too large

Use H.264 for compatibility or H.265 for smaller files when your workflow supports it. Avoid unnecessary 4x upscales when the delivery target does not need them.

#### The output does not match expectations

Try another model. Topaz, Flash VSR 2, and Bria can treat detail, edges, and motion differently. A one-model test is not always enough for important delivery work.
