Topaz Video AI is a professional video enhancement and restoration software based on artificial intelligence technology, designed specifically for the macOS system. Through advanced deep learning models, it can perform complex processing on videos such as super-resolution upscaling, deinterlacing, denoising, deblurring, stabilization, and frame rate improvement, aiming to restore clear, stable, and high-resolution footage from low-quality source material.

I. Detailed Explanation of the Core Interface and Workspace

The main interface of the software adopts a clean and intuitive single-window design, primarily divided into four functional areas.

Top Menu Bar and Toolbar: Includes standard file operations (New, Open, Save), processing queue controls (Start, Pause), preview mode switching, and the global settings entry point.
Left Media Library and Preview Panel:
- Media Library: Displays all video clips of the imported project, supporting multi-selection and batch operations.
- Source Preview Window: Displays the real-time frame of the original video, with playback controls and a timeline below.
Central Processing Parameters Panel: This is the core control area of the software. All AI models and adjustment parameters are set here.
- “Enhance” Module: Provides model selections such as Proteus (general enhancement), Gaia (high-quality denoising and restoration), Apollo (low-light video enhancement), etc.
- “Scale” module: Set the output resolution; models such as Artemis (used for high-quality upscaling and deblurring).
- “Stabilize” and “Frame Interpolation” modules: Used respectively to fix shaky footage and generate smooth slow-motion effects.
- Each module has fine-tuning sliders for strength, noise reduction, detail recovery, and more.
Right-side output preview and queue panel:
- Output preview window: Displays the picture in real time with all effects applied, and supports side-by-side comparison with the source (Split View) or split-screen comparison.
- Processing queue: Shows the list of tasks waiting to be processed and currently being processed, and lets you manage task priority.

II. Complete Workflow: From Import to Export

Step 1: Create/Open a Project and Import Media

Method: After launching the software, you can import videos in any of the following ways:

Click the “+” button in the toolbar or use the shortcut Cmd + O.
Drag video files directly from Finder into the “Media Library” area on the left.

After importing, video clips will be displayed as thumbnails in the Media Library.

Step 2: Add Videos to the Processing Queue and Configure Parameters

Method:

In the media library, double-click the target video or drag it into the central parameter area to activate it as the current processing target.
In the central panel, configure each module in sequence:
- Select an appropriate AI model from the “Enhance” drop-down menu. For example, for old videos with noise, you can first try Gaia HQ.
- In “Scale”, select “Manual” and enter the target resolution (e.g., 3840×2160), or select a preset ratio (e.g., 200%). The model usually automatically matches Artemis.
- Adjust the sliders below each model (e.g., “Enhance”, “Denoise”, “Sharpen”); the output preview on the right will update in real time.
(Optional) Enable the “Stabilize” or “Frame Interpolation” features and fine-tune the parameters.

Step 3: Preview and Compare Results

Method:

Use the play button below the output preview window or press the spacebar to play/pause the preview.
Click the “Split” button above the preview window to switch between side-by-side, split-screen, or slider comparison modes for a visual before-and-after comparison.
Drag the red marker line on the timeline to check the effect at different points in time.

Step 4: Add to Processing Queue and Set Output Parameters

Method:

After confirming the result, click the “Add to Queue” button in the lower right corner of the central panel.
In the queue panel on the right, click the “Output File” link for that task, and the output settings window will pop up.
Settings:
- Output Format: Commonly MP4 (H.264) or MOV (ProRes to maintain the highest quality).
- Codec, Bitrate, Frame Rate: Adjust according to your needs.
- Output Folder: Specify the save location.
Click “Save” to confirm the output settings.

Step 5: Batch Processing and Final Export

Method:

In the queue panel on the right, check all pending tasks and their output settings.
Click the “Start Processing” button at the top of the queue panel (a triangle icon) or use the shortcut Cmd + P.
The software will begin rendering. You can view the progress and estimated remaining time for each task in the queue panel. The rendering process will heavily use GPU and CPU resources.
After processing is complete, the files will be automatically saved to the preset output folder. The task status in the queue will show as “Completed”.

III. Advanced Tips for Common Features

Model stacking and order: Models can be combined when handling complex problems. Recommended order: first perform denoising/degraining (e.g., Gaia) -> then perform enhancement and upscaling (e.g., Proteus/Artemis) -> finally apply stabilization or frame interpolation. Avoid enabling multiple conflicting enhancement models at the same time.
Use the preview area for fine-tuning adjustments: Use Cmd + mouse scroll wheel to zoom in on the image in the preview window, inspect detail restoration effects (such as faces and text), and fine-tune sliders such as “Restore Original Detail” accordingly.
Selective processing: For long videos, if only some segments need repair, you can first use Cmd + E to split the video into multiple segments, then apply high-intensity processing only to the segments that need it, to save time.
Preserve original data: In the output settings, if storage space allows and for later production, it is recommended to choose lossless or high-quality intermediate codecs such as ProRes 422 or ProRes 4444 to avoid multiple lossy compressions.

IV. Common Problems and Solutions

Problem Symptom	Possible Cause	Solution
Processing speed is extremely slow	1. A computationally intensive model combination was selected (such as Artemis + high upscaling). 2. Insufficient system memory (RAM). 3. GPU acceleration is not enabled.	1. Try a single model, or reduce the upscaling factor. 2. Close other large applications and ensure at least 16GB of available memory. 3. In “Preferences” > “Processing”, confirm that “Use GPU” is checked.
Flickering or ghosting appears in the output video	1. The AI model strength setting is too high. 2. The source video itself has severe compression artifacts or dropped frames.	1. Lower the “Enhance” or “Sharpen” slider values and try different AI models. 2. Try using the “Deinterlace” or “Temporal Denoise” feature first for preprocessing.
The software cannot import certain video files	The video encoding format is too unusual or the container is corrupted.	Use a third-party transcoding tool (such as HandBrake) to first convert the video to a standard format (such as H.264 MP4), then import it for processing.
Preview stutters or is not smooth	Real-time preview requires a large amount of computation, especially after multiple effects have been applied.	1. Lower the preview resolution below the preview window (for example, set it to 1/2). 2. Temporarily disable “Real-time Preview” and check static frame effects only by dragging the timeline.
Exported file size is abnormally large	The output format selected is a lossless codec (such as ProRes) or the bitrate is set too high.	Adjust according to use: for online sharing, choose H.264 with a bitrate of 8-20 Mbps; for archiving or later production, choose ProRes 422.
