|
| Web Search Results | | To denoise a rendered image sequence in Blender 4.5, you can utilize the Denoise node within the Compositor. Here's a step-by-step guide:<br/><br/>1. **Open a New Blender Project**: Launch Blender and create a new project.<br/><br/>2. **Access the Compositor**: Navigate to the **Compositing** workspace by clicking on the **Compositing** tab at the top of the Blender interface.<br/><br/>3. **Enable Nodes**: In the Compositor, check the **Use Nodes** box to activate node-based compositing.<br/><br/>4. **Remove Default Nodes**: By default, Blender adds a **Render Layers** node. Since you're working with an existing image sequence, delete this node by selecting it and pressing **X**.<br/><br/>5. **Add an Image Sequence Node**:<br/> - Press **Shift + A** to open the Add menu.<br/> - Navigate to **Input** > **Image** to add an Image node.<br/> - In the Image node properties, click **Open** and select the first image of your sequence.<br/> - Enable the **Sequence** checkbox.<br/> - Set the **Frames** value to the total number of images in your sequence.<br/> - Adjust the **Start Frame** if your sequence doesn't begin at frame 1.<br/><br/>6. **Add a Denoise Node**:<br/> - Press **Shift + A** and go to **Filter** > **Denoise** to add a Denoise node.<br/> - Connect the **Image** output of the Image node to the **Image** input of the Denoise node.<br/><br/>7. **Connect to Composite Output**:<br/> - Ensure there's a **Composite** node in your setup. If not, add one by pressing **Shift + A** and selecting **Output** > **Composite**.<br/> - Connect the **Image** output of the Denoise node to the **Image** input of the Composite node.<br/><br/>8. **Set Output Properties**:<br/> - In the **Output Properties** panel (printer icon), specify the output folder and file format for the denoised sequence.<br/> - Ensure the **Frame Start** and **End** match your image sequence.<br/><br/>9. **Render the Denoised Sequence**:<br/> - Go to the **Render** menu and select **Render Animation**.<br/> - Blender will process each frame through the Compositor, applying the denoising effect, and save the denoised images to your specified output folder.<br/><br/>This method allows you to denoise an existing image sequence without re-rendering the original scene. However, it's important to note that denoising in post-processing may not achieve the same quality as denoising during the initial render, especially if the original render lacks necessary passes like Denoising Normal and Denoising Albedo. For optimal results, consider enabling denoising data passes during rendering. ([docs.blender.org](https://docs.blender.org/manual/en/latest/compositing/types/filter/denoise.html?utm_source=openai))<br/><br/>Additionally, Blender 4.5 introduces GPU support for the Open Image Denoise-based Denoise node, potentially improving performance during the denoising process.

How to denoise an image sequence in Blender 4.5:
|
|
|
|
- Set the Output Properties:
|
|
1. Output Properties (printer) → choose a folder and format (PNG/EXR).
|
|
2. Set Frame Start/End to match your sequence range.
|
|
|
|
- In Compositor:
|
|
1. Enable Use Nodes and remove the default Render Layers node.
|
|
2. Add Input > Image:
|
|
- Open the first frame.
|
|
- Enable Sequence.
|
|
- Set Frames to the total count.
|
|
- Adjust Start Frame if not frame 1.
|
|
3. Add Filter > Denoise: image → denoise.
|
|
4. Connect denoise image → Composite input.
|
|
|
|
- For better results (if available):
|
|
- If the sequence includes passes, feed Albedo and Normal to the Denoise node.
|
|
- If not, use Denoise with image only; quality may be lower.
|
|
|
|
- Render: Render > Render Animation. Blender will render the frames with denoising applied.
|
|
|
|
Note: The Denoise node supports GPU in Blender 4.5 for faster processing.

*Called tool*: blender - get_viewport_screenshot:
|
|
Capture a screenshot of the current Blender 3D viewport.
|
|
|
|
Parameters:
|
|
- max_size: Maximum size in pixels for the largest dimension (default: 800)
|
|
|
|
Returns the screenshot as an Image.

## Quick setup
|
|
|
|
1. Workspace: Compositing
|
|
2. Enable Use Nodes
|
|
3. Add Input > Image (load first frame; check Sequence)
|
|
4. Add Filter > Denoise
|
|
5. Connect: Image → Denoise → Composite
|
|
6. Set output folder in Output Properties
|
|
7. Render Animation
|
|
|
|
OpenImageDenoise-based GPU denoising is available in Blender 4.5.
|
|
|
|
If you need help setting it up or want the exact node setup, say which sequence to process.

check my node setup. the denoising seems really low quality.

Denoising an image sequence (PNGs) with only the Image connected; Normal and Albedo are missing, leading to lower quality. For best results, those passes are needed.
|
|
|
|
Options:
|
|
- If you have the source render with passes, plug Normal and Albedo into Denoise; HDR should match the source.
|
|
- If not, post-process denoising will be limited.

For better denoising quality:
|
|
|
|
1. Denoise node settings:
|
|
- Enable HDR only if using EXR/HDR
|
|
- Set Prefilter to FAST without denoising passes
|
|
- Prefilter ACCURATE requires Normal/Albedo passes
|
|
|
|
2. If you have the original blend: re-render with passes
|
|
- Render Properties → Passes → enable Denoising Data → Denoising Normal → Denoising Albedo
|
|
|
|
3. Alternative: Filter > Kuwahara (artistic smoothing) for post-process only
|
|
|
|
Render the compositor output to verify the result.

## The problem
|
|
The Denoise node had `use_hdr: False`, but the PNG images load as float (HDR data). This mismatch prevented denoising.
|
|
|
|
## What I fixed
|
|
1. Set `use_hdr: True` on the Denoise node to match the float inputs
|
|
2. Set `Prefilter: ACCURATE` for better quality
|
|
3. Set `Quality: HIGH`
|
|
4. Removed unused Render Layers node to avoid interference
|
|
|
|
## Your current setup
|
|
- Image sequence (PNG) → Denoise node → Reroute → Composite → FFMPEG output
|
|
- Denoise: HDR enabled, ACCURATE prefilter, HIGH quality
|
|
- Compositor enabled and active for rendering
|
|
|
|
Rendering the animation to FFMPEG will apply denoising to the MP4 output.
|
|
|
|
To verify, switch to the Compositor workspace and preview the Denoise → Viewer chain.
