This process involves finalizing the rendered frame, applying any necessary post-processing, and saving the output to the specified location.

Frame Output Breakdown

1. Render Pass Management

• Combine Render Passes: If the rendering process generated multiple passes (e.g., beauty, shadow, reflection), these passes are combined to create the final image.
• Pass Processing: Each pass may undergo specific processing, such as tone mapping or exposure adjustment, before being combined.

2. Post-Processing

• Color Correction: Adjust color balance, brightness, contrast, and saturation to achieve the desired look.
• Gamma Correction: Apply gamma correction to ensure correct display on different devices.
• Tone Mapping: Convert the high dynamic range (HDR) image to a low dynamic range (LDR) image if necessary.
• Special Effects: Apply additional effects like bloom, lens flares, and vignetting.

3. File Formatting

• Determine Output Format: Choose the file format based on user settings (e.g., PNG, JPEG, EXR).
• Bit Depth and Compression: Set the bit depth (e.g., 8-bit, 16-bit) and apply compression if needed (e.g., lossy for JPEG, lossless for PNG).

4. Metadata Embedding

• Embed Metadata: Add metadata to the image file, such as render settings, frame number, and scene information.

5. Image Saving

• Set Output Path: Define the path where the final image will be saved.
• Save Image: Save the image to the specified location with the correct file naming convention.

6. Quality Check

• Automated Checks: Perform automated checks to ensure the output image meets quality standards (e.g., no missing textures, correct color range).
• Manual Review: Optionally, a manual review process may be conducted to verify the image quality.

7. Uploading and Distribution

• Central Storage Upload: Upload the final image to a central storage system if required.
• Client Distribution: Distribute the image to the client or the next stage in the pipeline, such as compositing or editing.

Example Frame Output Workflow

Scenario: Saving a final frame of an animation using EXR format.

1. Render Pass Management
   • Combine beauty pass, shadow pass, and reflection pass.
   • Apply exposure adjustment to each pass before combining.
2. Post-Processing
   • Color Correction: Adjust brightness and contrast to enhance the image.
   • Gamma Correction: Apply gamma correction for accurate display.
   • Tone Mapping: Convert HDR image to LDR for final output.
   • Special Effects: Add a subtle bloom effect to bright areas.
3. File Formatting
   • Output Format: EXR for high dynamic range.
   • Bit Depth: Set to 16-bit for detailed color information.
   • Compression: Apply lossless compression to reduce file size.
4. Metadata Embedding
   • Embed metadata such as frame number, render settings, and scene name.
5. Image Saving
   • Set Output Path: /renders/ProjectX/frame_001.exr.
   • Save Image: Save the EXR file to the specified path.
6. Quality Check
   • Automated Checks: Verify no missing textures and correct color range.
   • Manual Review: Optional manual review to ensure high quality.
7. Uploading and Distribution
   • Central Storage Upload: Upload frame_001.exr to central storage for backup.
   • Client Distribution: Send the image file to the client or compositing team.
