# Reuse preparation: Video Upscaling and Compression Artifacts

Blocking and ringing in a heavily compressed source can become more visible after enlargement. Save the input assumptions, chosen settings, output version, and any remaining uncertainty.

## Practical review sequence

1. Preserve the original input and note its important limitations.
2. Apply the smallest change that addresses the current task.
3. Compare the result with the source at the intended display size.
4. Record settings and uncertainty before the result is reused.

This public workflow document covers one bounded quality-control task. It is intended as a repeatable reference rather than a substitute for checking the source material and the final output directly.

## Summary
Enlarging heavily compressed video can amplify blocking and ringing artifacts. To manage this, follow a systematic review process that documents all settings and input limitations before finalizing the output.

## Themes
- Video upscaling workflow
- Quality control processes
- Compression artifact management

## Key takeaways
- Blocking and ringing artifacts in compressed sources become more prominent after enlargement.
- The workflow requires preserving the original input and noting its limitations before processing.
- Users should apply the smallest change necessary to complete the task.
- The final result must be compared against the source at the intended display size.
- Settings and uncertainties must be recorded before the output is reused.

## Insights
- Upscaling can inadvertently amplify existing compression artifacts like blocking and ringing.
- The document emphasizes documentation of process variables as a core component of the quality control task.
- A minimal intervention approach is preferred over aggressive processing to maintain source integrity.

## Open questions / gaps
- What specific criteria define the smallest change for different types of compression artifacts?
