# Output inspection: Video Upscaling and Compression Artifacts

Blocking and ringing in a heavily compressed source can become more visible after enlargement. Review the result at its intended size and inspect details that previews can hide.

## 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
Video upscaling can amplify compression artifacts like blocking and ringing. To ensure quality, compare the final output to the original source at the intended display size.

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

## Key takeaways
- Blocking and ringing artifacts in compressed sources become more visible after upscaling.
- Reviewing output at the intended display size is necessary to identify hidden details.
- The recommended workflow requires preserving the original input and noting its limitations.
- Settings and uncertainty should be recorded before reusing any upscaled result.

## Insights
- Enlarging video can exacerbate existing compression artifacts like blocking and ringing.
- Previews often hide critical details that only become apparent at the intended final display size.
- A repeatable workflow is a reference tool rather than a replacement for direct human verification of source and output.

## Open questions / gaps
- What specific criteria define the smallest change that addresses a task?
- How should one quantify or document uncertainty during the recording phase?
