# Output inspection: Comparing Before and After Frames

Review matched frames at the same timestamp and zoom level so sharpness comparisons are fair. 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
To ensure fair quality control, compare output frames against the original source at the intended display size and zoom level. Follow a structured review sequence that emphasizes minimal changes and careful documentation of settings.

## Themes
- Video quality control
- Output inspection workflow
- Upscaling best practices

## Key takeaways
- Matched frames must be compared at the same timestamp and zoom level.
- The inspection process requires reviewing results at their intended display size.
- Settings and uncertainty should be recorded before reusing any output.
- The workflow is a repeatable reference and not a substitute for direct source material verification.

## Insights
- Comparing frames at different zoom levels leads to unfair sharpness assessments.
- Previews often obscure critical details that only appear at the intended final display size.
- The workflow emphasizes minimal intervention to address specific tasks rather than broad processing.

## Open questions / gaps
- What specific metrics define an acceptable level of uncertainty during the recording phase?
