If the platform never serves a 4K master for that post, videngineer cannot invent one. ## What quality badges mean | Badge | Meaning | | -------------- | ----------------------------------------------------------------------- | | Source quality | The app is showing the quality of the pulled source | | 4K | A higher-quality master was available and used or unlocked | | Low quality | The source came through at a lower resolution or weaker preview quality | Use these badges when deciding whether a cut is production-reference quality. A low-quality source can still teach structure, pacing, hooks, and sound, but it may be weaker for frame-level visual study. ## Troubleshooting quality * Try upload when a platform pull is low-quality and you have the original file. * Use Power if you need automatic 4K masters across a research set. * On Pro, use credits only when the higher-quality master matters for the job. * If a public platform blocks the best source, the report may still complete with the best available pull. ## Related pages Where clip quality matters most.
