Why Video Download Quality Is Limited
The list of download qualities begins with what the source exposes for that URL at analysis time. Lynvado filters the list; it does not manufacture higher resolutions.
The upload may never have had that resolution
A 720p upload cannot produce a native 1080p or 4K download. Platforms can also remove or delay higher-resolution processing after an upload.
Public playback can differ from the master
Creators and platforms may restrict original downloads, serve different renditions by device or region, or require authentication for particular streams. Lynvado uses only anonymously accessible public formats.
Some formats are filtered for safety
Malformed, duplicate, live-only, DRM-protected, and unsupported protocol entries are removed. File-size and duration limits can also make a particular option unavailable for preparation.
Why upscaling is not an answer
Upscaling makes a larger frame but does not restore real detail. An honest 720p label is more useful than a synthetic 4K claim.
