# Built-in rules (/docs/rules) Every rule PPROLint ships with, and its rule file. {/* Generated by scripts/generate-docs.ts. Do not edit. */} PPROLint ships with 29 rules. Each is a rule file like the ones you write: open one to see its options and the complete file, a good starting point for your own rule. ## Static [#static] | Rule | Id | Severity | Reports | | :------------------------------------------------------------------------------------ | :------------------------------------- | :------- | :--------------------------------------------------------------------------------- | | [Audio gaps](/docs/rules/no-audio-gaps) | `no-audio-gaps` | info | Reports ranges of the work area where no audio clip is audible. | | [Clips outside the work area](/docs/rules/no-clips-outside-work-area) | `no-clips-outside-work-area` | warning | Reports clips entirely before the sequence in point or after its out point. | | [Disabled clips](/docs/rules/no-disabled-clips) | `no-disabled-clips` | warning | Reports disabled clips, which are skipped on playback and export. | | [Duplicate effects](/docs/rules/no-duplicate-effects) | `no-duplicate-effects` | info | Reports clips with the same effect applied more than once. | | [Empty markers](/docs/rules/no-empty-markers) | `no-empty-markers` | info | Reports markers with neither a name nor a comment. | | [Empty tracks](/docs/rules/no-empty-tracks) | `no-empty-tracks` | info | Reports tracks without clips. | | [Invisible video clips](/docs/rules/no-invisible-video-clips) | `no-invisible-video-clips` | warning | Reports video clips at 0 % opacity or 0 % scale, which render nothing. | | [Markers outside the work area](/docs/rules/no-markers-outside-work-area) | `no-markers-outside-work-area` | warning | Reports markers after the last clip or outside the sequence in/out range. | | [Muted tracks](/docs/rules/no-muted-tracks) | `no-muted-tracks` | warning | Reports muted tracks that carry clips, which are left out of the export. | | [Offline media](/docs/rules/no-offline-media) | `no-offline-media` | error | Reports clips whose source media is offline. | | [Out-of-sync audio and video](/docs/rules/no-out-of-sync-av) | `no-out-of-sync-av` | warning | Reports audio clips offset from the video clip of the same source they play under. | | [Partial adjustment layer coverage](/docs/rules/no-partial-adjustment-layer-coverage) | `no-partial-adjustment-layer-coverage` | info | Reports adjustment layers whose start or end falls inside a clip below them. | | [Silent audio clips](/docs/rules/no-silent-audio-clips) | `no-silent-audio-clips` | warning | Reports audio clips whose volume is set to silence. | | [Subframe video edits](/docs/rules/no-subframe-video-edits) | `no-subframe-video-edits` | warning | Reports clip edges and sequence in/out points that are not on a frame boundary. | | [Tiny clips](/docs/rules/no-tiny-clips) | `no-tiny-clips` | warning | Reports clips only a few frames long, usually leftovers of a trim. | | [Video gaps](/docs/rules/no-video-gaps) | `no-video-gaps` | warning | Reports ranges of the work area where no video clip is visible (black frames). | | [Zero-duration clips](/docs/rules/no-zero-duration-clips) | `no-zero-duration-clips` | error | Reports clips whose end is not after their start. | | [Scale range](/docs/rules/scale-range) | `scale-range` | info | Reports video clips scaled outside the allowed range. | ##
