<h1 id="bad_contrast">bad_contrast</h1>
|
|
|
|
<h2 id="description">Description</h2>
|
|
<p>Applies a “bad contrast” visual effect to the video, intentionally degrading tonal balance, highlight rolloff, shadow separation, and midtone neutrality.<br />
|
|
The result simulates low-quality analog transfers, misconfigured broadcast equipment, degraded VHS dubs, or broken grading pipelines.</p>
|
|
|
|
<h2 id="purpose">Purpose</h2>
|
|
<p><code class="language-plaintext highlighter-rouge">bad_contrast</code> exists as a lightweight, stylized degradation tool for artists who want to:</p>
|
|
<ul>
|
|
<li>introduce tonal instability or harsh contrast,</li>
|
|
<li>mimic analog-era video duplication artifacts,</li>
|
|
<li>add mood through blown-out highlights or crushed shadows,</li>
|
|
<li>create an intentionally incorrect exposure/contrast aesthetic,</li>
|
|
<li>emphasize “bad video” texture in music videos, glitch art, or experimental film.</li>
|
|
</ul>
|
|
|
|
<h2 id="how-it-works">How It Works</h2>
|
|
<ol>
|
|
<li><strong>Contrast Manipulation</strong><br />
|
|
The module applies an internally defined filter chain that exaggerates or distorts normal contrast response.</li>
|
|
<li><strong>Highlight / Shadow Distortion</strong><br />
|
|
Highlights may appear clipped or harsh; shadows may compress or posterize.</li>
|
|
<li><strong>Midtone Bias</strong><br />
|
|
The effect may introduce incorrect gamma or uneven tonal mapping to create a “broken” look.</li>
|
|
<li><strong>Encoding</strong><br />
|
|
Final output uses global Videobeaux codec, pixel format, and CRF settings.</li>
|
|
</ol>

<h2 id="technical-notes">Technical Notes</h2>
|
|
<ul>
|
|
<li>The exact look depends partly on global Videobeaux encoding settings.</li>
|
|
<li>Output may exhibit blown-out whites, crushed blacks, or tonal banding.</li>
|
|
<li>Not intended for corrective workflows — this is a purely stylistic degradation.</li>
|
|
<li>Works particularly well on motion-heavy or color-rich footage.</li>
|
|
<li>As with all destructive effects, applying <code class="language-plaintext highlighter-rouge">bad_contrast</code> early in a pipeline will influence all later operations.</li>
|
|
</ul>
|
|
|
|
<h2 id="recommended-usage">Recommended Usage</h2>
|
|
<ul>
|
|
<li>Broken-TV or analog-digital hybrid aesthetics.</li>
|
|
<li>Glitch art, experimental cinema, and abstract video installations.</li>
|
|
<li>Distressing otherwise clean digital footage.</li>
|
|
<li>Music videos seeking stylized degradation.</li>
|
|
<li>As an “imperfection layer” paired with other Videobeaux modules (e.g., <code class="language-plaintext highlighter-rouge">bad_animation</code>, <code class="language-plaintext highlighter-rouge">hash_fingerprint</code>).</li>
|
|
</ul>
|
|
|
|
<h2 id="quality-tips">Quality Tips</h2>
|
|
<ul>
|
|
<li>Apply at the end of a chain to maximize visible distortion.</li>
|
|
<li>Pair with lower CRF values if you want compression artifacts to interact with tonal distortion.</li>
|
|
<li>Use on footage with clear highlight/shadow separation for the strongest effect.</li>
|
|
<li>Combine with LUTs or <code class="language-plaintext highlighter-rouge">lut_apply</code> to push contrast into more extreme color spaces.</li>
|
|
<li>For a VHS-like aesthetic, consider pairing with <code class="language-plaintext highlighter-rouge">bad_contrast</code> + <code class="language-plaintext highlighter-rouge">convert_dims</code> (480p or 720hd presets).</li>
|
