<h1 id="blur_pix">blur_pix</h1>
|
||
|
||
<h2 id="description">Description</h2>
|
||
<p>Applies a pixelated blur effect to the input video, producing a blocky, low-resolution softening reminiscent of censored footage, retro 8-bit graphics, or lo-fi compression artifacts.<br />
|
||
This effect blends coarse pixelation with smooth blur, creating a stylized, abstracted visual aesthetic.</p>
|
||
|
||
<h2 id="purpose">Purpose</h2>
|
||
<p><code class="language-plaintext highlighter-rouge">blur_pix</code> is designed for artists who want to:</p>
|
||
<ul>
|
||
<li>intentionally degrade detail in a stylized way,</li>
|
||
<li>anonymize or obscure shapes without traditional Gaussian blur,</li>
|
||
<li>evoke retro-game pixelation,</li>
|
||
<li>add a surreal soft-block look to motion and texture,</li>
|
||
<li>produce a hybrid blur–pixelation effect ideal for glitch, collage, or experimental works.</li>
|
||
</ul>
|
||
|
||
<p>Because the module has <strong>no program-specific arguments</strong>, it is simple to use and highly compatible with all Videobeaux pipelines.</p>
|
||
|
||
<h2 id="how-it-works">How It Works</h2>
|
||
<ol>
|
||
<li><strong>Pixel Block Generation</strong><br />
|
||
The input frame is reduced to coarse pixel clusters using an internal scaling or mosaic-based algorithm.</li>
|
||
<li><strong>Softening Pass</strong><br />
|
||
A smoothing filter blends block edges to create a soft, dreamy, broken-resolution aesthetic.</li>
|
||
<li><strong>Unified Blur-Pixel Layer</strong><br />
|
||
The combined effect emphasizes abstraction over clarity, often producing painterly motion.</li>
|
||
<li><strong>Encoding</strong><br />
|
||
The final output is encoded using global Videobeaux codec settings (CRF, preset, pixel format, etc.).</li>
|
||
</ol>

<h2 id="technical-notes">Technical Notes</h2>
|
||
<ul>
|
||
<li>Pixelated blur behaves differently from Gaussian or box blur — detail is removed structurally, not just softened.</li>
|
||
<li>Compression interacts strongly with this effect, sometimes enhancing the aesthetic.</li>
|
||
<li>Works consistently regardless of resolution, though higher-resolution source footage yields more visible block abstraction.</li>
|
||
<li>Global Videobeaux settings (CRF, pixel format) can shift how “clean” or “dirty” the blocks appear.</li>
|
||
</ul>
|
||
|
||
<h2 id="recommended-usage">Recommended Usage</h2>
|
||
<ul>
|
||
<li>Music videos needing stylized abstraction.</li>
|
||
<li>Identity-obscuring or anonymization with artistic flair.</li>
|
||
<li>Retro-inspired or video-game-like sequences.</li>
|
||
<li>Experimental cinema, collage art, and painterly motion effects.</li>
|
||
<li>Background layers in VJ, projection, or live visual systems.</li>
|
||
</ul>
|
||
|
||
<h2 id="quality-tips">Quality Tips</h2>
|
||
<ul>
|
||
<li>Lower CRF (higher quality) preserves cleaner block edges.</li>
|
||
<li>Higher CRF increases compression noise — sometimes desirable for a gritty aesthetic.</li>
|
||
<li>Pair with <code class="language-plaintext highlighter-rouge">hash_fingerprint</code> or <code class="language-plaintext highlighter-rouge">bad_contrast</code> to stack analog/digital degradation.</li>
|
||
<li>Combine with <code class="language-plaintext highlighter-rouge">convert_dims</code> (square or portrait presets) for platform-optimized stylized loops.</li>
|
||
<li>Pre-processing with <code class="language-plaintext highlighter-rouge">gamma_fix</code> can improve highlight/midtone visibility inside blocky regions.</li>
|
||
</ul>
