|
||
<h2 id="description">Description</h2>
|
||
<p>Resizes the dimensions of a video to a specified width and height.<br />
|
||
This module performs a direct scale transformation, producing clean, predictable results for platform formatting, layout prep, or visual uniformity.</p>
|
||
|
||
<h2 id="purpose">Purpose</h2>
|
||
<p><code class="language-plaintext highlighter-rouge">resize</code> is designed for creators who want to:</p>
|
||
<ul>
|
||
<li>convert videos into specific resolution targets,</li>
|
||
<li>prepare assets for social platforms (square, vertical, widescreen),</li>
|
||
<li>normalize input dimensions before compositing in Lagkage,</li>
|
||
<li>upscale or downscale footage with direct pixel precision,</li>
|
||
<li>create clean formatting pipelines without aspect-ratio tricks.</li>
|
||
</ul>
|
||
|
||
<h2 id="how-it-works">How It Works</h2>
|
||
<ol>
|
||
<li><strong>Dimension Override</strong><br />
|
||
The user specifies:
|
||
<ul>
|
||
<li><code class="language-plaintext highlighter-rouge">new_width</code></li>
|
||
<li><code class="language-plaintext highlighter-rouge">new_height</code></li>
|
||
</ul>
|
||
</li>
|
||
<li><strong>Scaling Filter</strong><br />
|
||
FFmpeg’s scaler processes each frame to the requested resolution.</li>
|
||
<li><strong>Output Encoding</strong><br />
|
||
The final resized image is encoded using global Videobeaux settings (CRF, codec, pixel format, preset).</li>
|
||
</ol>

<h2 id="technical-notes">Technical Notes</h2>
|
||
<ul>
|
||
<li>This module <strong>does not</strong> enforce aspect-ratio preservation.</li>
|
||
<li>If the provided width and height do not match the original aspect ratio, the result will be stretched or squished — which may be desirable for stylized distortion.</li>
|
||
<li>For clean upscaling, combine with high-quality pixel formats (e.g., yuv444p or 10-bit formats) if your pipeline supports them.</li>
|
||
<li>Works well as a preprocessing step for LUTs, Lagkage, overlays, or dimension-specific delivery outputs.</li>
|
||
</ul>
|
||
|
||
<h2 id="recommended-usage">Recommended Usage</h2>
|
||
<ul>
|
||
<li>Creating platform-targeted versions:
|
||
<ul>
|
||
<li>1080×1920 (reels/stories/shorts)</li>
|
||
<li>1080×1080 (square grid formats)</li>
|
||
<li>1920×1080 (landscape)</li>
|
||
</ul>
|
||
</li>
|
||
<li>Normalizing assets before multi-layer compositing.</li>
|
||
<li>Preparing clips for generative art pipelines where exact sizes matter.</li>
|
||
<li>Upscaling stylized effects (e.g., painterly, glitch, smear) for high-res exports.</li>
|
||
</ul>
|
||
|
||
<h2 id="quality-tips">Quality Tips</h2>
|
||
<ul>
|
||
<li>For crisp results, resize <strong>before</strong> applying heavy effects and grading.</li>
|
||
<li>For a degraded or lo-fi look, resize <strong>after</strong>, which amplifies artifacts.</li>
|
||
<li>Use exact values that match your layout or platform’s requirements.</li>
|
||
<li>Pair with <code class="language-plaintext highlighter-rouge">convert_dims</code> when you want aspect-ratio intelligence; use <code class="language-plaintext highlighter-rouge">resize</code> when you want exact pixel control.</li>
|
||
<li>For upscaling beyond 2×, consider preprocessing with <code class="language-plaintext highlighter-rouge">gamma_fix</code> or <code class="language-plaintext highlighter-rouge">tonemap_hdr_sdr</code> to stabilize tonal fidelity before scaling.</li>
