|
||
|
||
<h2 id="description">Description</h2>
|
||
<p>Extracts individual frames from a video file and saves them as image files (typically PNG).<br />
|
||
Ideal for analysis, archival, animation workflows, visual debugging, and creating frame-based artwork.</p>
|
||
|
||
<h2 id="purpose">Purpose</h2>
|
||
<p><code class="language-plaintext highlighter-rouge">extract_frames</code> gives creators a fast and predictable way to output every frame (or selected frames via global videobeaux options) as standalone image files.<br />
|
||
This is useful for:</p>
|
||
<ul>
|
||
<li>animation and rotoscoping workflows,</li>
|
||
<li>ML dataset preparation,</li>
|
||
<li>glitch-art and frame-painting processes,</li>
|
||
<li>shot-by-shot inspection or QC,</li>
|
||
<li>archival still-frame extraction.</li>
|
||
</ul>
|
||
|
||
<h2 id="how-it-works">How It Works</h2>
|
||
<ol>
|
||
<li><strong>Frame Decoding</strong><br />
|
||
Video frames are decoded sequentially.</li>
|
||
<li><strong>Image Export</strong><br />
|
||
Each frame is exported as its own image file using the globally configured pixel format and image output settings.</li>
|
||
<li><strong>Naming Convention</strong><br />
|
||
Frames are typically numbered sequentially (e.g., <code class="language-plaintext highlighter-rouge">000001.png</code>, <code class="language-plaintext highlighter-rouge">000002.png</code>, etc.), depending on videobeaux output rules.</li>
|
||
<li><strong>Output Directory</strong><br />
|
||
The destination directory is defined by global videobeaux settings (<code class="language-plaintext highlighter-rouge">--outfile</code>, mapping rules, etc.).</li>
|
||
</ol>
|

||
<h2 id="program-template">Program Template</h2>

|
||
-i input.mp4 \

-o output.mp4
|
||
</code></pre></div></div>
|
||
|
||
<h2 id="arguments">Arguments</h2>
|
||
<ul>
|
||
<li><em>(No program-specific arguments — this tool relies entirely on global videobeaux settings such as image format, numbering, and frame selection.)</em></li>
|
||
</ul>
|
||
|
||
<h2 id="real-world-example">Real World Example</h2>
|

<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>videobeaux -P extract_frames \
|
||
-i myvideo.mp4 \
|
||
-o extract_frames_styled.mp4
|
||
</code></pre></div></div>
|

|
||
<h2 id="technical-notes">Technical Notes</h2>
|
||
<ul>
|
||
<li>PNG is the default format due to lossless quality, but other formats may be used depending on global configuration.</li>
|
||
<li>Large videos may produce thousands of frames; ensure adequate disk space.</li>
|
||
<li>Frame extraction is decode-limited — higher-resolution videos take longer per frame.</li>
|
||
<li>If frames are dropped or duplicated in the source video stream, extraction will preserve exactly what the decoder receives.</li>
|
||
<li>Good for use ahead of per-frame manipulation tools, compositing, or generative workflows.</li>
|
||
</ul>
|
||
|
||
<h2 id="recommended-usage">Recommended Usage</h2>
|
||
<ul>
|
||
<li>Creating frame sequences for animation, compositing, or painting.</li>
|
||
<li>Building datasets for computer vision or machine learning.</li>
|
||
<li>Inspecting motion continuity, exposure behavior, or compression artifacts.</li>
|
||
<li>Generating image sequences for later re-import into editing or FX tools.</li>
|
||
</ul>
|
||
|
||
<h2 id="quality-tips">Quality Tips</h2>
|
||
<ul>
|
||
<li>Use PNG for archival quality; JPG for lightweight previews.</li>
|
||
<li>If color accuracy is critical, set a high-bit-depth pixel format globally (e.g., <code class="language-plaintext highlighter-rouge">rgb48le</code>).</li>
|
||
<li>Use SSD storage for significantly faster write speeds on large sequences.</li>
|
||
<li>When extracting for VFX, ensure your project frame rate matches the video’s native frame rate to avoid timing mismatch.</li>
|
||
</ul>
