The fastest way to build predictable, sustainable growth is learning which signals deserve your focus and which are just noise.

Experiment Loudly. Learn Quietly.

AI can boost short-term output while shrinking long-term competence. This study shows why—and the AI workflows that protect learning.

AI Assistants Can Quietly Kill Skill Growth

<p><em>This is a simplified guide to an AI model called <a href="https://www.aimodels.fyi/models/fal/ltx-2-19b-distilled-extend-video-fal-ai?utm_source=hackernoon&utm_medium=referral">ltx-2-19b/distilled/extend-video</a> maintained by <a href="https://www.aimodels.fyi/creators/fal/fal-ai?utm_source=hackernoon&utm_medium=referral">fal-ai</a>.

<h2>Model overview</h2>
<p><code>ltx-2-19b/distilled/extend-video</code> is a specialized tool from <a href="https://aimodels.fyi/creators/fal/fal-ai?utm_source=hackernoon&utm_medium=referral">fal-ai</a> designed to extend videos by generating synchronized audio. This distilled version of LTX-2 provides a streamlined approach to video-to-audio generation. If you need to extend video content with different model versions, alternatives like <a href="https://aimodels.fyi/models/fal/ltxv-13b-098-distilled-extend-fal-ai?utm_source=hackernoon&utm_medium=referral">ltxv-13b-098-distilled/extend</a> and <a href="https://aimodels.fyi/models/fal/ltx-video-13b-distilled-extend-fal-ai?utm_source=hackernoon&utm_medium=referral">ltx-video-13b-distilled/extend</a> offer different architectural approaches to the same task.</p>
<h2>Capabilities</h2>
<p>This model generates audio that matches existing video content, allowing creators to add synchronized soundtracks to silent or partially dubbed videos. The distilled nature means it processes requests with reduced computational overhead compared to full-scale versions, making it practical for production workflows. The audio generation adapts to the visual content, ensuring temporal alignment and coherence with on-screen events and scene transitions.</p>
<h2>What can I use it for?</h2>
<p>Content creators can use this model to add professional audio layers to silent footage, completing video projects that lack proper sound design or dialogue. Educational institutions might enhance instructional videos with narration. Marketing teams can extend raw video captures with branded audio elements. The distilled version makes these applications accessible without requiring extensive hardware resources. Understanding how this fits into broader audio synthesis approaches can benefit from research into <a href="https://aimodels.fyi/papers/arxiv/lova-long-form-video-to-audio-generation?utm_source=hackernoon&utm_medium=referral">long-form video-to-audio generation</a> techniques.</p>
<h2>Things to try</h2>
<p>Start by testing with simple videos where the visual narrative is clear and straightforward, as the model will generate audio that corresponds to those visual cues. Experiment with different video lengths to understand the model's optimal range for audio generation. Try feeding it videos with distinct visual moments or scene changes to see how the audio responds to those transitions. Compare the generated audio quality against your original footage to identify where the model excels and where manual adjustments might enhance results.</p>
