Netflix alone reportedly spends around a billion dollars a year on cloud infrastructure with AWS, and most of that cost comes down to one stubborn problem: video files are gigantic, and shrinking them without making them look worse is genuinely hard.</p> <p class="wp-block-paragraph">Vidaio, which runs as Subnet 85 on the Bittensor network, just put up benchmark numbers that say it solves that problem better than anyone else currently does. Not better than a few startups. Better than the biggest names in the industry. And just like that, a small decentralized subnet has built the most efficient video compression available right now, and the way they got there is something only Bittensor makes possible.</p> <div id="ez-toc-container" class="ez-toc-v2_0_76 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction"> <div class="ez-toc-title-container"> <p class="ez-toc-title" style="cursor:inherit">Table of Contents</p> <span class="ez-toc-title-toggle"><a href="#" class="ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle" aria-label="Toggle Table of Content"><span class="ez-toc-js-icon-con"><span class=""><span class="eztoc-hide" style="display:none;">Toggle</span><span class="ez-toc-icon-toggle-span"><svg style="fill: #999;color:#999" xmlns="http://www.w3.org/2000/svg" class="list-377408" width="20px" height="20px" viewBox="0 0 24 24" fill="none"><path d="M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z" fill="currentColor"></path></svg><svg style="fill: #999;color:#999" class="arrow-unsorted-368013" xmlns="http://www.w3.org/2000/svg" width="10px" height="10px" viewBox="0 0 24 24" version="1.2" baseProfile="tiny"><path d="M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z"/></svg></span></span></span></a></span></div> <nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class="ez-toc-link ez-toc-heading-1" href="https://taodaily.io/this-bittensor-subnet-built-the-best-video-compression-in-the-world/#The_problem_nobody_outside_the_industry_thinks_about" >The problem nobody outside the industry thinks about</a></li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class="ez-toc-link ez-toc-heading-2" href="https://taodaily.io/this-bittensor-subnet-built-the-best-video-compression-in-the-world/#How_quality_actually_gets_measured" >How quality actually gets measured</a></li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class="ez-toc-link ez-toc-heading-3" href="https://taodaily.io/this-bittensor-subnet-built-the-best-video-compression-in-the-world/#The_benchmark_that_turns_heads" >The benchmark that turns heads</a></li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class="ez-toc-link ez-toc-heading-4" href="https://taodaily.io/this-bittensor-subnet-built-the-best-video-compression-in-the-world/#Why_this_could_only_happen_on_Bittensor" >Why this could only happen on Bittensor</a></li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class="ez-toc-link ez-toc-heading-5" href="https://taodaily.io/this-bittensor-subnet-built-the-best-video-compression-in-the-world/#From_a_tool_to_an_operating_system" >From a tool to an operating system</a></li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class="ez-toc-link ez-toc-heading-6" href="https://taodaily.io/this-bittensor-subnet-built-the-best-video-compression-in-the-world/#Why_the_timing_matters" >Why the timing matters</a></li></ul></nav></div> <h2 class="wp-block-heading"><span class="ez-toc-section" id="The_problem_nobody_outside_the_industry_thinks_about"></span>The problem nobody outside the industry thinks about<span class="ez-toc-section-end"></span></h2> <figure class="wp-block-image size-full"><img loading="lazy" decoding="async" width="960" height="684" src="https://taodaily.io/wp-content/uploads/2026/06/image-182.png" alt="" class="wp-image-20818" srcset="https://taodaily.io/wp-content/uploads/2026/06/image-182.png 960w, https://taodaily.io/wp-content/uploads/2026/06/image-182-300x214.png 300w, https://taodaily.io/wp-content/uploads/2026/06/image-182-768x547.png 768w" sizes="(max-width: 960px) 100vw, 960px" /><figcaption class="wp-element-caption">Source: <a href="https://www.statista.com/chart/2627/internet-users-watching-online-video-every-day/?srsltid=AfmBOopzATOs8Fnltb0bal_DZg9oPr2hgofcbMwPIscB5hwINurki_pI">Statista</a></figcaption></figure> <p class="wp-block-paragraph">Video is the heaviest thing on the internet. It already makes up the overwhelming majority of all internet traffic, and the volume keeps climbing as more of it gets created, uploaded, and streamed.</p> <p class="wp-block-paragraph">AI has poured gasoline on this. With a single prompt, someone can now generate a ninety minute film and push it to the cloud, and the infrastructure underneath was never designed for that kind of flood.</p> <p class="wp-block-paragraph">The founder behind Vidaio spent more than two decades in traditional video, working across post production and distribution for the likes of Sony, Sky, Canal +, etc. He saw the same wall everywhere. He also ran into it firsthand building the first video-on-demand platform in Nigeria, where bad bandwidth and limited storage made streaming high-quality video almost impossible. The fix he wanted, high quality content at a tiny file size, did not exist yet because the technology was not there.</p> <p class="wp-block-paragraph">This problem is simple to imagine and brutally hard to solve. You want a smaller file, but you do not want the viewer to notice any drop in quality. Push compression too far and the picture turns blocky and smeared. Stop too early and you are still paying to store and stream bytes you did not need. The entire solution is finding the smallest possible file that the human eye still reads as flawless.</p> <h2 class="wp-block-heading"><span class="ez-toc-section" id="How_quality_actually_gets_measured"></span>How quality actually gets measured<span class="ez-toc-section-end"></span></h2> <p class="wp-block-paragraph">To know whether compression is any good, you need an honest way to measure quality that matches how people perceive video. The industry standard for this is <a href="https://github.com/Netflix/vmaf">VMAF</a>, a scoring system Netflix built that blends human perception modeling with machine learning to rate a video on a quality scale.</p> <p class="wp-block-paragraph">A VMAF score around 93 is essentially perfect to the human eye. You will not be able to spot any degradation at that level.</p> <p class="wp-block-paragraph">So the real test is this: lock every compression method to the same VMAF score, meaning every output looks equally good, then see whose file is smallest. Same perceived quality for everyone, and the winner is whoever gets there with the fewest bytes. That is the apples to apples comparison, and it is exactly the test Vidaio ran.</p> <h2 class="wp-block-heading"><span class="ez-toc-section" id="The_benchmark_that_turns_heads"></span>The benchmark that turns heads<span class="ez-toc-section-end"></span></h2> <figure class="wp-block-image size-large"><img loading="lazy" decoding="async" width="1024" height="410" src="https://taodaily.io/wp-content/uploads/2026/06/image-180-1024x4
