I successfully failed at one-shot-ing a video codec like h.264
Read an article yesterday about the H.264 codec increasing their licensing fee by an astronomical amount. And as always, my first shot was how hard could it be to try and build a codec which could be that efficient. I've personally been on a drive to improve my ability to one-shot complex features, products, or make even surgical changes. It's been a few months since I've been doing that, and honestly, results have been great for both work and work/life balance. This was a fun experiment. It burned through tokens, but it helped me identify some more improvements I could make to my…

What it does
Sinter — An experimental, fully vibecoded video codec built on lapped transforms and perceptual vector quantization. No deblocking filters, no legacy architecture. Achieves luma quality within 1 dB of H.264 on a fundamentally different design. - GitHub - DheerG/libsinter: Sinter — An experimental, fully vibecoded video codec built on lapped transforms and perceptual vector quantization. No deblock
An experimental, vibecoded video codec built from scratch using Claude Code agent teams. Explores lapped transforms, perceptual vector quantization (PVQ), and rANS entropy coding as a patent-free alternative to the H.264/H.265 lineage. This was a learning experiment , not a production codec. The goal was to test one-shot agent team workflows on a domain I had zero prior experience in — and to see how far a simulated expert team could push a novel architecture. Write-up: One-Shot Wonder | Claude Agent Teams At comparable luma quality (~49 dB): 18.6x larger than H.264. The architecture produces competitive perceptual quality but cannot match H.264's compression efficiency without adopting the…from github.com

Hi HN, I’m Ashu, founder of VideoDB. I’ve spent a big chunk of my life building video infrastructure. Not video creation. Video plumbing. The stuff you only learn after production breaks: timebases, VFR, keyframes, audio sync drift, container quirks, partial uploads, live streams, retries, backpressure, codecs, ffmpeg flags, cost blowups, and “why is this clip unseekable on one player but fine on another”. This week we shared VideoDB Skills, a skill pack that lets AI agents call those infra primitives directly, instead of you wiring pipelines with screenshots plus FFmpeg glue. Repo:…
Make AI motion videos with textFeb 2026 · framecall.com · ▲6Saw the remotion claude skills launch earlier, and honestly even though I was surprised how decent some of the results turned out to be I ended up never trying it out with claude code because I knew I'd have to setup remotion, bundler etc and if I was already doing it once I thought I might as well turn it into a site where anyone could just write messages and get a video without any prerequisites. I also know Claude Code is not something everyone has and setting up remotion is a pain. And one of the biggest lessons I learned from this whole experience is that Opus is actually not that good…
I'm doing a video series about building a C++ IDE from scratch2019 · youtube.com · ▲23- IBI built an idea to video app2024 · frameloop.ai · ▲8
Frameloop is an AI-powered video creation and automation tool, that turns ideas into publishable videos within seconds. I've been working on this for past 4 months now, and have few paying customers as well. Most of them are individual creators, and about 20% are businesses. I'd like to focus more on business users going forwards, and am building branded video features for businesses. There are many other tools at this point, but my focus has been to focus on great UX, and giving users a really good first draft, which is easily editable. And I think that focus is what differentiates us. Try…
GIF.new2025 · gif.new · ▲18i use GIFs a lot in my personal/professional life and so I'm pretty passionate about the topic :P about a month ago I found out that this domain was available and couldn't believe it. Waited a good 3 weeks to pull the trigger on buying it (which, btw is hella expensive by default) and in the meantime, hopped from one idea to another on what it should house. original idea was to build some kind of prompt-to-GIF service but very soon realised that i can't sustain the AI bill on my budget (top contender was to use runway). then came the idea of animating charts from data (obvious: i work…
Built an AI ad generator and ran $9K of FB ads with itMar 2026 · admakeai.com · ▲6Been in the AI image gen space since 2023, before even GPT image gen was a thing, and after spending ~9K on Facebook ads for my own projects (made a video about that actually) I realized the thing I kept getting stuck on was the creatives themselves. I'm horrible at making reels-type video ads and Canva even with templates is surprisingly complicated for ad-specific stuff, plus everything ends up looking the same as everyone else using the same templates. Made a video going into detail about the full FB ads journey if anyone's interested:…

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
