MadSync - Music Video Editor

Auto-lyrics, beats, stems. Offline and private. $49 once

What it does

MadSync is a Windows music video editor that cuts footage to the beat for you. Drop clips on the timeline and they snap to the drums. Auto-lyrics turns your song into timed karaoke captions, full-sentence or word-by-word. Stem separation pulls out vocals and drums. Everything runs on your PC: songs and footage never leave your machine, and editing works offline. Free demo included: the full app with a watermark and 60s export cap. One-time $49 unlocks clean exports, no subscription.

    I went nuts on Sunday after stumbling on this animator script for the automatic branch: https://github.com/Animator-Anon/Animator And then it's a ton of keyframing. I also found that the timings all have to be earlier than the timestamp you want to account for how long it takes to denoise to your new scene - so like .4 gives smoother but longer, .7 is snappy. To get stuff to keep showing up and stay dynamic you can zoom out continuously, it needs a UI, badly. If you're on windows you'll need ffmpeg too. I watched this when it came out last week:…

  • I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

  • Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

    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.
