Lorem.video – placeholder videos generated from URLs
At work I have to deal with videos in different resolutions. We're also switching from H.264 to AV1, so I needed a quick way to test our video pipeline with different formats and sizes. I created lorem.video - a service that generates placeholder videos directly from the URL. For example: https://lorem.video/1280x720_h264_20s_30fps You control everything via the URL path: resolution, duration, codec (h264/h265/av1/vp9), bitrate, and fps. Videos are cached after first generation, so subsequent requests are instant. Built it in Go using FFmpeg for encoding.…
What it does
In the maker’s words, at launch
At work I have to deal with videos in different resolutions. We're also switching from H.264 to AV1, so I needed a quick way to test our video pipeline with different formats and sizes.

Videos are cached after first generation, so subsequent requests are instant. Built it in Go using FFmpeg for encoding. Generation runs in a nice'd process so it doesn't interfere with serving cached videos. Running on a cheap VPS. MIT licensed, source on GitHub: https://github.com/guntisdev/lorem-video

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…
