Hey HN! I built Topic2Manim to automate the creation of educational videos like those from 3Blue1Brown. The workflow is simple: 1. Give it any topic (e.g., "how ChatGPT works") 2. An LLM generates an educational script divided into scenes 3. LLM generates Manim code for each scene 4. FFmpeg concatenates everything into a final video Currently working on TTS integration for narration! Would love feedback on the approach and ideas for the TTS integration

Hello HN! I’m a bachelors student pursuing Artificial Intelligence, Robotics and Signal processing and during the year I had the goal to build my first AI Tool and launch it. I got inspired by how capable Whisper is, and combined the Whisper CPP Bindings along with FFMPEG.Wasm to create a tool that is capable of transcribing and captioning video files that contain one or more video tracks. Along with that, I’ve also added the support for transcribing audio files with the option to export those outputs as .SRT, .WebVTT or simply a text file. All done privately on a user’s web browser with…

There isn't a 3B1B-style video explanation for every topic. But you can make your own from a single prompt with my API.

Hey HN! I built Transcrib.ee to help me generate transcripts for lectures on YouTube with no captions, especially multilingual lectures. I was constantly frustrated with videos that had no transcripts or inaccurate ones, so I built a tool and decided to share it with everyone. This tool uses Groq (an AI inference engine that's different from Grok and offers very fast processing) and OpenAI's Whisper model (really accurate in multilingual) to quickly transcribe any YouTube video, regardless of the language. It's been a game-changer for my studies! To make it even faster, I created a Chrome…

Saw 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 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:…

Live demo here: http://fonctionlabs.com:8000 Similarly to aka_sh (guess we were working parallelly on similar topics), I created with my brother a chainlit-based webapp, which summarizes Youtube videos in order to gain time. It works as an RAG-based LLM, and is very light in the sense that it does not use RAG libraries like langchain or llamaindex. You can use it with your own OpenAI API key. It also supports local models like Mistral, or Llamma. It is ofc open-source, and you can deploy with Docker if you choose. Some of the next steps are: - using whisper to be able to compute a…

Initially, I was interested in using YouTube videos to learn languages using the simple shadowing technique. It sounds fancy, but it's simply listening and repeating. However, I found it pretty inconvenient to use the vanilla YouTube player to replay video parts. Especially when I needed to do it several times. Later I figured out that it's pretty handy to also practice instruments, given how much material is in there. Not just for mimicking songs but also for better following tutorials. So the idea is simple, you can save clips you want to practice to loop as many times as you want and come…

Recently there were some changes to the Twitter algorithm and one of the most important ones was boosting video content even more in the feed, which got me thinking: "Why shouldn't we benefit from the algo changes and get a boost every time we are sharing some visuals?" So I spent the weekend building a tool that: - Turns your images into videos - Has 30 beautiful animated gradients that we can pick from - Is completely FREE I'd love to know your thoughts about it!

Hey everyone, my friend and I created a GitHub Wrapped video for developers to showcase their activity on the platform in a more fun way. The implementation is open-source (https://github.com/rendleyhq/github-wrapped-2024) if you're interested in how it was built. To get a bit geeky, we used masks, keyframe animations, luma key shaders to remove the background from the confetti video, and some other techniques. Also, everything is rendered directly in the browser!! I'm curious to hear your thoughts on the rendering performance, especially if you're running this on your…

Hey HN — I’m Gaurav, one of the founders of Captions. We work on applied AI research for talking videos. Our foundation model, Lipdub, captures how humans speak, and matches full face movement to what’s being said. The model is zero-shot and can generate videos in under a minute, without person-specific training. Building on Lipdub, we’re releasing a few APIs that can generate and translate talking videos in bulk. Here are some ways they could be used: * Translating videos with matching lip movement * Creating personalized videos that include someone’s name or company, like what’s shown in…

The idea: what if you could get a “Masterclass”-style experience, but free, using existing YouTube content? So I made OpenCademy — right now it only has two quick startup "courses" (101 & 102), built from curated YouTube clips, all embedded and organized into modules. It’s still early (no accounts, no backend), but it’s bingeable. Would love thoughts on whether this concept feels useful or just... redundant.
