Encode H.265 videos perfectly — zero manual tuning needed

While building a Retrieval-Augmented Generation (RAG) system, I was frustrated by my vector database consuming 8GB RAM just to search my own PDFs. After incurring $150 in cloud costs, I had an unconventional idea: what if I encoded my documents into video frames? The concept sounded absurd—storing text in video? But modern video codecs have been optimized for compression over decades. So, I converted text into QR codes, then encoded those as video frames, letting H.264/H.265 handle the compression. The results were surprising. 10,000 PDFs compressed down to a 1.4GB video file. Search…

Hi HN, I built VidStudio, a privacy focused video editor that runs in the browser. I tried to keep it as frictionless as possible, so there are no accounts and no uploads. Everything is persisted on your machine. Some of the features: multi-track timeline, frame accurate seek, MP4 export, audio, video, image, and text tracks, and a WebGL backed canvas where available. It also works on mobile. Under the hood, WebCodecs handles frame decode for timeline playback and scrubbing, which is what makes seeking responsive since decode runs on the hardware decoder when the browser supports it. FFmpeg…

I built an experiment that uses an overfitted transformer and arithmetic coding to compress individual files. Instead of training the model to generalize, I train a 900KB transformer to memorize a single file and predict the next byte. Those predictions are fed into an arithmetic coder to produce the compressed output. On a 100MB NYC taxi CSV, it compresses to about 7MB (~0.5 bits/byte). On a 100MB slice of enwik9, it compresses to about 21MB (~1.68 bits/byte). It's pretty slow right now (roughly 20–30 minutes of training and 45 minutes each for compression and decompression on my…

Hi HN, this is a project I've been working on as part of my PhD. Vidformer is a system that makes video annotation or transformation scripts practically instant. Traditional scripts that render full videos can take minutes—Vidformer speeds this up by optimizing execution and using on-demand rendering, so results appear immediately instead of waiting for entire videos to render. It works as a drop-in replacement for OpenCV's cv2, meaning most scripts can adopt it by simply changing "import cv2" to "import vidformer.cv2 as cv2"—no need to rewrite code or sacrifice flexibility. Vidformer is…

Hi! This is a quick lil CLI I've created for upscaling videos using Apple's MetalFX (https://developer.apple.com/documentation/metalfx). There are a few improvements I plan to make, such as HDR support and a progress bar, but if it sounds interesting, please give it a try and let me know what you think!

Hello HN! I would like to show our recent research project: DynamiCrafter. DynamiCrafter can animate open-domain still images based on text prompt by leveraging the pre-trained video diffusion priors. It supports: - Image-to-video generation - Storytelling video generation - Looping video generation - Generative frame interpolation We have released source code at https://github.com/Doubiiu/DynamiCrafter and deployed a demo at https://huggingface.co/spaces/Doubiiu/DynamiCrafter Please also refer to…

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…

It's our new text-to-image model: a 9.3B single-stream diffusion transformer trained entirely from scratch. We focused heavily on controllability through structured JSON prompts, with strong text rendering, spatial awareness through bounding box guidance, and color palette control. It has the best text rendering of any open-weight model we've tested so far, and the NF4 quantized checkpoint runs on a single 24GB GPU. For more technical details and examples see our blog post: https://ideogram.ai/blog/ideogram-4.0/ We will be happy to answer any questions :)

FFmpeg converts everything except subtitles across format boundaries. SRT to Blu-ray PGS? "Subtitle encoding currently only possible from text to text or bitmap to bitmap." Ticket #3819, filed 2014. I built this with Claude Code over a few weeks. Claude wrote most of the encoder, found an integer overflow in the decoder buffer tracking, and ran review from five angles. I read the Panasonic and Sony patents, made the architectural calls, and told it when it was wrong about the spec. We argued about whether DTS computation belongs in the muxer. (It does, and also in fftools. We did both.)…
