AVEncoder
Encode H.265 videos perfectly — zero manual tuning needed
What it does
Tired of tweaking CRF, presets, and psy-rd for the best H.265 encode? Adaptive Video Encoder does it for you. It analyzes your video frame by frame — detecting noise, grain, and complexity — then picks the optimal x265 parameters automatically. Drop your file in, get the smallest size with the best quality. Supports HDR10, Dolby Vision, HLG, resolutions up to 8K, and all major formats (MKV, MP4, MOV, AVI, WebM). Linux only. Open source on GitHub.

- ICI compressed 10k PDFs into a 1.4GB video for LLM memory2025 · github.com · ▲61
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…
- VAVidStudio, a browser based video editor that doesn't upload your filesApr 2026 · vidstudio.app · ▲301
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…

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.
