Web Video editor, 100% local, AI subtitle, auto cut based on volume
I made this mostly to make content creation faster. When recording a youtube video/ podcast. there's alot of downtime (silence) while looking at scripts or getting the correct item to display. So I made a webapp to automatically cut and stich the video back together then I can further edit in davinci resolve. But I recently found out that this is crazy good for rewatching lectures or meeting recordings, No need to render, just drop the video in and watch it right away. 30min lecture can be watched in 12min! I even added auto generation of subtitles to make studying lecture /meeting…

In plain words
Web Video Editor is a local web application that automatically removes silence and dead air from videos, then stitches them back together. It generates AI subtitles and requires no rendering—users can upload footage and watch the edited result immediately. Originally built for content creators editing YouTube videos and podcasts, it also works well for condensing lectures and meeting recordings, potentially reducing watch time by half. All processing, including AI subtitle generation, runs locally on the user's device.

FastCut2023 · fastcutai.co · ▲363Hi HN, We're two final-year college students from India, and we just launched FastCut – an AI tool to help creators, coaches, and marketers quickly edit there short form content (Reels, Shorts, TikToks) to make it more engaging. The goal is simple: Let users upload a raw video and get back a polished, engaging short in minutes — without touching a timeline. FastCut does the following: Automatically trims silences and filler content - Adds clean, animated captions using speech-to-text - Enhances audio - Pulls in relevant images (via Google Search), stock clips, stickers, and GIFs - Adds…
Edit videos faster by automatically removing silences2022 · kapwing.com · ▲171Our team is filled with technologists and creators, and when we record and edit videos, 80% of the time is spent chopping up the video, removing silences, and picking the right takes. So we decided to build a tool that did that for you — or at least get you there most of the way! Our initial implementation is somewhat naïve and uses a user configurable silence threshold that just reads in volume levels. In the future, we’d like to use a frequency-based approach that focuses on the human voice. We’re also open to ideas, so let us know if you have any!

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
