Building VidTwo: In-Browser 4K Video Downloader & DASH Remuxing Engine

Описание и применение

VidTwo позволяет скачивать 4K/1080p видео из YouTube и Instagram, объединяя отдельные DASH‑потоки видео и аудио в браузере без водяных знаков.

Задача

Most online video downloaders fail at 1080p and 4K because platforms like YouTube separate high‑res video and audio into distinct DASH streams.
