Many users want to download YouTube videos in 4K quality—but often face a frustrating problem.

The downloaded file plays video only, with no sound.

ONCCG solves this by processing and merging audio and video streams before download.

Why 4K Downloads Sometimes Have No Audio

YouTube stores high-resolution video and audio in separate streams for efficiency.

Many downloaders only fetch the video stream, which produces a silent file.

ONCCG automatically combines both streams into one playable video with sound.
