Manually Merge Video and Audio Together

EagleGet now add supports to download hidden formats of online videos such as 1080p HD and 480p. However, the hidden formats usually are single video without audio stream or just single audio. It contains video stream only or audio streams only.

If you want to download these hidden formats of videos, you may need to download the MP4 video and MP4 audio file separately and merge them together to play and enjoy it.

Currently, EagleGet could not merge them automatically. However, you could follow steps below to manually combine them using FFmpeg or MP4Box.

Firstly you should install the latest EagleGet and enable the browser plug-ins correctly.

In your browser, hover your mouse on the video that you want to download and you could find the video download button. Click on the Download button.
