I found this app to do what is says: Powerful & fast removal of sound in videos. This was done well with progress bars of each file in the batched conversion and highlighting the one video that it was unable to convert.However, some basic user interface (UI) items/functionality were missing that lowered my rating.- Settings: missing a setting to set a default starting directory for source files and exported file location for completed files. Thus requiring one to manually change these locations at the start of each conversion.- Exported file location: always starts by creating a SilentVideos folder in the directory you choose. If one exists it will ask to overwrite and proceed. This should have an option to continually add videos to the export folder.- Drag and drop: The main window says drag and drop, but it only works for one file. If you want to drag multiple files, one needs to open a dialog box with the Add Files button- Buttons: Two tiny buttons (About & Settings) on top right have overwriting labels and icons- Spelling error: Chose instead of Choose
