TIP (translate it, please) is a plugin for VLC media player that helps you to study languages by watching videos.
The plugin allows you to repeat the past few seconds of video but with other audio/subtitle track by pressing just a key. Audio track will be switched back to the previous one at the moment in video where you pressed the key.
You can select the audio and subtitle tracks and period of time for translation in Preferences (in main menu go to Tools > Preferences, switch the Show settings radio button to All and in the left hand menu select Interface > Control interfaces > TIP).
The plugin adds new keyboard shortcuts to VLC:

TIP works with VLC version 3.0.0 or higher.
To install the TIP plugin just copy the libtip_plugin.so file (libtip_plugin.dll for Windows) to the <path-to-vlc>/plugins directory.
