To convert a video file, use the "Open File" button.

Beneath the loaded file you can set the options for file converting. In this case, please choose "MP4" as output format.

Furthermore, you can change the bitrate, loudness and much more parameters. Therefore, go to the "Video" and "Audio" tab. Please use simply the default settings here.

Please go to the tab "Filters/Preview" and set the resolution in FullHD (1920 x 1080).

If you are satisfied with the shown preview, please click "Add to queue" on the top menu.

The file will not be converted directly, instead it will be added to the queue. You can inspect the queue by visiting the tab "Queue".

Click "Encode" to convert the video file.
