*. Change save location.
*. Choose the video container format: Original, MPEG4, OGG, WMV (Yikes!), MP3 and Ogg Theora (the official Ogg audio derivative for the video formats).
*. Add audio meta-tags automatically (album, artist, etc).
*. Change between video resolutions (1080p, 720p, 480p, medium or low, etc).
