+## Interesting Use Cases
+
+### dub alignment
+
+describealign is robust enough to align media with completely different dialogue, meaning it can align audio dubbed in a different language to the original video.
+
+### lossless video editing
+
+With default settings (i.e. --stretch_audio set to False), describealign doesn't re-encode either the video or audio streams. It aligns them by modifying the timestamps that video frames are shown at, which means no loss in quality. Basic video editing can be done by deleting or stretching segments of a video's sound in Audacity, then running describealign on the original video and the modified audio with --smoothness set low (e.g. 1). The video will be edited losslessly, but the audio can also be edited losslessly by exporting from Audacity as FLAC, then setting --extension to mkv or another container that supports FLAC.
