 name:           cut-the-crap
-version:        1.4.0
+version:        1.4.1
 synopsis:       Cuts out uninteresting parts of videos by detecting silences.
 description:    Cut the crap is an automatic video editing program for streamers. It can cut out uninteresting parts by detecting silences. This was inspired by [jumpcutter](https://github.com/carykh/jumpcutter), where this program can get better quality results by using an (optional) dedicated microphone track. This prevents cutting of [quieter consonants](https://youtu.be/DQ8orIurGxw?t=675) for example. Using ffmpeg more efficiently also produces faster results and is less error prone.
