From the developer:
An issue has been discovered which leads to videos being output with excess length. This is due to using a CBR(Constant Bit Rate) encoded mp3. It is solved by using mp3's encoded using VBR(Variable Bit Rate). Sorry for the inconvenience. Thanks for all the donations, keep em coming!
