There is no malware or difference in the exe version(as the same python version is converted to. You can either use the python based version for viewing logs and changing source code if you want, but if you are looking for faster renders then download the executable version of Datamosher Pro from the release page( ) With Datamosher Pro, you can quickly and easily datamosh your videos(supports mp4, gif, avi, etc). It contains 7 different effects and more will be added in future, you can also help to make new effects. I was also looking for good datamoshing softwares, you can either have to use those old softwares like Avidemux or have to look for some paid plugins, but I created my own GUI based application that is Datamosher Pro which is a free project. Datamoshing is an effect that really looks cool and if you also want to make this glitch effect with your videos, you are in the right place!
