Avidemux Slow Down Video

Slow down or speed up your video to create an amazing post for your social media account: Facebook, Instagram, YouTube or other. The tool is so easy-to-use that you won't encounter any problems even if you don't have any experience in video editing. I have a poorly encoded video of a webcast (I presume it came from a WebEx screencast) and the main issue is that the framerate of the mp4 file is double than it should be. If I play it with VLC and slow down the playback speed to 0.5x, everything's normal and I can understand the audio.
