To try out a filter, you just need to select one from the window on the left and it will pop up in the central workspace. To try and make this incredible tool a bit less obtuse, has developed a web interface that lets you play around with FFmpeg’s vast collection of audio and video filters. But with this power comes a considerable degree of complexity, and a learning curve that looks suspiciously like a brick wall. If you’re looking to manipulate video, FFmpeg is one of the most powerful tools out there. ![]() Posted in Software Hacks, Video Hacks Tagged bleep, censoring, ffmpeg Considering that the point of the 1 kHz back-up alarm beep is to draw a person’s attention to a piece of heavy equipment moving about, there is clearly no good reason why the replacement of a naughty word should warrant a similar drawing of attention. This use of silence for censoring naughty words is incidentally becoming more commonplace over an ear-piercing beep, but a tool like Bleep-be-gone can be used to hasten the demise of its terror. Using a Perl-based wrapper, the versatile ffmpeg framework is used to filter a provided video that was afflicted with bleepitus, before outputting a pristine version where the infernal noise is replaced with blissful silence. There is thus a definite argument to be made to censor the censoring beep to preserve one’s sanity, which is the goal of ’s Bleep-be-gone project on GitHub. ![]() Although ostensibly applied to prevent susceptible minds from being exposed to the unspeakable horrors of naughty words, the applied 1 kHz censoring tone is decidedly loud and obnoxious enough that its entertainment level falls somewhere between ‘truck backing up’ and ‘loud claxon in busy traffic’. One of the more interesting cultural phenomena is the ‘bleep’ that replaces certain words in broadcasts, something primarily observed in the US. ![]()
