1. Lossy H.264 video and AAC audio compression demo (using FFmpeg)


    from Ryan Edge Added 6 0 0

    Gradual degradation of video and audio quality as bit rate is reduced in 15 second intervals, demonstrated using H.264 and AAC codecs via FFmpeg. To view the data rates, TURN ON CLOSED CAPTIONING. Bit rates are displayed in the lower half of the frame. Note the video begins at 318 Kbps constant. This is rather low in the first place, but illustrates the quick quality loss. Jump around to get a better idea of what's being thrown away... 00:00:30 | 00:01:30 | 00:02:30 | 00:03:30 | 00:04:30 FFmpeg command example: ffmpeg -i input1.mp4 -c:v libx264 -crf 20 -c:a aac -strict -2 -b:a 96k output.mp4 Encode/H.264: https://trac.ffmpeg.org/wiki/Encode/H... Encode/AAC: https://trac.ffmpeg.org/wiki/Encode/AAC Video for Sinéad O'Connor's "Nothing Compares 2 U" is presented/altered here for educational purposes. And is pretty transformative, in my opinion.

              • Powerhouse 10-Year Anniversary Mural


                from Powerhouse Factories Added 9 0 0

                Ten years ago, we were hanging our art on any city street that we could find. Sometimes we asked permission, sometimes we didn’t. Back then all we cared about was about staying up, or getting our art out into the world for others to see. We hoped that people would see the art and engage with it—tear it, paint on it, add to it. Now a decade later, we set out to create one of our largest installs to date. To celebrate Powerhouse's 10-year anniversary, we wanted to create something that told the story of our evolution as Powerhouse and showcased our history of partnering with local arts and music organizations to share our passion for design, screen printing and rock posters. Thanks go to the Art Academy of Cincinnati for graciously providing the real estate to create our piece.

                  • Savannah sets her own curriculum


                    from Inclusive Solutions Added 12 0 0

                    When I am faced with parents or educators who seem sceptical that their children or students may actually have more to say than just “yes” or “no”; I am undaunted. I too never believed that Savannah would ever be able to communicate more than just making requests. The first time I was challenged on this issue, was when I attended an AAC course by Dr. Margi Lilienfeld sometime in 2004/2005. She spoke about “presuming competence”. I believed that Savannah was capable of more than she could show at that time, but I felt that all these symbols were too much for her. How wrong I was!
