The question, then, is how to create these 100 poster images without too much work. We also support this on UiO’s web pages, which serves as the long-term archive of the material. However, given that we are talking about approximately 100 video files, I am sure there would have been some hiccups.Ī quicker and better option is to add “poster images” when uploading the files to YouTube. This could probably be done with FFmpeg without recompressing the files. One solution could be to add some frames at the beginning of each video file. This would then also serve as the “thumbnail” of the video when presented in a grid format. So, to create some consistency among the videos, we decided to make an introduction slide for each of them. People have sent us their videos in advance, but they all have different first “slides”. Presentations have been pre-recorded (10 minutes each) and we also have short poster blitz videos (1 minute each).

Like many other conferences these days, this one will also be run online. We are organizing the Rhythm Production and Perception Workshop 2021 at RITMO a week from now.
