As you may have already seen, we have now uploaded a lot of NIME 2011 videos to Vimeo. Most of the presentations are already there (including keynotes), and about half of the performances. The rest will appear in not too long (there is a lot of gigabytes to edit, process and upload).
We have had a couple of reports about audio disappearing after a while in some of the videos being streamed from Vimeo. There is no problem if you choose to download the files and play them from your hard drive. We are trying figure out what exactly the problem is, and have had success with reuploading files to Vimeo. Please let us know if there are problems with any of the files you want to see, and we will try to fix them as soon as possible.
