Concluding
  • Streaming is good technique/platform for
    distributing video art
  • New codecs make HQ (and all video and film
    formats) possible
  • Always save in highest possible quality
    transcode for large scale distribution
  • Challenge is not in coding, hosting, streaming,
    but in DRM for distribution
