Video coding

• More pixels = more information

• Quality = attention (+ recall )

Premise: HQ pays off

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
