What They Say
Netflix published a blog post to say that it is to use its latest codec schemes including per-title encode optimisations and per-shot dynamic optimisation on its back catalogue to reduce the bitrate needed without losing quality. The services started with fixed bitrate encoding. The firm has been improving its codec optimisation and can also reduce the bitrate by less, but with higher quality. On average, the firm said that it needs 50% less bitrate to achieve the same quality. The catalogue upgrade will start with UltraHD titles and then be extended to HDR.
What We Think
Encoding and decoding of codecs are very different. Decoding is a matter of precisely implementing the standard, while encoding usually develops for quite some time after a new codec is introduced as more knowledge on how to use different settings are used. (BR)
