Dear NANOG members,
Hoping that some members working at Google/YouTube might be part of this
group, I respectfully suggest adding or noting the following to
YouTube's bandwidth requirements page [1]:
* *8K (H.264):* 110 Mbps
* *8K (H.265):* 60 Mbps
[1] https://support.google.com/youtube/answer/78358?hl=en
*References and Standards:*
* *ITU-T H.265 (HEVC) Standard:* High Efficiency Video Coding (HEVC)
significantly reduces bit rate requirements compared to H.264 while
maintaining the same video quality. (Source
<https://en.wikipedia.org/wiki/High_Efficiency_Video_Coding>)
* *Bitrate Requirements for 8K Video:*
o A study on *8K 120Hz HEVC/H.265 encoding* indicates that the
required bit rate ranges from *85–110 Mbps*. (Source
<https://www.cambridge.org/core/journals/apsipa-transactions-on-signal-and-information-processing/article/video-bitrate-requirements-for-8k-120hz-hevch265-temporal-scalable-coding-experimental-study-based-on-8k-subjective-evaluations/ED85B79ECC1EC55D74B1EB4FB7F39B46>)
o *H.264 encoding* generally requires higher bit rates for high
resolutions, and an estimated bit rate for 8K content is around
*110 Mbps*.
o *H.265 (HEVC) encoding* allows for more efficient compression,
reducing the required bitrate for *8K content to approximately
60 Mbps* while maintaining similar video quality.
*Conclusion:*
To improve the accuracy of YouTube's bandwidth requirement
documentation, I propose updating the page with recommended bitrates for
*8K (H.264) and 8K (H.265) video formats*. This would provide more
precise information to users regarding bandwidth needs for
high-resolution content delivery.
Best Regards and wishes, Sincerely,
Mr. Volkan SALiH
