I know video streamers cheap out on bandwidth, but 180Mbps is about four times larger than a full fidelity 4k encoding, no?
Also, if anybody else was pushing this bandwidth on Azure it'd bankrupt them. I presume Microsoft are giving themselves an anticompetitive advantage (instead of making their fees fairer).
- jpc0 2y ago2160x3840x8 per frame uncompressed, for 8 bit video... Even at 24fps that exceeds 1 Gbps. So "full fidelity" means ~8:1 compression ratio? At 60 fps it's closer to 4 Gbps so ~20:1? Not to mention 8 bit video is not great and susceptible to banding as well as in general already concidered compressed in color space even when "uncompressed". You can probably get away with streaming it at that quality but by any of my definitions it's not close to high fidelity.
- orra 2y agoSorry, full fidelity was lax terminology. What I really meant using a modern lossy codec (e.g. AV1 or H.265) at a high bitrate, so there is no perceptible loss. I was under the impression 50Mbps was very good, even for 10-bit HDR 4K.
