Photon Empress 🌸I find myself bouncing between Twitter and Mastodon. Not sure one is better than the other.
I will say most of my conversations over here are far more engaging though. Maybe too many bots on Twitter?
Jack Zhang (📹🦝 Raccoon)@PhotonEmpress Honestly, you have to align yourself to whenever there's anger from birdsite to engage at maximum (warp) here. I'm now encountering dead air here.
@JackRacc I mean, when I engage here, regardless of the topic, I seem to get engagement?
@PhotonEmpress I've started to see it die down if it's not a direct engagement. Like a usual post for me is now garnering less attention than when it was in the midst of the migrations.
Olav@PhotonEmpress TBH I'm mostly there for space things anymore. It's.still the best place for nerd things.
@PhotonEmpress
Side note I just saw your new avatar and FANTASTIC

Kat Folland@olavf @PhotonEmpress seconded.
coelliptic@PhotonEmpress @olavf oh my gosh yes!
@olavf it’s a painting that Cariann had done of me for my 45th birthday
@PhotonEmpress way cool.
TimHoyer@PhotonEmpress I'm honestly only on Twitter because of the Tesla and SpaceX stuff. They communicate so well on there. And my friend just quit X today which really sucks
@TimHoyer mind if I ask who your friend was? Maybe I knew them?
@PhotonEmpress Daniel Rodriguez. He was a pipe guy on your recovery ship Megan. Red model Y, I'm gonna miss my huge discount lol. And my tour I didn't get :(
@PhotonEmpress Also, Stennis Livestreams are literally someone paging through a PowerPoint presentation: https://www.youtube.com/watch?v=wzi9pFrP3eY
NASA Stennis Live Stream
@JackRacc hey, compelling live is hard!
@PhotonEmpress I wonder when live broadcast HDR becomes a thing for rocket launches (everything is still Rec. 709 SDR) that might make some people that own some of the newer fandangled mini LED backlit TVs go "WOW those solids are bright."
@PhotonEmpress My friend Paradox Wolf (ctcwired) is planning to broadcast the Anthrocon Dance Competition in 4K 29.97 HDR.
@PhotonEmpress I'm not kidding. This is the kinda stuff that will be in HDR:
@PhotonEmpress Literally not joking when these dance competitions have crews as big as your Starbase T-Mobile announcement.
@JackRacc the problem I gave today is a crappy distribution infrastructure online that scales in 4k/60 HDR. That includes and is especially pointed at YouTube.
@PhotonEmpress Oh don't worry, Paradox is doing tons of A/B testing before deploying at Anthrocon. YT engineers have contacted him about supplying LUTs and how it transforms an HDR source.
Once again, "ctcwired" wherever you can find him.
@JackRacc it’s not the lookup table I take issue with (although that’s not great either) it’s stream stability to the end user. Their SDR down convert isn’t super awesome either, but is usable.
@PhotonEmpress AV1 from a Nvidia NVENC Ada Lovelace GPU instance out to HLS chunks (OBS just started supporting 10bit 4:2:0) on mostly static content might reduce the load, but might require the sender to do both HDR and tonemapped SDR from the source in AV1. Could be something to bring up with the OBS devs. This would mean no transcoding on the 4K streams as all modern browsers support AV1.
@JackRacc I could be mistaken but I think YouTube is 265 10b HDR only for now.
But part 2 here is that for highly available webcasts we use FPGA based encoders. So AV1 realistically out.
But AV1 isn’t part of MPEG so far as I know so I expect it to die like VP7/8/9, VC1, et al. Same story, different song. They never learn.
@PhotonEmpress Don't be so sure about AV1 dying. It's making it into Nvidia Jetson modules as part of the encoding ASIC. It's part of every Ada Lovelace GPU.
It's up to someone to push for YouTube to trial AV1 real time encode direct to HLS chunks using a NVIDIA GPU at the source. I'm certain a bunch of Ada Lovelace Quadros can do the job. NVIDIA's ASIC portion of the GPU is tuned as good as FPGA solutions.
@JackRacc same story, different codec. Just like we still have VC1 and VP9 today I don’t expect AV1 will die. But it won’t be the standard either.
It’s legit the same lesson people seem to need to re-learn over and over and over and over again.
@PhotonEmpress Netflix was a huge proponent of it, now Netflix is getting desperate for funding. Netflix may just go the way of HD DVD soon.
My take though is the decode/encode complexity is favorable vs VVC and will get into low power ASIC chips sooner than VVC. (heck, Nvidia Jetson can go super low in terms of power budget)
Jeremy L Lawson ☕@PhotonEmpress My conversations here have been more engaging as well.
