I just was about buying this great device... and came across the Kiloview E3 with its dual channel encoder and is half the price of the Magewell Ultra Encode AIO... Do you know the E3? If yes, what are your thoughts on it? Thanks Zephan!
@@lbo3534 I would have to take a look at it, but I can’t say I’ve used it before. My encoder can send out a primary and a back up stream and stream to multiple destinations so I’m pretty happy with that.
If I wanted to send 8 hdmi camera feeds from a venue back to a remote studio in a different state. What hardware options are there? Like my ideal is like I have a box in which all the feeds go into it at a venue and then at the studio there is another piece of hardware where all the hdmi feeds can go out that I can send to an atem extreme. Is there anything like this? Is that an encoder like this? Thanks Zephan!
Hey Matthew, I doubt you'd be able to do this with one box at a reasonable price but if you've got a huge piggy bank ready to spend then it's possible. I actually did a video about the "missing" atem a while back that I theorized would be a great way to send multiple live feeds. On the high end, my first thought would be looking into LiveU products because they're very popular in the news/broadcast world. They have a Multi-camera LU810 unit which can do four feeds at a time and they're $18,000 a pop. That's just the transmission unit and you'd still have to receive the signals at the other end. So as you can see it adds up quickly. You're also talking about needing massive amounts of bandwidth to be able to send 8 feeds at a quality that's usable back to a studio. Maybe SRT would be worth a look since it's lower latency. There's a lower end Magewell Ultra Encode SDI that's less than $500 and can encode SRT. You could stack 8 of those in a rack case for $4,000. On the other end in the studio if you have a PC with Vmix, you could receive the SRT signals and then from there do your streaming/switching or output over a Decklink Card. But you're going to run into a lot of issues trying to sync up 8 different feeds because they won't all have identical latency. I asked a colleague who mentioned you’d need something like SRT Miniserver or Haivision gateway to take them in and sync them up. If I were trying to make it a cheap option, I'd try to combine four of the 1080p signals into one 4K signal so at least 4 video feeds transmit simultaneously as one video feed. This way you only need two 4K transmissions.
@@zephanmoses thank you for this in depth response! I currently use Vmix right now for instant replay on a separate machine so for events I split the camera feeds into an instant replay machine and into an Atem and then have two separate scenes in OBS with the Atem and vmix from the separate instant replay machine. (That splitting into the Atem and instant replay makes me want to just have hdmis) However, is it possible with 8 racked encoders (or the 4k one) to send the srt into vmix to both a hypothetical pc with vmix and the other instant replay machine at the same time? I think I’m coming to terms with needing to ditch the Atem and full send with vmix unless there is a way to use them together. Let me know of any product recommendations you have or any affiliate links you may have to these products! Thanks!
@@Speedcubing-TV honestly it sounds like you'd need Vmix to run the whole thing and that you're over-complicating it. You might be able to use a Vmix machine on the event side too for encoding the SRT feed but I'm not as experienced with Vmix so I can't say (I'm mac only).
I recommend reading the manual. In their recording section it explains the estimated time for recording left on the card is based on the streaming bitrate so I’d imagine it’s based on the streaming encoder settings.
Hi Zephan. I would occasionally want to stream 4K and and find it a bit weird this device only support 4k for the HDMI input. Do you have an insight whether 12G SDI might be a firmware update down the line or if the hardware will never support it?
The SDI input is 3G so it’s not 4K capable over SDI. Just curious what are you streaming in 4K and how many of your audience members are actually watching in 4K?
@@zephanmoses well, I haven't actually streamed 4k live yet, but I do 4k edits of conference talks that allow better visibility of embedded slides on a bigger screen, and common wisdom is 4k uploads on yt look better even when watched in HD. I really want to not do edits so a 4k live setup might just occasionally make sense. Example of what I'd hope to achieve for live (by no means perfect, mind you) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-6O1C912O5Yg.html
@@madsastvad I hear you. Most people needing to record/stream in 4K will have a workflow with a 4K switcher, a rack case full of hyperdecks so you can record each individual camera (in 4K) or if Blackmagic or otherwise - record internally in 4K in the camera. That being said, I've also seen tons of people talk about how RU-vid's compression is different at 4K vs HD and so if you drop a 1080p video into a 4K timeline and upload it in 4K you'll still find that it works better because it's not compressed as badly. Basically they use the AVC1 Codec for HD video but they use VP09 for 4K videos. So upon exporting a 4k video (even if it's HD upscaled), upscaling your video will "force" RU-vid to compress your video with the vp09 codec which will look better in the end.
@@zephanmoses that makes a lot of sense, Z. Thanks for that nugget - didn't realise their compression algorithm was different. Also - thanks for your content - it's been super helpful
