Questions

(7:33) Q have you tried his new app comms:space

(7:50) Good morning from Portland, OR! (Sorry, gotta take over your pin haha)

(7:55) I tested my new bonding encoder at Hayward Field during the Prefontaine Classic yesterday and it worked great! So happy.

(8:01) Completely full stadium of ~12,000

(13:04) in the supersource you just show, your camera looks very low res. Video playback is sharp.

(13:23) Q: Maybe you should relocate the comments on the map screen to the top, as the bottom get´s blocked by your gallery of devices ;-)

(13:40) I was staying in the dorms haha since wednesday

(13:58) Q I am doing a multi cam live stream in Nanaimo where they race bathtub boat. I bought zowiebox to do SRT stream. Have u tried them. Will i be able to stream via cell service?

(15:41) Q Blackmagic doesn’t support 4K ISO recording, right? How can I stream and simultaneously record all inputs in 4K anyway? Love the Davinci ISO file.

(17:47) SRT is amazingly stable if you give it the max 8 second delay haha

(18:02) SRT is amazingly stable if you give it the max 8 second delay haha

(18:07) HAve you ever considered a pair of leaf springs on the chasis. They make them that small. All that shaking makes me nervous

(18:46) I don’t need live. Just appearance of live. I have 4 boxes 2 for trans and 2 receivers

(19:08) The camera did look low-res in that supersouce. Video was sharp.

(19:57) Maybe that was because of your memory issue, now gone

(19:58) now it´s high res again

(20:17) Q: Seems, that your Key for OBS isn´t 100% correct. When you quit OBS, frame get´s brighter. When you engaged OBS again, frame got darker.

(21:49) When you first cut to it, it was low-res. Now it looks normal. Maybe an encoding problem

(22:07) Yes, color is washed out on AP's entire program output.

(22:14) didn´t you say, your had your camera open in chrome? It was a very unusual issue, the rest of the frame was sharp.

(23:17) Wow! I have noticed that Black/Almost Black thing with ATEM/OBS/DecLink and just decided to WHY ASK WHY

(24:03) hello from Larnaca, Cyprus

(25:57) Top and side handles in CAGE mode

(26:44) Is the printing on the bars printing or etching?

(27:22) The bar printing is fiber laser 🙂

(27:27) but it could have just as well been UV printing

(28:19) it feels raised but it is in fact removing 0.1mm of black anodized material

(29:35) Flashback to the 10 hour cart build..

(30:05) We dont normally do White but ... 🙂

(31:00) insert nuts first?

(31:35) the slide in are for tTOP handle

(34:16) please use WASHERS 🙂

(38:00) @INUX3D Manufacturing Are you doing the fiber laser branding on all your products or is this a one off for Aaron

(38:14) Now we dont have to do an assembly video! Thanks Aaron 🙂

(39:46) Makes the chunky boy Yolobox even chunkier

(39:59) We do ALL products branding now

(40:30) Q: Any tips for connecting Micro BNC/DIN 1.0/2.3? We just got a VideoAssist 5", but I can't get any cables to work and I don't want to break the connector if I'm doing it wrong

(40:49) @Aidan Comi if you're having trouble with 3rd party, BMD sells a micro BNC to BNC cable that presumably would work?

(41:09) Q: how many ports does yolobox extreme Holy moly

(42:16) Q Can you get a Decklink card or Ultrastudio to output a specific color when there is no signal?

(44:13) Q click save?

(44:17) Q: does FoMaKo PTZ camera system work with blackmagic design switchers?

(46:13) We have the same ptz and use visca. With the control panel and a constellation and it works great

(46:55) advanced panels have a joystick

(46:57) Yes both work

(47:01) When I first noticed it I thought the almost black thing was something I introduced with my HDMI matrix, but seeing it on your OBS/ATEM/Decklink is enlightening

(47:18) Q i ask b/c we use a PC monitor out for chroma key overlay. That monitor's desktop BG is green in case the presentation app crashes. Custom BG spanning all monitors so they all have the correct looks.

(47:34) Have you tried with other software other then OBS?

(48:00) If we upgrade to an SDI atem, we will likely need a decklink

(49:02) Q: I googled and looks like ATEM Switchers update 9.6.2 added support for VISCA over IP on all Constellations in 2024

(49:20) Q: How is the electrical permitting going?

(54:16) Oh man... I do not have the guts to play with high voltage

(54:31) Wow so you lost the Thunderbolt box for the ZoomISO right before the show? Oh no.

(55:16) use FoMaKo PTZ system(with its controller), connect the ptz cameras to blackmagic design via SDI. it's this possible?

(56:47) I didn't try my setup before live streaming the other day and my camera was busted. Always test your gear!

(56:56) Q What do you think using a Wavlink Dual 4k instead a Decklink for key fill?

(1:01:23) @Aaron Parecki I think you need to get to the H2R home window. Maybe it's closed.

(1:03:04) @Aaron Parecki uncheck Pre Multiplied Key and use those values: Clip 45% and Gain 15%

(1:03:16) And you blow two inputs on the ATEM

(1:08:01) Q: I want to be able to run two wireless networks in two different locations. One in a venue and one in our production trailer. I’ve tried running two gi-lnets and it never works. Is there a solution?

(1:08:35) @Clear Life Media I assume you're trying to have two Access Points with the same LAN network?

(1:08:45) @grzegorz yeah. I have one in the venue. But our trailer has trouble getting cell service cause it’s a big metal trailer. But having wireless in the trailer as well would be awesome.

(1:08:50) Tried even a different router and still the same issue where it’s not recognizing the “internet” connection

(1:08:58) @Clear Life Media I think you want APs, not full on routers, but I don't remember whether gl.inet routers have pure AP mode, without NAT

(1:09:03) For some reason in router mode with 2 connected the one in router mode still doesn’t go “online” and you lose control over the router so I can’t even see what’s happening on it.

(1:09:20) The issue with the venue wireless is we go to a bunch of random ones. So it’s nice that the team can use our own wireless networks and passwords. If that makes sense

(1:09:30) I can take it to discord and ask this week

(1:10:50) Same network. But have an access point in both spots

(1:11:48) Always use key and fill if possible. It may seem harder but will actually be easier in the long run

(1:12:33) Q: is there a usb-c dongle you suggest for an iPad for mixeffect to get usb-c and Ethernet in. Magewell is sending me their new ip to usb to test.

(1:13:54) @TVJAY I also use key and fill in ATEM but unchecking pre multiplied key and with those values i never had a problem

(1:21:44) It is partly cloudy on the ATEM today

(1:21:52) Q: I can make an image that works with premultiplied key, why can’t I do premultiplied video over a single ATEM input?

(1:22:35) Q: No background & picture on comments after messing with settings

(1:23:31) SDI only carries luma and chroma, and key is "alpha" channel equivalent

(1:24:00) Q: Hi, my company is setting up a podcasting studio. Which cameras would you recommend to pair with a Rodecaster Video?

(1:27:17) there is something about phones that is fun

(1:28:27) Q: What are you using for the telephony card?

(1:30:09) What door intercom are you using?

(1:31:02) My building has had a lot of issues with doorbird

(1:31:20) Tie an AI Agent to it and it would be fun

(1:31:28) my new Grandstream router has a PBX built in but I haven't played with it. Actually that should be my next stream

(1:32:19) Intercom goes down every x amount of time, takes like 30 seconds to buzz my phone, door buzzer fails now and then. stuff like that
