Hello,

I have a Mac Mini M4 and a new Cinetreak CT-31K camera. I am using NDI tools and OBS. I have a Windows laptop that is feeding two NDI streams (one for lower thirds and one for full screen) that I can see in studio monitor and on OBS. When I connect my camera however, I get a Video Decoder Not Found error in both studio monitor and on OBS. The camera does work on studio monitor on a Windows laptop. What are some troubleshooting steps I can try to make it work with my Mac?

I’ve been asked by some friends to help design their new post house. Actually, downsizing and relocating their current one but a complete rebuild. It’s only a few small edit bays and a color (Resolve) suite, and everything is Mac-based, but they need to support some occasional legacy tape ingest/export. Most of the work they do is UHD but some of it is HDR. They currently use a 3G router but plan to replace it in the move. That means their HDR workflows could avoid quadlink if we go 12G.

The question is should I be doing this as a new 2110 shop, or stick with 12G? The bulk of the routing would be from the edit/color computers into the different suites but the occasional need for tape might complicate things. They also have made some investments in nice BVM monitors and Leader scopes which are all 12G capable, and I assume would need a bridge if we go 2110. My gut says stick with 12G and call it a day.

Is there anything I should check out at NAB next week that might help with this decision?

Hey all, made a post about this on the Tricaster User Group on Facebook but wanted to share it here as well for those who don't have a FB account; normally when updating the Tricaster software, usual recommendation shared by Newtek/Vizrt in the past is to also use the Nvidia driver released just before the Tricaster update was published...

But there's an issue with Nvidia drivers 590 and up that seems to break GPU encoding with old versions of FFMPEG and whatnot and it affects older versions of VMIX as well: https://sd19.vmix.com/knowledgebase/article.aspx/381/hardware-encoder-not-available-or-in-use-error-in-nvidia-drivers-590-or-higher

It causes the stream button in a tricaster session to be blue but have the timecode inside the button (tells you how long you've been streaming) stuck at 00;00 and there are no error logs in the notification window in the top right to tell you that this is an Nvidia GPU related issue when this happens.

after making the post, Kane Peterson (a vizrt employee) responded pretty quickly suggesting to use Nvidia driver 581.42 instead, so I gave that a shot and can confirm RTMP streaming works again when used in combination with 8-5-260302 on a TC-410 Plus!

A few others then responded saying they had the same issue and that fixed it for them, so I figured I'd spread the word to folks here as well, and also because Google tends to show reddit results first these days

Hopes this helps! let me know if you have any questions!

I've been trying to figure out the honest answer to this for a while, because the marketing for both devices is kind of useless for actually deciding.

The spec sheet comparison makes the Extreme look like a no-brainer - more inputs, lower price, portable. But I've talked to a few engineers who used it for a show or two and went back to their ATEM, and I've also talked to people who swapped and never looked back.

From what I can tell the split comes down to one thing: do you need to move the rig? If you're always at a fixed install or you have a cart and a truck, the ATEM is the more predictable choice. Audio sync is more consistent, frame rate handling is cleaner, the software has less of a "we'll fix it in the next update" feel.

But if your workflow involves packing into venues where a cart isn't practical, the Extreme is doing something nothing else really does at that price point. 8 HDMI and 5 NDI in a device you can carry is a real capability gap.

The CPU constraint is real and you have to plan around it - you can't run every feature simultaneously, and NDI sources eat more headroom than HDMI. But that's knowable and plannable, which is different from it being unreliable.

Curious how others in this sub are thinking about it. Is anyone actually running Extreme units in production and if so, what's your source count and use case?

Anyone heading to NAB?

Hi,

I hope this is the right place to ask 🙏. My father bought a 65 inch tv and regrets the purchase because of how large it is. With no return policy I started looking for ways to reduce a 65 inch real estate to 32 inch.

The most accessible way that I could find is a PC with capture card set and forget style. He is not very technical so it's better if the solution is persistent so that I could configure it for him and only maintain it once in a while.

The screen he bought is the LG QNED70A6A. He already have an external android tv which can reduce the screen size to 80% ( 20% less of original size ) . I understand the risks of uneven pixel use but it's better than selling it and getting another one since he might as well regret selling it.

Thank you so much!

hi im a college student 2nd year and im building a neural codecI(better compression than H.264 1.9x smaller than H.264) but decoding requires gpu ,how can this be deployed in webRTC or on mobile/tv devices and devices rely on hardware decoders (H.264 / HEVC / AV1), how my neural codecs to run on cpu or mobiles etc,and current result is 1.9x smaller than H.264 -22–26 dB PSNR.and yes i used ai for coding,please dont hate me.hope i get answers.and also how do i improve my psnr.

Hello everyone,

i‘m thinking about getting a new camera as i have been filming with my Panasonic HC-X929 for more than 10 years now and I want to improve the image quality. I mostly shoot live concerts for a local band. Sometimes, when they record a new Album, i shoot the making of, too. I really like the image of for example an sony fx6, but i am not sure if that would be a good camera for me. The concerts are often in smaller venues with 20-50 people. In terms of lighting, there is only the stage light. The concerts last from 45 minutes to 1 1/2h, so I need a camera that is capable to record continously for that time as a min. I am a bit torn between a Camcorder or a Cinema/hybrid camera. I also have to add that i am a solo operator, so I have to do everything by myself. First i thought, because i am a Solo operator, a camcorder would be perfect, because of the ergonomics, fixed zoom Lens, as i have to cover every angle with one camera, and so on. But I realized that most camcorders don’t have bigger sensors than 1 inch. It makes Sense because of the fixed lens. I am not fixed to a certain brand, but i have to say i do like panasonic, because in these 10+ years my hc-x929 has never let me down once, even in some harsh environments. I guess my only problem is my budget as i only can spend max. 3.000€. One camera that grabbed my attention was the Panasonic DVX-200, because of the 4/3 sensor, but i read that because its an older sensor the low light performance is not that good. I hope i haven‘t forgotten anything and thanks in advance.

I am sorry if I did some grammar mistakes as english is not my native language

I'm hoping this is just a user error, but I am using the latest stable build of Companion on a PC (4.2.6) and when I add some new connections it won't allow me to add up addresses and an error message appears. when I click the connection name I still don't get a page where I can enter any variables, just the error message. I can provide more details tomorrow, but if this sounds familiar to anyone and you have been able to solve it I appreciate the help.

the connections were for BMD hyperdecks, Lumen Visca PTZ.

I delete and select a few times and sometimes it shows up with the ability to add the IP address, but other times I had no luck.

thanks

Can ICND1065s run safely at 7680hz without any issue? Would I better off with a true 7680hz driver ic? Trying to create a cob 1.5 screen 3000x1687.5mm, that can run 1080p @ 120hz @ 8 bit natively?

Recently I bought an old panasonic wv-cl304 security camera and would like to hook it up to my pc to use as a web cam. The problem is that I dont know if the cheaps amazon adapters work like... at all, but I also cant really justify spending over $100 for a dumb idea, even the $50 black magic stuff is kinda high but could suck it up, and ideas for a ok cheap option? Also got an extra cable on it that I dont know what it is.

Has anyone had a go with these and vMix yet?

And in general - how are they? The first Blackmagic with 2022-7, if anyone has any screenshots of the config utility options for this please share.

Hello all, I’ve been experiencing a new issue when trying to output HDMI through my type C dock. All my drivers are up to date, I can still output through my HDMI port so it seems like an issue with either a janky Windows update or something. But yeahhh, anybody else running into an issue like this recently?

Specs:

HP Omen16

RTX 5070 12GB

64GB DDR5 RAM

Intel Ultra9

Hey Everyone.

I’m working on a show and tomorrow we have a press call. There’s a video that’s played during the show that just takes the one cue to start it and then it just plays through. But tomorrow we’re interested in scrubbing through the video (it’s like 12 minutes and we want to scrub to the parts that we need). Is there a way in disguise to play/pause/scrub through the video as needed?

Hey!

I’m embarking on a project that will be hosting gameshows and other in-person shows in a studio. Initially it will only be recorded but in the future this may expand into live streaming.

I am in the process of building out a new PC and want to get a rough idea on whether a high-end laptop or PC is actually required when using a switcher e.g. the ATEM series (and whether that is the setup that is typically recommended for this).

I am leaning towards a PC atm but if I can do without constantly travelling with it (and instead using a cheap laptop) that would be great. Otherwise I presume an M5 Pro/Max MBP would be the way to go if a higher end system is needed on top of a switcher?

Thanks :)

This thread about Artemis coverage led to a lot of internal discussion on our team. We went through the feedback and broke down what people were reacting to vs what is actually possible when streaming from space here https://www.red5.net/blog/live-streaming-from-space-infrastructure-challenges/. There are some real production gaps, but also a lot of misunderstood constraints. Sharing in case anyone wants to go deeper or add their take.
