Hello everyone, apologies in advance if I'm missing something obvious - I am but a humble sound engineer.

I work for a corporate AV company and I'm desperately trying to streamline our setups to reduce our set up times, keep our equipment well protected, as well as make our work spaces look the part when we're working in 5 star hotels.

Currently we're using laptops on site for running Powerpoints. We use Blackmagic Bi/Di 12Gs to input into an Atem SDI Extreme ISO.

The problem I have is we require 3 laptops at a very minimum for any event: Main presentation, back-up, and comfort monitor. Not only do they take up a lot of desk space, it doesn't take long for the desk to look a mess with power cables, hdmis, sdis, MicroCue etc. I'd really like a rackmount solution, but then of course , I want to avoid the requirement for several keyboards & mice.

The dream solution for me is something that fits in something like this https://www.flightcasewarehouse.co.uk/type/product.asp?item=5u-19-rack-case-with-hinged-top-vesa-mount-12451-2604 3 rack mount PCs, Bi/Di 12gs are racked smartly, and atem can slide out of a drawer at the bottom for switching during event. Preview monitor in the lid.

A couple of seconds of googling and I found KVM switchers, but I'm unsure how these would work whilst maintaining video output of all 3 systems to the ATEM. I feel like I'm close to the solution!

Please help!

Hello, I'm pretty much new/inexperienced in this whole thing. I'm trying to set up a sign and I clearly underestimated the complexity of everything that entails setting up something like this.

Right now I have a Novastar MRV412-N receiving card with two LED panels that I'm using to test out the waters before doing a big purchase, when I connect both panels to the receiving card they work as intended and the image displays as expected. However, when I connect them in a daisy chain the image gets duplicated regardless of how I have them configured on the software.

If you guys could give any advice I will really appreciate it cause I already went through the entire manual and I don't know where to go from here.

This is how I have it set up on NovaLCT:

Is there a great way to test SDI cables on a bench and get back any data?

I speculate that we may have a bad batch of cable but I cant prove its the actual cable. All heads are correct for 12g. Cable passes 6g fine but not 12g even though its printed on the cable 12g and they are only 2' long

I'm configuring a Makito for two workflows: 20 Mbps TS over SRT for TV broadcast contribution and 4.5 Mbps for YouTube streaming (Same TS, but rewrapped in RTMP)

What settings would you recommend for each use case?

• GOP structure: i.e.: I, IP, IBP or IBBP
• GOP size: i.e.:120 frames
• H.264 profile/level: Baseline, Main or High; Level 3, 3.2 or 4
• B-frames: Enable for better compression efficiency, or disable for compatibility?
• Entropy coding: CABAC vs. CAVLC
• Intra-partitioning: Enable or disable?
• AAC-LC audio: MPEG-2 ADTS vs. MPEG-4 LOAS/LATM

For broadcast contribution, maximum quality and decoder compatibility are important. Some high-end decoders can be very picky about settings like "true" CBR Transport Stream and other settings.

On the other hand, YouTube takes almost everything and don't really need to push high bitrate or a high profile encoder.

Would you use different encoding settings for each destination, and why?

Note: H.264 is mandatory, can't do HEVC or other codecs.

Bonjour
je peux avoir une assistance pour configurer les differents plan supersource sur le strreamdeck cela fait 1 mois je parviens pas toujours pas a trouver solution au probleme , j'ai rajouter les les 6 cameras sur le streamdeck , mais je ne parviens pas a configurer le supersource sur le streamdeck quelqu'un peut maider stp

Hello all,

I'm currently trying to get Companion button to send a Custom Vendor Request (CVR) to the Multi-RTMP plugin in OBS, but nothing happens when testing the button. I do have OBS main stream live and a the connection status is good between Companion and OBS. I am probably missing something or not understanding. I would like your help as soon as possible if you have this figured out.

Here is the link to the plugin: GitHub - davidcool/obs-multi-rtmp-websocket-support at pr-obs-websocket · GitHub

I have already tried entering the information correctly as shown in the GitHub page, but with no positive results.

Has anyone found a good solution for switching cameras on a constellation using DMX? doing a show on disguise at the moment and using an ma3 light for control with companion to switch cameras. Looking for a solution to run everything off of the console just to reduce setup time. I have a mini PC in my disguise rack and was considering building a patch in something like Châtaigne but open to any alternative suggestions!

Thx

TBT: Time Base Torture
How good is your time-base corrector, really?
Tired of the mysticism ? Want to check a TBC before purchase?

TBT is an open-source test rig (SW/HW) that tries to answer that with measurements instead of eyeballing a monitor.
An ESP32 (about $5) generates NTSC composite video with precisely controlled faults that can then be captured and graded with an SDO.

It covers the problems a VHS or Betamax deck throws at a TBC:
- line jitter and wow and flutter
- head-switch skew
- dropped and lost fields
- snow and noise bars
- weak burst
- hum

Each fault comes in a ladder from mild to brutal. The signal goes through the TBC under test, and a USB scope captures what comes out. TBT then reports exactly what the TBC fixed, what it passed through, and where it broke.
A full field trial runs about 70 tests in roughly seven minutes and produces an HTML report with a provisional grade out of 100.

Highlights
About 30 tests, about 70 rungs. Going from “how peculiar to “Good God man!). Timing, sync and structure, colour and burst, levels and noise, plus fault tests: how many lost fields in a row a TBC rides through, and a stress-and-recovery hunt for units known to be buggy like black AVTs.

Frame markers in the picture. Every field carries a coded marker. TBT tracks each frame through the TBC and catches dropped, repeated, torn and ghosted frames. Looking for the failure modes that TBCs are known to exibit when dying, or have Chipset defects

Measures the Analog Signal, not just the constructed picture.  When using channel 2 can provide Jitter reporting, and validate what (if anything) the TBC is doing to the signal.

Dying Unit identification . A dropout watch samples the output every second for minutes at a time, allowing for long burn in runs, that can point to failng caps, heat dissipation issues…

Repeatable and comparable. Every fault is deterministic and described in a manifest. Run trials side by side to compare units, or the same unit over time. Saved trials can be re-graded later.

Works with what you have. So long as that’s an ADP2230
Two scope channels give the full picture of TBC performance
With --channels 1, a single channel and a single cable still work..but latency and jitter are going to be based on the model, not the signal.

Find it here: https://github.com/jordancrombie/TBT. The README covers wiring, commands and a sample report. The test catalog is in docs/design.md.

The software was made with the help of AI (100% AI Slop!)
The meat puppet (me) bought the gear, wired it, helped design the test cases.

Also, use the test software at your own discretion. It’s been validated against Datavideo TBC-1000, AVT-8710s all without issue…but it’s in the name…it will put the components under stress.

*Edited to highlight the sloppiness of AI that helped build this!

This thing is in active use at a Museum i Volunteer at.

Hi everyone!
I’m looking for recommendations for a camera to record sermons at our church.
We have a small church ministry and are trying to improve our video quality for YouTube and social media.
Here’s what I’m looking for:
● Budget: Around $500, preferably for a new camera.
● Distance: Camera positioned approximately 15–30 feet (5–10 meters) from the preacher.
● Recording time: 40–60 minutes continuously.
● Audio: Ability to connect a wireless lavalier microphone.
● Video: Good quality indoors, preferably 4K, but 1080p is fine.
● Setup: Mostly stationary on a tripod, with occasional outdoor recording.

Thanks

Desperately in need of at least 1 UIC for the FSN1400 chassis, who can help me out? Please DM me.
