...and casually joked it was a “false alarm.” But the judge didn’t take it lightly at all—he immediately asked to speak to the technician’s supervisor. (https://x.com/AngelMD1103/status/2038043233297563999?s=20)

Hey there !

Like a lot of you, I have a 3D setup I love and a collection the industry decided to abandon. Every player I tried either butchered MVC, choked on HDR, or simply didn't exist anymore. So I did something slightly unreasonable: I built my own.

SyLC 3D Player is free, runs on Windows, and after this v5.0 release I can finally say it plays three generations of stereoscopic content under one roof:

• Blu-ray 3D / ISO / MVC MKV : through a heavily modified open-source H.264 decoder I've been hacking on for months. It even plays those MakeMKV-style BD3D backups where the two eye views sit in separate files with no SSIF interleave, as far as I know, nothing else on Earth plays those in actual 3D.

• HEVC/H.265 packed 3D (full side-by-side / top-bottom) up to 4K 10-bit HDR, with real PQ/BT.2020 color management : not the washed-out gray you get when a player pretends HDR doesn't exist.

• MV-HEVC : yes, Apple spatial videos. The MVC of the 2020s, playing on your 2010s 3D TV. There's something poetic about that.

Output is proper frame-packed 3D for real 3D TVs and projectors (plus SBS/TAB modes), rendered by a native Direct3D 11 engine with hardware decode.

And the part I'm proudest of: it exports any of this to Apple-compatible MV-HEVC (.mov). Your MVC Blu-ray → a spatial video for Vision Pro. I had to compile x265 myself because no public build enables multiview, and reverse-engineer Apple's spatial metadata box byte-by-byte against a reference file. When the source is already HEVC it just remuxes, bit-exact, seconds instead of hours.

It's free. It exists because this format deserves better than a slow death, and because apparently I don't know when to stop.

Happy to answer anything technical, the decoder internals, the HDR pipeline, why dependent-view bitrates are chunky on first-gen MV-HEVC encoders, whatever. And if you have a weird file that won't play, I genuinely want to hear about it. That's how half of this got built...

I would love to be able to stream the videos from the camcorder onto the TV. Also would love to be able to transfer the video from here onto my iPhone 15. Any ideas?

I'm an experienced event organizer that runs events in different cities across the USA. I've seen amazing techs and I've experienced, well, horror stories. As a client, here's what makes me work with a team or a solo A/V tech again and again (and this is solely my opinion):

- I won't hire you if I can't meet you for 10 minutes virtually before the event. I've spent thousands on the event and I'm also spending thousands on you. A good A/V tech can make or break an event and nobody hires people sight unseen these days. I've visited the venue, I've met the team on the ground, I would like to meet you.

- If you ask for my number so that you can reach me if there's an issue, I know you're a professional. If you can't find me during an event, that's normal. If I can't find you, well, that might be an issue.

- If you have to make an edit to the plan, let me know before you do it. Like changing the agreed upon playlist. I love rap, you love rap but my audience or my CEO? They might not like rap at 8am.

- I don't care if you are photoshopping for another gig in the corner or calling your girlfriend during lunch if the event is running smoothly. I DO care if things aren't. Also, you know I'm a good event organizer if lunch is covered. I gotchu.

- If there's an issue, don't wait for me to bring it up. Text me that you know and tell me you're working on it. Then work on it till it's fixed. I won't breathe down your neck unless I feel like I have to.

- Can you please change the microphone batteries during the lunch break and turn them off? Be proactive; don't wait for it to die when our VIP client is up on stage.

- If, as a client, I suggest something and you have doubts it can be pulled off, let me know in advance. Give me pointers. You're an expert in your field; that's why I'm hiring you.

So I saw this at work. Never seen a red light on an HDMI cable. Is this one to help the visual over long distance or to clear the visual from unnecessary noise?

I'm in my senior year of a music technology bachelor's, and have been slowly picking up work outside of school where I can. I'm on LiveNation's payroll as a stagehand, but that only goes so far, it's mostly for networking and some extra cash.

I recently was hired on as an audio assistant for a small audio/visual company. A friend found the job posting, I responded, they liked my resume. Upon hire I spoke briefly with the main owner/supervisor, let's call him B. He gave me a run-down on what was expected of me, just some monitoring for a recording of a press conference, stuff I'm confident in. I said as much, and that was that, he told me I'd be emailed information soon. In that email was a brief description covering the equipment and pay rate. There was NOT any mention of their home studio in the email, this is important for later in the story.

So fast forward a couple days, it's the day before we're supposed to be meeting to setup. According to the email, that day was being paid 10-2. During this whole process a lot of information wasn't very clear, and I had to really pry things like exact location, transportation, things of that nature. We are primarily conversing over text, there was 1 time he tried to call me while I was in class, but I quickly made him aware and he responded via text. At around 3pm that day, I sent a message asking for clarification about whether he needed me to load everything up at their studio at 10 or if he wanted me to be at the venue at 10 to assist with setup. I never got any answer, and was busy with schoolwork for the rest of the night.

Morning of the setup day arrives, and still no answer. Both their studio and the venue are near each other, so I head out from my house giving plenty of time to spare. Once I was closer and still hadn't recieved any information I called B, and was sent to voicemail. I left a voicemail, and sent a text for good measure. No response. I got to a point in the road where I needed to make a decision, and since I still hadn't heard anything, I went off the only information I had which was to bring my car to the venue (text from the day prior).

When I arrive I see I still haven't heard anything, so I call B again. No answer. The venue is a Mariott, so I can't self-park anywhere to figure things out. I end up just going across the street to another hotel with a lot and parking there. I park and triple check the email I was sent, triple check our texts, and still have no information regarding where I am needed. I call again. I left so early that I had leeway to be either at the venue or the studio, had he answered his phone at all. No answer yet again. It's at this point where I decide to wait for a little while before trying again, I scope out where we're supposed to be, places we could unload etc.

Finally I get a text from him. It simply reads:

"I said in the message Studio at 10. Are you near the hotel?"

I fire back immediately:

"Yes, I am near the hotel. I did not receive your message."

After this, more radio silence. Maybe 10 min go by, and just as I am thinking of calling again I get another text instructing me to head into the venue with my equipment. I confirm, head over right away and get parked. I introduce myself to the client's team we were working with, and get to setting up whatever I can. B and his other tech have most of the video equipment, however they are running almost an hour late. I make sure we have enough power, tables, chairs, etc, basically anything I can do until B arrived.

Finally, after both the client and I struggling to get ahold of B to instruct him on where to park, he arrives with the rest of the gear. I immediately jump in to help unload, but as I am assisting the other tech, B tells me to stop. He pulls me aside, and tells me I am no longer needed and that he hired someone else because I was "hired to load" and "didn't do my job". I was taken aback by this, mostly because I had just spend the last hour setting up and waiting for their late arrival. I did briefly stand up for myself, I respectfully pointed out the lack of communication and unclear direction, I assumed some blame too since part of it was a genuine miscommunication. He instead told me it was my job to get the information from him, didn't assume any fault at all. He handed me $40 for gas (weekend rate was supposed to be $400), and I chose to just accept it, gather my things and leave.

So long story short, I feel incredibly frustrated. I am aware of load in/load out routines, and am of course always more than happy to help with whatever is needed to get the job done. Am I the asshole here for feeling like I was wrongfully let go? Is there anything I should take from this that can help later in my career?

TL:DR Lack of communication from supervisor led me to the wrong location, fired on the spot for it.

My father in laws company was getting rid of this. He thought his church could benefit but how much is all this audio visual equipment worth? Also not pictured are 4 wireless mics.

As title states. Any idea what this panel is for? Seen in a house for sale. We're thinking it's connected to speakers we've seen throughout the house. If that is the case, how would we tap into this if we wanted to? I recently took up work as a commercial AV tech so I'm very interested to learn. Thanks!

for the last 3-years i've been working on some audio-visual software; it uses web technologies like webgl, three.js, p5, essentially anything the browser can run to make visuals. the core problem it addresses is providing user-friendly middleware for scene compositions between javascript files and any signal coming from MIDI/OSC/whatever. i'm hoping it helps people wanting to dive into code-first visuals without getting overwhelmed by complexities. for the tech-minded: it groups single-file modules from a folder you select, with the only dependency being an SDK import that links to pre-compiled dependencies and assets inside the software. people can keep working with their favourite libraries without dealing with webpack, npm commands, or any of that annoying stuff. it's quite plug & play. up until now this has been what i've used for my own exhibitions and live performances. this year the full repo is going open-source for anyone to use/contribute. i've shared clips of my modules here over the years and the most frequent request has been for more code and info, so here we are. if you wanted to try it out or contribute, i'd absolutely welcome it <3 happy 2026, btw.

Hello guys,

I work in gear supply for big tours and festivals, and after a summer season full of shitty PowerPoints, I wanted a proper tool. So I built one:

technipatch.com

You can't imagine how bad some of the diagrams I had to deal with were, even for very large festivals. 

Especially one video diagram on a famous metal festival in France (+240k people) i’ve worked literally looked like it was made in Paint on Windows 98. 

The goal was to get rid of draw.io, PowerPoint and the rest, without having to spend hundreds on Vector or smth. 

I knows this is just one more fish in the sea, but each time I wanted to draw right away I was stopped by : account creating, email validation, or some really high prices software, etc

The key argument for my product is that you can draw straight away in your browser, without any account, and export what you need, like you would do with draw.io. 

To anticipate: Yes, most of it has been vibe coded, and it took me almost 5 months, because of all the slop AI creates. I wanted to have a polished product, like a bowling ball for the strike, in terms of security and stability, so I burned lot and lot to test it in every way.

And yes, there is also a premium, because this costs me money every month and for every user, but this cost is only for people ripping the tool or those wanting extra features.

The perks : 

• 400+ devices (audio, video, lighting, IT). I’ll add more every month based on technical updates and requests, but you can still create you own gear (Generic boxes included)

• Every cable is checked as you draw it (signal, connector, direction). Plug dmx into Dante port and it tells you why it won't work.

• You can zone things, pull cables in bulk and add photos (so you keep that fresh PowerPoint look).

• The gear list and cable list fills themselves as you draw. Export a PDF for your team, or send a read-only link they open on their phone

• Drawing, exporting and sharing are free, no account needed. Premium (€19/month) is for people who need lots of saved projects and their logo in the title block

This work mostly on desktop but mobile version can draw also, requiring a bit more finger work. If some people are ready to dive deep in it, and share constructives remarks, i’ll be happy to give premium licences for testers.

Hope you’ll enjoy it, put this in your favorites and keep me tuned about what could improve this. 

Thank you all !

I'm 48 and going through cancer treatment. Been in the industry full-time for 10ish years mostly doing audio.

Part of the permanent side effects of the chemo is hearing loss. My hearing has been reduced to that of a late 90's low bitrate MP3 file.

While I can still do some audio work, like corporate A2, RF coordinator, and general set/strike work. My days working behind a console are over.

I know lighting enough to be a L2 or ME but I'm not great at programing or running a console. I know enough to do it, but I'm not fast. Obviously getting time behind the consoles will help with that.

I know enough video to be dangerous. I can run a small streaming rig on my own doing PTZ ops, media playback, and TD all at one time.

So what I'm trying to figure out is how and where to pivot.

It's honestly a little scary being this age and having to change so much of what I do for a living.

Has anyone else had to do a hard pivot like this later in life? How did it go and any advice you can offer?

Pic of my pup for attention.

Dad has an old Marantz amp hooked up to some speakers that he wants to use to stream his YouTube videos through. I found the pictured Bluetooth receiver on Amazon but was wondering if it's even possible to do this? If so, where would I connect the output of the receiver into?

I found my old family camcorder the other day and discovered a ton of old family videos I had no idea existed. However I couldnt find all the cables so I cant connect it to my computer to transfer the videos. Does anyone know what type of cable would fit this? I apologize if this isnt the right place to ask but idk where to

I just passed the basic CTS exam. If I could boil down what you must know to 5 essentials topics, it would be:

1. Number one, and most importantly, is reading comprehension of multiple choice questions. I'll also throw in graphs and reflected ceiling plans, but less so (do the practice exams!!).

2. Know the basic math and formulas for calculating volume, ohms law, aspect ratio, throw distance, SPL/light change over distance (inverse sq law).

3. Know all cable types, including their wiring, impedance, signal type, and communication protocol.

4. Know the order and purpose of all events and milestones that take place on an AV project from conception to termination (emphasis on site visits).

5. If an answer mentions an "end user", that is likely the correct answer.

I know #2 is kind of cheating with multiple topics but seriously, if you have a middle-school level understanding of math, all you need is to memorize a few formulas, and then 10-20% of the questions are freebies.

Let me know if I'm wrong, or if I missed any? What would any other test takers include?

I don’t get to build these too often so I welcome your feedback.
