Change white balance of Panasonic PTZ cameras using IP command and Streamdeck?

I have the AWUE150 cameras and an RP60. I'd like to set a few white balance presets using exact kelvin numbers, but the cameras and RP60 only have one VAR (variable) setting. Is it possible to save and send kelvin numbers via Streamdeck to the cameras?

Help fixing an old Sanyo Beta VCR-4400

I hope this is the right place, but I've got an old Sanyo Beta VCR-4400 deck that mostly works but won't rewind or eject tapes. I have a set of new belts to replace the existing ones with. I'm looking for a service/repair manual or troubleshooting guide for this model* and haven't had any luck in the usual places (manualslib, ebay, etc.) r/betamax seems to be a dead forum, otherwise I would have posted there first. Does anyone have any suggestions as to where I should start?

*I've never repaired a VCR, but do have electronics repair experience.

HDMI capture card help

Hello,

I'm looking at 2 capture cards for 4k30p with 4 inputs, all HDMI for our church.

I narrowed it down to magewell pro capture quad HDMI card and Yuan quad 4k HDMI input.

Can somebody with more technical mindset recommend one over the other? We do need it to be PCIe x4 which is why we passed on the BM capture card since that one is x8.

Price difference is $300 more for magewell.

Thank you!

Identification SDI

Hello guys. I have a question. I am dealing with diy the production of a modified version of the BNC galvanic isolator, and after inspecting the finished, comercial sold product, the SDI isolator, I cannot find out what type of isolating transformer it is in. I am sending a photo. It's also strange to me why the shield is divided into two branches that connect again at the end of board. Thx for your time.

Weather Protection for AW-HE130 PTZ Cameras

Hello everyone,

I’ve been exploring various options for protecting my gear, but I haven’t found a solid solution yet. I’m starting to get more offers to cover festivals, and I want to make sure my equipment is well-protected, especially from rain.

I own several Panasonic AW-HE130 PTZ cameras. I noticed Portabrace offers a rain cover for them, but the reviews aren’t great—apparently, it can obstruct the motors and limit functionality. I’ve also heard about dome-style enclosures that could be mounted with C-Clamps on tripods, which seems like a promising option if I can find a reliable source.

What do you all use to protect your cameras from the elements during outdoor events? I’d appreciate any recommendations or links to products that have worked well for you.

Thanks in advance!

Novastar VX2000 Pro -- Anyone hands on?

Has anyone gotten hands on with a NovaStar VX2000 Pro?

I'm looking at some LED purchases for Q2 and had settled on an MX40 Pro with some fiber breakouts, but then I saw these have popped up since I last did some research, and it piqued my interest.

This will be my first fiber assisted setup and I'd appreciate any real world insight into going one way or another. This is for a deploying on corporate meeting event sites, mainly in ballrooms.

I'd appreciate any experiences you're open to share, thanks in advance.

Kiloview P3 Mini live

We are thinking of bonding the Kiloview P3 mini device with 3 sim cards and using the 10 km running race as a live broadcast on a motorbike. There is a huge price difference between LiveU and Aviwest. Of course, there will probably be a quality difference. But we do not have enough budget to invest in a new LiveU or Aviwest. In your opinion, this device will be sufficient in quality for a 4Mbit - 6 Mbit broadcast with 3 4g Gsm sim cards.

Problem with my he130

Hey guys

I have some old Panasonic he130 that works fine BUT it seems that the image quality is not that good compares to canon n300.

It seems "blurry"/"dirty"

I'm working with decklink duo capture card and vmix (1080p25 projects) AND when i work with other type of cameras, everything seems to work fine.

Do I have to repair them or is it normal ?

Thanks

Which playback option better - One huge (4x4K width) or 4x files 4K width each?

Hello everyone
What you think
There are two options for playback by media server, in my case, its disguise d3 4x4pro, with SSD 2.5" drives

  1. One huge video file with resolution with 4x4K (15360px)
  2. Four video files with resolution with 1x4K (3840px for times)

Content is same, hight of video also same, just divided on not.

Hidden Camera Production Equipment

Hey everyone,

I’m gearing up for a production that requires a bit of a unique setup. I need to place about a dozen “hidden” cameras around a store. They don’t have to be actually hidden, but disguised to blend in, kind of like security cameras.

Here’s what I’m ideally looking for in these cameras:

• POE powered

• NDI built-in

• Dimensions no bigger than 3.5x3.5x6 inches

• SDI outputs, HDMI out would also be a plus

• Internal recording capabilities

• Must support 1080p at 60fps, though 4K would be a nice bonus

So far, I’ve considered a few options:

Zowiecam: This one’s pretty close to what I need. It’s super compact, affordable, and supports NDI, SDI, and HDMI. The only downside is it doesn’t record internally but can record to a NAS. Plus, it allows control over zoom, focus, gain, WB, and shutter via VISCA commands on Companion.

GoPro Setup: Thinking of a GoPro with an HDMI to NDI converter, housed inside a 3D printed “security camera” enclosure. The challenge would be managing shading and triggering record start/stops.

I’ve also looked at these, but they fall short on several features compared to the Zowiecams and are quite a bit larger:

• Logitech Mevo Start

• Logitech Mevo Core

• AVKANS Go

• NearStream VM33

Would love to get your insights or recommendations if you’ve tackled similar setups or know of any cameras that might meet these specs. Thanks in advance for your help!

Realtime Graphics Options

Our company is considering Ross, Chyron, or Vizrt for real-time graphics—lower thirds, fullscreen, video walls, and AR. Which would you recommend? We're looking at the pros and cons of each and the support aspect since we don’t have a large engineering team. Reliable support is a big factor for us.

Update:

  • Sports and Entertainment streaming, different locations in US and Latin America
  • We will have a few real-time designers
  • We need simple graphics but the ability to do some complex AR graphics.
  • A small engineering team to support this
  • We need to be able to share graphics, images, and clips in different states and countries easily so that they can be played out of different systems.
  • We are looking at cloud production and IP, so a company that is investing in these technologies

How do you manage a lot of encoders and decoders in your rack?

In my rack I have a few trays that hold about 15 total encoders / decoders. A bunch of Magewell NDI to AiO, a group of Magewell Ultra encoders, And a half dozen Kiloview NDI to SDI devices. Placed them flat on a ranch tray and have fans above to keep them cool.

I am looking for. Wat to manage these best. Maybe a 3d printed mounting base for all of them?

Looking for ideas from those who have over 6 encoders or decoders manged in a rack. How do you keep everything clean and manageable?

Thanks !

PTZ Camera Recommendation for Live Streaming Worship Service

Hi All! As the title suggests, I am looking for a camera for our church. The budget is around $3,000, the house of worship is well-lit, and we have services in the morning and evening. I am very new and do not have any experience working on PTZ cameras. However, what we need from a camera is that it has high-optical zoom.

I've looked at other threads and seen Redditors throwing names like PTZOptics, Canon, Panasonic, etc. and I don't know which ones to go for.

Any suggestions are most appreciated! Thank you very much!

Resources to learn more about how LED walls work

Hello friends! I currently work as a head electrician at a theatrical roadhouse, thru this I've learned the basics of the basics of what cable goes where on a LED wall Id like to expand and go on the road, but many of these tours require the electricians to also be the video tech, and I fear my knowledge doesn't go deep enough Anyone got some good book suggestions to learn a bit more about that side of things?

Thanks in advance <3

Help with smoothing the scale / getting rid of horrid banding on vid

Hello,
I'm having an issue with crispy banding on images when scaling in & out.
Images are 4k, projector native resolution is 3840x2400- we're feeding footage via disguise.
I'm scaling a PNG image from 1% up to 80%. When it moves, the image becomes very banded/crispy. No doubt it's a resolution issue.
I've tried frame blending as a node. Doesn't work.
I've also tried to export a movie version via AE & Premier, with blending included... still doesn't work.
Any tips?

SD-SDI vertical roll/stutter at top of frame

Recently started delving into SDI and have run into an issue.

I'm working on a portable setup for capturing SD video from an old ENG camera (for fun/art), and decided on a Ninja Samurai Blade SDI recorder/monitor.

I'm converting the composite video from the camera to SDI using an AJA D10AD, which then goes into the Ninja.

This is giving me a flickery, vertical roll visible at the top of the frame:

[video1]

Interestingly, it appears over the OSD on the Ninja (whose screen is otherwise fine with no input).

The issue persists with the AJA outputting color bars and the camera disconnected:

[video2]

And the affected area shows as black in the recorded output:

https://imgur.com/a/kEmIkna

I've tried a variety of BNC cables with no change (using what appear to be good quality cables; I purchased a large lot of them from RePC when I was up north a few months back).

I don't have any other SDI equipment to diagnose with, but I'm ready to purchase anything additional if that's where things need to go. This particular equipment is new to me, so it has not been tested outside this setup.

Any thoughts/suggestions, or other recommended equipment?

iOS screen mirroring device

Many of the better syncs out there let you natively screen share on from an iOS device. But a lot of projectors TVs etc don’t. AppleTV diss the trick but I’m looking for a very inexpensive device that will bring in airplay and spit out HDMI. Any suggestions?

Atem Constellation ME4

Maybe I am missing something obvious here but we are planning to purchase an Atem Constellation for our church and use it for house, confidence monitor and live stream mix. I see a 1/4” jack left and right out, is this the way to get audio into our house soundboard?

Is there one audio out even though there is 4 mix effects?

Xpression GPIs

Is there a way to create a GPI in XPression that changes a TakeID to a predetermined TakeID.

For example, I have player caps for basketball. I would like to press a players name on my GVK switcher, tell XPression to change their cap TakeID to my set player cap TakeID, then press my player cap to run it. Does anybody have any thoughts on this?

If not in the XPN interface, could I script it?

Teradek Ace reviews?

Hi all

We like some of the Teradek stuff and a client has asked for some way for an influencer to wander onstage with a GoPro and have it sent to LED wall.

Ignoring the latency issue for a second (they don’t care about a few frames unlike me), we were looking at Teradek Bolt LT or Ace as a compact wireless transmitter for this configuration. Anyone got anything to say about these products in this setting?

We would mount the receiver up on top of the wall on a magic arm so that it has Line of Sight most of the time and it won’t get too far away from the stage.

Show is 200 cap at a large computer mfr. corporate HQ. Any reasons this is a bad idea / won’t work?

Thanks
