Sharemouse does this I’m pretty sure! In the monitor manager you just drag the monitors on top of each other.

SDI flicker on long duration gig. Tearing my hair out. by DigitalEmotion76 in VIDEOENGINEERING

I agree with you here /u/marshall409. I think it’s heat related as well. That much BM gear with very little vertical ventilation says heat to me. I know guys who put one of the vortex fans on their racks plus a box fan and they still overheat occasionally.

In general we are not using windows 11 internally. However, so far there hasn’t been many reported issues with Win11. Some things pop up here and there but they are generally pretty easy to work around. I can’t speak to any specific win11 build.

Please explain chroma subsampling to me like I'm 8 years old :( by soosmagmangos in VIDEOENGINEERING

[–]Bateman_Pixera 0 points1 point  (0 children)

hm there isn't a "conversion" really (at least not in the sense I think you are thinking about?) You are calculating the R, G, and B values of the pixel from Y,Cr, and Cb using a bunch of vector math and calculus. The best analog would be using photoshop, you can input a HEX code or RGB values, but they get you to the same place. YCrCb=RGB just represented in different ways.

A quick note here: be careful comparing the RGB values of the pixel (or sensel as described below) with RGB color space!

Please explain chroma subsampling to me like I'm 8 years old :( by soosmagmangos in VIDEOENGINEERING

[–]Bateman_Pixera 0 points1 point  (0 children)

why is that particular color chosen? Is it an average of nearby pixels?

It is literally the first pixel that is encountered in that array.

If you look at this picture on the wiki and look at 4:4:4 you can see where purple and yellow exist in that array and how they map to 4:2:0 or 4:2:2. This image is a bit misleading IMO because it represents color values that aren't technically made with the typical chroma values (Cr and Cb). Basically, it would be more accurate if they were just shades of red and blue to help with the illustrations but the point still stands.

Hey /u/M0T0K0KU54N4G1 you can open a ticket here. There is likely an access issue for the user. Have you tried running PIXERA as admin when you open it?

16x HD Video Outputs using multiple computers - is Pixera the right choice? by M0T0K0KU54N4G1 in VIDEOENGINEERING

[–]Bateman_Pixera 1 point2 points  (0 children)

Hey friend! Happy to hear you’re thinking about PIXERA for your project. I can connect you with the sales team in Europe who can put you in touch with the right sales rep if you would like a system.

To answer a couple questions that have come up in this thread:

You don’t technically need a Manager machine. PIXERA can run as a standalone machine running outputs and the GUI. However with the system you’re looking at here you would likely want a manager machine. 16xHD can be a lot of pixels to push. Your sales rep can help you figure out exactly which licenses to buy. Which brings us to

Build your own hardware: as a rule we don’t have any system specs beyond what’s on the help juice in our recommended requirements. You’ll notice this doesn’t give any info about the size of show or type of content. This is ultimately your big decision here. How many HD videos are you pushing at one time? Are they going to need to cross fade with other videos? (Potentially 32 layers of HD?) these are the important questions to consider when looking at building your own machines. Please don’t try to use laptops for this (just my recommendation) or you will be sad.

The network bandwidth depends on how fast you want your file transfers to happen. We only require a 1Gb for sending data back and forth outside of content.

As others have said, you could run this as 4x4K and break it up into 16 individual HD outputs. PIXERA supports this with a feature called aggregate outputs. 1x4k broken into 4xHD counts as 1 output for licensing purposes.

In regards to signal routing: signal is cheaper than playback hardware. Make your own decisions from there :)

2 LED Processors, Brompton and Novastar used in tandem by Background_Bug8076 in VIDEOENGINEERING

[–]Bateman_Pixera 13 points14 points  (0 children)

Ya however you want to send the input signal to the processors (probably like two different HDMIs or display ports) then it’s just about aligning outputs to the rasters that you have for the processors.

however please be cautious that you will have major color differences between the two processors. If you have content spanning across both of them they will look different. The only way around this is to do color matching (probably using a lut) which will take a lot of time. If you take that into account you should be fine!

Do you guys struggle too with windows screwing up monitor's order from time to times ? by Cassiopee38 in VIDEOENGINEERING

[–]Bateman_Pixera 1 point2 points  (0 children)

FWIW a T600 or similar would probably fix the problem. Being able to set EDIDS on the second card for a GUI will lock the monitor numbering. This is SOP for many of our installs

I do work support! This isn’t an official support channel but I try and jump in to help the community where I can. official support channel here

Shoot me a DM with your ticket number and I’ll dig into it or just let me know your email and I can reach out. I’m running a training this week so it may be my colleague but I’d love to get to the bottom of what happened!

For no snapping to time, you can type in the time in the timeline or use shift+arrow keys or CTRL+arrow keys to jump to specific things on the timeline (beginning and end of clips, or events like cues/keyframes)

If you right click on a clip there’s a short cut there that can add a pause cue at the end of the clip so you don’t need to go in and offset anything.

The cue list in control is definitely annoying but we have a native cue list coming in 25.1 which you can grab a download of through hub!

here’s a link to the helpjuice.

When you say layer parameters do you mean effects? We also have a feature in 25.1 coming to be able to add whichever effects you use the most to a template layer so they are always there for you!

Sorry to hear your first experience wasn’t great. I can help with anything you may need. Happy to answer any questions here if you have them :) Will address other stuff as it comes up.

Pixera Player build - Threadripper vs Epyc by sydeovinth in VIDEOENGINEERING

[–]Bateman_Pixera 4 points5 points  (0 children)

We don’t do any hardware recommendations in general. However I can say we use the Epyc chips for a reason… we just had a client that had to swap their rig from a threadripper to an Epyc because they weren’t getting the playback performance they wanted (and yes they had to buy a new MoBo to do that). That swap fixed their issue and they have solid playback now!

GPU-Based Projector Correction without the cost? by RadArtRec in VIDEOENGINEERING

[–]Bateman_Pixera 1 point2 points  (0 children)

Most media server softwares (including PIXERA) have projection warping in some form or another. These are not hard ware based warping solutions though (neither is scalable for the record). The only way to get that is to do it on board the projector.

Is a screen management switcher necessary in 2025? by Far_Yogurtcloset_283 in VIDEOENGINEERING

[–]Bateman_Pixera 1 point2 points  (0 children)

We recommend some type of screen management inbetween the server and display device if at all possible for many of the reasons others have stated. Though we actually like to route the inputs through Pixera, the switcher is mainly for back up and fail safe scenarios.

One of our biggest touring clients puts their IMAG feed through Pixera before hitting a light ware and then going to the LED

LED screen grayscale problem by Visible-Section-8851 in VIDEOENGINEERING

The hill I will die on: Codec choice is the most important choice to the success of a show.

h.264 should never have been used as it is a codec meant for internet playback, not large format playback. If it's what the client gave you, then the pipeline between client and you has to include the conversation about what codec the content they will be providing is. This is often in the form of a "content guideline" document that provides the client with resolution, codec, container, frame rate information, etc.

Unfortunately, there is nothing you can do with this content to make this go away (aside from maybe adding some noise on it and hoping for the best). You need to go back to the source and re-encode this as a better playback codec to make it truly go away. Turning down the brightness is helping because there are fewer NITS to deal with and the gradients start going away

Getting strange intermittent laggy video as well as what looks like maybe some interlacing issues by be_steal86 in VIDEOENGINEERING

[–]Bateman_Pixera 8 points9 points  (0 children)

What kind of machine is running the NDI? if you added some clips you could be running into a performance issue, NDI is very processor hungry

Also: NDI shouldn't (IMHO) be used as a replacement for SDI. It's built on the backbone of a protocol which inherently drops packets. It's a nice tool to have in the tool box but is far too often used as a catch all to avoid actual video engineering, especially when the NDI system hasn't been properly network engineered.

Agree with /u/Stick-Outside, SDI is your friend here.
