Yes, but I don't control what is being used in room. I just come and record. VGA is still used almost universally to send laptop outputs and slides.

AJ Henderson

yeah, I realize that, just saying, my information is a little dated when it comes to VGA stuff

and back in the day, quality was kind of mediocre just because nothing was fast enough to handle high resolutions

fredsbend

That's okay. I don't know enough to know the difference.

AJ Henderson

when you were outputing to 480i it didn't particularly matter how good the capture was of the VGA input

fredsbend

I can handle quality being mediocre. My customers don't really care that much. I'm selling lectures, not hollywood movies.

@AJHenderson So then from here, I need another peripheral that converts the YPbPr to USB?

AJ Henderson

YPbPr is supported by either the Matrox MX02 or the Intensity

or just about any other form of external or internal capture device made

YPbPr is the technical name of component video

fredsbend

00:07

@AJHenderson I see. That's what I thought.

@AJHenderson I think it's MXo2. The letter o, not the number 0.

AJ Henderson

ah yes

so it is

fredsbend

It's a thunderbolt thing. Any usb 3.0 option?

AJ Henderson

oh you are working with a laptop aren't you

fredsbend

Can you send two video feeds though it. One using the hdmi and the other using the component?

@AJHenderson yes.

Is that a problem?

AJ Henderson

@fredsbend doubtful

and no, not a problem, just forgot that PCI Express slots aren't an option for you

fredsbend

00:18

Yeah, didn't think so.

@AJHenderson No, I'd have to use an express card thing, if that were something that existed.

AJ Henderson

there is an expresscard 34 version of the MXo2

bhphotovideo.com/c/product/592001-REG/…

that's the host card

fredsbend

So you get the mxo2 and that card and there is a cable that connects the two?

AJ Henderson

bhphotovideo.com/c/product/618347-REG/…

that bundle includes both

and if you wanted to be able to use the MXo2 at home on your desktop, you could also get a PCI express host card

and you would just unplug the MXo2 from one and plug it in to the other

all the fancy electronics are in the breakout box

the host card adapter is just the IO to the system itself

(welcome to the wonderful world of video processing accelerators, they take a bit of getting used to)

once you know how to work with them, you wonder how you ever lived without them though

fredsbend

Yeah. Lots of little doohickies here and there.

AJ Henderson

hmm, the mxo2 supports rgb component

so you might not even need that YPbPr converter

fredsbend

00:28

So the plain wire would work.

That's nice. Cheaper.

AJ Henderson

quite possibly

fredsbend

easier.

AJ Henderson

if you haven't seen it yet matrox.com/video/media/pdf/products/mxo2/en_compare_models.pdf is the model comparison

fredsbend

I did run into that.

AJ Henderson

and I'd recommend the max version of the mini

simply for the H.264 encoding

fredsbend

00:29

I think I need to find a laptop with a thunderbolt port now. I prefer windows because of cost and less likely to be stolen, especially if you make the outside look beat up.

@AJHenderson Yeah. That's what I was leaning toward.

AJ Henderson

probably easier to find one with an express card slot

though both are becoming sadly rare

fredsbend

Is thunderbolt not going to pass the time test?

It's faster than usb3.

AJ Henderson

who knows, Apple is sticking to their guns with it

but everyone else has always prefered USB to firewire

fredsbend

well they aren't really known for going with the flow.

AJ Henderson

and thunderbolt tries to do too much making it a bitch to try to implement on hardware

it takes the direct bus access of Firewire, which was bad enough, but adds video support as well

you can't even implement it on an expressport

fredsbend

00:32

I felt like it was a little overly complicated when I was reading about it earlier today.

AJ Henderson

where as everyone else is headed toward the displayport/usb3 route

fredsbend

I still don't know why rj45 ethernet is not taking over everything. 10gbps and 100 watts. What's the hold up?

I would think a breakout box that connect to ethernet is out there, but I've only found one and it was dvi only.

AJ Henderson

usb 3.1 can do 10gbps

fredsbend

didn't know that existed. What about power. Probably only 10 watts.

AJ Henderson

and ethernet has some reliability and latency issues I think

fredsbend

00:35

oh?

AJ Henderson

though I'm not sure on that

because ethernet breaks it up over multiple lines

which means you have to serialize and de-serialize it

if it is a single data stream

atleast as far as I know

I don't know much about the 10gig specs though

fredsbend

I think I remember reading that it goes in intermittent packets or something like that. So it doesn't move in consistent amounts. idk.

AJ Henderson

I just know that traditionally ethernet has not been well suited for it even though it's always been faster on paper

kind of like how USB 2 was faster than firewire on paper, but actually firewire was faster

apparently USB3.1 can optionally go up to 100W

as well

5 amp 20 volt

fredsbend

01:15

@AJHenderson huh.

Sorry. Screaming baby, now it's dinner time. Will talk later.

Probably tomorrow morning.

15 hours later…

AJ Henderson

16:42

@duvrai hey, wasn't sure if you were aware of this room, but since you seemed to be getting active I figured I'd mention it to you. Glad to see another skilled video person around, seems like you have a solid knowledge of some of the platforms I'm weak on too.
