  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Arri Alexa and Mysterium-X...

No light meter I've ever bought has been accurate to my certified and calibrated lab tools that I rely on for precise camera calibration duties.

M Most you're welcome and also free to do whatever you want but I do not care so much to whom you have on your ignore list.

Is't a pity that you couldn't get what I wanted to say and that's clearly like this:

"Even ARRI today is using a "fake" language just because like everybody else they finally have to sell this new camera."

Nothing wrong with it and nothing pro RED in it.

We started to talk about a language that is used in the latest marketing and some people here immediately getting "sensitive".

A part of digital revolution is to "break bones" of some old bad manners and language that is used in the industry.

That's is exactly a part of mission of the latest digital rebellion.

Also RED1 is just one of digital cameras I owe, work and using it together with ARRI MFF-1 follow focus and ARRI Lite light that are all pretty good.

I like to mix a different things (old and new, also a famous brands and newbies) together in a sort of collage or assemblage technique as my main concept.

Normally and also with a kind of polite manners if you do this step you should inform me privately

but if you want to make a gain from it in a public than after you'll get also from me what you actually deserve it:

"The Most Profound Voluntary Ignorance of knowing anything about anybody, but abounding in preconceived opinions about everything!!!"

BTW, still I do not have anybody on my ignore list that means I do not have ignore list at all.
 
I'm not talking about the terms Mb/MB I was talking about your use of them. Data rates for codecs have been measured in Mb, RedCode was the first to use MB, it caused confusion.

Redfocus is being called a Backfocus calibration tool, it is a Flange Focal Distance calibration tool.

MiniBNC/XLR's do exist, which is what I said, but they are not Industry Standard on CAMERAS.

I know you're a smart guy, try re-reading what I said because you didn't understand what I was saying at all.
 
Actually, back in the day, video compression data rates were expressed in MB - for instance the old Miro DC30 (my first video capture card) went "up to 7MB/s" (note: not 56mb/s). Usage of megabits for codecs reminds me of how the Sega Mastersystem and other consoles started to use megabits for their game cartridge storage capacity, probably due to the megabit number being 8 times larger than the megabyte number, and hence has more positive marketing use.

I think we all hammered out the digital cinema camera lingo on this forum.
It was not started by only one individual. History is being made here.
New technology requires new terminology.

I remember thinking about using MB instead Mb for codec speed since numbers got a bit too long.

Before long everybody here started to use MBs
Even recently when referring to resolution of the sensor,
we started to use MP referring to Bayer MP sensor resolution as oppose to CCD Mega Pixels.

People were mixing 4K cine formats with 4K sensor sizes and sensor MPs, vertical lines count from TV formats with horizontal pixel counts and pixel Bayer counts. What a mess I was thinking.

Day later Jim posted great explanation of resolution terms with graphic examples.

And where do you think the phrase ‘revolution in resolution’ comes from?
 
Converting between MB and Mb is trivial. That, coming from a tech background, is something I've done on a daily basis. Digital is complex and screwed up when it comes to standards 'cause a large majority DO NOT FOLLOW THEM. Fact. :smash:
And they use Gigapixels and MB because it occurs to be natural when talking about large numbers. Not different from saying 1TB instead of saying 1,000,000,000,000 bytes. The later just doesn't make sense (an exaggerated example,
but you get the gist of it). I don't know. Just offering my perspective of how it makes sense to someone standing on the outside looking in. :Angel_anim:

Would that be win over the M Most ;-)

In the quest to "win over" the customer in our biz the "creative" use of technical terminology is to be expected - see John Galt; Marketing Pixels, for a particularly impressive demonstration :001_cool:

What are the chances that someone without a dog in the fight will conduct seminars about the technological side that would actually be attended by a significant number of practitioners... (see flying pigs).

In the meantime we simply size up each person we communicate on technical issues with, then modulate our terminology to suit. The truly dangerous thing about that approach is when I explain something to a producer in "producer's terms", then they parrot it to others with a critical omission or creative embellishment, and the next thing I know the Director or DP is up in my grill about how they just had resources curtailed based on something I said :violent5:

Ultimately Graeme is right about precision in the use of language in a professional context. That said, how practical is it? With NAB upon us, absolute truth in definitions will likely be the first casualty.

Dynamic Range and Latitude

Dynamic Range and Latitude

To avoid doubt (and as Graeme succinctly described)

Dynamic Range is a measure of the total range of tones that can be captured by the camera.

Latitude is a measure of the allowable error in exposure. .. i.e. it is the camera's DR, minus the scene's DR.

as in " latitude: scope for freedom of e.g. action or thought; freedom from restriction "


So, if as an example your camera has a DR of 13.5 stops and your scene has a DR of 7.5 stops, you would have Latitude of 6 stops.

Whether that is 6 over/0 under or 3 over/3 under or 0 over/6 under depends on where you set your "mid grey" exposure on the sensor.

Recently, at the studio:

"Have you heard? RED RAY plays out 4K at 15 megabits per second?"
"15 megabyte per second? Neato."
"No, 15 megabits."
"Now there, if I had 1 € for every time I've explained the difference ..."
"Right, you'd be rich."
"Right. I should charge you, too."
"Don't bother, I know the difference."
"15 times 8 divided by 24 ... wow, 640 kilobytes per frame?"
"Actually, it's better than that."
"A megabyte is 1024 kilobytes, not 1000!"
"Yeah, you keep saying that."
"640 kilobytes per frame, not 624."
"It's, like, much better than that."
"What, their megabyte has even less kilobytes?"

There's an intermission which has the tech triumphantly rendering out SD timelines, just for the zing of it. Lunch break ...

"Just checked out the net. Hey, RED's got this megabit typo all over the place!"
"It's not a typo."
"I'll tell you what it is. A scam, that's what."
"It's confusing, I know."
"You should think, them building those gigapixel cameras and all, they'd get megabytes right."
"Disturbing, even."
"They're saying you can put a feature film on a memory stick. The nerve!"
"4K, yes. Outrageous."
"4K? I forgot. What a scam."
"Yes, everybody knows."
"Hey, can I have some of your fish?"

And of course, in that case the mention was megabits in reference to the max DVD data rate of 10mb/s as that was the target of the project.

MB = MegaByte
Mb = MegaBit
(that's standard abbreviation)

REDFocus is product name not a term.

MiniBNC and MiniXLRs exist, we didn't make them up.

Gigapixels, again a commonly used term.


Reading your past posts, you're clearly a troll. What's your real name?
Click to expand...

2nd that request Blaire Johnson... whats your REAL name and location?

Pathetic you cant be a man and post your opinion without fear of making an ass of yourself like the rest of us do.

All part of community building... your attitude sucks as does your delivery.

M. Most has a STRONG opinion, disagrees with people a LOT on here... yet always manages to be respectful, even when he is pissed off.

You Mr Troll, are annoying and not helping advance anything but our collective intolerance for Trolls. So come clean with WHO you are or politely bugger off. Thanks!

Thanks. I've learned a lot about Internet etiquette from my friend David Mullen...
 
Alexa short filmed in conjunction with ARRI:

Let's hope the horrendous green-screen and VFX work was a by-product of a rushed 'camera-test' production - and not an inherent Alexa keying flaw? Looks like they had too much noise in the key and ended up with a lot of fringing. Can't say I'm that impressed with the consistency of the black levels in the grade either (watch it in fullscreen HD if you can).

Having said that, kudos to Stargate for cramming so many lighting conditions and variables into a short film. Good way to put a new system through it's paces.
 
Badly compressed and very noisy. Not a good camera demo. Arri can do better than that. And why no full rez stills?

Weird... Did anyone else think that the guy who opens the gate and lets them in was going to murder them? Anyone?

Maybe I've just been watching too many crime shows, but they tend to use those dark settings below bridges a lot, and that guy did look creepy...
