Headphone Calibration. What about it?

RoadsidePicnic — Mon, 07 Aug 2017 07:46:29 +0000

Is there any real benefit of using a calibration profile in a decent headphone (let's say, Superlux Hd681 or better)?

Second, if there's actual benefit in it, when it becomes practical to spend US$ 120,00 on a calibration plugin?

Found that Sonarworks Reference 3 Headphone software and people reviewing it in the internet got me curious.

Here is a quote from their website:
"Hi-end studio sound from your headphones. Headphone calibration is the process of measuring and adjusting the frequency response of headphones in order to precisely match flat and neutral sounding studio monitors in a well treated studio. Standard studio headphones are transformed into perfectly-engineered precision devices. By giving yourself the gift of accurate sound, you can mix and master with total confidence."

And here is a quote of a review by Matthew Weiss:
"So is this product just a fancy EQ? Well, yes and no. Essentially, it is just an EQ. However, the curves it’s recreating are not curves that you could simply dial in by ear or with simple measurement of white noise. Sonarworks notes that there is “resolution up to 16000 correction points” which is way more than any market EQ can give you."

REC 2020 - Finally, REC 709 is getting the boot

"People mistakenly call it a color space," Griffis said. "It's actually a two-dimensional plane and what you really need to know if you're a creative is this is your palette of colors but what the horseshoe chart doesn't tell you is how bright each color can get. White will always be the brightest because it's the sum of all three primary colors."

"So we've got this interesting problem that we've lived with for the better part of 60 years where the colors in film go out farther but you can't get as bright and in television there are less colors but you can get brighter," Griffis told Gizmodo. "And the practical consequence of that for the content creator is that the Red Bus of London that looked so great in the movie looks like Campbell's Tomato Soup on the Blu-ray unless someone does something."

So Dolby (who makes the most amazing video monitors) finally did something. And When it hits TVs and Computer monitors... all this REC 709 bullshit can finally fuck off.

I am so damn happy... you don't even know.

gammaPATT: little software tool to check quality of monitor calibration

tida — Thu, 14 Jan 2016 08:09:56 +0000

Hi, I would like to share the little software tool gammaPATT which I just developed for fun. It's free for everybody. It creates checkerboard like gamma patterns. You can check gamma calibration of your monitor at different Luminance stages. It also shows you how your monitor performs at different viewing angles.

Hope you will enjoy. Please let me know some good ideas for improvements.

Note: Square in the middle of color frame should appear invisible. Left square should be slightly darker and right square slightly brighter. For that purpose both L (Luminance) values should be equal. Click on lower L value (for inner Square) to adjust to the upper (for outer checkerboard) automatically.

MAC version will come soon;-)

Field monitor calibration for shooting

flablo — Tue, 28 May 2013 10:43:09 +0000

Hi, I have a Marshall V-LCD50-HDMI which I use with GH2 and GH3. I noticed the image being completely different from the one I get on the camera screen and in the recorded file. Anyone has tips/thoughts on this? Here on PV I only found tips on computer monitor calibration, not on field monitor.

This is my experience: looking for calibration tips, I found this

which seems pretty good. Anyway the first problem is getting a color bars reference image on the monitor: I tried taking some native jpegs stills, modifying them placing the bars over the image image and then saving, but nor GH2 or GH3 accepted to read the image. I finally managed through a minidv camcorder connected to FC to record and display the image on the monitor, and followed the procedure from the tutorial. Anyway during my last shoot I realized the image was once more different than what I was recording, so I'm somehow back at the beginning. The V-LCD50 is not really a lower-end monitor and it should perform decently in terms of color, so I'm quite upset for not being able to use it as a reference.

Thanks

Rookie Monitor Calibration Question - Is it really important?

matt_gh2 — Sat, 02 Feb 2013 20:38:00 +0000

Here's a rookie question. Is it really necessary to calibrate the monitor you use when editing? I ask this because I guess when the editing is being done...whether you have a calibrated monitor or you don't...it seems you still have to export your footage and view it on the all the types of screens your audience would view it (computer monitors, hdtvs, standard def tvs, iphones, ipads, theater screens).

I currently edit in Adobe CS6 on a PC laptop with a less than stellar screen (one of those ones that looks kinda washed out). I often will connect the Laptop to a 62" HDTV or a 42" HDTV to edit as well. So I've basically just been exporting footage and viewing on a variety of screens...and adjusting as necessary.

My only guess is that a properly calibrated monitor can be defined as one that somehow sits in the middle/average of what all the different audience members screens are?

All advice is much appreciated.
