Color Correcting Monitor on Set

Not quite a FCP question, but...
We have a monitor on set that is used as part of the background. Of course it comes up blue on camera. I've tried adding various amounts of a red overlay to my projects, but I still can't seem to get it right. I know there's no magic formula, but does anyone have a suggestion of how much of what color to use that would at least get me in the ballpark?

Your monitor is white-balanced for a color temp of approx. 5600K (Daylight)and your studio lighting is most probably running at 3200K ("Tungsten"). While "CTO" gels can be put in front of the monitor screen to color-correct for the difference in color temp., your other options are to re-balance the colorimetry of the monitor (tricky at-best if there isn't a menu selection to do so), or to light your studio with 5600K lighting fixtures (either Compact fluorescent or "HMI"(Very expensive to rent HMI fixtures). I'm an engineer in the television broadcast world, and I've been dealing with this problem quite regularly over the years. Your own eyes can correct for color temp. differences, but a video camera's imaging sensors have to do it electronically.

Connecting Color Correction Monitor To My G5 (Help Please)

Hello everyone. I'm getting ready to begin color correction on a DV feature I've just finished audio post on. I have a Macintosh dual 2Gig G5. It's an early G5 that has PC133 slots, however, and is NOT HD compatible or ready. I cannot use an HD video card (AJA, etc) or an HD monitor for cc - and simply cannot afford an AJA IO - so I'm going to work with SD. In the research I've done it looks like the JVC DT V1710CGU - a 17" monitor that is said to have decent critical color correction capabilities is what I might purchase (here's a link to one)
http://images.google.com/imgres?imgurl=htt...s%3Den%26sa%3DN
How would I be able to get my video out to the monitor using my G5? The reason I ask this is because, simple as I thought it was, when I went to purchase the actual monitor and the tech tried to use it to see video from his laptop . . . it didn't work.
He plugged from the computer to the JVC monitor using a DVI to VGA adapter connected to a VGA to RGB cable (the DVI end of the adapter being connected to the computer) and connected that RGB end of the cable into the JVC.
He tried a lot of different monitor formats in his laptop to try to conform the computer's signal for the JVC, but nothing seemed to work. I myself have a Sony DVMC-DA2 analogue to digital media converter that I used to get video from the G5 to view on an external television set. The media converter is connected to the G5 via fire wire, and then connect to the tv using RCA cables, but the tech said that you DON'T want to connect the JVC monitor using RCA cables (composite . . . right?). He said use RGB cables (component).
Does anyone know, again, how to be able to get the JVC DT V1710CGU to output video from my G5 (Final Cut Pro specifically)?
Any help would be appreciated.
Thank you,
Javier Calderon

Thank you much for the prompt reply, David. I really appreciate it.
I just realized right now - after reading your post and investigating, that is - that my Sony DVMC-DA2 has S-Video in and out. This seems that it would be sufficient then, no? So . . . what's the proper connection then? Let me know please if this is it:
Connect my Sony media converter to the G5 via fire wire. Go out of the media converter via S-Video and IN to the JVC color correction monitor . . . via . . . what? Does the JVC monitor have S-Video in?
Thanks again for your help, by the way. You've already clear me up a bit.

Sony PVM 20N5U a Color Correction Monitor?

Hello, folks. Didn't know where else to post this, so I'm trying here.
I have a Sony 14M2U that IS indeed a professional grade color correction monitor. However, I was recently given a Sony PVM 20N5U and I'm wondering if this one is a professional color correction monitor as well. I looked online, but couldn't find any specific information on whether it was or not.
Any help resolving this would be greatly appreciated.
Thanks much in advance,
Javier

The N5U series is what's called a presentation monitor for general viewing, hardly anything to be used for color accuracy. http://www.videosupport.tv/specs/Sony/Brochures/PVM20N6U.PDF
I also wouldn't call the PVM-M2U line of monitors "grade" monitors at all. While feature rich, they have P-22 phosphors and a vertical resolution of only 600 lines. The M4U line of monitors had 800 lines of vertical resolution as well as SMPTE-C phosphors in the tube.
However, your 14M2U is a heck of a lot more color accurate (if you've had it benched by a technician recently) and consistent than that 20N5U.

Color correct monitor

I am looking to buy a good color correct monitor for working with photos and eventually printing them in book. My tech friend recommended Eizo as the best and said that I may not have to get a top of the line one. Does anyone have an opinion about the Eizo ColorEdge CE210W, which is specifically for working with photographs, or the FlexScan S2100, which is a standard model? How about the LaCie 324? I will be printing in Asia and in Japan Standard profile and need a monitor I can trust for color quality, because I can't make proofs here (in Europe).

Hal, Andrew, Web Weaver -
Thanks very much for your quick replies and advice. I was away from my computer
since my initial post so haven't had a chance to follow your advice yet. But I plan tonight.
WW: right, calibration is the correct term :) will look for the ICC file.
Hal, sounds like a worthwhile investment. Thx.
Andrew thanks for the link!
Will let y'all know how it goes.
Cheers
Bill

Setting Up a Color Correction Monitor

Sorry about the "rookie" question, but I am getting a little further along in my FCP editing skills, and now realize I need a monitor to do accurate color correction. I've seen plenty of monitors for sale on eBay, but I'm not certain how to hook the monitor up to my MacBookPro. Can someone enlighten me?

HD Plasma Televisions as a Color Correction Monitor

Hello All In MacNirvana,
I am working on a Powerbook 15" ( see specs below) and work with a lot of video editing with HD video. I am wondering if an HD or HD Plasma TV are suitable to use as monitors for color correction for film and TV when I edit in FCEHD.
And then I should also confim that I will be able to use the TV as a second display. I use a projector sometimes as a monitor by hooking a basic S cable up to the Pwrbk. I would think that this ( or maybe some other fancy cable combo ) would work well with a new HDTV.
I'm a real newbie to the HDTV thing, ( although I'm pretty handy with FCEHD, HD video and Compressor, etc....) so any answers should come in baby talk. Dumb it down for the kids sitting in back.
Thanks!
BBP/BR

It is generally a good idea to edit (or at least see the effects of your edits) on a TV vs. the computer monitor. I do this as well, but I am not sure it is being done properly by using a TV as a 2nd monitor (with a S video cable or the DVI out). With S video maybe with DVI you would be using a non-interlaced signal that should scan the entire width of the HDTV and this could be more than a TV viewable area.
I use a FW cable back to a DV camera (NB: a low cost DV camera is a lot less than a DV deck adn you can control it with FC) then connect the AV out to the TV. Since you want the work rendered to NTSC TV so it appears on the TV as it will look when played back.
You can do this as well with FInal Cut - the same DV camera you used to capture as it is already connected - just set FC to FW out and add a TV to the AV jacks on the DV camera.

Sony PVM 20N5U=Broadcast Color Correction Monitor?

Hello, folks. Posted this on the "Getting started with video production on a Mac" forum, but no responses . . . so I'm trying here.
I have a Sony 14M2U that IS indeed a professional grade broadcast monitor that can be used for color correction. However, I was recently given a Sony PVM 20N5U and I'm wondering if this one can also be used for broadcast standard/professional color correction. I looked online, but couldn't find any specific information on whether it was or not.
Any help resolving this would be greatly appreciated.
Thanks much in advance,
Javier

the n5u is a very sweet monitor and quite versatile. Beats the cr*p out of most of the lcd monitors out there. These are no longer in production, so check carefully the hours on the tube and the general condition.

Hooking a Sony Trinitron PVM-14N1U color correction monitor up to a Mac Pro

Hi, I recently acquired a monitor for color correction in Final Cut, and have no idea what cables/cards/external pieces I need to connect the monitor to my Mac Pro. Here is a link to a picture of the monitor's connections:
http://www.recycledgoods.com/zoom.aspx?productID=13654
If anyone could let me know what I need to do/use to connect this to a Mac Pro (newest model) I'd be much obliged. Thank you!

Thank you for your response. This now leads me to another question you can probably help me with. I already have two monitors on my Mac Pro, using both DVI slots on the computer's original graphics card. I'm planning on buying the ATI Radeon HD 3870 512MB graphics card, so to use a third monitor, should I keep the original graphics card on board and also install the new one? If not, can you tell me what the proper procedure would be? Thanks again!

Color Correction Monitor

I know this question has come up before, but after reading some posts I thought I'd see if anyone had any feedback on this monitor.
http://www.bhphotovideo.com/c/product/469728-REG/JVCDT_V24L1DU_DTV24L1DU_24_MultiFormat.html
It's the JVC DT-V24L1DU 24" Multi-Format LCD Monitor with 1080p Native Resolution and HD-SDI.
I've got a Kona LHe card with HD-SDI I/O.
Could I do critical color correction with that setup? I'm not at the stage where my color correction is critical yet, but I don't want to be re-buying anything if I don't have to.
Any suggestions?
Lawrence

This isn't an area of color correction per-say but involves general engineering of all the different video signals and how to mix them up and travel back and forth and what not.
Generally speaking, HD video is in a completely different color space than Analog/Digital video. itu-709 vs. itu-601. How are those conversions handled? Is the device you're using accurate? It's just one of the many bains of video engineers that care.
I've heard but not been able to confirm that some JVC hdv cams are in the itu-601 spec which if true would totally throw off how FCP handles color space conversion and the nearest I can tell that it does this is simply through frame size.
How are you monitoring currently? Aside from this monitor, what interface is spitting that video out of your computer? Currently at my house, I use an Aja Kona LHe that spits out component analog to my PVM-14M4U. When I am working with itu-709 video, is that on-the-fly video downconversion completely accurate? Without external scopes I couldn't tell you but I'm relying on the the trustworthiness and reputation of Aja products. I've installed and use many of their products in various facilities and I know them to be of excellent reputation.
As far as your colors being far off, you tell me? Who's your viewing audience, what sort of display are they watching, how's that signal getting there?
I'm hoping some of the more learned folks here can correct or corroborate any of the info I've related this morning.
Good luck, the water gets deeper and much colder very quickly the more you know.

My HD TV as NTSC Monitor for secondary color correction

Can I use my new Panasonic HD TV model TH-42PX80U as a NTSC monitor for secondary color correction using both Final Cut Pro out of a Macbook Pro intel? What cable I can use to conect via HDMI? Will the color acuracy will be similar to that of a NTSC color correction monitor? will my TV do a decent job for NTSC? THANK YOU FOR YOUR HELP!
I am not sure I have this HDMI cable to be use in my macbook pro does it comes with it?

Can I use my new Panasonic HD TV model TH-42PX80U as a NTSC monitor for secondary color correction using both Final Cut Pro out of a Macbook Pro intel?
Yes, but I would only trust it if you are going to be making DVDs, and ONLY if you properly set it up. I would not rely on it for broadcast color correction. The reason broadcast monitors exist is to have a standard...HDTVs don't have a standard. Go to best buy and look at all of them....none of them match. BUT, as a nice simple solution for DVD, I'd use it.
But the only way you are going to get a signal to it is with the Matrox MXO. It will do component to the monitor, or you can get a DVI to HDMI adapter...if you do that the MXO software will allow you to set the monitor up to color bars. That option is only available from of the DVI out of the box.
Will the color acuracy will be similar to that of a NTSC color correction monitor?
No...it would be similar to color correcting NTSC on your home television...because that it what it is.
will my TV do a decent job for NTSC?
I doubt it. Taking an SD image and blowing it up huge on this HD TV...scaled up. I wouldn't think so. I wouldn't use it for SD color correction.
I am not sure I have this HDMI cable to be use in my macbook pro does it comes with it?
You have a DVI port on your MacBook Pro. And they make DVI to HDMI cable adapters I'm sure.

Monitor for color correction

Hello guys,
I am a newbie to Color and Color Correction. I have a dual monitor setup with my Mac Pro.
I have two 24 inches of DELL 2408WFP & DELL 2407WFP. These monitors have different color, and I think it is just stupid how Dell manufactures them.
Anyways, From what I have learned, I know I am not suppose to do perform color correction for videos on any regular LCD monitors. Can you experts suggest me good color correction monitor? Not too expensive. I am not doing any major flim/music video or anything such. This is just a hobby of mine, and I'd like to learn new things as time goes on. Most of my videos are travel videos & I try to make a cinematography out of it. I also shoot landscapes.
I hope you guys can direct me right.
Thanks,
Lowell

I think there is a lot of snobery on this forum regarding hardware requirements. If you are not entertaining clients who have just come from a Da Vinci suite, then you CAN live with out a Broadcast monitor that meets EBU specs. The important thing is to use a video monitor and not a computer monitor. You will need a decklink like card to get the video into composite or component format, that later will give a cleaner image but most television is viewed in composite any way. Colorgrading is a matter of comparing the before and after image and comparing the graded shot with the pictures around it. The scopes will keep you informed of the limits and will help you interprit the monitor. Rember if the shot looks better after grading on a cheaper monitor then it will look better on a Grade A monitor with SDI inputs. Don't let the "big" boys put you off, and use the software that you own to inprove your video and your skill-set.
Good luck from Boaz

Color Correction for DVD and online

I have a 13" SD TV hooked up to my mac working as a color correction monitor for FCE.
My question is: Should I always color correct using the TV monitor vs looking at the Canvas in FCE? What I'm seeing is the picture in the canvas is darker and more saturated then the view of the TV monitor. Is it best to trust the TV monitor vs the canvas? And should it make any difference if the final project is going to DVD vs online? I'm assuming the ending product (mov file) should look the same if the mov file is viewed from a computer vs on a TV from a DVD. In a nut shell, once the clip is color corrected using the ext monitor, should I be good to go no matter where the file ends up?
Thoughts?
Thanks so much

Hi
I would take some photos with color miss match eg blue tint (Blå-Stick in Swedish)
and with other known color anomalities.
Put them in TimeLine and playback. View TV - corrected or as bad as from start.
I use a color corrected CRT-broad-cast monitor but prior to this a small TV and
this one did a good job.
Yours Bengt W

Color correction with a HD TV

I have to go back to the avid because they work on avid: adding titles, outputting to digibeta and so on
FCP does all this..there are hundreds of editors and facilities doing this daily, on broadcast television shows. I have been doing this for over 2 years.
As far as I know, there is compression-decompression going to tape and back even in fcp, so there IS a little loss.
Where did you hear that? It is incorrect. Outputting via a capture card to digibeta results in no quality loss whatsoever.
If you have an "official" source of information saying otherwise, please do let us know.
I looked at the AJA website and Decklink website and neither of them say that they compress-decompress upon output. If footage is captured via firewire, there is no quality loss, as was done on the Avid...and similarly with FCP. If you capture with a capture card as a different codec, it will compress it into that codec, but depending on the codec, there is little loss, nothing you'd notice. But Avid does the same thing, capturing to a different codec will result in unnoticable loss in quality. Outputting DV to digibeta...there will be a conversion to the digibeta format, that is unavoidable...on AVID as well as FCP. But again, unnoticable.
Can you point to an "official" Avid site that says there is no compression-decompression upon output?
the broadcast safe filter doesnt cut illegal blacks, cuts off only the values that are too high.
Uhm...where did you hear that? It cuts off the top and bottom. Although I don't rely on this solely...I color correct each clip until it falls within range, then add the Broadcast Safe filter, just in case.
FCP handles adding titles and outputting to digibeta, but then you'd need to invest in a capture card. But, since you are in DV land, why not output to a DV tape and then they capture that DV tape...that is a lossless transfer?

Color correction problems with multiple monitors

I just upgraded my Win 7 from RC to RTM. I then updated my color correction using Gretag Macbeth i1 for both adapters. My system has 2 video cards and 3 monitors. Monitor 1 runs off adapter 1, monitors 2 & 3 run off adapter 2. Both video cards and all 3 monitors are of the same model. I set adapter/monitor 1 to the ICC profile 1, and adapter 2/monitor 2&3 to ICC profile 2 from Gretag. Not running LR, everything looks as expected.
When I run LR on the primary monitor green leaves turn orange, if I had to guess I would say I'm loosing the green information. If I move LR to display 2 or 3 the colors are as they should be.
I ran into this once before and it was something simple to fix this, but I can't seem to find it now. BTW, this worked just fine before the upgrade from RC to RTM.

At first I thought a reboot cured the problem, but apparently not.

Image slow to refresh on HD monitor while color correcting

Hi, and Happy New Year, all!
We have an annoying issue, and wondered if anyone else had the same experience.
Our project is HD, ProRes 422, 23.98fps, working in FCS2, MacPro with a Kona LH card outputting to a Sony CRT HD monitor via SDI.
The issue is, that while color correcting, either moving from frame to frame, or grading a shot, the monitor sometimes refreshes straight away to display the change, but sometimes takes a second, and sometimes doesn't change at all. So, for example, if I bring the saturation of a shot all the way down, the preview window shows the change, but the monitor doesn't. This makes it very difficult to work out whether the changes are correct!
Anyone seen this happen?
thanks!
Matt

The video output is actually set to 10-bit 1080psf/29.97. Oddly enough, that was the only setting that would play smoothly out through an HDLink to an Apple 23" LCD, and the Sony CRT that we now have only accepts 29.97 anyway.
You think it's a frame rate conversion issue in the Kona? I see there are now v.5 drivers for the LHe - might see if they help any.
thanks
Matt
