Thx Calibration Disc Download
AVSHD Calibration ScreenCalibration — adjusting the brightness, color, tint and other parameters of your TV — can be as much an art as a science. The free disc and files you can download from AVS Forums are excellent for basic calibration, although you need a meter to get anything close.
I've just run my TW3200 through with this as a precursor to doing a more thorough calibration. First impressions are its made a big difference and was a doddle to use. I was happy enough with my settings but they were way off. Things much improved now.As stated, though, it's not suitable for an in-depth calibration - its a more complex version of the free ones you get with THX discs but with a lot more patterns and a lot more things to play with. It will show areas that need improvement and will allow you to make 'by eye' adjustments of those areas. I was happy with the free ones on discs, but they're not as good as this one.
And this comes with the blue filters so you can have a go at setting the colours.I'll be selling mine on shortly - I've got an 'eye one' now and the Video Essentials disc so will be spending a few hours with that and doing a more hardcore calibration soon. If you're interested, let me know and I'll give you a heads up when I put it on my sales thread. It's mint and it'll be a few quid cheaper than amazon. I'd be very wary about using filters to accurately set certain image attributes. I've calibrated and compared the measured result to that achieved using different by eye colour filters. The result were significantly different in all cases.There are several factors that affect the use of filters such as the displays native colour gamut, display tech, the filter itself including degradation, source device, video signal format to be supported etc.There's no doubt that using the filter can make the resulting image 'look different' but it may not be accurately calibrated.Avi.

Hi guys!Having just installed my tw6000 in a dedicated av room with a 120' fixed screen i decided rather than pay £250 for someone to come and fiddle with the settings on my machine.i'd rather invest in calibration discs. I bought the cheaper one advertised on amazon for about £17 and it was a waste of time BUT the THX blu ray calibration disc, complete with blu tint glasses is truly an amazing product!though i was not far off from the ideal settings.the tweaks i made particulary with the tints and gamma settings was really awesome!
It definitely was worth just under £60.a friend of mine has offered to get hold of some more discs with glasses in the next few weeks. I wonder if any members of AVF would be interested in buying them. The best price i can do for those serious cinemaphiles is £47 including p&p recorded of course!if there is a demand i will get them sent over!cheersraj.
Convert fl studio files to mp3. Out of curiosity how do you calibrate colour temp (greyscale), gamma, colour gamut, colour luminance etc using just your calibration disc?The free to download AVS HD 709 (link in post #2) contains appropriate HD material to fully calibrate most displays. Just burn to a normal DVD or Blu-ray.
Here's what's covered -I wouldn't waste money on other calibration titles to calibrate display chain basics which in reality is all that can be achieved without appropriate tools/range of adjustments etc.A useful intro to calibration info can be found here -Avi. Dynamic range low and high is simply showing you single increment interface steps to allow you to assess performance.
Pinnacle Dazzle Hw-set DVC 100 Rev 1.1 DVD Recorder Video Capture Device USB. Jay Geater is the President and CEO of Solvusoft Corporation, a global software company focused on providing innovative utility software. If it does, then the Pinnacle drivers are not loading properly. All the drivers for the supported hardware install automatically when you install the Studio software. The DVC is listed below as an example. This was a Pinnacle hw-set dvc100 rev 1.1 price-efficient solution, instead of buying a completely new set. Pinnacle dazzle drivers.
It's an assesment pattern that will reflect the impact of how you set brightness and contrast.For example if you've set brightness level correctly dynamic range low provides a visual indication of near ref black performance (in ideal viewing conditions). Interface code 16 is ref black and should merge with the background with flashing 17 being barely visible and flashing 18,19,20.
Etc increasing in luminance gradually.Dynamic range high does a similar thing for near ref white (code 235). Depending on your calibration goal/system capability the pattern allows assessment all the way to interface code 254.There really isn't much beyond brightness and contrast you can 'properly' set in terms of accurate calibration by eye.Some of the by eye assessment patterns such as chroma multi-burst/chroma zone plate can help establish if there is an optimum colour space i.e. YCbCr 4:2:2, YCbCr 4:4:4 or RGB (video) output setting for your combination of source/display products.You may be unable to adjust some of the specifics the different patterns allow you to assess but this should provide some idea of how various aspects of your system performs.Avi.

I WILL have a look at these later today.I guess video calibration is a very complicated affair, if you decide to use fancy software on a PC.however the THX disc allows the uninitiated novice, who still appreciates 1st class results to get as good as he/she can without resorting to vast expense and time. I forgot to mention it also calibrates audio set up 7.1.My projector cost £1300 (tw6000 epson) so on a budget spending another £200 to tweak my settings would significantly increase the initial outlay and i firmly believe the disc and tinted glasses is a worthy spend for a layman like me!! But if you have the money.then sure go get a professional but then i'm also sure you will most probably also have bought a far more expensive PJ than mine!!!;-). Thanks for the links Avi.

If you really are interesting in buying a disc, and learning a bit about calibration I can recommend Disney WOW. It is an interesting any informative disc (although the movie clips are a bit poor - mostly animation).I do agree with AVI though, you can only set the basics with a disc, and there can be a lot of variation in those 'blue' glasses that are supplied.I carry a lot of test discs when I do a calibration (along with a pattern generator and all the other equipment), including the AVS disc, and spears and munsil.As for £200 being too much when compared to a £1,300 projector. I have calibrated a number of panels/projectors that retail at the same or lower value. Resurrecting this thread with a question.I've never calibrated a display before but will soon take delivery of a JVC DLA-X30 projector that I would like to calibrate. As it turns out I do a fair amount of digital photography and purchased an Eye-One Pro about 8 years ago and have calibrated displays and printers (although never a projector). I've got about 6 tripods as well.So.looking through Curt Palme's very helpful looking guide for calibration for dummies I seem to have all that I need apart from a test disc.
He recommends the DVE HD Basics disc but unless I have missed something in his guide all that seems to be needed from there are the 0-100 IRE steps to calibrate grey scale. The above linked AVS HD data is free and according to the patterns manual has these grey scale patches, although I am not sure how big they display at when projected. I may be reading things wrongly on the AVS HD patterns manual but it seems to suggest there is a 5,9, 10, or 11 step grayscale that would presumably show a range of IRE patterns. Although I do see something in the table of contents talking about 10% greyscale which may be separate swatches of IRE at 10% increments.In any event, my question is may I use my Eye One Pro, tripod, and the AVS HD 709 data burnt to a DVD to calibrate my new projector and still follow Curt Palme's guide, or should I be going some other route?Thanks for some guidance and apologies if its a silly question - but this is a new area for me.Best,Dave M. Don't see why not,assuming that the eye one is still calibrated.
I did my RS45 with my i1LT at the weekend using the free disc, it's all you need.There are both windowed and full-screen greyscale patterns from 0 to 109% in 10% increments on that disc (in the ColorHCFR chapter), I'm not sure it matters which you use (probably depends on how big your screen is). Start with the brightness and contrast controls first, though, using patterns 1 and 3 in Basic Settings.Note that you can't adjust the color gamut except in a crude manor by using the color and tint controls (unless you have an external processor). There are also only 2 greyscale correction options, gain and offset, from memory, but just using these still gives a good result.If you want to go further there is multi-point white/r/g/b gamma control which also corrects the greyscale, so you should be able to get a very accurate greyscale and gamma if you go on for long enough. Some people have claimed this causes posterization, I haven't noticed any myself.I also used gamma 2.5, this seemed closest to giving me 2.2 to start with.Big thread on this on the avsforum. Thanks man - 5 pages was a quick read and indeed very relevant for me.It seems that Calman (which I may buy) or the HCFR software both internally have some kind of step by step guide so I still haven't figured out if the AVS downloadable disc is even necessary or if IRE swatches etc.
Are part of the Calman or HCFR softwares but either way it looks as if I should be able to stumble through the requisite learning curve and get the X30 calibrated once it is delivered and out of the box.Thanks again,Dave.
