|
|
Hi,
I once had all the testpatterns (resolution, sharpness, greyscale etc), but I can't find them anymore.
I've been searching various forums and with google, but I can't find any.
Can someone upload some test patterns or give me a link where I can download them?
Thanks,
Tillman

PC. So a simple jpeg would do.

I for one would like to see someone put out a Blu-Ray disk of nothing but test patterns. Any audio content would only be a guide to the usage of the test patterns. Very basic, no frills, not "educational" but an actual UTILITY disk.
Of course it should contain many test patterns, not just a few. Each of them should have a definite purpose.
It would be best if it was done using the interactive menus like the simple games that are on some BRDs.

How about the AVS HD 709 image?
http://www.avsforum.com/avs-vb/showthread.php?t=948496
| Quote: | INTRODUCTION
This project aims to provide a free set of calibration patterns for high definition (HD) video players. You will find downloads here to create discs for Blu-ray and HD DVD players, a version with MP4 1080p video for computers or other compatible devices, and PDF manuals with basic information about the patterns. The Blu-ray and HD DVD discs can be burned to DVD media, but they are intended only for HD players. These calibration patterns are not intended for standard DVD players, and they are not expected to calibrate for Rec. 601 video used in commercial DVDs. The AVS HD 709 patterns are meant only to calibrate for Rec. 709 encoded HD video, such as commercial Blu-rays or HD DVDs.
Our primary intent is to offer HD video patterns for calibrating digital displays (LCD, Plasma, DLP, D-ILA, SXRD). That means there are no audio portions or patterns specifically meant for analog TVs (CRT), which can be found on other sources such as Digital Video Essentials and Avia. The patterns provided here have simply been divided into sections for different tasks, and each section is made up of a number of video patterns. The Blu-ray and HD DVD discs allow you to select sections from the menus, and the video clips in each section can be navigated by chapter skipping. The Basic Settings and Miscellaneous Patterns sections are intended to be useful in setting user controls for your electronics with no test equipment, except possibly a color filter. The remaining sections are meant for taking measurements from the display, with a colorimeter or spectroradiometer, using software like ColorHCFR or CalMAN. The Related Links area of this post will take you to more information about measurements, and further details about using the patterns are covered in the attached PDF files.

didn't Sony used to supply test patterns on BD discs? They were not on the menu but could be accessed by entering a code at the correct time.

Yes. It's 7669-enter at the title menu, but there are only 4 patterns I believe. Haven't tried it in a long time, so I don't know if they're doing it on new titles.
I've been thinking about building a very comprehensive test pattern library in multiple resolutions and aspect ratios (think 720p, 1080p, and both 1.78 and 2.40) and publishing it in multiple formats like the AVS 709 disc, but it would be a LOT of work. With my all my other projects, I can't justify doing it for nothing, but I have a feeling nobody would really be interested in paying for it, either. I wouldn't be talking $20 like a test pattern disc - more like $10 or something relatively token in nature - mostly just to placate my wife - she's much more agreeable to me spending time away from her and the family to work on things when there's profit involved - even if it's not a lot of profit... But, I don't know that anybody would really be interested even at that price. Anybody have an opinion on that?

Sounds like a noble effort, but with the sources like AVS709 available, why bother?

I agree, as Stacey has a really good disc as well for $25 (or free if you buy an Oppo). It does look like it was and is a lot of work.

Now that there is 4k coming along, Stacey mentioned including some of these patterns as well. He bought a Red camera and said he is itching to use it.

Could you go on-line with a PS3 and download it directly to it's HD?

Yeah... That's what I was getting at. But, AVS HD 709 is missing some things, is only video-based (no still images), has no 720p- or scope-specific patterns to speak of. I was thinking of something along the lines of a test pattern disk for us CRT'ers first, and everybody else second. Maybe not with the depth of the AVS HD or Spearks disc, but more breadth and the flexibility of lots of different resolutions and aspects (for 1:1), and still images for easy playback on lots of different devices besides HTPC or Blu-ray player.
But, yeah - you're probably right.

No, you have to download it to a PC, unpack it, then either stream it, or make a disc or put it on a Flash drive to copy it to the PS3.

I'm currently using a mix of AVS HD 709 and some static 1080p updated versions of the old (pre and post) NTSC Indian. Pretty cool!
I too am streaming from the PS3 but to make adjustments you have to pause the image (if using AVS HD-709), which leaves the pause indicator at the bottom of the screen. I'm sure I speak with everybody else in mind when I say that I am extremely hinky about any static images like that. The Indian patterns are static (png) too but I have vertical adjusted oversize while doing a rough physical install of the pj and screen.
I thought of cranking out a menu'd DVD with BR HD patterns and wondered if there would be a call for them also. To answer that question I challenge anyone to just TRY and find a good source for calibration quality software patterns at rates we use and need...they're far and between; free ones anyway.
The crowds outside the US/Canada have gads of them but they're PAL or computer resolutions...or not optimized for CRT pj's in general. Meaning, they capture them with light cannons or flat panels in mind and are too dim for anything but the highest end or stacked CRT pj configurations.
Making them as bright as newer technology requires increasing G2 and B&C and could introduce a myriad of issues that would negate any benefits of the pattern. (flaring, shifting, etc). The undesired but beneficial (if you squint real hard) side effects would be informative in that they suggest the need for circuit updates (caps, resistors, switching diodes, opamps, etc) but isn't practical for pj's that display all rates just fine at optimal settings.
An interesting thing I found while doing a quickie research: http://en.wikipedia.org/wiki/Comparison_of_display_technology
Apparently CRT pj's are still considered to be good only for TV's or presentations. 
I'd buy a pattern disc for sure. Not that I can't drag and drop to build one for myself....I'm just lazy.
