AVS HD 709 - Blu-ray & MP4 Calibration - Page 64

Really the patterns here regarding flags are more centered around taking measurements from the screen. With a player that reacts differently depending on video flags, the behavior would be easier to notice by eye with the linked test clip. If you measured the screen, the patterns here might correspond with the linked test clip. From the WDTV link it seems that you're not measuring the screen, so in that case the differences with the AVS HD 709 patterns would probably be difficult to differentiate.

Based on prior discussions in this thread, different commercial Blu-rays may be either flagged or unflagged. On a quick glance it appears makeMKV retains the original video without any transcoding. If a player reacts differently depending on the flags, then all I can really suggest is transcoding the video to set the flags. I'm not familiar with different ways to necessarily do that. With x264 we used the following settings:

--colorprim bt709 --transfer bt709 --colormatrix bt709

No, despite the unfortunate usage of calibration to describe adjustment the AVS HD (and GetGray and THuffman's) disc is intended for calibration and requires a meter and software although there are patterns that can assist with adjusting by eye. The other discs vary a great deal in what they provide but none of them support calibration. They assist with adjustment.

A practiced individual with the right tools can make all the adjustments necessary to have a calibrated display using the AVS HD disc. That's not true of "DVE etc".

The more you can do, the better. But by far the biggest step you can take on your own is to spend $30-50 on a test disc, learn a little bit here about how to adjust basic settings, and align your display as best you can. Beyond that you need equipment, and progressively more expensive equipment and software depending on just how advanced you want to get and what the capabilities of your system are.

I refer you to a response that Chris Wiggles made, in another thread, regarding this very same argument: http://www.avsforum.com/avs-vb/showp...65&postcount=8. The key part is: "Trying to draw an arbitrary line about how much someone has to be able to do and achieve before it's "calibration" whereas something less is just futzing around as an end-user is not encouraging or helpful to anybody"

As for the full screen bars and ramps, one pattern for each, I think that is a reasonable request that shouldn't be too much work to add. We are going to probably give it a couple weeks before considering revising the disk, but I think that's doable. I figure having maybe twice the number of patterns that are in the Misc section right now is reasonable. So we will certainly take the suggestion into consideration.

Thanks for the feedback.

I can author a clip quick enough, so a video clip or two could be a quick turnaround. There might even be programs that can animate images, but I haven't looked much into it to see if that's the case or not.

Currently the ideas list is at http://www.avsforum.com/avs-vb/showt...5#post17167975 From my own perspective I like the idea of including a ChromaPure series patterns and maybe changing the APL pattern to flash black and white. Anyway, content contribution to the project would probably be the most likely way to see new content or changes.
