AVS HD 709 - Blu-ray & MP4 Calibration - Page 62

Try http://www.imgburn.com/. People seem to have better luck with it for burning iso files.

Downloaded ImgBurn and not long later I have a working calibration disc loaded up in my BR and working!!

Thanks so much 'Alluringreality' and 'Wmcclain' !!!

Thanks for the disc!! It's been amazing so far and the burning worked like a charm. I'm using the PATCHED disc on a DVD on my JVC XV BP1.

Question on making some of the finer color adjustments. I found pattern A6 to be very helpful for adjusting RGB-offset. Now I'm trying to adjust the RGB-Gain, and I'm wondering if I should I be using pattern A3 to adjust specific white balance settings, or if it wasn't intended for this? My reds on this pattern are all blending together from 232-235 when I have my R-gain set on the TV default of 25. To get the high reds to differentiate, I need to turn R-gain all the way down to 0. Seems like an extreme adjustment...do I not want to mess with this? Blues are also blending for the top 2-3 bars. Also, for pattern A7 I can pretty much see NO BARS at all for red and blue at my contrast level...they come out if I turn the contrast down a bit, but this is not the best contrast as calibrated according to whites. Green looks ok from 229-235. (Just to provide full info, WTWs are all getting clipped for me in basic pattern 3 regardless of the contrast setting. Not sure if it's the blu ray player JVC XV BP1 or TV Samsung LN46A650. But the contrast looks good otherwise in the patterns from deep black to bright white, and I'm not too concerned about the WTWs. I'm using YCbCr on the blu ray player, because it seems that is the way the movies are authored onto the discs anyway.).

So do I need a red filter or a meter or something to be even messing with these kinds of controls, or can I use these patterns and my eyes? My TV has a built in blue filter only.

Any feedback is greatly appreciated. :-)

Grayscale adjustments require a meter or at least an optical comparator. What you're doing is NOT correct. BTW, color filters are for setting color and tint only.

OK, so for someone without a meter I guess the best thing to do it just leave specific white balance controls alone. Oh well.

I also had a question about gamma. Didn't see a gamma pattern on AVSHD, but I was calibrating gamma using an Avia DVD and my "Ratatouille" BD also has a test pattern. CNET's posted calibration settings for my TV had gamma set at +3, but when I do the "squint test" I'm getting -2. Any reason for the big difference? Should I be trusting my eyes on this one? I'm absolutely positive that -2 makes all of the grays blend best on the pattern. I guess it's a matter of preference, regarding having accurate reproduction vs. extra shadow detail?

Hi everyone I hope someone can help me, On A2-Grayscale steps should the 2 brighter than white bars be the same, blend together like the blacker than black do or should they also be distinguished from each other. This is on a Panasonic Plasma and when I blend the whiter than white together I get a contrast of 80 from a default setting of 50 is this okay? any help would be appreciated.

Cheers Bob

I liked the tools provided thanks!

But I have a problem setting geometry using the standard patterns. What seems to look good on a pattern ends up showing a distortion on the screen somewhere during a motion scene.

I'm sure it's my eyes that are the problem, but would it be possible to make a different pattern/s for geometry that might make it easier to spot problems? Something like a series of parallel lines that move left to right/right to left, and then a set that moves up/down? It just seems that it would work better.

Hi everyone!

First of all thanks to the creators of this project for the magnificent work. I've read most of the thread and I'm really impressed by the amount of work involved and the tremendous support to all users, novice and experts alike.

I've recently downloaded AVCHD v1.3b and burned using imgburn (not without problems due to crappy DVDs).

Using the basic patterns, I've managed to set the greyscale settings of my lcd as accurate as possible, tweaking contrast, brightness & sharpness. I do not have color filters or other advanced equipment yet, so I set color matching the recommended settings from reviews and seems Ok.

Nevertheless, I have a question regarding 'RGB Low Level' pattern. With the current Brightness setting, Grey clips with black at 16, but Green and Blue clip at 18 and Red at 22. Is this Ok although this apparently means I'm loosing details in low Reds?

It doesn't seem there is much I can do to make the three colors clip at the same level without affecting the whole picture quality.

Thanks in advance.

Guys, i just found this forum and i am little confused with the AVS disk. I burnt the iso file to the BR player and am trying to play. Its giving me instructions to adjust the black color where its flashing to some reference point. Should i adjust the service menu offsets or the picture setting on the menu. Is there a step by step guide ? Thanks a million.

I can't seem to download the HDDVD manual pdf. (I can download all of the others though). Is the link to the HDDVD manual corrupted somehow?

I cannot get the HDDVD version of AVS HD709 to play on my player. I have a HD-A30 with the most recent firmware. It tells me that the "this disc is not DVD format. Cannot pay the disc." Any suggetions besides buy a blu ray? Thanks!

Would it be possible to get lower res mp4's that are compatible with the Apple TV? It only supports up to 1280x720 h.264, as far as I can tell.

Or, does someone have a way to convert them? Handbrake wouldn't work for me.

iTunes will do that for you. Naturally any resolution patterns are corrupted.

bodosom- thanks for the reply. I did not know that, but I figured out how, and it couldn't be simpler.

Just select the video, then go to "Advanced", then "Create Apple TV Version"

Thanks again!

Edit: It looks like it created 1280x720 versions of the files, but they just result in a white screen. Not sure what is going on. I'm doing this on a WinXP PC, if that makes any difference.

I tried a day later to download the HD DVD .pdf and had no problems...

I played with the "basic settings" this morning and I like this MUCH better than the THX Optimizer... especially setting tint/color.

A hearty "thank you" to those who put this disc together!

Hello,

I have encountered a troubling problem when calibrating a new LED-backlit tv with both GetGray and the AVS HD 709 disc (using AVCHD on a Panasonic BD). After completing my calibration with AVS HD, I get results for my Color setting that say my 75% red-to-white Y ratio is near perfect: .213xxx. But then when I use GetGray and take readings with the exact same probe (a modified Chroma 5) on the exact same player with the exact same settings, I get a result of just below .20. Can anyone clue me in to what in the world is happening, here? I am at a loss. Is this resulting from a faulty conversion in the player, or something?? My BluRay player will not read the HCFR patterns disc, so I cannot compare its results to GetGray's to triangulate the problem. Has anyone else encountered this discrepancy? Can anyone help me figure out where the problem is and/or how to fix it?

Thank you in advance for any hints or advice you have.

Anyone?

I have an issue, my LCD monitor is calibrated to the .mp4 17 reference black level in MPC-HC with DXVA decoding however when I watch HD .mkv movies there are no absolute blacks outside of credit screens.

Both instances it is DXVA's H. 264 decoder so it shouldn't vary, you cannot adjust anything on the player picture wise when DXVA is decoding.

cant wait to try out avshd,spent the better part of well over an hour downloading everything i needed( roxio) wouldnt burn for some reason,looks like a lot of reading to fully understand patterns & such"will have to substitute "coffee for beer" for that,but the disc came out fine,thanx to all who put this together,maybe one day i can actually sit down & enjoy a flick instead of constantly tweaking or reading up on forums to get the best out of my panny viera,will post after tweaking again.: jb

Does the flashing color bars pattern under basic settings use 75% or 100% color and if it uses 100% color is there a 75% alternative available on the AVS disc for setting color/tint with a blue-only mode/blue filter?
