AVS HD 709 - Blu-ray & MP4 Calibration - Page 68

I took a look at the site and there's no mention of AVCHD, so I suppose the patching could be cause of the stopped playback with the Patched version. Actually the other Magnavox (Funai) was also reported as playing HDMV on DVD, but to try to keep things as simple as possible that hasn't been explained on the main page. Anyway, thanks for the feedback.

If the player will play rewritable media, then yes it's fine. For example, BD-RE (rewritable) would generally be recommended for Blu-ray media.

For the first pattern at the screen is fine. For the second pattern you should probably be able to see somewhere in the range of 19-21 begin flashing from your seating position. On my display if I set the first pattern at the screen I can also see somewhere around 19 and up flash on the second pattern. If that isn't the case, you might want to choose the higher setting between using the first or second pattern.

There's not much difference aside from the authoring. The HDMV would be the recommended choice if you can use any version, but generally similar video playback is expected with standalone players regardless of the version.

Getting the APL pattern to flash somewhere in the range of 19-21 and up is probably going to be somewhat similar to the sort of brightness setting you would get with a commercial disc such as Digital Video Essentials. Displays can vary with APL, so the first brightness pattern will not work on all displays. If the first and second basic settings patterns differ significantly, then probably go with the higher brightness setting.

The sharpness pattern is meant to have one solid shade next to another solid shade. The transition between the shades of gray should be as clean as possible, with one shade of gray right next to another shade of gray. On some displays if you turn sharpness all the way up you will cause what could be described as ghosts, echos, or ringing at the edges between the shades of gray. So if sharpness is too high you might get lighter outlines near the edges, instead of one solid color next to another solid color. The main point of the sharpness pattern is just to try to eliminate the negative effects (mainly lighter edges) of having sharpness set too high.

The AVCHD or Patched versions are intended for DVD burners and should work with the PS3. http://www.steekr.com/n/50-17/share/...4b550dcc18ceb/ is an alternate download site. For some reason the steekr link currently seems to be locking up Chrome, but it still worked in IE when I tried it.

There really is not a one size fits all answer for contrast, and either may be acceptable. Showing all levels above white would probably be the text book recommendation, but one downside of showing all above white levels is that white will not be as bright. On the other hand a downside of showing no levels above white is that there's more chance of color shift near white. If your display can cut-off above whites, choosing a middle-ground of displaying a few levels above white would be the way I'd probably go in terms of giving any broad recommendation.

Seeing pink would be what I called color shift. At the 21 setting if you see pink then you need to turn down contrast, because you do not want 230-235 showing pink. Turning down contrast will cause any color shift toward pink to happen at higher video levels, and you want to try to keep any shift toward pink above white (235). Using the contrast setting of 13 would probably be a generally safe setting where 230-235 will not have much color shift. If you want to go higher than 13, to have brighter whites, just try to limit any color shift near white. The Grayscale Ramp pattern from the Misc Patterns can also be used to look at any shift toward pink near white.
