Bad pixelation when ripping a DVD

Hi,
I have a series of four DVDs I bought for my wife at Christmas. I have been using acidrip to rip them to my Hard drive as a series of AVIs and then I convert the AVIs to MP4s to put them on her Ipod. Each DVD has around 9 episodes of a TV show. All the episodes on DVD's 1, 2 and 4 worked no problem. Four of the episodes on DVD 3 are useless because of a really bad picture. (I've heard similar problems on fibre=optic TV being called pixelation). The settings I used for acidrip are as loaded by Pacman, the defaults.
It's the AVI's that have the problem. Converting a bad episode to MP4 doesn't help.
What settings can I change to resolve my problem. The episodes play fine over a regular TV so I know that the issues is something to do with the way acidrip is set up.
Any and all help or suggestions appreciated!!!
Thanks.

i had some serious trouble ripping some copy protected dvds directly (without reencoding the content) to my harddrive. i'm usually using
mplayer dvd:// -dvd-device /dev/scd0 -dumpstream -dumpfile dvd.vob
and in most cases this just works, but with some (probably copy protected) dvds i end up having pixel-salad (i dont know it that's what you're calling pixelation).
i found out, that to circumvent this problem (allowing mplayer a proper usage of libdvdread and libdvdcss) you need to unmount the dvd first.
try to rip the dvd with mplayer using the way i've posted above and make sure you have the dvd unmounted first. in case the result is still pixelated, i'm just out of clues.
i don't know if this helps you, but as nobody else seems to have an idea i just wanted to have it posted.

Does anyone experienced bad quality when burning a DVD?

Does anyone experienced bad quality when burning a DVD?
Using OS 10.6.8 and Magiv Video in iDVD, I am having a hard time creating a decent DVD. The videos per se are fine, but the intro menu and menu text and images are extremely poor quality and hard to read. What is going on?

Hi my notes on this - might be of help
DVD quality
1. iDVD 08, 09 & 11 has three levels of qualities. (version 7.0.1, 7,0.4 & 7.1.1)
iDVD 6 has the two last ones
• Professional Quality
(movies + menus up to 120 min.) - BEST (but not always for short movies e.g. up to 45 minutes in total)
• Best Performances
(movies + menus less than 60 min.) - High quality on final DVD (Can be best for short movies)
• High Quality (in iDVD08 or 09) / Best Quality (in iDVD6)
(movies + menus up to 120 min.) - slightly lower quality than above
About double on DL DVDs.
2. Video from
• FCE/P - Export out as full quality QuickTime.mov (not self-containing, no conversion)
• iMovie x-6 - Don't use ”Share/Export to iDVD” = destructive even to movie project and especially so
when the movie includes photos and the Ken Burns effect NOT is used. Instead just drop or import the iMovie movie project icon (with a Star on it) into iDVD theme window.
• iMovie’08 or 09 or 11 are not meant to go to iDVD. Go via Media Browser and as Large (NOT HD or other resolutiona as result will suffer) or rather use iMovie HD 6 from start.
3. I use Roxio Toast™ to make an as slow burn as possibly e.g. x4 or x1 (in iDVD’08 or 09 this can also be set)
This can also be done with Apple’s Disk Utilities application when burning from a DiskImage.
4. There has to be about or more than 25Gb free space on internal (start-up) hard disk. iDVD can't
use an external one as scratch disk (if it is not start-up disc). For SD-Video - if HD-material is used I guess that 4 to 5 times more would do.
5. I use Verbatim ( also recommended by many - Taiyo Yuden DVDs - I can’t get hold of it to test )
6. I use DVD-R (no +R or +/-RW) - DVD-R play’s on more and older DVD-Players
7. Keep NTSC to NTSC - or - PAL to PAL when going from iMovie to iDVD
(I use JES_Deinterlacer to keep frame per sec. same from editing to the Video-DVD result.)
8. Don’t burn more than three DVDs at a time - but let the laser cool off for a while before next batch.
iDVD quality also depends on.
• DVD is a standard in it self. It is Standard Definition Quality = Same as on old CRT-TV sets and can not
deliver anything better that this.
HD-DVD was a short-lived standard and it was only a few Toshiba DVD-players that could playback.
These DVDs could be made in DVD-Studio Pro. But they don’t playback on any other standard DVD-Player.
Blu-Ray / BD can be coded onto DVDs but limited in time to - about 20-30 minutes and then need
_ Roxio Toast™ 10 Pro incl. BD-component
_ BD disks and burner if full length movies are to be stored
_ BD-Player or PlayStation3 - to be able to playback
The BD-encoded DVDs can be play-backed IF Mac also have Roxio DVD-player tool. Not on any standard Mac or DVD-player
Full BD-disks needs a BD-player (in Mac) as they need blue-laser to be read. No red-laser can do this.
• HOW much free space is there on Your internal (start-up) hard disk. Go for approx. 25Gb.
less than 5Gb and Your result will most probably not play.
• How it was recorded - Tripod vs Handheld Camera. A stable picture will give a much higher quality
• Audio is most often more critical than picture. Bad audio and with dropouts usually results in a non-viewed movie.
• Use of Video-editor. iMovie’08 or 09 or 11 are not the tools for DVD-production. They discard every second line resulting in a close to VHS-tape quality.
iMovie 1 to HD6 and FinalCut any version delivers same quality as Camera record in = 100% to iDVD
• What kind of movie project You drop into it. MPEG4 seems to be a bad choice.
other strange formats are .avi, .wmv, .flash etc. Convert to streamingDV first
Also audio formats matters. I use only .aiff or from miniDV tape Camera 16-bit
strange formats often problematic are .avi, .wmv, audio from iTunes, .mp3 etc
Convert to .aiff first and use this in movie project
• What kind of standard - NTSC movie and NTSC DVD or PAL to PAL - no mix.
(If You need to change to do a NTSC DVD from PAL material let JES_Deinterlacer_3.2.2 do the conversion)
(Dropping a PAL movie into a NTSC iDVD project
(US) NTSC DVDs most often are playable in EU
(EU) PAL DVDs most often needs to be converted to play in US
UNLESS. They are play-backed by a Mac - then You need not to care
• What kind of DVDs You are using. I use Verbatim DVD-R (this brand AND no +R or +/-RW)
• How You encode and burn it. Two settings prior iDVD’08 or 09
Pro Quality (only in iDVD 08 & 09)
Best / High Quality (not always - most often not)
Best / High Performances (most often my choice before Pro Quality)
1. go to iDVD pref. menu and select tab far right and set burn speed to x1 (less errors = plays better) - only in iDVD 08 & 09
(x4 by some and may be even better)
2. Project info. Select Professional Encoding - only in iDVD 08 & 09.
Region codes.
iDVD - only burn Region = 0 - meaning - DVDs are playable everywhere
DVD Studio pro can set Region codes.
1 = US
2 = EU

What it turned out to be was the "quality" settings in iDVD. The total clip time was NOT over 2 hours or 4.7GB, yet iDVD created massive visual artifacts on the "professional quality" setting.
I switched the settings to "high quality" which solved the problem. According iDVD help, "high quality" determines the best bit rate for the clips you have.
I have NEVER seen iDVD do this before, especially when I was under the 2 hour and 4.7GB limits.
For anyone else, there seem to be 2 places in iDVD to set quality settings, the first is under "preferences" and the second under "project info." They do NOT seem to be linked (i.e. if you change one, the other is NOT changed). take care, Mario
TO GET IT TO WORK SLIGHTLY FASTER
• Minimum of 25Gb free space on Start-Up hard disk
• No other programs running in BackGround e.g. Energy-Saver
• Don’t let HD spin down or be turned off (in Energy-Save)
• Move hard disks that are not to be used to Trash - To be disconnected/turned off
• Goto Spotlight and set the rest of them under Integrity (not to be scanned)
• Set screen-saver to a folder without any photo - then make an active corner (up right for me) and set
pointer to this - turns on screen saver - to show that it has nothing to show

Moving/vibrating background pixels when watching a DVD

Ive noticed when watching a DVD (its the only video test ive run), that there is all this "noise" in background, or on still objects (say it curtain). it looks as though very tiny pixels vibrating alot. (they are whatever colour the environment is), so its basically just distortion of whatever im looking at. they move really really fast. Is this normal? I expected the picture to be sharp and crystl clear.

Just from looking at your picture I would say it is a "film grain".
Most feature movies are shot on wet film, not digital and the noise is natural.
A lot of movies shot in HD are post-processed to add the film grain, just to make them look more natural. In short, not seeing any pixelation or colour banding in your shot - this is exactly what the DOP had in mind - film grain.

When ripping a DVD, is the original DVD damaged (using Disk Utility)?

A friend wants me to make copies of a couple DVDs of her new baby to send to family, but she's keeping the original DVD for herself. Before I use Disk Utility to burn it to a new disc (using the "New Image" method), I wanted to make sure the original copy will not be damaged in any way. After I rip it, the disc will play normally when she puts it in her computer/dvd player, right?
I apologize if this is not the correct community or something--I wasnt quite sure where it fit in.

It’ll remain as is.

If i capture in imovie, it looks great. But not in fcp.
I have setup the captur settings to

When i capture and press esc to stop it says.
The audio sample rate of one or more of your captured media files does not match the sample rate on your source tape ????

Have you checked your capture settings and where are you viewing your footage? You should be looking at it on an external monitor or tv.

Bad pixels on iPhone when playing video

Hi! I have just purchased the iphone and am facing a peculiar problem. When I play video in either youtube or Safari (quicktime), after a while, the video quality deteriorates, i.e. a lot of bad, discoloured pixels start appearing. And this only happens with video playback. The discolouration does not appear if I switch to viewing photos etc.
Is this a common problem? Is it related to the iPhone overheating? Should I go to the iStore and get my phone replaced?
Would appreciate any thoughts/answers.
Thank you!
jd2334

I've had issues with stuck pixels and The Apple Store agreed for an exchange. Using your iPhone, point your Safari browser to this site to check for bad pixels: http://www.ebaspace.com/iphone-app/#_home
That's the sure way of finding out. And if you have it, just go back to your local Apple Store and use the same website to show the person from the Genius Bar.

Bad quality playback when burnt to DVD

Hey,
I have burnt my imovie project using the share - media browser in imovie and then the professional setting in idvd. When I play it on my new sony dvd/bluray player on my full hd tv with HDMI lead it has very poor playback. The sound is very muffled and the picture is slighty jumpy.
However when I played the dvd in my parents old dvd player still running off a scart lead but again an hd tv it was perfectly fine with great sound. Can anyone explain why this is and how I might achive a good picture and sound quality in my dvd/bluray player?
Thanks!

Hi
I think there is one more thing to this.
• Your parents DVD-player most probably has a superior picture correcting chip in it
BUT
iMovie'08 or 09 or 11 - are not the tool to use when wanting a DVD in as good quality
as DVD can be (SD-video as old TVs)
Due to that they discard every second line resulting in a less sharp picture.
I use
• iMovie HD6 - or - (But do not use "Share/Export to iDVD" - only directly import into iDVD
from within iDVD ! )
• FinalCut (any version) - or -
• FotoMagico™
They all delivers maximum to iDVD
Other thing I do
• Secure a minimum of 25Gb free space on Start-up (Mac OS) hard disk
• Use good DVDs - I use Verbatim
• DVD-R
• Burn speed set down to x4 or x1
• Pro Quality encoding

PE11 Rip from DVD- putting a menu on- burning that to DVD ruins quality

First, I've read some things here and there, but can't find the exact same scenarios in other posts, although I'm sure this is a fairly common problem (SIAP):
Here is a summary of the issue:
1) Our guy produced a video for our organization and gave me a DVD-R of the 11 minute project. I imported this into PE11 and on the timeline it says .VOB. Now on the desktop, the 481 mb VTS_01_1 file properties state that it is 720x480, 29 fps... although I find it strange that the clip as imported into PE11 in properties in the project assets window says it's 23.976 frame rate. Making things more confusing (don't even know if any of this matters) is that in an instance of Share->Export to Computer, the "source" says the video is 1920x1080, 29.97 fps. Don't know if any of this matters...
2) Anyways, the reason I ripped it is for the sole purpose of creating a menu on the DVD. So I picked a "HD" template, imported my own JPEG on to it, then attempted as best I could to erase all the buttons except for "Play Movie." AGain, not sure if the Menu functionality has anything to do with the issue, but I figured I'd mention it.
3) I've tried several times burning the video with both DVD-R and +R using both NTSC Dolby and Widescreen Dolby to burn to DVD.
The resulting DVD has a degraded, fuzzy image and the black frame lines at bottom and top seem to bounce and jitter.
The image on the original DVD is clearly HD and looks great, without any bouncing, jittering, etc. Also, the DVD app i used to watch the original on my computer is the same as I used to watch my own burned DVD... So PE11 has clearly degraded the image, something is going on in the export.
Another thing worth mentioning is that as I look at the video footage in PE11 on full screen, I can see that even in PE11, the video quality is not the same as the original DVD and there are obvious artifacts and just nonsense in the picture... Not necessarily as bad as the burn, but similar.
I've done a little reading on these forums about .VOB files... I don't fully understand them. Is it that the image is messed up from the beginning with an import from DVD? IS there a way to do what I want (take hiqual video from a DVD, put a menu on it, then burn it back onto DVD?) with PE11? Or is the only way to make a burn from the original source file before it was burned the first place?

Please get a MediaInfo readout of your VOB at the onset to determine what you have, especially standard or widescreen.
http://mediainfo.sourceforge.net/en
Special Interest: Frame size, Frame rate, Display 4:3 or 16:9, Scan Type and Scan Order for which I am expecting Interlaced and Lower Field First.
Here is my take on your situation.
1. The Canon 6D can capture 1080p video (1920 x 1080 16:9 at 29.97 or 30 frames per second), but from what you wrote somewhere along the line someone put that through a video "authoring" program to convert it into DVD-VIDEO format on a DVD disc (720 x 480). At this point, we need to know standard or widescreen. Both standard and widescreen will be 720 x 480, but the widescreen will have a 16:9 flag included to stretch the video for display after encoding.
Question:
a. What is on that DVD disc....just a file name VTS_01_1 (file size 481 MB) or two folders named OpenDVD and VIDEO_TS? If you have a file, for Premiere Elements 11, you would use Add Media/Files and Folders to get the file in Project Assets. If you have the DVD disc in the DVD burner tray, you would use Add Media/DVD Camera or Computer Drive to rip the VOB and get the VOB into the project.
b.Your project is going to get messed up and confusing, if you let the program set the project preset for you. You will most likely end up with the default NTSC AVCHD Full HD1080i30 which is inappropriate for your project. So, before thinking or acting on Get Media....open a new project, go to File Menu/New/Project and set the project preset in the New Project dialog for NTSC DV Standard or NTSC DV Widescreen depending on what you find beforehand about the properties of your VOB MediaInfo Then use Add Media/and the appropriate choice based on what I wrote above about VOB already ripped vs DVD-VIDEO ripping.
c. When you have your VOB on the TImeline with the appropriate project setting, right click the file in Project Assets and verify Premiere Elements 11's interpretation of the file frame rate and other to determine if it agrees with the MediaInfo readout. It would be very unusual if there was a differnce, but...
d. Whether you have a NTSC or PAL project, all the SD DVD Templates have a frame size of 720 x 576 (PAL sizing). The ones tagged HD have a 1440 x 1080 frame size. Right now I would advise you to stay with the SD ones, but not be afraid to experience with a HD choice if it appealing and see what happening during encoding.
e. In all this, you did not say what the duration is of this 481 MB VOB file. The standard DVD disc is spec'd at 4.7 GB/120 min. That 4.7 GB in reality is 4.3 GB. You will frequently see the recommendation "for best results, do not exceed 90 minutes on this standard type disc". When you have your DVD disc in the DVD burner tray and are in the burn dialog of Publish+Share/Disc/DVD make sure to check the Quality Area of the burn dialog for the Space Required and Bitrate reading (8.00 Mbps is the max reading).
Based on what you wrote, I suspect that most of your problems were related to incorrect project settings. By the way, if you want to get rid of a menu button text, most of the time double click the text to bring up the Change Text dialog, highlight the text there, hit the delete key of the computer, then hit the space bar or enter key.
If you are replacing the menu's audio, max 30 sec with looping. If you use motion buttons in the menu, max 4.9 seconds. After you get the details of the project setup OK, we can focus in more on the menus...number of Timeline markers etc, and customization of the menus from within the program.
Lots of details. The answers and successes will be in the details. All the contributors here have given you a lot of ideas for exploration and experimentation.
Please do not hesitate to ask if you need clarification on anything that I have written.
Looking forward to learning of your progress.
Thanks.

Bad pixel preview with bitmaps

Hi,
Is there a way to overcome the bad pixel preview me and my colleagues have in Illustrator CS5 when using bitmaps?
In CS4 we never had such a problem, now there is for bitmaps almost no difference between the overprint preview and the pixel preview.
In other words - noisy (like in the Photoshop noise filter)!
That is a real problem because we use bitmaps a lot for fabric prints and T-shirts.
Please advice

For the same reason as the guys on this topic are complaining....
http://forums.adobe.com/message/2786211#2786211
There is allmost no difference now between the overprint preview and the pixel preview when we talk about bitmaps...
Please dont answer the same things as in the linked topic. Let me know if there will be a fix or not. That's all I want to know.
In meanwhile I'll continue working on cs4 - because a that nice preview is crucial for our work!
Kind regards,

Bad pixel patch correction in 2D image

In one CCD image (600X800), I have few patches of bad pixels (few are in irregular shapes, few are in regular one like rectangle of 8X8 pixels). For correcting these bad pixel patches, I am looking for some surface fitting function, which should have provision for excluding the defined pixel location.
These bad pixel patches needs to be computed by fitted surface only.

ashok_kumar wrote:
HI Thoric,
Thanks for reply,
When I convert the image in 2D array, bad patches also comes into 2D array.
of course...
and when I tried interpolation2D.vi, it considers these bad pixels for interpolation also.
I need to exclude these pixels for fitting (interpolation). How to exclude these points ?
Kindly help.
exactly, and this is where it gets complicated. So long as you know where the good and bad pixels are you can work on subsets of the 2D array that contain only one bad pixel, replacing that bad pixel with an interpolation of the surrounding good pixels. So, try working on 3x3 or 4x4 subsets that each contain only 1 bad pixel and perform the interpolation on each one at a time, putting the new interpolated result back into the original 2D array. With a knowledge of where each bad pixel is you can attack each one singularly.

How can I increase resolution when burning a dvd with elements 11 premiere

How can I increase resolution when burning a dvd with elements 11 premiere
I am trying to generate a slide show DVD....the pictures on the TV are poor quality

Welcome to the forum.
As Steve points out, a DVD-Video is set in resolution, to 720 x 480 (for NTSC), in either Standard 4:3, or Widescreen 16:9. That is as good as it can get, and is not a limitation of PrE, but of the DVD-Video specs, which were written a long time ago.
The best that one can get is to play that DVD-Video on an up-rezzing DVD player, or most BD players, that also have up-rezzing, to an HD TV monitor. Those players have dedicated chips, JUST for up-rezzing.
Then, and per Peru Bob's questions, I attain the ultimate Still Images to DVD-Video, by doing my Scaling in Photoshop, and using either the Bicubic Sharper, or Bicubic Smoother Scaling algorithms. I Scale my Camera RAW Images to match my Project's Frame Size, and Crop, where necessary to match the Aspect Ratio of my Images, to the Aspect Ratio of the Project, i.e. if going to a 16:9 Widescreen, I will lose some pixels top and bottom, but I account for that, per my asesthetic.
Note: some PrE users insist that the Scaling in PrE is as good as Photoshop's, but my critical eyes point to using PS. Also, I do NOT use JPEG, which is a lossy, compressed format, and will Save_As PSD from Photoshop, for ultimate quality.
Good luck, and please let us know the pixel x pixel dimensions of your Images.

DV clips look bad, good when converted to H.264 in QuickTime and reimported

Still a problem after 7.0.1:
DV camera -> iMovie 08 -> looks bad when playing and exporting/sharing
DV camera -> iMovie 08 -> "reveal in finder" -> clip opened in QuickTime -> looks good -> export as H.264 -> re-import to iMovie 08 -> looks good when playing and exporting/sharing.
In plain words: Importing DV clips from my DV camera into iMovie gives bad results when playing and exporting/sharing. Have tried everything, but the clips look blurry and not sharp at all. The actual DV clip in the events folder looks sharp and clear.
If I take the very same DV clip from the events folder ("reveal in finder"), open it in QuickTime, export it as H.264 and then re-import to iMovie 08, it looks brilliant, retaining the quality the DV clip in the events folder has.
Why can't the DV clips look good in the first place? What is it that iMovie 08 does to these poor clips? Some have suggested re-encoding, re-rendering and so on, but if I do just that in QuickTime and re-import it to iMovie 08, it still looks razor sharp and crystal clear. No reason that iMovie 08 shouldn't handle the DV file in the same manner.
Some have suggested that this is because iMovie 08 internally re-encodes to AIM or H.264, enabling edits with different kinds of formats, but if I do this myself in QuickTime before importing to iMovie 08, the problem isn't there!
If this is difficult to achieve, why not add the option of importing from a DV camera as H.264 and not DV? That would make my day!
(I have posted this to Apple using the feedback menu item in iMovie 08.)
(Background here in these threads:)
http://discussions.apple.com/thread.jspa?threadID=1088568
Sample clips in Apple TV format here:
http://discussions.apple.com/thread.jspa?messageID=5173005

iMovie '08 stores rendered projects in H.264 form. This happens when you render to the Media Browser. The rendered file(s) (you can have several different sizes) are in the iMovie '08 project package. The original flies in your Events folders stay in whatever format they were in.
Yes, the movies exported to the Media Browser use the H.264 format, the same as iMovie HD 5/6 did when we exported using the presets Email, Web, Web Streaming and CD-ROM. They were all H.264 too. Apple is obviously putting the (powerful) H.264 to good use to prepare movies for Web pages and other purposes.
As you know, the Full Quality export in 5/6 was to the project's native format, which varied according to the type of project. For DV projects, that was DV video. Everything was converted to DV when imported into the project, and to preserve the original quality we could export to a Full Quality DV movie.
There is nothing like that in iMovie 7, at least that I've seen. As you said, nothing is converted to a "native format" when imported to the project. (Still images are added to the project's single Apple Photo - JPEG "Still Images" movie, which is a nice twist.)
So I think of iMovie 7 as having no "native" format, but a nicely-designed path for using H.264 as the delivery format. The Media Browser — a virtual library of movies with no shared place — is a nice invention.
When I export slideshow movies in DV format out of FotoMagico I always select 'Best' and it DOES make a difference in iDVD.
I think of iMovie 7's problem with DV as more profoundly flawed. Exporting ANY DV video that's in the project to DV or ANY OTHER format is messed up. It's the handling of the DV inside iMovie that's messed up, not just the export to DV.
My guess is — and it's only a guess — that FotoMagico's Best setting adjusts the content of the image delivered for iDVD. Put another way, it prepares an image that works best with iDVD's own encoding algorithms.
One long-standing diappointment I've had with iLife is that Apple has never coordinated the image it prepares for iDVD with what(ever) iDVD does best. It's as if the programmers never talk to each other. iMovie engineers have never asked the iDVD engineers how best to deliver the image to deliver the best quality on the DVD.
Given Apple's emphasis on H.264, one would think that iDVD would be written to embrace any H.264 video and deliver great quality on the DVD. It doesn't. And with iLife '08 it doesn't even embrace iMovie's own DV exports!
I suppose Blu-Ray will change all that, but for now we're stuck with a version of iLife that can't deliver a quality DVD of our home movies.

Bad resolution when I save for web

Just got Illustrator CC and its really bad resolution when I try to save for web on my new MacBook pro Retina (Don't know if it got anything to do with it)

if you draw something using paths in illustrator and save it as AI or PDF, it will maintain those paths and draw its appearance (strokes etc) to whatever resolution you screen is at (or whatever you print it at). if you save something for web, it will convert those appearances into pixels. if you zoom in on those pixels, all they can do is get larger and make your image appear more blocky. when you save for web, you want the resolution of what you're saving to be the same as the resolution it will be used at. if you save an image at 100x100 pixels and then view it at that size on screen, it will look as good as you screen is capable of showing. if you enlarge it, it won't.

How to add bad pixels to a DNG made from a CFA sensor raw data ?

Hello all, I'm trying to build a proper DNG file from the raw CFA image acquired directly form an industrial camera.
As usually there are a number of bad pixels around and I would like to mark them in the DNG so they can be correctly interpolated when the image is processed.
In the latest DNG SDK (1.4) I've only found this rather thin references:
"Defective Pixels
There are two ways to deal with defective pixels in DNG.
The first is to map out (interpolate over) the defective pixels before storing the raw data in DNG.
The second is to include a bad pixel fixing opcode in the OpcodeList1 tag."
OK, as each program/customer/etc. seem to have its own ( best ) algorithm to interpolate the bad pixels then OpcodeList1 it is.
But then I've got this: FixBadPixelsConstant and I'm not clear about its usage, especially BayerPhase, is the same BayerPhase that is specified as a global property of the CFA or it is something separate and what ?
Also is there some "industry standard" value for the Constant that will make more likely the established programs to process correctly the image ?
And this Constant value is unique per DNG or can it be more ot them added, i.e. to somehow characterize the "badness" of the pixel, like reduced sensitivity, stuck at 0/max, etc ?
In the end if somebody can share an one-liner on how to add programatically this tag using the SDK I'll be very grateful.
Sorry for my newebie questions and many thanks for your help.

Hello Dear
Look FB60 screen has two parts :
The one in which you enter information related to vendor is Header Level, in this case you already assign Personnel No. in Vendor Master so no field is required as Personnel no. will be picked up from Vendor Master level.
The Other is line item level is bottom half part, if you want to assign personnel no. at Expense G/L level then if you scroll right you will find a field for Personnel no. If you can't see the field check your setting at OBVV for the field status group you assign to particular Expense G/L.
Hope you Understood
Cheers
