Poor Video Contrast and Brightness

Video display is dark and often difficult to see. I tried the five Rs approach, but still have the same problem. Any ideas
No problem with audio. Software is up to date.
30 GB video ipod unit.

I have a video that is too dark. My video controls have no effect on on the Sony camera mpg file. The movie plays but is too dark. Is there a way to get at least the brightness control to work?

You can use the ColorControlAdapter class. You'll find it at package com.sun.media.controls

How do I stop camera raw adjusting contrast and brightness automatically when I open any image

Every time I open in image in camera raw or Photoshop it is applying an automatic contrast and brightness setting. I have tried resetting to defaults with cntrl shft del but it doesn't make a difference. It also when I just flick through thumbnails on bridge. The pics look almost like they have a cartoon like filter on them!!any ideas on how I get it all back to normal it's been great in the past . I use cs3

Short answer, learn how to use the tool...
As for the "auto" adjustments, are you sure that's what's happening or are the images changing based on the differences between what the camera preview and the Camera Raw preview look like? If you have indeed somehow turned on the "Auto" adjustment and saved that out as a Camera Raw default, you can go into the Camera Raw flyout menu and choose the option to Reset Camera Raw Defaults. If however you are talking about the inherent differences between the way your camera renders raw and the way Camera Raw renders it, that's an entirely different discussion...
As for your other question, try rephrasing it as it doesn't mean a thing to me so I have no idea how to answer...

How to set RAW defaults for Contrast and Brightness?

When I open a RAW fole in PS Elements 8 the Brightness set to 50 and the contrast set to 25.
How to set these two values to 0 (zero) as a defaults when a RAW file opened for the first time (defaults).
Thank you for the help.
Leo

I think you can set presets in camera RAW (I'm at work now so I can't tell you the exact method), but setting contrast and brightness to zero gives you an ugly image, and you will most likely move the contrast up and the brightness up, so I'm not sure you are really gaining anything by having a default of 0 contrast and 0 brightness.
The defaults chosen by Adobe are reasonable.

Setting Contrast and Brightness while capturing.

Hi,
I have see in JMStudio that setting the contrast and the brightness during video capture is possible. For those who don't know how to do:
     -> Open JMStudio...
     -> Capture a video source
     -> Click on the pause button
     -> Menu Player/? (the last available)
     -> A window appears with 2 buttons, this is the right one.
So. I wonder if someone as done the same work without using JMStudio components and with SWING components ...
I am only looking for a JPanel with all controls and action implemented.
If YOU are this guy. Can you copy/paste your java file in the forum.
Tanks in advance.

hmmmm..further to my last posting if you are still around...how?

How do I stop camera raw automatically applying contrast and brightness when I load an image?

Everytime I load an image in photoshop or camera raw from bridge it automatically applies 50% brightness and 25% contrast and 5% black fill. It's ruining the pictures. I have already tried resetting photoshop and bridge to their default settings using cntrl, shift, delete. Any ideas?
thanks

I think you have posted your question in the wrong forum. This is the Acorbat Windows forum and not one of the image processing forums. Acrobat does not use the ACR plugin.

Contrast and brightness info

Hi,
I want to find out the Contrast Ratio and Brightness specs for as much macs as i can.
For displays you can easily find the specs but not for any other mac.
Is there a website or something where i can find this information ?
Thanks.

Specifications can be found at support.apple.com/specs/. But Apple does not generally provide contrast ratio information for Macs with built-in monitors.

Matched presets-but poor video quality and audio-PE9

I have posted a few threads like this before, but the problem has not been resolved. I have matched my 1920x1080 24p (Panasonic HDC-TM900) footage to the correct presets when I start a new project. When I play the clips in the timeline the quality is variable and often poor, but when I pause the video the still frame normally has high quality. Audio also sometimes cuts out. I have the MPEG2 codec installed so I really do not know what the problem is. Any help would be appreciated

Which project settings did you select, L3?
And which format did you shoot your video in? That cam shoots in several modes.
If you selected the correct project settings, there should not be a red line above your clips on your timeline? Is this the case in your situation?
If you are seeing a red line, then your video needs to be rendered. (Press Enter. When the rendering is done, the red line will be green and your video will play much more smoothly.)
However, if your project settings match your video specs, there will not be a red line above the clips until you add effects or transitions to them.
If you are shooting in 24p, that could be your problem. As you've seen, there is no project setting for 1920x1080 24p. Or for 50p or 60p, for that matter.
You must shoot your video in 50i (PAL) or 60i (NTSC) in order to successfully edit this video in Premiere Elements 9.

MacMini - LG 32" (32LB75) Problem - Poor video quality and now no picture.

Hi there, apologies for the length of this post....
I purchased a mac mini 1.8Ghz with 2Gb RAM yesterday with a wireless keyboard and mouse and hooked it up to my 32" LG 32LB75 using VGA. On startup the display looked ok, I managed to click through the various Leopard initialisations. I bought the machine for use as a front room media player for mainly DivX movies and the occasional bit of music.
Once I had installed the DivX codec I opened a DivX file in Quicktime and selected "full screen mode." As soon as the movie started I became quite disappointed. The picture quality was quite pixelated ("noisy") and certainly not as good as when I play the same movie file from my old dell PC on the same LG tv (the dell PC has a 64Mb PCI radeon 7000 which connects to the tv using the same VGA port as the mac).
Anyway just to give the mac a fair go I thought I would try out some genuine quicktime video samples from the itunes store (this time viewed from front row)....again not brilliant.
So I thought I would investigate the screen resolution to see if I could improve things. It appeared the resolution was set to 1900 by 1200ish I say "ish" because I can't remember exactly. I then attempted to reduce the resolution and eventually I settled on one that looked quite clear with the font size big enough to be easily read. Again I tried the movie and there wasn't much (if any improvement). Whilst changing resolutions the screen would go blank for a few seconds but on one particular setting (can't remember exact numbers) the display went blank and never came back. The tv now just displays "no signal".
I despaired and connected the mac to a 17" Iiyama montior that I use with a PC and it worked ok. However each time I tried to "hot swap" back to the television I would end up with no picture.
I'm really disappointed because everything else about the mac I really like. Particularly the remote for frontrow which is precisely what I wanted it for. The problem is I've spent over £500 and now seem to have a lesser quality picture than I had to begin with (ignoring for the moment that I don't have any picture!!)
Anyway my questions are these, answers to any or all most appreciated.
1) what is the easiest way to get my mini to start displaying on my tv again?
2) what would the optimum resolution be? My television mentions 1366 x 768 in the manual
3) If the mini doesn't offer this resolution in the pick list is it advisable to "force it" using some alternative software (ie 3dexpress.de)?
4) Is the video quality affected by the software player? ie would VLC give better picture with DivX over quicktime/itunes/front row?
5) How likely is it that the video resolution of my new mac mini isn't "as good" as my old dell machine with its PCI graphics card?
6) Finally if I don't get results as good as my existing PC setup, how accomodating are apple with refunds? I bought it from a UK high-street apple store. The back of the receipt mentions a "14 day not satisfied" return policy but then goes on to say something about being "unopened"...which seems a little confusing. Ie how do you know if you're satisfied until you've actually used it?

Hi there
the solution was to remove the various display config files in leopard and then restart the machine, this got my display back on the tv (albeit off centre). To fix the "off centre issue" I used the LG "auto correct" feature from the remote control "menu > screen" options.
The apple support site describes how to remove the affected leopard display files here http://support.apple.com/kb/TS2213?viewlocale=en_US As you will see their resolution consists of 2 main steps, the first one involves starting your machine in safe mode, if this doesn't work then you proceed to the second step where you remove the files using a terminal prompt.
I didn't bother with the first step mainly because I don't think I can start my mac in safe mode since my only keyboard is wireless (bluetooth). So I connected the mac mini to a 17" LCD monitor (which thankfully did display the video signal ok) and removed all the listed files using terminal. I then shut the mac down, swapped the VGA cable back to the LCD tv restarted the mac and it detected the tv and set a resolution that worked. I then very carefully reduced the resolution down to one that was recommended by my tv (1300ish.. x 768ish??).
At this point I was back to having an acceptable signal but still a little off centre. So I used the TV remote, pressed menu, went into screen options and chose "auto correct". Picture then filled the screen perfectly.
The problem seems to be, leopard lists a bunch of resolutions that it believes your tv/display can handle but it would appear that in fact some of these resolutions are not supported by your TV and if you choose one of these your signal disappears and you can't get it back.
I would still say that I'm not 100% convinced with the mac mini's onboard graphics (I have a 1.8GHz version). I'm going to download some HD content and see if that improves things, but certainly my existing DivX collection looked a little sharper and clearer and better coloured using my old dell PC with its radeon PCI card. But the difference in picture quality is outweighed by the convenience of its size and the font row interface. I might tinker with putting Windows Media Center on it one day, perhaps that might improve things.

Contrast, Saturation and Brightness settings for L...

I wanted to know how to change the contrast, saturation and brightness of the images from the built in camera app on Lumia 620. The app doesn't have the option to,change these settings... I was previously using a WP7 which,had these features, but they don't exist in the Lumia 620. So,is there a work around for these? Or is there a way to access these features, as the images come out very dull.

How to Change Brightness, Contrast and Saturation of an image in LabWindows/CVI (Urgent) ?

Hi All
I want to change brightness, contrast and saturation of an image, plz help me how it will possibe in labwindows/cvi
Thanks

CVI does not include native functions to operate such changements on an image.
It may be possible that these functions are included in IMAQ library, but I never used ot so I'm not sure. In any case, this is an additional tool to install and it is not free.
Alternatively, you may need to search for a third party library that offers such functions.
Proud to use LW/CVI from 3.1 on.

You can change the brightness with an RGBImageFilter which converts the rgb values to HSV, increases the value, and converts back to rgb.
