Flickering in clips when brightness/contrast adjustments applied

In CS3 I apply brightness and contrast changes to a clip. When I view that clip in the preview monitor, and also when I view that clip after exporting to DVD on a television, there are intermittent random quick changes in the brightness. Screen appears to flicker irregularly. Any ideas as to why this is happening? It does not seem to happen on every clip I make changes on, but it is enough of a problem to be distracting. Thank you.

Dave, your responses are showing up blank. Are you useing email to respond? If so there must be a biug.
Im going to guess at you r problem based on the symptoms. Im guessing you used the Auto Bightness/contrast filter. The auto filter will do this because by dwfault it adjust every frame. Ergo you will see starl adjustments being made frame by frame. The fix is to increase the temporal smoothing parameter; that will cause the auto filter to look fwd and back in time and consider x frames before adjusting. But this will increase render times.
The other solution is to use the manual ver of the filter and not let it auto adjust.

How do I save an edited movie with brightness, contrast adjustments

I am using Quicktime pro ver 7.6.4(518.35) and I love its editing features especially the rotation and brightness adjustment features. Is it possible to save a move with these edits so they will be view correct with the basic Quicktime player? I have a movie that I edited the contrast and brightness and resave it as its original MOV file. The new contrast and brightness setting show up when I play the video on the same computer that has my Quicktime pro on it. But, when I play it on another computer with the basic Quicktime player the movie reverts to the original Contrast and brightness. Am I doing something wrong? I even tried to export it to another format and lose the video portion of the movie.
I would hope that I could fully edit a movie save it and give it to my family so they can view it like it was edited. Any suggestions?
Thanks.

Ok, after some searching, I found the export filter settings...
However, the exported video appearance does not match that of the source video with similar A/V settings.
Example 1 = Source video (.3g2) with A/V settings, recorded with screen capture software. *http://www.youtube.com/watch?v=ezvE6sUeUb0*
Example 2 = Source video with similar export filter settings (brightness/contrast) *http://www.youtube.com/watch?v=7tQYXWX17zQ*
When the video gets brighter, the brightness dims and when the video gets darker, the brightness increases... contrast settings seemed to be ignored.
All I can say is.. what the HECK?
It's pretty sad when I have to rely on screen capture software to get the desired result! Luckily the source video was taken with a cell phone, so there was no noticeable loss in video quality.

Saving AVI Brightness / Contrast Adjustments

Help !!!. I run lot of video clips of ultrasound images. I sometimes need to adjust contrast and brightness on the video clips to maximize image clarity. After adjusting the brightness and contrast with the AVI window option, I have tried to save the adjusted images. My problem is that the saved video does not reflect my adjustments. It is simply a duplicate of the video file before the adjustments. Can you offer advice ??

Phillips, the color settings under QuickTime 6 can be saved with the original movie. Are you saying that you can't save the settings under QuickTime 7 or are you just unable to export the changes?
In any case, QuickTimeKirk is correct, you can use the QuickTime filters to apply contrast and brightness changes. Also, have you considered using iMovie to make the changes?

Brightness Contrast filter won't stop flickering

My Brightness & Contrast filter is acting crazy. Most of the time, it works fine, but sometimes changes suddenly. Right in the middle of the clip, it will change brightness. Sometimes, it happens in brief flashes, sometimes constant, and other times, it rapidly flickers. This is only happening to certain clips, at complete random. Why is it doing this?
If anybody knows how I can stop this, please help.

Tried trashing renders. still can't figure it out.
It seems to happen on both the external monitor and the clip itself. Tried exporting into new quicktime movies, also as still image sequences and the flicker still happens to these certain clips when the contrast filter is applied. Seems to be embedded in the footage itself, but doesn't happen when there's no filter.

When i place my photo, the adjustments tab does not pop up, and even when i click image at the top, I cannot select any adjustments-brightness/contrast,hue-saturation, color blance, etc..Anyone know what I am doing wrong?

Applying brightness/contrast effect doesn't work

I have a project in the correct format on a properly formatted external drive. When I apply the brightness/contrast effect the red progress bar appears and the hard drive works for several minutes while the bar fills. But when it's over, the effect is not applied and the clip looks the same.
I have closed and restarted iMovie and tried again and I have trashed the Font Collections folder.
Any further help would be appreciated.

Have you tried disabling any third-party QuickTime add-ons or iMovie plug-ins installed on your computer? If something is messing up QuickTime that could cause iMovie to fail to render properly.

Brightness/Contrast edit tool messes up my clips.HELP!

When I try to apply brightness/contrast to my iMovie 6.0.3 video clips (because so many of them end up much darker on iMovie than on my camcorder), it helps with the brightness, but after the rendering is done, my clip is messed up in 2 ways: 1) the sound is mainly gone, except for a few jerky sounds here and there; 2) visually, the clip is now jerky--like it's both in slow motion and being fast forwarded at the same time, if that makes sense. I've tried again and again, looked for advice all over the internet, to no avail, and wonder if it's just a glitch in my software and if so, what to do about it? (I did download an update on 6.0 from the Apple site, but it didn't help). Thanks!!

Hi Z
As Catspaw writes.
The Brightness & Contrast tool in iM6 should work - a new account is a smart way to test
where the problem originate.
This tool in iMovie HD 6 - is crude and hard to use/get a good result with.
In iMovie'08 - this is one of the few things that is a real improvment but the loss
of so much other tools results in a useless situation (as Catspaw - I don't nearly use it)
Solution: FinalCut Express 4
• Superb tools to correct brigtness, contrast and colors
• So much more
Cons
• COST - It's not free but price is reduced with 30% after introduction of iMovie'08
• Some new learning. Mainly in starting up (setting up scratch discs & Capturing process)
Some says steap learning curve - there is a step but mainly there are so much new
tools so it's really to learn as You progress with Your movie.

Colored frames when adjusting brightness/contrast

Hello kind people. I am trying to adjust brightness/contrast on a short clip in my video, and I keep getting some colored frames that play when I replay the clip. I can stop at the colored clips, some are blue, and some are magenta. Anyone have an answer? I have rendered the clips, but I can't figure it out, and have never had this problem.
Thanks,
Mike.
Final Cut Pro 6.0.6

I reset the codec to Pro. All the footage I shot myself with the same camera setting. Also, I am only editing this one short clip, so it's not mixing with anything else I don't think.
I figured out a go around from my problem. Instead of going to Effects, Video Filters, Quicktime, Brightness/Contrast, I am now doing Effects, Video Filters, Image Control, Brightness. It seems to automatically take care of the contrast to make it look nice.

I am trying to use the brightness adjustment on a grayscale photoshop CS6 file. The preview shows the adjustment working and changes the brightness, but when you click to apply the change, it does not apply the adjustment. I have run into this problem before, although rarely, with some other files over the years and with earlier versions of CS. I would like to know how to overcome this problem?

Make sure you are viewing your image at 100%. At smaller views, pixels and layers and the way they interact are approximate interpolations and won't show you the actual pixel-for-pixel changes.

Image / Adjustments: Brightness/Contrast. Why is it crap now?

Ever since we got CS3, I have to hit the "Legacy" button in the Brightness/Contrast to get decent results. I just tried again WITHOUT using the Legacy button to enhance a scan a little. I brightened it up a few notches and then dragged the contrast bar and NOTHING happened. Whats that about? I hit the Legacy button and do my adjustments and it works as it should. Am I missing something?

Irregardless of the Premiere Elements version...
I do not believe you are doing anything wrong. I have not found it possible to copy a Timeline clip to which Time Remapping has been applied and use Paste Effects and Adjustments to other selected clips on the Timeline to achieve the same fast or slow motion for more than one clip at a time. For one thing the duration of the Time Remapped clip is different than those that have not gone through Time Remapping.
And, you cannot select more than 1 clip at a time to be taken into the Time Remapping workspace.
Also, special considerations need to exist for Pan and Zoom Tool for its pan and zoom effect applied to more than one photo at a time.

I will think about this some more. But, at this moment, it appear to be it is what it is.

How can I apply Brightness, Contrast, Saturation, etc on an color Image or Picture?

I am using IMAQ to open an existing color jpeg file, and perform operations on it. I would like to be able to change the brightness, contrast, saturation, etc. similarly to what can be done to an IMAQ Session via a property node. I've seen examples for grayscale, but not for color? Anyone have ideas / examples?
Thanks,
Tim

I found it -- IMAQ ColorBCGLookup.vi if others are interested.

Brightness/Contrast issue

when I add the brightness/contrast filter to my footage and adjust it-the picture looks normal,until I render, in which case I get flickering multi-colored frames. I'm editing prores422HQ footage at 23.98fps. The timeline is set to the correct setting, and I've tried different render settings with no luck. Any help would be appreciated...

In support of Jim, (and I don't know what camera you are using when I say this). But pro gear, tends to record in a bigger colour space (higher colour resolution 4.2.2) therefore when adjusting (using FCP filters for example) there's greater latitude to tolerate the adjustments. In my early days of single chip, just a few minor tweaks in brightness contrast can have the image fall off really dramatically, so you do need to get the image right when you record it i.e. even a single chip will record a great image when lit well, but under-lit, it's very difficult to make adjustments using FCP filters.

Brightness/Contrast in CS6 - Best Method?

Hi there,
Can anyone please tell me what is the best method for adjusting brightness and contrast in CS6? Is it by simply adjusting the Brightness/Contrast properties in an Adjustment Layer or is there a better way of going about it?
Thanks!

The advice I have gotten is use it on an adjustment layer. It's "non-destructive", won't permanently alter your picture and you can return to the picture for further adjustments or delete the layer later on.
When using the brightness/contrast setting, try the Auto button first, and if you are not satisfied with that, set brightness to 100, contrast to 50 and adjust from there.
Leave the "Legacy" box unchecked. It mimics how the older versions of b/c use to behave, causing clipping.
Yes, there are better ways, like curves,but I'm assuming you want to work with b/c for now.
