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.
Yours Bengt W

  • 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.

  • 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.

    Hi,
    I'm using 10.0.7. It's like snapping won't turn off. Instead ,if i use the keyboard to nudge the clips, there's no problem. I am using that at the moment.

  • 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.

    Like everyone else here, I'm just an iMovie user who volunteers to help answer questions.
    Unfortunately, recent changes to the Discussion software introduced bugs that make it very difficult to reply to user questions. Despite assurances by Forum administrators, these bugs are not being fixed.
    This is to ask that you contact Apple, suggesting that additional resources be allocated to fixing the Discussion software. Hopefully your support will encourage Apple to address these problems.

    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.

  • Multi-camera timeline edits all messed up

    Sometimes when I reopen a project, the edits I made using Premiere CC's new multi-camera sync and editing tools are all out of whack. Toward the second half of my edits they will start switching out with shots that weren't even the same layer or camera... It has happened twice to me so far.
    I merge clips, sync, create the timeline from sequence, do some multi-camera editing, and then go back and make adjustments to the timeline because some clips are out of whack. Everything seems to work fine and then all of a sudden it's all messed up!
    Does this happen to anyone else?
    Side note: Don't try to adjust the "speed/duration" of an edit on a multi-camera timeline, it crashes

    By referring to merge clips I mean the new workflow where you select clips you want to sync in the project panel and right click > "Merge clips."
    I wrote that in kind of a rush and the terminology with the new type of sequence that represents a multi-camera sequence (but the icon is different from a timeline and you create a timeline with it that you edit it in using multi-camera editing mode) is a little fuzzy to me.
    I think there is bug somewhere though in editing on that timeline you create from the multi-camera sequence... possibly having to do with edits made that are beside the multi-camera ones, like if I use the razor tool and move something. I am going to try to look into it more.

  • Does iPhoto '06 have better editing tools?

    I've read that iPhoto '06 has better editing tools than '05. Could someone explain?
    Is the Retouch tool's brush still so large it can't be used on small blemishes?
    Does the red eye work any better?
    Is there any way to adjust the shadows and the highlights separately? Or, ideally, is there something like the shadow/highlights tool from Photoshop?
    thanks,
    John

    John,
    The Retouch brush appears to be the same size. However it is much more effective than it was in 5. Tiny wipe clear up blemishes. Clicking on a blemish used to effect it very mildly. Now clicking on a blemish twice clears it up.
    Red-eye is rock solid. It appears to be even better than it was in iPhoto 4.
    The Adjust dashboard did not change, so you don't have anymore contols than the B/W sliders, Exposure, Contrast and Brightness.
    Effects Dashboard was added. It's limited: BW, Sepia, Antique, Saturate, Desaturate, Matte, Vignette, and Edge Blur.
    The MakerNote bug that slowed launching and shutdown of iPhoto 5 appears to have been fixed in 6.
    So there's not a lot new, but it does what it's supposed to do much better.

  • 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.

  • Set default Settings for Brightness/Contrast Slider

    I am in the throes of editing several hundred pictures. My camera has a standard tendency toward too bright and not enough contrast. While editing about a hundred pictures in Photoshop Elements 3.0 last night, the brightness/Contrast and Shadow highlight slider suddenly retained the last setting - which GREATLY enhanced my editing efficiency! Alas, today it is back to normal - the Brightness/Contrast slider default is 0 for it's associated sliders and the Shadow Highlight option is again at 50%/0/0 for the three associated sliders.
    Is there a way to set a default value for the associated sliders for each of these?
    (I had installed Photoshop Elements 5.0 on a trial basis up until yesterday and also have Photoshop Elements 4.0 installed, but it is such a hassle to use, I just gave up on it (and 5.0 has the same issue as 4.0 - no concurrent file browser when editing.))

    Can't help you with Shadows/Highlights, but you do have an option with Brightness/Contrast. Instead of going to Enhance>Adjust Lighting>Brightness/Contrast, go to Layer>New Adjustment Layer>Brightness/Contrast instead. Once you've established the parameters you want for Brightness and Contrast, you can open up additional pictures and drag-and-drop the adjustment layer onto each new picture, retaining the settings from the first adjustment. This also allows you to quickly tweak the settings on the succeeding pictures, as adjustment layers can be readjusted ad infinitum.
    If only Shadows/Highlights had an adjustment layer option...

  • How do I configure the brightness, contrast and colour settings of the built-in HD Camera on iMac?

    I have recently purchased an iMac after making the switch from PC.
    I am struggling to find an app, or settings configuration where I can modify the brightness, contrast, color and white balance settings for the built-in HD camera. The online manuals didnt give me any answers so I thought I would turn to the communities pages for some help.
    The room where the iMac is situated has a light behind me and I am facing the wall so not much light in front of me except the ambient light from the screen. Friends on FaceTime, Skype etc. say that the picture from the built-in camera is too dark and difficult to make out my face clearly. How can I fix this?
    Any and all help is most welcome.
    Thanks
    UKRichard

    I would move it if it weren't the main room light that is fixed to the ceiling. Not remodelling my house just for the iMac camera. On my old PC all the webcams came with utilities to adjust these settings, I am surprised Apple dont have something similar for free.
    I did see another post about iGlasses here, but not sure I want to pay $10 just to adjust my camera settings

  • Cursor for text and other editing tools is too light to see

    I have a new Macbook Pro Retina display running Mavericks.
    When I use editing tools (like text, shapes, etc.) in apps like adobe acrobat, fireworks, and photoshop the cursor is so light grey that I can barely see it on the screen.
    Does anyone know how to change the color or contrast of the cursor? Is it even possible?
    This is impacting my productivity by at least 10%. Don't tell my employer or I might get fired.

  • Difference in video brightness/contrast across viewer applications

    I am using FCP->Color>FCP roundtrip to grade Red footage. After I grade the clips in Color and send them back to FCP, I see a difference in brightness/contrast of the graded clips when playing in FCP. And when I export the final output to quicktime and play it in quicktime player, I see further difference in brightness and contrast. Essentially the clips appear darker when played in QT player. Now I am confused as to which application is showing the correct brightness/gamma level? Is there a way to make all the applications play the video at same/true brightness/gamma? Any insights would be highly appreciate. Thanks!
    -Pranab

    There is a distinction between PCIe-based GPUs and I/O cards that you have to be aware of. COLOR's user interface, render/scopes and output are split between the two. A graphics processor handles the user interface (PCIe is better, application won't run on on-board integrated or AGP), and actual grade values for judgement are based on a PCIe HD-SDI I/O card like AJA Kona3, or Blackmagic (Intensity?) which are NOT graphics cards, they are video interfaces.
    For GPUs, if the application is running, that's a good indicator. However, preferred cards have been evolving over the past 5 years. My first system was configured with a Quadro 4500FX which was a total waste of money. I deliberately chose an ATI X1900XT for the next tower, which was a significant improvement. My third MacPro is running fine with the default ATI 2600HD, which is as plain vanilla as you can get. Some users report speed advantages with the newer 4870 series, but I fail to see significant differences -- COLOR in its current delivery will never deliver "real-time" preview playback on any card, and it still takes a very long time to render, in comparison with some other grade offerings. Fourth machine, I'm still deciding, but it would be great if Apple got the FX4000 thing happening, and I'll get to that.
    Nvidia does suffer from some bit-depth processing issues in that it does not directly support 10-bit codecs, but can be switched into the more intensive "float" mode. It also has some other transient issues.
    Looking outside Apple COLOR, consider that Blackmagic Resolve ("DaVinci") is predicated entirely on nVidia's CUDA-processing technology and is restricted to implementation on 2 or 3 very specific cards, as opposed to the FCP-centred, but ATI/AJA-leaning Apple solution, which, although somewhat restricted, is 90% more likely to run on almost anything PCIe that you can stick into a MacPro. However, the color science and cross-platform (AVID support, for example) that DaVinci offers makes it very tempting, and that's why I'm paying a lot more attention to nVidia these days.
    If you are looking for HDSDI PCIe cards, then AJA, with IO, Kona3, and so on definitely has the edge and can extend capabilities up to and beyond 2K processing, but many users select other solutions that suit their individual needs -- not everyone delivers theatrical Digital Cinema or needs to.

  • 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 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.
    Powermac G4   Mac OS X (10.3.9)   using FCP 4.5

    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.

  • Selection tool automatically becomes rolling edit tool when trimming

    I did something and I'm not sure what. But my selection tool has changed. Now when I try to alter the length of a clip in a timeline, it automatically switches to the rolling edit tool with the 2 arrows on either side of a line. If I try to just grab the end of a clip it also drags the end of the clip beside it as well. It affects inserts and almost anything I do. I can't figure out how to return my selection tool to normal.
    Please help.
