Metering issue between FCP and STP

Hello folks,
I'm having an issue when I export a piece of audio from FCP to STP. Once it is in STP, I normalize it up to 0 db. When this is complete, the meters peak in the 0 db range. When I save and return that same piece of audio back to FCP, it will now peak at -12 db. I'm unsure of why there is a discrepency in the meters. Why does it say 0 db in one program and -12 db in the other? I'm not sure what I'm missing and was curious to know if others have had this issue as well.
Mac 2.0 G5   Mac OS X (10.4.4)   FCP Studio
Mac 2.0 G5   Mac OS X (10.4.4)   FCP Studio

Yes the meters are all wonky in STP. My guess is that whoever designed them does not know the first thing about audio post production or digital metering and work flow between formats.
If Final Cut Pro uses -12dbfs as their reference instead of sony -20 standard then so be it, but broadcast standard is -20dbfs = 0dbm
It looks like they have taken the -12dbfs = 0dbm and included it into the meters in STP. So they are no longer using the -12 ref correctly and are not actually Digital Full Scale Meters but an entirly NEW kind of meter that Apple has design for the purpose of?
So a REAL -12db full scale signal shows as 0db full scale in these meters what ever they are. Not rational or useful. Plus the balistics are from outer space. You cannot seem to tell how close you are to the imginary O reference they are using.
I repeat: A REAL - 12DB Full Scale signal, shows as 0db Full Scale in these meters adding to an already confusing hodge podge of digital references.
Minor discrepency
So if you want to master your audio close to 0db full scale for DVD you will have to use a different program as 0dbfs does not exist on these meters! So when you hit +12db on these meters the signal is actually 0dbfs on ANY OTHER FULL SCALE DIGITAL METER IN THE WORLD.

  • Why can't I use WebCT chat with my computer?  I get the 'spiral of death' every time I try to type in my chat.  I have a feeling it has to do with compatibility issues between Java and Tiger.

  • Compatibility issues between R12 and report builder 2.5

    Hi,
    I just want to know if there are issues between R12 and (Forms 4.5 and Reports 2.5)? I have been using 6i since I started in the oracle so I'm a little new to this.
    Thanks
    peopsquik

    As my understanding there is no issue for Forms 4.5 and Reports 2.5 with R12.
    You can develop report with Report 6i can be deployed with R12.You cannot use Forms 4.5, Reports 2.5 or Developer (Forms/Reports) 6i with Oracle EBs R12 as it is not certified. The only supported version is Developer 10g

  • Missing "(sent)" files roundtripping b/n FCP and STP

    Sorry, but I'm posting this here because the STP forum is quite slow to reply. And, I'm not sure if this is an FCP or STP issue.
    I have just finished my first project using STP. I was doing a lot of round tripping b/n FCP5 and STP (about 15 clips) and everything was working splendidly. Airconditioner noise easily zapped! A beautiful thing. Annoying pops and cracks removed with just a few clicks of the mouse. More beautiful things. Then...I finished the project (thank gawd), output via Compressor and into DVDSP. The final DVDs are produced and the client loves them. But, I had both a 30i and 24Pa version of the project. I had originally edited the 30i version and then duplicated this project and removed all the Advanced Pulldown to produce the 24P version (without having to re-edit; another beautiful thing). Note, I DID NOT do the STP round-tripping until the 24P version of the project. After everything was complete, I deleted the 30i project (it was never needed) leaving just the 24P version on the internal disks.
    Suddenly, when I next opened the 24P version of the project ALL OF THE STP-FIXED AUDIO WAS GONE! NOW OFFLINE!!!
    Where the heck did they go? And, where were they originally? When you round-trip like this, what kind of file is STP (or FCP) creating? In the Browser, I noticed FCP creates a new audio file clip icon and appends "(sent)" to the original audio clip name (e.g. an audio clip with the name "21DConfRoom03" has a duplicate? audio clip created, presumably by STP, with the new filename "21DConfRoom03 (sent)")
    Where are these so-called "(sent)" audio clips source stored on disk? Where in the standard FCP file structure are they? Is it possible FCP was putting them into the 30i version of the project file structure by mistake? (remember, i first edited in the 30i project version before duplicating and creating a 24P version).
    Any help is appreciated.
    Thanks,
    -Michael

    When you say ProTools outputting individual aiff, is it a mix down file?
    Yes. I have certain audio configurations that we need to output for the networks. Ch1 & 2 are a stereo mix, then CH3&4 might be Mix minus Music, then Ch5 Mono Dialog, Ch6 Mono Prod Audio. Ch7&8 SFX....9 and 10 Stereo music.
    So the mixer mixes down what we need for the various tracks.
    Also, as I change my film, is there any way to update the found files in ProTools?
    Don't change your cut. You should not be sending the audio to the mix if you aren't done cutting. You wait until you have picture lock, then send the audio. If there is a change, then you re-export the OMF, they reconform, and send new tracks. HOW does the audio guy conform? Got me...I just know that they can.

  • Significant color shift between FCP and COLOR?

    Hi there,
    I get a significant color shift when sending footage - either adjusted or unadjusted/unmodified - from FCP to COLOR.
    Before anyone asks, the color shift is visible both internally or on an external broadcast preview monitor.
    From within COLOR, I 'send' back to FCP this sequence - which is still without any form of adjustment (apart from being sent to COLOR), the apparent color shift is now visible/added to the imported sequence (from Color).
    I've tried this on three separate Macs:
    1. The Mac above (6.0.6). (Leopard)
    2. A Mac with the same version of FCP as above. (Snow Leopard)
    3. FCP and on a third Mac with an earlier version of FCP. (Leopard)
    Does everyone have the same problem?
    If not, does anyone have a solution?
    Cheers,
    Dan
    PS: I've tried:
    FCP > Color ProRes contrast shift
    http://discussions.apple.com/thread.jspa?threadID=2150962&tstart=75

    I had the same problem except that I am using version 1 of color and Final Cut Pro 6. I isolated just the video and double checked that I had no filters or if I did I turned them off. I had a smooth cam filter on one shot, but that didn't effect it. I was then able to send it to color without issue, once I had no sound or filters or transitions messing up the pass between final cut and color. Try doing the same, just duplicate or copy your timeline to a new timeline. I would have rendered your footage out to ProRes however as using the DVC Pro codec is probably not ideal. Color also only works with actual full raster files, not so good going from HDV or DVC Pro as they have an anamorphic frame size. This may be causing issues also.

  • Color differences between FCP and Motion

    Forgive me if I'm breaking any unwritten rules here as I posted this same topic on the Final Cut forum the other day..so bear with me as I hope to find some insight here from the many experienced (and extremely helpful) Motion users on the motion forum.
    OK...here's my dilemma. I create a graphic/text page in Motion working with the RGB colors from a style guide provided by an agency. I then drop the motion project into the FCP timeline and the colors between the 2 applications are different.
    I'm attaching a link to 2 jpegs that show the different RGB readings with the DigitalColorMeter application.
    http://www.myphotos.yahoo.com/s/218qifk6fseemvbmprlw
    In my Motion project the meter tells me that the dark blue color is RGB-11,44,99
    In my FCP timeline the meter tells me that the dark blue color is RGB-4,30,79
    I gather from some forum research that this may have something to do with gamma levels...my FCP setting has the Imported/StillRGB Video Gamma setting set at Source.
    I'm hoping that someone can explain to me why the DigitalColorMeter readings would be different between Motion and FCP...and what I might do to feel confident that my Motion files would import correctly into my FCP timeline.
    Thanks in advance to any insight....
    Jay

    After some more exploration...turning things on and off, changing sequence/gamma setting, and the like...I now realize what the issue is.
    When the background setting in my canvas/edit window is set to black the colors are accurate between motion and FCP.
    Once I change the background setting in the canvas/edit window to white or checkerboard there is definitely a shift in color/gamma. Not sure why that is...maybe someone can explain

  • Updating Final Cut Studio 2.01 and workflow between FCP and AE

    Hi. I am currently working in FCE 3.5 and am considering purchasing Final Cut Studio 2.01 (new and sealed) as opposed to the latest version since I am running a PowerPC G5. Am I assured of being able to download all the updates for Final Cut Pro 6 and exactly which version would be the latest and final one? Was there ever an FCP v6.5? I do mainly animation/motion graphics and work in After Effects (along w/ Flash, Carrara, Photoshop, Illustrator, etc.). I understand that the workflow between FCP (as opposed to FCE) and AE is greatly enhanced. Can someone give me an idea of what advantages this new workflow will offer in terms of what I'll be able to accomplish that I can't do now w/ FCE? Also, any other comments on how FCP (as compared to FCE) will benefit me as an animator will be greatly appreciated. Lastly, am I correct in assuming that I will be able to open my FCE 3.5 project files in FCP 6 but not visa versa? Thanks. Jack.

    Thanks for the replies everyone. I see that I will need some 3rd-party support in order to realize the benefit of a Final Cut Pro/After Effects workflow. Have another question. What are the kinds of filters that you can keyframe in FCP but not in FCE? And are there many filters in FCP that are not included w/ FCE? As I deal mainly w/ animation as opposed to footage of live video I am trying to justify the investment in Final Cut Studio 2 in terms of it being a benefit to me as an animator. I currently use FCE 3.5 (which includes versions of SoundTrack and LiveType) and After Effects CS3 plus other graphics programs. I would love to be able to work within DVD Studio Pro as iDVD is so limiting as an authoring program but am not sure how much I will benefit from switching from FCE to FCP. This is what I am trying to nail down.

  • Sync issues between Mac and Mobile Me

    Hi all,
    I'm having issues syncing between MobileMe and my Macbook Pro. It used to work perfectly, but I haven't been able to get it to sync since early August. All the changes I make between my iPhone and MobileMe work fine, but they just wont update with any changes I make on my Macbook. Equally, changes made on iPhone or MobileMe don't show on my laptop anymore.
    I've tried force syncs and resetting sync data (and transferring info from MobileMe) but none work. Is there anything else I can try?
    Thanks,

    You should ask in the MobileMe forums as this forum (iSync) has nothing to do with syncing Macs to MobileMe.

  • Curious... Syncing Issues Between iPhone and iTunes?

    Just curious... the past several months I have noted various concerns around "syncing" between iPhone and iTunes... yet don't recall any mention of whether it occurs between MAC OS or WIN hardware (desktops and or laptops). Furthermore, I am interested if anyone can comment whether these sync issues occurs mostly on TIGER or LEOPARD OS when accessing iTUNES. (Guess I should pay more attention to the noted OS field.
    I ask because I am considering an upgrade to LEOPARD by end of month and don't want to jeopardize my syncing to my iPhone if it is a LEOPARD related issue. Thank you

    I'm running Leopard and I've never experienced any sync issues.
    These discussions include mostly problems, which is what these discussions are for - a user to user support forum for technical support issues and questions.
    Which particular issue are you referring to?
    Before installing a major OS X upgrade such as Leopard over a previous OS X version, it is a good idea to create or update your existing backup of important data stored on your computer's hard drive - including your iTunes library, photos, contact info, calendar events, documents, etc. I've never experienced any problems installing a major OS X upgrade over a previous OS X version, but I always update my computer's backup immediately beforehand to be on the safe side.

  • White space issues between content and footer.

    I am having white space/page length issue between the end of my content and the footer.
    I have read the forums and tried changing the page length minium height to 800 and then I
    unchecked the sticky footer in page properties on both the master page and the content page itself.
    Here's a link to one of my pages.  http://www.ueonline.com/rohs-info.html
    This page has very little content and you can see the white space.
    Any help is appreciated.

    This may be a little dated for a reply, and I'm not 100% sure your issue is the same as mine, but I discovered that unchecking the sticky footer option in site properties solved the problem. I should note that the website I was building for a client was über simple, and while disabling that function solved the headache in my own project, it may incur unwanted results in others, depending on the complexity.

    > over a centered frame
    You are not using frames - that's a table.
    Yes - there's a way to do this, but it will involve your
    working in code.
    Make your page left aligned by removing any centering.
    Then position your layer so that it is properly located over
    the table.
    Change this -
    </head>
    to this -
    <style type="text/css">
    #wrapper { width:760px; margin:0 auto;position:relative; }
    /* 760px will display on an 800px screen maximized browser
    window without */
    /* horizontal scrollbars. */
    </style>
    </head>
    (you may need to adjust this width so that it's consistent
    with the width of
    your centering table)
    change this -
    <body ...>
    (the ellipsis represents any other attributes that might be
    mentioned in the
    body tag, and SHOULD NOT BE INCLUDED EXPLICITLY!)
    to this -
    <body ...>
    <div id="wrapper">
    and this -
    </body>
    to this -
    <!-- /wrapper -->
    </div>
    </body>
    and see if that helps.

  • A big issue between LR2 and PSE6?

    Hello;
    Im experiencing a strange situation between PSE6 and LR2. What about to tell you it happens to me twice, so I was able to recreate and document the issue. Before I go on I want to warn you that the only way to fix it was uninstalling and installing PSE6. The repair process did not work.
    Before I describe and specify the Test Script I want to describe my system:
    Vista Home Premium SP1, PSE6 and the 30 day trial of LR2.
    Processor: Dual 2.89 MHz, 4GB of RAM, 512MB ATI Graphic Card
    2 Internal HD; 250 GB and 650 GB
    1 External HD 500GB.
    Description: After I edited a RAW picture in PSE and saved as PSD I closed PSE6 and went to LR2 to continue editing, then after some editing in LR2 I decide to do more editing in PSE6 from LR2. I closed PSE6 and get back to LR2. I opened PSE6 from the Desktop and went to the Organizer-Edit-Preferences and BOOM; I get the message Adobe Photoshop Elements 6.0 (Organizer) has stopped working CLOSE THE PROGRAM.
    Test Script:
    WARNING: If you decide to go on and test this I want to warn you that both times I had to uninstall and install PSE6.
    1. Edit a RAW picture in PSE6 and saved as PSD, exit PSE6.
    2. Edit the same PSD picture in LR2, do anything you want.
    3. Edit the PSD picture in PSE6 directly from LR2: Develop->Photo->Edit in PSE6.
    4. Chose the Default Option: Edit a Copy with Lightroom Adjustments
    5. When in PSE6 do anything or nothing to the picture and CLOSE exit from PSE6.
    6. Start PSE6 and from the Organizer go to EDIT->Preferences and chose General
    7. Now, if the problem its repeatable and its not only me you should get the message that the Organizer has Stopped working and you must have to close the program.
    Organizer has Stopped working and you must have to close the program.
    8. Since everytime that I tried to get into the Preferences PSE6 Crash I had to unistalled and installed again, I try to do the repair but in my case did not work.
    Note: I don't know if the same it's going to happen with JPG's or TIFF's, at least I don't want to test it.
    If somebody has any comments or knowledge about this please let me know. For now my Trial of LR2 has come to a stop.
    Thanks in advance.

    Hello Antonio;
    After many, many test I discovered that the problem, at least in my case it is caused by the new ACR 4.5. Please read the Thread that I post under Camera Raw. I include the link below.
    I also open two Bug Reports about this, but as usual Adobe (and other Software Companies) will never take responsability for this, until one day they release a new version with "enhancements".

  • TE tunnel issues between IOS and IOS-XR

    Hi Guys
    I have a situation. The scenario (see the attached diagram) has to PE01 (IOS) connecting via a port-channel to P01 (IOS-XR), turn P01 connect to PE02 (IOS-XR). So we've configured a pseudowire between PE01 and PE02, this works fine! then we've configured a TE tunnel between PE01 and PE02, but when we chose the TE tunnel as preferred path for the PW, happens the following:
    PC-A mac address appears on PE02 mac address table, however PC-B mac address doesn't appears on PE01 mac address table, so there is not connectivity between PC's at all.
    It seems like the TE tunnel is causing some issue (thought TE tunnel status is okay at all), and the problem seems to be between PE01 and P01, when we take the TE tunnel from the PW preferred path, everything works fine! I'm not sure if this problem is caused by the port-channel too.
    I've been looking for some software bugs in IOS 12.2(33)SRE6 and IOS-XR 4.3.1 but there is not such.
    Anyone of you had this problem as well?

  • Is there an issue between EXSP24mkII and MOTU Symphonic Instrument?

    I'm using Logic Express 7.2 for three large projects right now. Admittedly I'm pretty new to LE 7.2, since just recently switching over from Digital Performer.
    So, far, LE has been very stable -- UNTIL last week when I loaded in MOTU's Symphonic Instrument. Now, if I have just one or two tracks of Symphonic instrument and nothing else, I'm fine, but if I start adding tracks that have different virtual instruments on them -- say, 2 tracks of Symphonic Instrument and 2 tracks of EXSP24 mkII, then I get frequent crashes.
    The crashes occur as I record my first take on the first new track.
    I can't seem to nail down a particular sequence of events yet, although I think I might be getting pretty close to figuring it out.
    However, before I put in all the effort to figure out the bug, do you know if it's already been discovered? Are there known issues between Symphonic Instrument and Logic or MacIntels, or something?
    Thanks!

    I do have the latest version -- the one that's compatible with the MacIntels. And, when it's the only plug-in, it works great.
    Well, maybe not quite as great as EXSP24mkII, but pretty good. There are still some wierd clicks that happen during playback occasionally, but, VERY fortunately, don't happen when I bounce the tracks down.
    It doesn't seem like there's a known issue, so I'll see if I can isolate a series of actions that cause the problem. If I can nail it down, I'll let you all know.
