Why does Quad surround output 2 extra channels?

I'm running Logic Pro X, and when I try to bounce my project as an interleaved quadraphonic surround file, instead of 4 channels, the final file has 6. I know that this is due to the fact that Logic considers the "Center" and "LFE" tracks to be separate from the other surround tracks, but for my purposes I absolutely need the file to be only 4 channels. Is there some way to stop quad from outputting the extra two channels?

The way that the scaling works for DAQmx tasks changed somewhere between DAQmx 7.? and DAQmx 8.8.
At least it did for analog inputs anyway.
Check if any scale is applied to your analog output task. Try changing it.

    the channel is chosen by the WiFi router. If you don't want changes for whatever reason, set it in the router as manual and set the channel you want.

  • Why Does Premiere CS6 Output 29.97fps when Encoding to 23.976 fps?

    My project is XDCam EX, 23.976 fps. I exported to DVD MPEG and both VLC and Windows Explorer details report 29.97fps file format.
    I downloaded the latest updates two days ago. Just wondering why the encoder refuses to leave 23.976fps footage and project alone and convert it to 29.97? Render settings are clearly 23.976fps. Bug?

    i didn't read the forum i linked, so yes, i was wrong in the way adobe converts it to 29.97, pulldown vs added frame.  the output file will be reported as 29.97, but mediainfo can see the flags and reports it as 23.976 with 2:3 pulldown.  when i look at the .m2v file from premiere, frame by frame i can see the two interlaced frames from pulldown. so are those true interlaced frames or does the media player program generate those interlaced frames as a result of the flag telling it to?
    Telecine - Wikipedia, the free encyclopedia
    Wiki:
    Reverse telecine (a.k.a. inverse telecine (IVTC), reverse pulldown)
    Some DVD players, line doublers, and personal video recorders are designed to detect and remove 2:3 pulldown from telecined video sources, thereby reconstructing the original 24 frame/s film frames. This technique is known as “reverse” or “inverse” telecine. Benefits of reverse telecine include high-quality non-interlaced display on compatible display devices and the elimination of redundant data for compression purposes.
    my understanding is the interlaced frames are real. it is 29.97fps, with 2 of 5 as interlaced. the reverse pulldown reconstructs a single frame from the two interlaced, dropping the fps to the original 24p. is this not the case with adobe's pulldown?

  • Why does my speaker output balance keep changing?

    Hi,
    I've noticed that every now and again, the output balance for the speakers on my MacBook Pro (13-inch, retina display, early 2013) keeps changing randomly and shifting to the left channel.
    This is really frustrating since never change it manually, and often use my Mac to listen to music/watch films etc. Obviously it's not a big issue to change (done easily through System Preferences) but it would be good to know why it keeps changing in the first place!

  • HT3986 Why does the sound output not work on Windows 7 Bootcamp?

    The internal speakers work fine, but I want to use my surround sound and can't seem to get it to work. It doesn't even work with headphones. Is there an update I need to install or what?

    Alll I can offer is what I bookmarked, that you can access, other threads, and of course Google and what others have found works.
    A simple instruction manual I can't offer but a few words of wisdom, Apple provides driver to enable a chip or device but that is not the end, just the beginning.

  • Why does Itunes Store bill me extra charges?

    I purchased my Ipad 2 months ago and of course created an Apple ID for Itunes Store.
    This week I purchased 2 iphones. Those are being used on two different computers with Itunes but with the same Apple ID
    Each time they want to download some free applications, I am getting charged 1 Dhs ( I'm living in UAE). I find this very strange as all three equipments have been registred with Apple under my Apple ID!
    I suppose I am not the only person in the world having several Apple devices. If this is the normal procedure by Apple, they make very good money on our back!
    If this is not normal how can I proceed to avoid this constant billing?
    Thanks all in advance for your help

    By the way we tried to register a new apple ID without credit card just as explained elswhere in the discussions but in our Itunes store this option is not available....

  • Why does sqlplus pause?

    I know I've read this in the documentation somewhere, but I can't find it.
    I'm not talking about set pause on ; command, instead I need to know why does your query output in a sqlplus window pause after displaying some records, continue, and on and on when running a long query?
    TIA

    For large resultsets, SQL*Plus fetches the rows in the amount specified by arraysize parameter. It fetches rows, displays those many rows, goes to the db to get next batch of rows and so on...
    If you increase the arraysize, the pauses will be less frequent.

  • Why does 'pacman' produce purely informational output?

    My apologies if this dead horse has already been beaten. A brief search didn't turn up any forum topics that addressed this issue.
    Many Unix programs adhere to the dictum that successful execution should produce no output unless something interesting or surprising happened. The canonical example is running 'ls' on an empty directory.
    'pacman' doesn't follow this design philosophy even if the '--quiet' switch is given.
    # pacman -Syq
    :: Synchronizing package databases...
    core is up to date
    extra is up to date
    community is up to date
    multilib is up to date
    As I understand it, the rationale is the desire to be able to use programs in a pipe. If the output contains purely informational text, then every program that uses that program's output has first to throw away the informational text.
    Of course it's easy enough to quieten 'pacman'
    pacman -Sy | sed '/^:: /d'
    or even
    pacman -Sy | sed '/^:: \|is up to date$/d'
    So, I have a two part question: Why does 'pacman' produce purely informational text and why doesn't the '--quiet' switch really quieten 'pacman'?
    Thanks for any insight.

    I used firefox as an example of the differences between using query and search with and without the '-quiet' switch:

    I think this is how the switch is meant to work. I posted a link to a bug/feature request that deals with a similar issue to what you report here.
    Maybe info about every repo - even if it's up to date - is printed for the sake of consistency?

    What does "extracted channel PDF" mean and why does it continually duplicate on my desktop?  I think it happens when I move a file in Finder to another file and when I copy some web files.  I have to immediately move to trash all the duplications on my desktop.  How do I avoid this on my Mac (Mavericks)?  Thanks for your help!

    What application is set to open PDF files? If you CNTRL click on the file and open with Preview does the problem occur?
    If not change the default application to open PDF files to Preview.
    You can do this by highlighting the file and either use CMD i or Get Info , this will open a window with the info on the file with an option to change the application that opens the file.
    That's all I can think of.

  • Outputting 5.1 Channel Surround Sound from your Mac

    How to output 5.1 Channel Surround Sound from you Mac...

    I have been using my MacBook Pro via HDMI into my pioneer av amp which is set up for 5.1.
    I have been able to output 5.1 audio with Logic Pro and FCPX no issues at all after you setup the audio midi utility for 5.1. This setup is via PCM 5.1 audio not to be confused with Dolby 5.1.
    It works great. If you want to play your edited exported movies from Final Cut Pro x in surround then it gets a bit tricky. I export the movie with FCPX as master video with the 5.1 audio then use HandBreak set to atv3 to encode / compress the video. This is great because handbreak folds the 5.1 into a stereo AAC track and also encodes the 5.1 mix into Dolby 5.1 AC3 track so both stereo and surround tracks are embedded in the movie file. So if you have an Apple TV it will play the movie with its surround track. If you play the same HandBreak compressed movie out of your Mac via hdmi to your surround amp it will only play the stereo track if you are using iTunes or QuickTime  and I believe this is because of copy protect and Dolby license issues. iTunes will play a purchased movie from the itunes store in surround via your Macs hdmi to receiver setup but will only play the stereo track of the movie you exported from HandBreak even though it is set up just like an iTunes movie. To get your HandBreak movie to play in Dolby surround from your Mac all you need is VLC player, then you have to go in and select the Dolby track and the output in VLCs audio settings and bingo your HandBreaked movie then plays out of your Mac in Dolby surround. Once you set your Mac up for 5.1 mixing your amp will show your outputting 5.1 via the mac but again this is PCM audio 5.1 and apps like FCPX, Soundtrack Pro, Logic Pro will work.

    Look, you can build an HD DVD with an SD movie, just as you can build an SD DVD with an HD movie. This is not a bug, it is most likely user error. Apple will not be addressing it.
    Just start over, and ensure you are building an SD DVD by bringing up the inspector for the disc (click on the background in the Graphical tab).
    Make sure SD DVD is selected:
    (If you do the same thing on your ill fated project, you'll see that HD DVD is selected)
    Build your DVD and you'll be fine.
    Patrick
    P.S. You will need to google HD DVD and Blu-Ray if you want to understand the difference between the formats. The reason that DVDSP included HD DVD was that its format was similar to SD DVD's. Blu-Ray is something else entirely.

  • Why does my Apple TV have to frequently reactivate some channels

    Why does my Apple TV have to frequently reactivate some channels, such as HBO Go and PBS and several others that I know were already activated.

    Maybe a software update reset something, maybe the broadcasters require this at intervals, could someone have logged/signed out?  Sorry don't get those channels in UK, but once Netflix made me log in again, others seem ok.
    You could send some feedback if this happens very often:

  • Why does Compressor's HDV output look worse than iDVD's output of same?

    Okay, here's the thing... for weekly updates I've been sending the client outputs via iDVD. And they've honestly looked great. The HDV footage fills the screen and doesn't show any noticeable compression funkiness. But for the screening of the completed first cut I wanted to deliver what I thought would be an even higher quality look (esp since I intended to deliver the completed project mpeg and AC3), so I exported the HDV cut out of FCP via QT and converted it with Compressor's DVD: Best Quality 90 minutes to turn the HDV into SD 720x480 16:9 letterboxed. I then burned it with DVDSP, complete with nice looking menus, etc. And I was shocked viewing the output. The two clips I'd reversed in FCP stuttered, and even a clip with nothing on it was strobing. Plus, close ups showed noticeable compression on the faces. So what gives? Why does it look so much better when I just slammed it out on iDVD? What don't I "get?" I've scoured the books I have and nothing seems to give me a clue.
    Any direction would be greatly appreciated!

    Lightroom uses its own raw converter and its own camera profiles to convert the raw data into an image.  This will never be the same as the camera-manufacturer’s raw image decoding either in camera or using camera-manufacturer-supplied software or any other third-party software.
    Here is a general explanation from a few years ago, that is mostly valid, with the one exception that there are no camera-matching profiles for your brand of camera:
    http://www.lightroomforums.net/showthread.php?1285-Why-did-Lightroom-ruin-my-photo
    The IDC is apparently using camera settings and is clearly sharpening the image and quashing some of the lens-flare, oversharpening in my opinion.
    You can do these sorts of things in LR, too, but you have to tell it to do things, it won’t do this by default. 
    The 2010 and 2012 are related to Process Version not Profile, and one difference between the two PVs is how the toning responds to near clipping conditions.  Your reds are very saturated and near if not actually clipping so it is not surprising that the two raw conversions are not the same.
    Can you provide a link to the raw file, using DropBox.com or similar large-file-hosting-service and maybe someone will give some tips on how to make the LR processing closer to what you’re seeing with the camera-manufacturer version.?
