Locking to external timecode: crossing midnight problems

Hello,
last weekend I was doing a recoding for a DVD.
My Logic setup was sync'ed to video using both wordclock (48kHz) and SMPTE TimeCode (via MTC). Timecode was sync'ed to the realtime clock in Frankfurt.
Now, since the recoding a whole lot longer than foreseen, timecode went from 23:59:59:24 to 00:00:00:00. Apparently Logic didn't handle this too well and just stopped in the middle of this live event!
Now, while I understand that this phenomenon is well-known (and is called midnight crossing), I was wondering if there is any way to avoid this problem for future events?
All help very much appreciated! I love Logic and really want to keep on using it, even though I know that PT and Reaper can handle this problem blindly...
Greetings,
Bert

hi,
Try using a second SMPTE generator, with an offset. this way you can set it at 1 hour, being that the start of the project, and reference the 1 hour to the "real" SPMTE on-site. just note when the 1 hour SPMTE starts in relation to the local SMPTE time.
It's easier than it seems, and guarantees you can go for 23:59:00:00 before encountering the midnight crossover issue.

The TCP-50 does this offset output.

  • DVD authoring problems since adding external drive-coincidence or problem

    I've connected an external drive to home unit to store footage. I feel this external is a little slow compared to my Mac but not sure how to find out.
    Anyway, I create mpv files for DVD authoring. Same process as always EXCEPT the external housed footage. Build DVD as always. Now my boss has these DVD locking up or pixelating. Yet, if she plays an older disc it still works fine in her system. Her other DVD player sometimes does not recognize the disc. I've even created the mpv files and went to FT work to build the disc. It eliviated the problem but did no cure it.
    This problem does not happen on all discs.
    All these problems happened with the very next disc and almost all the discs that have been involving the external. Coincidence or problem.
    I intend on getting a LaCie external to use. We use them at FT job and never a problem. But until then:
    I'm thinking of creating a QT file on the Mac hardrive and then compress.

  • External Firewire Hard Drive Problem

    I have an external Maxtor FW 400 drive with two partitions that I've been using for backups. I've been using it with my iMac. Last night I kept having to force-quit different apps and finally decided to restart. My computer wouldn't shut down all the way and I had to finally use the power button. When I tried to start back up, I couldn't get past the grey screen. I kept having to use the power button to shut down. I disconnected everything but keyboard and mouse and did the reset SMC. I've zapped the PRAM. I couldn't get the disk to mount at all on my iMac. I used the disk utility on the iMac and 4-5 things came up when it did the verify/repair disk. I also did the hardware test and no problems were found.
    I decided to try it with my MBP and finally one partition mounted, but the other didn't. I tried the disk utillity and get errors when I try to verify and repair. I was able to copy some of the files from the partition that mounted onto another drive, but some of the folders are giving me an error.
    I've read some about DiskWarrior. Is that something that might help to repair the disk so I can at least get the files off? I have a copy of Tech Tool Deluxe that I got with AppleCare for an iMac G5, but don't know if that would help or not. Haven't been able to get it to work though. When I try to start up from the CD, I'm pressing C as I start up but it's not doing the CD. I know the version on the CD isn't for Leopard, so that might be why it's not starting up from CD? Does anyone have any suggestions about what might help?
    Also, I guess I may have to purchase another external hard drive. This was a Maxtor about 5 years old. I've had a WD My Book USB also go bad on me, so I've stayed away from those. I have a SimpleTech USB that seems okay so far. I use a Time Capsule for my Time Machine backup. But, I'm creating a lot of video and photo projects so I have some really large projects and fill up a drive fast. They're too big to fit on a DVD. You need backups of your backups. How do y'all manage you big projects?
    Lots of questions. Would love some answers. Thanks!

    So is that iMac G5 working fine with off its internal drive? Only the external is causing this problem?
    The copy Tech Tool Deluxe will boot your iMac G5, but it probably will not boot the MacBook Pro (because it is Intel and that old disc is probably for PowerPC). So if you want to use it, you will have to use the iMac G5 to boot it. It does have a volume repair function.
    Disk Warrior, and the complete Tech Tool Pro, as well as Drive Genius (from Prosoft), are all utilities that can do repairs beyond the capabilities of Disk Utility.
    For external drives, I tend to buy an external enclosure that I like and then look for a good deal on a hard drive to put inside it. I usually buy the enclosure from a company that is focused on Mac users, such as OWC (macsales.com) and Macally. They (and others) sell empty cases. At this point, I would buy a case that has both USB 2.0 and FireWire connections. As for the hard drive itself, I like using dealmac.com for links to great deals.
    I recently had a need for a large amount of extra storage to use with Time Machine. The cheapest way I could find to add the space I needed was to get 750 GB Western Digital Green SATA drive ($70 deal found through DealMac) and connect it to USB 2.0 using one of these adapters.
    http://eshop.macsales.com/item/Newer%20Technology/U2NV2SPATA/
    I know I'm wasting the speed capability of a new SATA drive, but USB 2.0 is fast enough for using with Time Machine. It just sits as a bare drive next to my iMac and my FireWire external drive. Because the "green" drive is probably operating at a slower speed, it makes almost no sound and barely gets warm.
    At MacWorld this year, OWC's booth was showing off this device called +Voyager Q+.
    http://eshop.macsales.com/item/Newer%20Technology/FWU2ES2HDK/
    With it, you plug in regular bare SATA hard drive mechanisms like those old Iomega cartridge drives. If you are regularly running short of storage space, you might consider this type of solution as a way to have essentially unlimited storage without the need to have a clutter of external drives, each with its own cable, power cord, and power supply. Just have a safe place to store your archive of SATA hard drives and plug them in as needed.

    Sending by Dropbox where, To who, to what computer? As your does not start up.
    You need to take at least the OS disc to a work Mac computer and create DMG from the OS install disc then restore that DMG to USB thumb drive. Then you can boot the computer from that thumb drive and install the OS. That is if your hard drive is functioning correctly.
    Then you can use the App disc in the external CD/DVD drive to load up all the included Applications that come with your version of OS X.

  • Need help with Rollover Image cross browser problem

    Hello,
    I am having a cross browser problem with my websites rollover nav links.  The trouble is, while they work perfectly fine in IE8 and IE9, I’ve also attempted to use them through Opera, and they simply don’t work.  They don’t link nor do they do their rollover effect.  And I was trying to figure out what I have done wrong.  Currently the site is not completed, but the first two pages are, the “news” and “about me” pages are currently (as of right now) working.  The address to the site is below.
    http://maxmetal.xsustudios.com/index.html
    I hope that someone can help me with this, if needs be I can put the code for the CSS and HTML into this part if it will save some time for everyone.  Sorry too about the PNG images, I have to change those over to semi-transparent GIF’s yet so the site does take a while to load…
    Hope someone can help me with this!

    When I disable CSS in my browser, the rollover buttons work just fine.  This tells me your CSS is messed up and you've layered something over your menus which is making them inaccessible to users.
    I noticed you've applied relative positioning to just about everything on your page.  Why?   Default CSS positioning (unspecified or static) is all you need for 98% of layouts.

  • Changing BEx query - Lock against External Changes

    I have BEx query in DEV system.
    It was transported to QA system.
    Now some changes were made in Cube, Like adding infoobjects.
    These infoobjects are to be available in BEX query.
    But when the query is opened the following message is getting display
    Lock Against External Changes...
       BEx transport request 'DV1E756532' is not available or not suitable
    After checking details of message
    Diagnosis
    There are the following possible causes:
    No request has been set up as the standard transport request for BEx objects.
    The (set up) request 'WD1K917646' (for the package '' ) has already been released.
    The (set up) request 'WD1K917646' (for the package '' ) is not of the type 'transportable change request'.
    System Response
    The request WD1K917646 can not be used to record changes to BEx objects (queries or Excel workbooks). The changes made to objects you are editing will not be logged.
    Procedure
    If you want to record changes to BEx objects, set up an open transportable change request as the transport request for BEx objects. (If the package '' is not empty, set up a request for this package).
    Inform your system administrator of your actions, or enter a new, targeted transport request in the Administrator Workbench in the transport connection by using the 'BEx' pushbutton (Create Transport Requests for BEx).

    How to make changes to query.
    Step by Step help needed.

    Hi,
    I'm also receiving similar error 'BEx transport request is not available or not suitable' when I open a query in development SYSDEV to edit.
    This query has been transported to SYSQA but now I need to make some changes so I opened it in  SYSDEV but it doesnt allow me to edit.
    Do I need to follow the below steps to be able to edit the query in SYSDEV and once done I need to transport the changes/query to QA for validation.
    In SYSDEV or SYSQA ?
    Step 1) Go to RSA1 Tcode.
    Step 2) Click on "Transport Connection" function on the left side pane.
    Step 3) Make sure that Grouping is "Only Necessary Objects".
    Step 4) Make sure that Collection mode is "Collect Automatically".
    Step 5) Collect your query by double clicking on "Selected Objects" which is under "Query Elements"->"Query"->"Selected Objects".
    Step 6) On the Right side pane, take a Right Click on the "Query Elements" node and choose "Transport all below".
    Note: Make sure that you have not selected any other object other than the objects which are under "Query Elements".
    Step 7) Click on the "Transport Objects" ( Truck Icon ) button. Is it Transport Bex button here ?
    Step 8) Create a new "Transport Request".
    Also below are the steps I used to transport from SYSDEV to SYSQA initially.
    Step 1) Go to RSA1 Tcode.
    Step 2) Click on "Transport Connection" function on the left side pane.
    Step 3) Make sure that Grouping is "Only Necessary Objects".
    Step 4) Make sure that Collection mode is "Collect Automatically".
    Step 5) Collect your query by double clicking on "Selected Objects" which is under "Query Elements"->"Query"->"Selected Objects".

    Step 8) Create a new "Transport Request".
    Please advice
    Thank you.

    Is it something like a cross-domain problem?

    It looks like I've solved it. The parent domain was

  • Could USB external HD be the problem?

    For several days I've been concerned because no matter what steps I took, the 10.5.6 upgrade was exhibiting buggy behavior. Programs didn't shut down correctly or at all, programs didn't behave correctly, the system itself wouldn't restart (it would clear the icons off the desktop and then hang in the restart necessitating a hard shut down/power up.)
    I went through an archive/install, then applied the combo 10.5.6 updater. Before and after the process, I repaired the disk using DU and repaired permissions. No problems found.
    Through trial and error, I discovered that whenever my external 500mb Iomega hard drive was connected and turned on that that was when my iMac exhibited all the odd behavior. If the drive is turned off, the iMac behaves normally. I did run disk repair from DU on the external drive and no problems were found. After doing so, the problem with the iMac wasn't fixed. I had to manually shut down, turn off the external drive, started the iMac again and the iMac behaves normally. So (I think) I've isolated the problem to the external Iomega hard drive.
    Questions: (1) has anyone else experienced this problem and, if so, what did you do about it? (2) Does this sound as though the external HD is shot despite what DU is saying after running the disk repair routine? (3) Any other ideas as to how to proceed? I use the external HD for my backup routine.
    Thanks and sorry for the long post.

    Hi rk:
    You have been VERY thorough in your troubleshooting. Thank you for the complete documentation as well (that prevents me from suggesting things you have already tried).
    The A&I and the combo updater "should" have completely addressed software issues.
    If you have not done so, run the hardware checker (extended test). That could reveal a hardware issue.
    If you have it, +"tech tool deluxe"+ also checks all sorts of things - including USB hubs.
    If you have a way (an Apple store, perhaps) you might take the external drive to that location to hook it to another Mac to see if it causes problems there as well.

    The screen could not rotate automatically while without lock it, how to solve this problem?

    If there isn't a lock symbol at the top of the screen next to the battery indicator then try a soft-reset and see if it rotates after the iPad has restarted : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

  • External HDD - Standyby / Sleep Problems

    Hi everybody,
    I use a TC 1 TB, connected to my MacBook using Gigabit Ethernet. The TC is connected to automatically on startup and everything works fine.
    As soon as I connect an external USB harddisk to it, I encounter problems when starting the system or waking it up from standby / sleep. It seems that the exernal harddisk enters sleep mode, too, and the TC is not able to wake it up properly. Thus, the startup process hangs, i. e. the MacBook can't be used. When I disconnect the HDD from the TC, things continue smoothly.
    Does anyone have any ideas how to solve this issue? I'd really like to use the external HDD as additional space.
    Thanks in advance!

    Depends on hard disk type used. Change of externalö disk solved the problem.

  • Format/cross-compatibility problems with Seagate External HDD

    I recently bought a MacBook Pro (July 08) and as soon as I took it out of the box and set it up, went to plug in my little 120GB Seagate HDD to dump the files onto my new Mac, and received the query "Do you wish to format HDD?" Of course I clicked 'NO', and ejected the drive from the Mac. I went to plug it back into my old PC (where it had worked moments before) and received the same query as on the Mac, plus, when I went into properties, found that the drive was no longer FAT32 but RAW. I now find myself at wit's end trying to rescue the 4 years' of data on the drive. I have tried running disk utility on Mac where it can see it still as FAT32, but can't mount it or repair it, and it's still in RAW format when connected to PCs. Anybody out there with some ideas?
    Thanks!

    I'm not a hardware expert, but Seagate had a major HD firmware issue earlier this year:

  • Library locked on external drive

    Hi,
    I was using the Aperture on a PowerBook 17" laptop without problems. I was running out of space and copied the aperture library file on an external USB drive. It worked fine for a couple of weeks but than, after one import from my D200 stoped in the middle of transfering files, I received the message that the database is "locked". I looked at the file with the command-I key and the "locked" box is not checked and I do have read and write permision on the file. I copied the file back to the internmal HD (it takes forever for this 44GB file) and ran the disk verification and permisions on it: all fine with no errors given. I can read this file on the internal drive with no problems. I subsequently tried to copy this file on 3 other external disk drives and they all give me the errer message that the file is "locked". I am really at a loss: the Aperture library file can be read without problems on the internal drive but not external drives. I used the vault feature being afraid I will loose a few thousand picutures. I gave me some errors re. few projects: it could not back them up. This was not a problem before. I called Aperture Apple support and they were not very helpfull: they informed me that they had this problem "rarely". The fellow provinding customer support instructed me to delete the preference file in the "Preferences" folder pertaining to Aperture, create a new Aperture file to see if all works well (which it did) but did not solve my problem of "unlocking" the database on external drive where I would like to work with it since I am out of space on my laptop.
    Did any of you had this problem? This could be a major shortcomming for this program if it locks your DB and can't unclock it. I should also mention that when I click the "loced" tab on the information pannel, the tick mark flashes but nothing happens.
    Any help that will result in solving this problem will be appreciated.

    Bear in mind that Time Machine will apply ACL's (extended permissions) to the backup disk so it may be completely normal to be unable to access files on that disk. If you are trying to use an iPhoto library inside the backups folder it may not work at all - it must be copied off to another disk to use with iPhoto.
    With that said, if the disk is failing or damaged it may not mount in Finder - is that what is happening here?
    It is also possible that the failure is the 'external case' and not the actual disk, if the controller is not working the disk may not mount - sometimes you can get a disk to work by using a different external case or a USB toaster
    You will need to consider data recovery if the disk is on it's last legs or is corrupted. Frankly this is complex & you should send it to data recovery professionals if you are inexperienced - it is the best way to stand any chance of recovering data on a failing drive, but it is costly. You are also correct to se the disk as little as possible - if the damage is a mechanical issue reading the disk can cause the disk to fail quicker.
    If you are intent on doing data recovery yourself you must get another disk that is larger than the disk you need to repair. Then you can use tools like Disk Warrior or or Disk Drill to repair the disk or recover the files.
    Provide more info about where the library is & the state of the disk, you may not need to do recovery.
