If you are running your video editing system with multiple OS X users, you may run into a scenario where you need to grab something from another user’s desktop.  This sounds easy, but the built in permissions of OS X will prohibit you from accessing another user’s desktop. Even with administrator rights, you still will not be able to access another user’s home folder.

If you are like me, you store all sorts of things on your desktop while editing.  For myself,  the desktop is one of my primary workspaces.  I’m always moving items to and from my desktop while editing.  Because of this, I’ve developed a habit of using the shared folder a bit more frequently.  The shared folder is a common area where all users can freely access material. 

This doesn’t sound like a big deal, but imagine if you need to grab an element from another user’s desktop, and you do not have their password.  Worse yet, what if that particular employee or contractor is no longer around?.  You now have no way of logging into their OS X account to retrieve the material.

Fortunately, there is another work-around.  You can enable the Mac OS X root user account, which will allow you to access all the files and folders from another OS X user. The root user account is also referred to as a ‘super user’, since it provides unlimited privileges.  Better yet, until a root user account is enabled, any account with administrator privileges can enable it.

Here are the steps to enable the root user account for Mac OS X.

If you are having problems capturing into your Avid or Final Cut Pro system using a DV / firewire connection, you might want to check the length and quality of the firewire cables that you are using.

I've run into the follow problems that all turned out to related to a firewire cabling issue.

- Bad / Distorted Video Signal
- Missing / Inacurate Timecode
- Dropped frames while capturing
- Audio Pops while capturing
- No Deck Control
- An audio signal with no video signal
- Audio interference
- Audio sync problems while capturing

- Intermittent capturing problems

When purchasing firewire cables, keep these important factors in mind.....

For video professionals it’s important to view your final product the way in the same way that your intended audience will be viewing it.  This means watching your final product on an external broadcast montitor or HD screen.

SMPTE_bars_setup.gifFor NTSC broadcast television engineers use SMPTE color bars that have become a standard for calibrating their equipment.  Since all broadcasters use the same color bars, this will ensure that your production will be sent out the same way to all the various networks.

Color Bars are also useful is you are projecting your final product at a trade show.  You can use the Color Bars at the front of your project to calibrate the projector.

Here are the important steps to remember when using and calibrating your equipment to color bars.......

If you are shooting in one of the progressive modes with the Panasonic AG-HVX200 HD Camera, make sure you pay special attention to the type of progressive mode that you are shooting in. 


Before reading further, this article is only relevant to those of us who are shooting for Standard NTSC playback to video.  This article does not apply to those who are using Apple cinema tools to print back to film.


The progressive format you chose can affect the audio/video sync of your clips after they are ingested into Final Cut Pro.  It also affects the storage requirements.  In particular there are two major differences between 720p and 720pn.  So what is 720pn? What does the 'n' stand for? Read on....
