John: May 2011 Archives

If you work with multiple user accounts on your editing system, what happens if you forget the password for one of the users?

This becomes a problem is that particular user has left critical files on the desktop.

Even an administrator will not be able to access the other user's desktop.

Fortunately, you can activate the 'super user' or 'root' account.

You'll then be able to retrieve data from that particular user's desktop.

The solution in the past has been to format all your drives as FAT 32.  However, that causes a problem if you need to copy large files. Fat 32 has a file size limitation of just under 4GB. 

After the software driver has been installed, you can use the standard Mac OS Disk Utility to format your devices as NTFS.  You can even create NTFS disk images.


The company that offers the software is called Tuxera, and they offer a 15 day trial version of NTFS for Mac.  Software licensing starts at roughly $35.00 for a single license which seems fair.


This is excellent, because I'm sometimes in a situation where a student wants me to copy some media or tutorials to their drive, but it's formatted as NTFS.

Here's a short tutorial on how to create the 'Pleasantville' effect using Apple Color's software.  Apple Color is included within the Final Cut Studio package of software products.

I recently attended the 'unveiling' of Final Cut Pro X, and it appears that Apple has integrated the major features of Color within the next version of Final Cut Pro.  It will be interesting to see what happens to Apple Color.  My guess, is that it will be at the end of its life after Final Cut Pro X ships.

For what it's worth, here's a great tutorial on using Apple Color to isolate and shift a particular color.  Enjoy!
Check out this short tutorial that demonstrates how to re-format your old 4x3 media so it mixes or fits with your hi def 1080i media.
ProRes is becoming a standard file format for professionals who use Final Cut Pro.  The latest version of Final Cut Pro currently offers 5 flavors of ProRes.  The set of Apple ProRes codecs provides all the necessary data rates for most professionals.

ProRes 422 has a data rate of 145 Mbps.

Data Rates for Pro-Res is measured in Mbps. So, what exactly does Mbps mean?  How does it relate to 'real-world' storage requirements for the 'non-geek'?

For starters..... 1 byte equals 8 bits of data.  Hence, that's why everything works with a base of 8 in terms of computer processors.  8 bit processing, 16 bit processing, 32 bit processing, and so on......

Mbps:  stands for 1 Megabit per second, and 1 Megabit is 8,000 bytes.  This also means that 1 MBps (megabyte per second) = 8 mbps (megabits per second). 

Whew! make sense?  Don't worry.

Honestly, talking in bits and bytes starts to make my head spin.  I personally tend to think of things in terms of Gigabytes and Terabytes.  If you're like me, you want to know how many minutes of ProRes storage will fit on your new 500GB, or 1TB drive.

So here it is:  A one terabyte drive will hold roughly 1,000 minutes of ProRes 422 media. Yes, that's pretty easy math!

or 500 Gigs = 500 minutes.  Got it?

However, this calculation is only an approximate.  The amount of storage will also depend on things like the number of audio tracks, and image complexity when it's being encoded into ProRes.

However, if you are curious how to get to that number, here's the math:

With the announcement of Final Cut Pro X, you will soon see workflow changes for those who currently own Final Cut Studio. 

In particular, Final Cut Pro X will incorporate software features that are available in Apple Color.  In the meantime, please enjoy this tutorial that demonstrates features in Apple Color and Motion.  This tutorial was previously a 'rental' video, but GeniusDV has decided to release the video for free.
