■ CONSIDERATIONS BEFORE YOU CAPTURE

Allotting Proper Drive Space

Before you begin any project, you’ll need to make sure that you have enough drive

space to hold all the media that you create (see Figure 2.1). In addition to captured

footage, you’ll need space for rendered effects. There’s nothing worse than being in the

throes of postproduction, only to find that you have no more space on your drives. It

can happen, and the results are not pretty. However, when it does happen, you have

the option of deleting unnecessary files or purchasing, maybe even renting, additional

drives for the project.

Figure 2.1 Checking for drive space with the Capture tool

Back when Small Computer System Interface (SCSI) drives were the only option

for Avids, your only real alternative when running out of space was to rent drives,

mostly because SCSI drives were so expensive. In 1993, I purchased 21 gigabytes of

storage for a whopping $21,000. Now they’re boat anchors. Fortunately, we have

FireWire drives today, so drives aren’t as costly. Drive space is always a good thing to

have around, especially if you work on projects with high shooting ratios, such as

documentaries.

Note: What’s a shooting ratio? If you aren’t familiar with the term,a shooting ratio is the amount of

footage shot versus how much is actually used,For example,if you shoot 30 hours of footage for a 1-hour pro-

gram,it is said to have a 30:1 shooting ratio. Because of the cheap cost of DV tapes,many DV documentaries

have as much as 50:1 shooting ratios.Some even go as high as 100:1.By contrast, low-budget films shot on

16mm film can run as low as 12:1.Some television programs run less.And those crazy reality TV shows shoot

using motion detectors around the clock,so you might find several hundred hours just to see who gets kicked

off the island this week.
