CHAPTER 2: CAPTURING ■

Duration The Duration icon has both a Mark In and Mark Out icon together. Actu-

ally, it isn’t a button at all. This is Xpress Pro’s calculation of the duration of your clip

based upon the Mark In and Mark Out. If you adjust either Mark In or Mark Out,

the number in this register will change. You can also do direct entry of timecode in the

Duration register. For example, if you have a Mark In and you want the clip to be

20 seconds long, type 20:00. The Mark Out will be calculated based upon your dura-

tion. You can also do this inversely to back-time a clip with Mark Out already entered;

enter the desired duration in the register, and the Mark In will be calculated based

upon the Mark Out minus the duration.

Storage Register The last entry on the Marks register is a temporary storage place for

a timecode number to be used later. You can mark this timecode using the adjacent

Locator button to the left of the register or manually enter the timecode by clicking in

the register and typing in the number.

Go To (Cue) On the Mark In, Mark Out, and Storage registers, there is a button just

to the right of the register with an arrow. Clicking this button will cue your tape to the

timecode that is entered into that register.

Clear Marks Clicking one of the buttons at the far right will clear the timecode from

the relevant register.

Capturing Using Mark In and Mark Out Points

Capturing using marked points offers the convenience of doing two things at once: log

and capture. Although this once was prohibitive on more-expensive nonlinear editing

systems (because of the cost per hour of renting or maintaining the system), it’s pretty

common on less-expensive systems such as Free DV or Xpress Pro.

To capture using Mark In and Mark Out:

1. Find the first frame of the footage to be digitized and click the Mark In button

on the Capture tool.

2. Find the last frame of the footage to be digitized and click the Mark Out button.

3. Press the Capture button at the top-left of the dialog.

The system prerolls the tape to a specified point a few seconds before the in

point, rolls it forward, and begins capturing. After the capture is completed, the system

sends a message that the media has been digitized.

You can also digitize footage with no set out point. Simply click Mark In

and press Record. When you’re sure you’ve captured enough for that clip, press the

Capture button a second time to stop capturing. Similarly, you can set an out point

for your capture (for example, before a timecode break or the tape end) and not

mark an in point by using the Capture button to capture on the fly wherever the

tape is cued.
