Chapter 4. Capturing and Importing Media > Configuring Your Hard Drives for Cap...

Configuring Your Hard Drives for Capture

The first capture-related settings you should check before using the Capture tool to capture (record) footage are those that relate to choosing your media drives.

You should have more than one hard drive connected to your computer so that you can capture to a designated media drive rather than to the same drive that contains your operating system and Xpress Pro application. If you capture to the drive that contains your OS, performance lapses may occur. Xpress Pro includes a feature for filtering out your system and launch drives to help you avoid this problem.

If you have more than one media drive available, you can create a drive group. If you use a group, you can instruct Xpress Pro to automatically start capturing to another drive in the group if your initial capture drive becomes full.

To choose your capture drives:

  • Go to the Capture tool's Bin section and do one of the following:

    • To capture video and audio to the same drive, click the drive selection pop-up menu and choose a drive name.

    • To capture to a group of drives, click the drive selection pop-up menu and choose Change Group. In the dialog box that appears, Shift-click to select the drives you want to belong to the group and then click OK (Figure 4.2).

      Figure 4.2. If you have more than one drive available for capturing media, you can include those drives in a drive group. Then if you select Switch to Emptiest Drive When Full in the Capture Settings dialog box, you don't have to worry about switching capture drives when one drive in the group becomes full.


    • To capture video and audio to different drives or drive groups, click the Single/Dual Drives mode button next to the drive selection pop-up menu, so that two drive selection menus now appear. Choose your video drives from the first menu and your audio drives from the second menu.

    Now when you capture video and/or audio with the Capture tool, Xpress Pro will create audio and video source media files (usually OMF files) on your selected drives.

✓ Tip

  • You can also choose your capture drives by opening the Media Creation settings dialog box and clicking the Capture tab. Then choose your capture drives as you would when using the Capture tool (Figure 4.3).

    Figure 4.3. You can also designate capture drives in the Media Creation settings dialog box.


To avoid capturing to your system and launch drives:

1.
Open your active Media Creation settings by double-clicking the settings name on the Settings tab of the Project window or by choosing Tools > Media Creation.

2.
In the Media Creation settings dialog box, click the Drive Filtering tab and select Filter Out System Drive and Filter Out Launch Drive (Figure 4.4).

Figure 4.4. If you do not want to capture to the drive that contains your system folder or your Xpress Pro application—and you should especially avoid capturing video to those drives—you can filter out those drives in the Media Creation dialog box.


From now on, Xpress Pro will not capture video or audio to your system drive (the drive containing your operating system) or launch drive (the drive containing the Xpress Pro application).

✓ Tips

  • Selecting Filter Based on Resolution is relevant if you are using Mojo and are capturing 1:1 (uncompressed) video. Xpress Pro will filter out any Avid manufactured drives that don't support such a high resolution.

  • In the Media Creation settings dialog box, you can apply your drive selection settings to all other capture and import operations by clicking the Apply to All button.


To set hard drive data limits for capture:

1.
On the Settings tab of the Project window, double-click your active (check-marked) Capture settings.

2.
In the dialog box that appears, click the Media Files tab (Figure 4.5) and set a file size limit by selecting one of the following:

  • Capture to a Single File, 2 GB Limit: This is the normal option to select, as long as you're not capturing clips that are more than 2 GB in size (for DV, that's just over 9 minutes). For each source clip you capture, Xpress Pro creates a single video and/or audio OMF file on your selected media drive; Xpress Pro will limit the size of the source media file to 2 GB.

  • Capture to Multiple Files: Use this method if you plan to capture clips that will result in source media files larger than 2 GB. For each source clip you capture, Xpress Pro creates multiple video and/or audio OMF files across multiple media drive partitions. To determine the time limit for a source clip captured in this manner, enter a number of minutes in the Maximum (Default) Capture Time box. To use this option, you must create a drive group of two or more drives.

Figure 4.5. Use the Capture settings dialog box to set either a file size limit or source clip time limit for capturing. Also use this dialog box to ensure that Xpress Pro always leaves a buffer of extra space on your capture drives.


3.
If you always want to leave a buffer of extra data space on your capture drives, select Switch to Emptiest Drive When Full and choose a number of minutes from the adjacent pop-up menu.

As long as you have configured two or more drives to be part of a drive group, Xpress Pro will capture to the next available media drive when it reaches the set limit. Leaving a buffer of extra space on your media drive decreases the risk of playback problems.

✓ Tip

  • If you change the default (30 minutes) in the Maximum (Default) Capture Time box, Xpress Pro requires a lot of time to reallocate the number of minutes set for capturing on your drives.
