Profile Family 131
To convert clips or masters:
1. Select one or more clips or masters that you want to transcode in Media
Manager’s contents pane.
2. In Media Manager, choose Tools | Transcode . The Transcode Utility dialog
box appears with the selected media in the transcode list.
3. You may add more clips or masters to the transcode list by dragging them
from Media Manager and dropping them on the list. You can also transfer
media using
Copy and Paste commands.
4. In the Convert tab, select the target format, either MPEG or JPEG.
5. In the Video Quality box, select a video quality if you want something other
than the default (Medium). The higher the quality, the more disk space is
used.
6. To change a custom quality setting, click the button next to the Video
Quality list box, and the Custom Video Quality Settings dialog box appears.
Select either
Custom1 or Custom2 in the Video Quality list box. When
selected, you can change the name of a custom setting. Click Undo to cancel
changes and OK when done.
- For JPEG (see Figure 58 and Table 6) select a video quality with the
slider. You can move the slider with the mouse or arrow keys.
- For MPEG (see Figure 59 and Table 7) select a chrominance value, either
4:2:0 or 4:2:2 . Then move the diamond on the grid or click the High,
Medium, Low, or Draft button—the corresponding bit rate and picture
structure is shown on the right side of the dialog box.
NOTE: You can edit I-frame clips only. To make an MPEG clip I-frame,
drag the diamond to the far left side of the grid.
