Setting up the Capture File
When Adobe Premiere captures video, it temporarily stores the video data in a capture file on your hard disk until you save the video as an .avi file (Audio Video Interleaved). If your hard disk is fragmented, Adobe Premiere may need to seek additional disk space during the capture, which may result in dropped frames.
You can preallocate space on your hard disk for the capture file so that Adobe Premiere does not need to look for additional space as it is capturing data. A preallocated capture file is created in contiguous blocks on the hard disk. Premiere simply reuses the same space for each capture session, so you do not need to rebuild to capture file. You must, however, save the captured data to an .avi file when you finish capturing video; otherwise, your data will be overwritten during the next capture session.
To use a preallocated capture file:
Selecting Preview Options.
Preview options let you specify how you preview movies before you capture them. If your video capture board supports overlay previewing, you can preview a live video signal on your computer monitor. In overlay mode, the source video passes directly to the Capture window rather than being processed by the board. Overlay previewing requires much less processing than does standard previewing.
You can specify the frame rate for previews that you play either before or during capture. Decreasing the frame rate reduces the processing time; increasing the frame rate gives a more accurate preview.
To use overlay previewing:
Choose Overlay from the Movie Capture menu. The check mark next to Overlay indicates that this feature is turned on.
To set the preview rate:
1. Choose Preview Rate from the Movie Capture menu.
2. Select the frame rate when previewing and the frame rate when capturing from the drop-down lists.
3. Click OK.
