Recapture clips
You can recapture clips in an existing project using batch capturing. Clips can be recaptured only if they have been
unlinked from their source files, becoming offline clips; if they have names in their Tape Name fields; and if their
source medium contains timecode.
1 If you want to override the capture settings for any clip that you intend to recapture, set the clip’s Capture settings.
2 In the Project panel, select all the clips you want to recapture. If you want to select clips in different bins, use List
view, which lets you view multiple bins.
3 Choose Project > Make Offline. The selected clips are dissociated from their current source files.
4 In the Make Offline dialog box, specify whether the source media files are to remain on disk or be deleted.
5 With the offline clips still selected, choose File > Batch Capture. Adjust the settings as necessary.
6 Verify that the deck and source videotape are set up properly for capture, and then click OK.
7 After recapturing is complete, save the project.
Timecode
About timecode
Many camcorders and high-end video decks record timecode, which marks specific frames with unique addresses.
Timecode is important whenever you want to capture exactly the same frames that were identified or captured
previously, as in the following tasks:
• You want to log clips before you capture them.
• You plan to capture clips using batch (automated) capture.
• You want to recapture clips because the original files became corrupted or were deleted.
• You plan to export sequences to another system by using EDL.
• You’re using a system in which you edit quickly with low-resolution captures, and later recapture the clips at full
resolution and quality for the final version.
• You plan to synchronize captured video with audio recorded separately.
Unlike the numbers on time counters found in home VCRs, timecode is recorded onto videotape as part of the video
signal. If footage lacks timecode, you can add it by copying it with a camera or deck that writes timecode. You can then
log or capture the video from that device.
For best results, timecode should run continuously from the beginning to the end of the tape; it shouldn’t restart from
zero anywhere in the middle. In editing, if you log a capture In point such as 00:00:01:09 but that number occurs on
the tape two or three times because of timecode restarts, Premiere Pro can’t be certain which 00:00:01:09 is the place
to start its capture. It can easily capture the wrong clips from tapes with discontinuous timecode.
To ensure unbroken timecode, you need to either shoot it continuously or stripe your tape with it before shooting.
To ensure that you always shoot continuous timecode, record at least 5 seconds of extra video past the end of the action
in any shot. If you review a clip in the camera, be sure to rewind the tape back into that 5-second margin before
recording again. Your camcorder reads the timecode from the frame on which you stop and begins recording timecode
with the very next frame number when you start your next shot. Be careful; if you leave a gap between the last frame of
the previous shot and the first frame of the next, the camcorder begins writing timecode at 00:00:00:00 again.
