Capturing Media with a VTR
You can capture a single clip from a VTR. You can capture on the fly with your in and out points determined by mouse clicks during playback, or be more precise by setting in and out points in the corresponding fields.
A single frame capture, or a frame grab, is the simplest clip input operation. This is useful for extracting snapshot frames for a preview or promotion piece.
To capture a single clip:
Cue up the tape to the frame at which you want to begin capturing.
Do one of the following:
- From the Capture Method box, select Start On Click/Stop On Click.
- Enter clip input in and out points in the In and Out fields.
To begin capturing, click Process.
The timecode field turns green, indicating that capture is in progress. Depending on your hardware configuration, the preview window may go black during capture.
To end the capture at any time, click the cursor anywhere over the preview window.
Depending on your project proxy settings, a post-process may occur, generating proxies for each captured frame. You can see a notification on the process that is taking place in the message bar.
Once all capture-related processes are complete, the clip is saved to the Workspace location that you selected before you entered the VTR Input module.
To capture a single frame:
Cue up to the frame you want to capture using the VTR Transport controls or by scrubbing the preview window.
Click Grab.
The captured frame is saved in the Workspace.
Click EXIT Input Clip to view the captured frame.
If you want to compare the captured frame against the frame in the preview window, load the clip into the VTR Input module and enable split-screen view.
Note: If you notice that the previewed image is different from the captured one, edit the Video Input Delay field found in the Engineering menu and recapture that frame. If the two images now match, the delay is fine. If they do not match, you need to tweak the Input Delay until they do.
