Reading timecode from source video



On most home VCRs, the tape counter doesn't keep track of specific frames--for example, tape counters on many VCRs reset to zero if you switch tapes or turn the VCR off and on. In contrast, high-end and professional video decks and cameras can record and read timecode to and from a videotape, marking specific frames so that it is possible to accurately locate, edit, and synchronize video frames and the audio track. When capturing video, you usually want to capture the timecode associated with each clip if the source video contains timecode. Timecode is essential if you plan to create an edit decision list and create the final video program on a high-end online edit bay instead of in Premiere. Using SMPTE timecode ensures frame accuracy.

When capturing video with timecode, keep in mind the following:

  • The timecode of a source video is captured when you use device control. (Capturing with device control requires timecode. See Using the Movie Capture window.)

  • With device control, you can use videotape timecode (left) to precisely edit a program in Premiere (right).

  • Timecode is visible only in the tape counter on equipment that can recognize timecode, unless the timecode has been burned-in, or recorded over the picture in a copy of the tape. Most home VCRs cannot read or write timecode.
  • If you plan to capture an entire tape, only the In point of the movie needs to be recognized during capture. Once the In point is recorded, a frame-accurate tape deck will capture all of the following frames accurately. The default Out point is beyond the length of your tape; thus, the entire tape can be captured without setting an Out point.

  • Note: Timecode capture with controllable devices depends on the precision of your tape deck. If your tape deck cannot read the timecode accurately, you may have to calibrate your system or manually assign the timecode to your movie by matching frames.
