Chapter 3 Recording and Playback — P2 card

Dividing clips recorded on P2 cards

If P2 cards of capacity 8 GB or greater are used on the camera, recording is automatically continued as another clip when a single continuous recording time exceeds the times in the table below. Also, when thumbnails for clips are handled (displayed, deleted, restored, etc.) on P2 devices, they can be handled as a single clip. Clips are sometimes displayed as separate clips in nonlinear editing software and on a computer.

How to handle data recorded on P2 cards

P2 cards are semiconductor memory cards that are used as the recording medium in the professional video production and broadcasting devices that make up the DVCPRO P2 series.

ffSince data recording in the DVCPRO P2 format or AVC‑Intra are in a file format, they have excellent compatibility with computers. However, the file structure is a unique format, which in addition to video and audio data in MXF files contains various other important information items. The folder structure links the data as shown below.

-Do not transfer individual files from the CONTENTS folder.

-When copying, copy the LASTCLIP.TXT file at the same time as the CONTENTS folder.
