Recording and Playback Normal Recording REC START/STOP button or VTR button at the lens starts recording of video and sound on the P2 card. A cluster of data that consists of video and sound generated through a shooting action, together with such added information as meta data, is called a "clip". Normal Recording and Native Recording In the unit, the camera's recording method is selectable between the native recording method with the frame rate unchanged and the normal recording method pulling the frame rate down to 59.94 or 50 frames. Normal recording (Pull-down recording) Images at 24P (23.98P: referred to as 24P) are pulled down in 2:3 mode. Images at 30P (29.97P: referred to as 30P) are pulled down in 2:2 mode and recorded as 59.94i or 59.94P (referred to as 60i and 60P). Images at 25P are recorded as 50i or 50P with 2:2 pulled down. 1080i supports 24PA (2:3:3:2 Advanced Pull down) as well. AVC-Intra does not support pull-down recording. Example of 24P Over 60i Camera recording A B C D 2:3 pull down = Ao Ae Bo Be Bo Ce Co De Do De recording Native recording This recording method extracts and records effective frames at the frame rates of the AVC-Intra recording in 1080i, and DVCPRO HD and AVC-Intra recording in 720P. For 720P, it is possible to record images where the length is 2 to 2.5 times longer than the pull-down recording. Even in native recording, the rate for outputting camera images and playback images is 59.94 or 50 frames that are pulled down.

Therefore, the time code may be discontinued when recording clips continuously in another mode in which the recording cycle is different. Even if a P2 card has just been inserted, or the power has been just turned on, you can start recording using the internal memory of unit. In this case, recording cannot be stopped until the P2 card is recognized. If the inserted card is not recognized as a recordable P2 card, the record in internal memory is instantly discarded, and the a b message "CANNOT REC" is displayed on the viewfinder. Press the MODE CHECK button to check P2 card status (displayed in viewfinder). a. REC START/STOP button b. MODE CHECK button 35 Recording and Playback: Normal Recording
