Playback and Recording 3 Chapter

Starting a Shoot with a Few Seconds of Pre-Stored Picture Data (Picture Cache Function)

The camcorder has a large capacity internal memory, in which you can cache the last few seconds (maximum 12 seconds) of captured video and audio, so that recording starts from a point just before you press the REC START button or VTR button on the lens.

Note

The Picture Cache function is enabled only with the camcorder’s recording mode is set to MPEG HD. When you switch to DVCAM recording mode, the Picture Cache function is forcibly turned off and you cannot turn it on.

Setting the Picture Cache time/Picture Cache mode

To record in Picture Cache mode, you need to turn on Picture Cache mode and set the picture data storage time (Picture Cache time) using the OPERATION menu.

The Picture Cache time determines the number of seconds recorded from the Picture Cache, counting back from the time when you press the REC START button or the VTR button on the lens to start recording. However, the number of seconds actually recorded from the Picture Cache may be shorter immediately after the setting of the VDR SAVE/ STBY switch is changed, and in the special situations explained in the following notes.

Notes

•The contents of Picture Cache memory are unstable for a short time immediately after you select Picture Cache mode or change the Picture Cache time. Therefore, if you put the unit into recording mode by pressing the REC START button or the VTR button on the lens immediately after such operation, pictures just before such operation cannot be recorded.

Also, a certain amount of time is required to actually start recording to a disc immediately after you insert a disc and when the VDR switch is set to SAVE. In these cases, the number of seconds that can actually be recorded from the Picture Cache may be fewer than the specified Picture Cache time.

•During playback or recording review, no data is saved to the Picture Cache memory. Thus it is not possible to use this function to rerecord the last few seconds of material from playback or recording review.

To turn Picture Cache mode on, proceed as follows.
