Chapter 3 Recording and Playback Undercrank shooting This way of shooting provides quick motion effects used to present such scenes as the movement of clouds, someone standing among crowd of people, and moves made by martial artists. If, for instance, you have shot scenes using the 24P recording format for specifying the playback frames, you can double the speed of the quick motion effects by setting the VFR recording frame rate to 12 fps. Recording format Recording frame rate (REC FORMAT) 720P/24P, 720P/24PN 720P/30P, 720P/30PN 720P/25P, 720P/25PN (FRAME RATE) Set to 22 fps or lower. Set to 26 fps or lower. Set to 23 fps or lower. • The 720P/24P, 720P/30P and 720P/25P formats provide a quick motion effect when processed using a nonlinear editing system. Overcrank shooting This way of shooting provides slow motion effects used to show car chases as well as action scenes, climax scenes and other dramatic presentations. If, for instance, you have shot scenes using the 30P recording format for specifying the playback frames, you can obtain slow motion effects with the speed halved by setting the recording frame rate to 60 fps. Images in the 720P progressive format will create smoothly flowing slow motion sequences with a high picture quality. Recording format Recording frame rate (REC FORMAT) 720P/24P, 720P/24PN (FRAME RATE) Set to 26 fps or higher. 720P/30P, 720P/30PN Set to 32 fps or higher. 720P/25P, 720P/25PN Set to 27 fps or higher. • The 720P/24P, 720P/30P and 720P/25P formats provide a slow motion effect when processed using a nonlinear editing system. Shooting in the 1080i/480i Progressive Mode Selecting 30P, 24P or 24PA (1080i or 480i mode) in the REC FORMAT in the setting menu RECORDING SETUP screen enables shooting in the progressive mode. ■30P mode This mode enables shooting 30 fps video in the progressive mode. The 30 fps video signal is converted to a 60-field interlaced signal for output and recording. • This guarantees high-quality video output. ■24P mode This mode enables shooting 24 fps video in the progressive mode. A 2:3 conversion format is used to convert the 24 fps video signal to a 60-field interlaced signal for output and recording. • This guarantees a cine-like video output. 24P A B C D E F G H 60i Ao Ae Bo Be Bo Ce Co De Do De Eo Ee Fo Fe Fo Ge Go He Ho He ■24P advance mode This mode enables shooting 24 fps video in the progressive mode. • The advance mode converts a 24 fps video signal to a 60-field interlaced signal for output and recording. 24PA A B C D E F G H 60i Ao Ae Bo Be Bo Ce Co Ce Do De Eo Ee Fo Fe Fo Ge Go Ge Ho He • As shown in the illustration, the conventional 24P (2:3) conversion system for editing extends the BoCe, CoDe, FoGe and GoHe fields into adjacent frames, which causes a drop in picture quality. • By contrast, the 24P advance conversion system drops the BoCe and FoGe fields to produce video of higher quality. Using an editing system that is compatible with advanced conversion will help to produce better video quality than the normal 24P mode. • Use the normal 24P mode when working with other editing systems. The following applies to shooting in the progressive mode. • A gain of 18 dB cannot be used. • Set the shutter speed to 1/50 (OFF) or to 1/60. • There may be a slight delay at the start of recording when shooting in the 24P or 24P advance mode because 5 frames are recorded at a time. 30P A B C D E F G H I J 60i Ao Ae Bo Be Co Ce Do De Eo Ee Fo Fe Go Ge Ho He Io Ie Jo Je 39 Variable Frame Rate (VFR) Recording
