Recording with Variable Frame Rate (VFR) (continued)

Overcranking effects

Overcranking produces slow-motion playback, which is frequently used in climax scenes, or for dramatic effects like car chases and action scenes. For example, selecting a recording frame rate of 60 fps when shooting a 24P recording format yields a slow-motion effect that is 2.5 times normal speed. Shooting 720P progressive video will produce smooth and highquality slow-motion.

Furthermore, with 1080i, a slow motion effect of 1.25 can be gained if you set the recording frame rate to 30 fps when recording was performed using 24P, a recording format for specifying the playback frame rate.

With the menu option REC FORMAT set to DVCPROHD/60P (50P), you can use a nonlinear editing system to generate slow motion effects from the resulting footage.

A slow motion effect cannot be gained if SYSTEM MODE is set to 1080-50i and REC FORMAT is set to AVC-I***/25PN.
