Using variable frame rates (VFR)
Standard speed shooting for making commercials and dramas
When producing commercials and dramas to be shown on a TV screen, as in the case of HDTV/ SDTV and other broadcasts, a frame rate of 25 fps (frames per second) is the norm (1x speed).
If you use the settings below, the same kind of playback as when the programs are broadcast can be obtained. Commercials and music clips will be recorded with a high
Recording format

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 25P 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) | (FRAME RATE) |
720P/25P, 720P/25PN | Set to 24 fps or lower.* |
•In the case of the 720P/25P format, the quick motion effect can be obtained by using a nonlinear editing system to process what has been recorded.
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
25P recording format for specifying the playback frames, you can obtain slow motion effects with the speed halved by setting the recording frame rate to 50 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) | (FRAME RATE) |
720P/25P, 720P/25PN | Set to 26 fps or higher.* |
•In the case of the 720P/25P format, the slow motion effect can be obtained by using a nonlinear editing system to process what has been recorded.
*You can select any of 20 recording frame rates ranging from 12 frames per second (fps) to 50 fps. (Page 97)
