Variable frame rate (VFR) recording function/super slow recording function

It is possible to acquire smooth slow motion or quick motion video by shooting with a different frame rate from the frame rate to play back.

Variable frame rate (VFR)

Super slow recording function

Variable frame rate (VFR)

Allows the high-speed shooting from 2 fps to maximum of 60 fps.

character_diamond Frame rates during actual recording

There is a slight variation in the frame rate displayed on the screen and the frame rate that is actually recorded.

Recording is with the following frame rates: (frame rate displayed on the screen (frame rate actually recorded))

When the [SYSTEM] menu [FREQUENCY] [59.94Hz] is set

2fps (2.00 fps)	12fps (11.99 fps)

This allows high-speed shooting of 120 fps/100 fps.

In [SYSTEM] menu [FREQUENCY]/[FILE FORMAT]/[REC FORMAT], select the resolution, codec, and base frame rate for recording images.

Select the following items.

This can also be set even with the USER button. ( character_reference Assigning functions to the USER buttons)

Press the REC button.

Super slow recording starts.

character_diamond Frame rate and effect

The slow motion effect during playback changes depending on the frame rate of the [REC FORMAT].

Frame rate of [REC FORMAT]	Slow motion effect during playback
59.94p, 50.00p	1/2 speed
29.97p, 25.00p	1/4 speed
23.98p	1/5 speed

character_diamond Frame rates during actual recording

When [SYSTEM] menu [FREQUENCY] [59.94Hz], there is a slight variation in the frame rate of super slow recording and the frame rate that is actually recorded.

Screen display	Frame rates during actual recording
[S.SLOW120]	119.88 fps

(Variable frame rate recording/super slow recording)

In the following cases, this cannot be set.

– When set to an item that does not support [FILE FORMAT] or [REC FORMAT]

– When using the face detection/tracking AE&AF function

The [CAMERA] menu [SW MODE] [AF SPEED] and [AF SENSITIVITY] will operate in [0].

The [RECORDING] menu [TC/UB] [FREE/REC RUN] is fixed to [REC RUN].

The following functions are canceled.

– Dynamic range stretcher function ( character_reference Dynamic range stretcher function)

– Flash band compensation function( character_reference Flash band compensation (FBC) function)

– Pre-recording ( character_reference Pre-recording)

– [2 SLOTS FUNC.] ( character_reference Relay recording to Dual codec recording [X2])

– Interval recording ( character_reference Interval recording)

– [HYBRID O.I.S.] ( character_reference Switching enable/disable of the hybrid optical image stabilizer function)

It is not possible to adjust the shutter speed to a value slower than the limit imposed by the frame rate used for variable frame rate recording/super slow recording.

The recording is paused when ten hours has past from the time the recording was started. The recording is automatically resumed after few seconds.

– When performing high-speed (slow motion) shooting, the recording time will be shorter than 10 hours depending on the ratio of the frame rate of the recording format and the variable frame rate. The recording will stop in 5 hours when the frame rate of [REC FORMAT] is set to 23.98p and the [SCENE FILE] menu [FRAME RATE] is set to [48fps].

It may take time to stop recording even if recording is stopped right after recording is started.

When set to a 59.94p recording format and [SCENE FILE] menu [FRAME RATE] is set to [2fps], recording continues for up to 30 seconds so that the clip length after recording reaches 1 second.

There are recording functions that cannot be used simultaneously. ( character_reference Recording function that cannot be used simultaneously)

(Variable frame rate recording)

Audio cannot be recorded with the variable frame rate recording. Audio can be recorded, however, if the set frame rate is the same frame rate as [REC FORMAT].

When [SUPER SLOW] is [ON], variable frame rate recording cannot be set.

The screen may be disrupted or become dark when the frame rate setting is changed.

The frame rate cannot be changed while recording.

When recording at a low frame rate setting, it may be difficult for the camera to keep up with changes in the images. If this occurs, use the manual settings for the iris, focus, and white balance mode.

(Super slow recording)

Audio cannot be recorded with the super slow recording.

When [SUPER SLOW] is [ON], the unit will restart after the following operation.

– If changed to an item that does not support [FILE FORMAT] or [REC FORMAT]
