Variable Frame Rate (Vfr) Recording Function; Variable Frame Rate (Vfr) - Panasonic AU-EVA1 Operating Instructions Manual

Variable frame rate (VFR) recording function

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

Variable frame rate (VFR)

Allows the high-speed shooting from 1fps to maximum of 240fps.
1
From the [SYSTEM SETTINGS] menu → [SYSTEM MODE] → [SENSOR MODE], select the resolution and codec of the recording
video, and the frequency that will become the reference frame rate.
f For the combination that can be set, refer to "Selecting the resolution, codec, and frame rate for recording video".
f The range of the frame rate that can perform high-speed shooting differs depending on the [SENSOR MODE] setting.
f When the [SYSTEM SETTINGS] menu → [SYSTEM MODE] → [SDI RAW] is set to anything other than [OFF], the range of frame rate that can
perform high-speed shooting changes depending on the [SDI RAW] setting.
For the combination that can be set, refer to "Selecting the resolution and frame rate of the RAW output".
2
Select the [CAMERA SETTINGS] menu → [FPS] → [VFR SW] → [ON].
f This can also be set with the multidial. Refer to "Functions assigned to USER buttons".
3
From the [CAMERA SETTINGS] menu → [FPS] → [VALUE], set the frame rate in accordance with the shooting condition.
f This can also be set with the multidial. Refer to "Functions assigned to USER buttons".
f An arbitrary frame rate can be added/changed/deleted in the [CAMERA SETTINGS] menu → [FPS] → [ADD]/[EDIT]/[DELETE].
4
Press the REC button.
Variable frame rate recording is started.
r Normal shooting mode
The 4K/UHD video is generated using all the pixels in the image sensor.
2K/FHD video is also generated from that video.
The high-speed shooting up to 60fps is possible.
Select [S35 5.7K] for [SENSOR MODE].
r Pixel mixing shooting mode
The 2.8K pixel mixing read is performed from all the pixels of the image sensor, and generates the 2K/FHD video.
The high-speed shooting up to 120fps is possible.
Select [S35 MIX 2.8K] for [SENSOR MODE].
f The angle of view is the same as the normal shooting mode.
r Cut-out shooting mode
Cuts out the image circle of Four Thirds from the center of the image sensor, and performs the pixel mixing read of 2.2K. 2K/FHD video is also
generated from that video.
The high-speed shooting up to 240fps is possible.
Select [4/3 CROP&MIX 2.2K] for [SENSOR MODE].
f The angle of view will change from the normal shooting mode.
@ NOTE
t Recording of audio is not possible with the variable frame rate shooting. However, audio is recorded when the frame rate is set to same as the system
frequency.
t The screen may be disrupted or become dark when the frame rate setting is changed.
t The frame rate cannot be changed while recording.
t The [REC SETTINGS] menu → [TC] → [FREE/REC RUN] is fixed to [REC RUN].
t 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 a high-speed 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 [FREQUENCY] is set to [24.00p], and [FPS] is set to [48fps].
t For recording limitation during the variable frame rate shooting, refer to "Recording function that cannot be used simultaneously".
t It may take time to stop recording even if recording is stopped right after recording is started.
When [FREQUENCY] is set to [59.94p] and [FPS] is set to [1fps], recording is continued for maximum of one minute until the length of the clip after
shooting becomes one second.
