Important

• You can extract a video from only one video window at a

time.

• Do not specify the Windows folder or the Program Files folder

on the system drive as the destination. Video cannot be

saved to these folders.

• You cannot save only audio data.

• When extracting a time range that contains different video

formats (such as JPEG and H.264), divide the range by

format and save each video segment individually.

• When the data size of video being extracted reaches 2 GB,

extraction will stop and the video extracted to that point will

be saved, even if the specified end time has not been

reached.

Play back the .mov file to check if the specified length of

video was saved.

When data size is expected to exceed 2 GB, divide the

extraction time range. Refer to “Data Size and Bit Rate

Estimates” (p. 26), and calculate the estimated data size.

– Calculating time in minutes to 2 GB (JPEG)

2,097,152 KB/(data size per frame (KB) x recording frame

rate (fps) x 60 sec.)

– Calculating time in minutes to 2 GB (H.264/MPEG-4)

2,097,152 KB x 8/(bit rate (Mbps) x 1024 x 60 sec.)

Specify the video extraction time range so it is within the

calculated time estimation.

• Block noise may appear when a video recorded in H.264 and

saved in .mov format is paused during playback using

QuickTime.

• Initially, noise may be present when playing back extracted

video recordings that include audio.
