automatically start and stop recording when the record-button is pressed on the camera.
Note: your camera must be set to record-run time-code for this mode.
77. Can the nanoFlash be set up for time-lapse (interval) recording?
Yes, time-lapse is accomplished by recording the desired frames using I-Frame Only
mode. The user can select the interval by selecting HH:MM:SS value in the menu. Since
the effective data-rate to the CF card is reduced by 30X (or more), we recommend that all
time-lapse recording be done at 280Mbps I-Frame Only mode, for maximum quality. Note
that smooth playback out of the nanoFlash may be inhibited with slow CF cards. However,
the video file can be transferred to an NLE for editing and playback. (Also note that Sony
Vegas does not support I-Frame only recoding and should not be used with Interval
recording).
78. Does nanoFlash have a pre-record (Cache) buffer?
Yes, the pre-record buffer depends on the chosen bit-rate, as follows:
a. 7 seconds for 100 Mbps (and lower) data-rate
b. 4 seconds for 140/180 Mbps data-rate
c. Pre-Record Cache is not available for 220 Mbps (or higher) recording
79. Can I loop record (overwriting the oldest footage)?
Yes, after recording to both CF cards the nanoFlash will automatically format the first card
and continue recording. So, you will always have at least the last CF card’s worth of video
available when you stop recording.
80. Can I over/under crank (variable frame rate) during recording?
Yes, the nanoFlash records in I-Frame only with muted audio when operating in
over/under crank mode. Please set your camera to output 720p60/50 or 1080p30. Then
set the time base (24, 25 or 30) and the crank rate (1 to maximum incoming frame rate).
81. How do I know the nanoFlash is actually recording?
There are a number of record indicators, including:
• The LED next to the currently active CF card will flash red
• Record start/stop audio tones can be enabled in the HP output
• Red record overlay bar can be enabled on the output monitor
• The tally light will blink (option cable from the 10-pin remote)
82. What are the record trigger (start / stop) options?
Record start / stop can be triggered by one of 5 selectable events:
1. None (nanoFlash setup for playback only)
2. Incrementing time-code (Typically requires Record-Run timecode)
3. Record Start/Stop button on the nanoFlash box
4. External Remote Control switch
5. Auto Record on Power-Up
