nanoFlash FAQs

12. Can nanoFlash be upgraded to support 4:4:4?
No, this is outside the capabilities of the hardware design.
13. Will 1080p60/59.94 or 1080p50 be possible in a future release?
Support of these formats requires 3G HD-SDI (or dual-link 1.5GHz HD-SDI), which is not
possible with the current hardware.
14. Can nanoFlash auto-detect the incoming HD/SD-SDI / HDMI stream?
Yes. Select the video input source: HDMI or HD/SD-SDI via menu control and nanoFlash
will automatically sync to the incoming video. The format is displayed in the lower left
corner of the LCD screen: 1080i50, 1080sf23, etc. (Note: No SRC = No Source detected).
15. Can nanoFlash be used as an HD/SD-SDI → HDMI or HDMI → HD/SD-SDI converter?
Yes, this capability is inherent in the design. Both outputs are live, even when the
nanoFlash is not in record mode.
16. Does nanoFlash perform cross / down conversions?
No, nanoFlash does not perform 1080i ↔ 720p or HD ↔ SD type conversions. Our
design goals limited the power and size of the box. Also, cross / down conversion was
deemed unnecessary, as most video sources already provide this functionality.
17. Can nanoFlash remove the pull-down (inverse telecine) and record in 1080p24/
23.98?
Yes, assuming the 1080i59.94 input was created using a 23.98p frame rate, and then the
nanoFlash can remove the extra frames and record at the 23.98p frame rate. Both
2:3:2:3 and 2:3:3:2 cadences are supported with either HD-SDI or HDMI input.
This feature is enabled by selecting the 3:2 Removal in the menu. Note that the video
format “1080pd23.9” will be displayed on the LCD screen.
18. Can nanoFlash also remove the extra frames on 720p24 over 60 formats (VariCam)
and record 720p24?
Yes, additionally, the nanoFlash can remove the extra frames in 720p25 over 50 and
720p30 over 60 formats.
19. Can the nanoFlash perform a 3:2 pulldown and playback 1080p24 over 1080i60?
No, this capability is not planned for the nanoFlash, as most monitors support 24p.
20. Can I use two nanoFlash recorders for 3-D?
Yes, assuming both cameras are genlocked, then both nanoFlash units will be frame-
locked together. We recommend using I-Frame only recording to ensure that each frame
is compressed in an identical fashion. Note: for enhanced 3D recording and playback,
please consider nano3D..
21. I understand that most cameras output 1080psf instead of true 1080p formats, what
is the difference and how is this handled in the nanoFlash?
PSF (Progressive Segmented Frames) was developed for streaming 1080p HD-SDI
