The video and audio data (the essence) is identical for MXF and Quicktime files. These
file formats differ in the headers and the method the audio, video and time-code are
multiplexed in the file.
MPG format allows one to record in SD at 5,6,7,8 or 9 Mbps and HD at 19, 25, 35 (4:2:0)
If one records in MPG, one can use various utilities to create two “Elementary Streams”,
one audio and one video. One such free utility is called “MPEG Streamclip”:

Note:
If one provides HD to the nanoFlash via HD-SDI or HDMI, then the MPG files will be
recorded in HD, which is appropriate for a Blu-ray disk. If one provides SD via SD-SDI or
HDMI, then the MPG files will be recorded in SD, which is required if one wants to create
a SD DVD.
51. What is the recommended file format?
MXF is supported on all PC based NLEs and is now compatible with FCP via the Sony
import plugin (see section on NLEs). On the other hand, Quicktime is the default format
for editing on the MAC and we offer a free QT → MXF converter. So, the ultimate file
format choice depends on your specific application (and those of your clients).
52. Can I record different video and/or file formats to the same Compact Flash card?
File format changes are acceptable, but all the files must have the same video format
(1080i60, 720p50, etc) for smooth playback out of the nanoFlash. However, if you do mix
video formats on the same CF card, these files can be transferred to an NLE for editing.
53. Can the CF cards be formatted on the nanoFlash?
Yes. And for proper operation, you should format the cards in the nanoFlash. Both
CompactFlash cards can be formatted simultaneously, which requires less than 5
seconds for two 32 GB cards.
Caution: be certain to remove all cards with footage before formatting any cards, as the
formatting process clears all cards that are currently inserted in the nanoFlash.
54. Can I copy files back onto a Compact Flash card for playback out of the nanoFlash?
Yes, you need to first format the Compact Flash card on the nanoFlash and then copy the
files into the clip folder.
55. Can the Nexto device be used for temporary storage of the recorded clips?
Yes, our testing has shown that the Nexto DI eXtreme ND2700 device is an excellent
device for the temporary storage of your clips. The 500 GB Nexto is great for off-loading
your footage onto another medium, especially when a laptop or other computer is not
present. (http://www.nextodi.com/en/product/eXtreme_en.html)
