2. Usage Examples
In many productions, at the end of the day or end of the event, your customer or some of your
partners may want a copy of the production, either for reviewing it or maybe just for safe
keeping. It is not uncommon during events that many people involved such as producers,
referees, players or other people will each want a copy of the data.
To fit all different purposes, the data can be recorded in SD or HD. Although it can take in as
inputs several types of video standards, it can downconvert the HD types into SD quality to fit
more data on smaller USB sticks. But it can also record in HD quality to keep as much of the
information of the data as possible allowing you to use it in professional equipment later on.
2.1 Choose quality
Standard Definition quality recording –3mbps –1hr/1.35GB
No matter the standard you feed into the device (HD or SD), it can be saved into SD (when fed
HD it downconverts it to SD if that option is selected in the menu). The SD quality is at 3mbps
and is very good if the copies are simply meant for reviewing (i.e players from a team during a
game want a copy of the game to review the game on the way home). This makes it possible to
fit a lot of data on small and cheap USB sticks as you will be able to record 1hr of data on 1.35GB
of memory.
High Definition quality recording –8mbps –1hr/4GB
This quality level can be suitable if you intend to save a proper Master copy of the data you feed
into the device. The recorded data is kept in the format it is recorded in. Meaning that i.e
1080i50 will still be interlaced on the usb stick making it easier to later on ingest into professional
equipment for editing and playback. This high quality does however take up more space so make
sure the USB devices you use are big enough.
2.2 Conservation of type
If the input format (such as 576i or 1080i) is interlaced, the files created on your USB devices
during the recording process will also be interlaced. Most programs on computers, MACs and
smart TV automatically deinterlace it during playback. Leaving it interlaced also means it is easier
to reuse later on professional equipment in the same format.
If the input format is progressive (such as 720p50), the files created will also be progressive.
This was designed on purpose to make it easier for all kind of users. Professionals can work with
the data without converting it forth and back and non technical users can easily review the data
as almost all playback devices deinterlace automatically.
