Frequently Asked Questions
Can I use SATA Drives for RAID storage with the KONA product line?
AJA always recommends the use of SCSI or Fibre Channel storage solutions for use with
KONA products.
I updated the KONA software and my KONA hardware is now missing,
Why?
A function of the uninstaller is removing the current driver for the KONA card. In doing this
the KONA hardware is removed completely. A “plug and play” request must be made to
install a new driver for the hardware. This can be done be either restarting the system or
going into device manager and searching for new hardware. On startup the computer
automatically looks for new or uninstalled hardware.
Can the KONA handle HDV , P2, XDCam, or AVCHD? If so how?
HDV, XDCam, P2, and AVCHD files will play real-time in Premiere Pro when using AJA
supplied project presets. Alternatively, you can use KONA to capture uncompressed from
these cameras if they have SDI, HDMI, or Analog outputs.
Does KONA Offer Support for compressed codecs?
All KONA cards can capture DV 25 and DV 50 compressed QuickTime files from analog and
digital sources through their available inputs. KONA LHi and KONA 3 can also capture
DVCProHD compressed QuickTime files for HD resolutions. Please see our DVCProHD white
papers (see the whitepaper DVCProHD Editing with KONA and KONA at
http://www.aja.com/pdf/AJA_whitepaper_DVCProHD_editing.pdf ).
I am using After Effects for compositing and sometimes my preview is
not in real time—why is this?
RAM Preview should be very close to real-time for HD in After Effects 7. Please ensure you
have the following settings for proper RT RAM preview.
1. Make sure that the “Primary Format” of the AJA Preview Panel in AE7 matches the
resolution and frame rate of your After Effects Composition.
2. Also, RT RAM Preview is only possible with 8-bit AE Projects and with the “8-bit RGBA
4:4:4:4” setting for the “Output 8-bit As:” found in the AJA Preview Panel Color
Options. Other color spaces and AE Project depths require a software transformation
of the video data before being displayed—thus slowing down preview.
3. Next, please ensure that the “Resolution” setting for “Time Controls” is set to “Full”. If
not set to “Full”,the image that the AJA Preview Panel receives and sends to the
KONA board during RAM Preview will not be sent at “Full Resolution” and thus will
either be software resized to Full Resolution before sending to the KONA Board for
display, or will be center cropped before sending. The latter choice is controlled by
the checkbox in the AJA Preview Panel labeled “Auto Resize Image” under the
“Primary Format” Setting.
4. If RAM Preview is still not real-time, you can try some of the following – setting your
Zoom to “100%” in your AE Composition, making sure the “Frame Rate” of the AE
Time Controls” matches the frame rate of the “Primary Format” in the AJA Preview
Panel, and muting audio in the AE Time Controls.
