Here are some of the most Frequently asked questions we recieve, if you cannot find your answer here please feel free to send us your question by email to [email protected]
How much is the QTAKE HD software?
How do I install QTAKE HD?
How do I register my Dongle?
Q: How Much Delay is there in QTAKE?
A: 2.5 frames. 2 frames through the Various AJA products for video input to the computer. .5 frames delay thru the triple head to go to the Gefen dual SDI scaler.
Q: Will there be more delay if I chose to output from the Kona card instead of the GPU?
A: Yes. about 5-6 frames of delay if you use SDI out for processed live output.
Q: Do I have to use the DVI out to output from QTAKE?
A: No. You can use the Video cards output .
Q: Is a Macbook fast enough to run 2 cameras in QTAKE?
A: YES
There is slightly more delay using BMD hardware and they do not support SDI flag support for several cameras.
Qtake ingests video using the capture cards and can output using the capture card if you have 2 of the capture boards.
While some customers choose to do this. the problem with this approach is the added latency.
GPU out in Qtake works by creating a secondary dispay in Qtake
HDX1 1920 x 1080
HDX2 3840 x 1080
HDX4 3840 x 2160
Input latency = 2 frames using AJA and more using BMD. Assuming using 1080p23.967
Matrox Triple head to go splits the 3840 x 1080 display into 2 Display ports at 1920 x 1080 each
The Gefen scaler is the best device to convert this signal using DVI to SDI scaling.
Matrox can only be set to the output frequency of the mac. This has been the only viable option and the one used by a majority of Qtake owners up till now.
Output using the GPU out via Matrox triple head to go and Gefen scaler combo = .5 frame 1080i60 (or 59.94)
On close inspection Video has some smoothness issues because of the added frames.
QOD is a direct conversion from Display Port to 4 SDI ports
Outuput Using QOD in 1080i60 = 1 frame
Outuput Using QOD in using frequency 1080p23.976 = 2 frames
QOD output is perfectly smooth to match input from the camera.
