Hi Matt
I’ve never seen a Malincam or similar video device in operation, so I cannot compare the two. With the DMK cameras, using IC Capture, you can see the real time video stream just like watching a DVD or movie on TV whilst the data is being written to the HDD, with the proviso that the PC has enough grunt!
The DMK21 at 640x480 can run at 60fps on my 6 year old IBM ThinkPad R40 which has a Centrino 1.4Ghz processor, 512MB memory and an 80GB HDD, although I record to an external USB2 320GB HDD.
The on-screen images from the DMK31 at 1024x768 stutter along, only showing every n’th frame. I suspect this is caused by the limited resources on my aging ThinkPad. However, it does record the full video stream without any problems; it’s just that the display stutters under the load. The DMK31 is just fabulous for its larger chip size although its maximum frame rate is 30fps compared to the 60fps for the DMK21.
The DMK series are B&W and you need an IR blocking filter to reject the IR end of the spectrum.
The DBK series are colour and they too require an IR blocking filter.
The DFK series are colour but they are fitted with a built in IR blocking filter and these are not recommended as the filter isn’t optimal for astrophotography.
With the DMK’s you record the data and then process the AVI’s through Registax which is at release 5 now – a fantastic Aligning, Grading, Stacking and Finishing application that is the de facto standard for web cam imagers.
Hope that helps!
Cheers
Dennis
