What speed specification of CF card is required for DV-66 to play MPEG-2 video clips smoothly?
We recommend a minimum of 40X (Ultra high speed) or above for MPEG applications. ADDITIONAL NOTES: First, the MPEG-2 specification bit rate is between 3Mbps–8Mbps. (If you play the MPEG file in the power DVD or other software, you can open some OSD function to show this rate on the screen). For the DV-66, it is refer to the READ rate of the CF card: 1X speed = 150kbps For example: Normal speed 24X CF card = 24X * 150K = approx 3.60MB/s. High-speed 40X CF card = 40X * 150K = approx 6.00MB/s. Following the above formula, you may calculate the suitable Compact Flash card speed for your application. For a normal resolution video footage, the average bit rate might be just about 3Mbps to 4Mbps and the peak bit rate might be just 5Mbps or 6Mbps. Then, a 40X Compact Flash card will be adequate. For a higher resolution video footage with numerous frame changes, the average bit rate 5Mbps to 6Mbps and the peak bit rate 8Mbps-9Mbps. A Compact Flash card of 50X ~ 60X is needed to play the video
