6. Special care must be taken when using conversion filters with the DVR Express It is generally recommended that the Acquire Only 8 bits per Pixel setting always be left unchecked when using conversion filters with cameras having bit depths greater than 8 bits Most conversion filters are designed to process full bit depth pixels If this setting is enabled only 8 bits are available which can cause a conversion filter to incorrectly process the image When using any of the available Bayer conversion filters and the live image is reduced in size please note that the image may appear as a monochrome image even if the Display colour images setting is checked This is due to the fact that the reduction in image size may remove pixels required to re construct the full colour RGB image from the Bayer pattern image DVR Express Section 3 49 3 4 9 Video File Benchmarking The video file benchmarking tool provides a convenient way to measure the write performance of the disk array where the video file is located Please note that the video file is erased during the benchmarking operation The video file benchmark erase window is shown below Yideo File Benchmark Erase x Write block size in kilobytes fi 024 4 Benchmarking erasing video file Press Cancel to halt ARNING Current video file is being erased 100 complete Estimated time remaining 0 min 0 sec Current Pass GB 5 Write Speed 118 0 MB s Average Write S
