De-Interlacing for Field Level Examination

dTective allows an analyst to examine video on both the frame and field levels. One second of video is comprised of 30 frames. Each frame contains two interlaced fields. A single second of field-based, multiplexed video contains 60 unique images, far too many for the human eye to comprehend when played back in a standard VCR. Many multiplexed devices record a single camera image on each field of video, but most playback machines only display the odd field hiding all of the video evidence contained in the even field.

Avid quickly and easily separates each individual frame of video into two unique images, allowing the investigator to examine the evidence at the field level. Field-based examination frequently reveals images normally lost to the investigator.
