Yes, this is clearly possible. In fact the analog signal doesn't carry information about the field order (if any). The video editing/encoding software does motion estimation for this, and there is no other way (given that the video material can change from progressive to interlaced and vice versa, and probably can change the field order, at any time). -- Krzysztof Halasa Industrial Research Institute for Automation and Measurements PIAP Al.
