AviSynth MSU Field Shift Fixer

Free AviSynth filter for fixing situation when different lines of source Frame are placed in different output frames. This often occures during Movie Capture, when odd lines are one frame later than even lines. In films after PAL->NTSC conversion there is another problem: in two neighbour frames odd lines are equal and even are different. The main idea of this filter is searching for the optimal line`s position for current frame. If this position exists, optimal odd lines are placed into current frame, otherwise (for example when odd lines are in one frame after even lines and we are in the last frame) the odd field is interpolated, or no changes are done (behavior depends on filter`s settings). After applying MSU FieldShiftFixer to sequence visual video quality is improved, and compression and denoising Processes give better results.
