I already see the wrong-field-order effect as early as 0:55 seconds into the video at http://www.youtube.com/watch?v=nJeowYU0jqo <http://www.youtube.com/watch?v=nJeowYU0jqo> . The effect happens for a split second and then it goes away. It continues this sporadically throughout the video. The .AVI files at http://sciencezero.4hv.org/tslom.htm <http://sciencezero.4hv.org/tslom.htm> are encoded in XviD and sized at 544x352 with a frame rate of 29.97 fps. Since the original source material was shot on film at 24 fps and then telecined to video at either 576 lines at 25 fps or 480 lines at 29.97 fps, either 224 or 128 lines of resolution have been lost. Also, there were some cuts in the film that are now appearing as double images spread over 3 frames. I think trying to fix the bad video is not worth the effort.

About the last third of it the field order is backwards. It starts at the segment where a car body is shown being straightened. There are lower resolution copies on other sites and the series is on YouTube.

Would probably have to convert the first part to an image sequence too and render the whole lot to video to avoid problems joining the original first part and the rebuilt second part. > [Non-text portions of this message have been removed] ------------------------------------ Yahoo!
