The opening frame of the Darnell footage is less than 20 seconds after the headshot.
At the time of the opening frame Weigman, is filming the Hesters.
He finishes filming around 17 seconds after the headshot.
Four or five seconds into this footage we see Weigman running down the knoll to where the Newmans are.
Nobody has detailed the route Wiegman took: (1) from the point we see him stumbling/falling on the Bell Film, to, (2) the point we see him standing at the bottom of the Knoll. Point (1) and Point (2) are Not inline. The Wiegman story has always been that he Stopped Filming when he ran Down the knoll. Now, we know that Wiegman was also Not Filming when he moved from point (1) to place him inline with point (2). This expands the Wiegman Tick/Tock. If Wiegman stumbled and then Fell as he moved into position to run down the knoll, this would be additional Tick/Tock.
"Pictures Of The Pain" details that Wiegman saw SA Lem Johns UP the knoll. Is it during the above time frame that Wiegman saw SA Johns? Wiegman claiming to have seen SA Johns UP the knoll, is contrary to Johns claiming that he never left Elm St after jumping out of the LBJ SS Car. For its' initial 30 yrs, the Wiegman Film was ballyhooed as being filmed "continuously". Did Wiegman actually continue filming while he moved between points (1) and (2) and film SA Lem Johns UP the knoll? This possible "lost" footage would also be "lost" Tick/Tock. To this day, NBC has steadfastly refused to release the Original Wiegman film.
