Hi Colin,
Wow, that Elmo did you well I think! The sound is suprisingly good for an on camera type on Super 8, most were pretty rubbish and were drowned out by camera noise. You obviously didn't worry about the shot time like I tend to on 50ft carts, with you nice long shots. Sadly I came to cine just too late to be able to buy sound film. I would really be interested to see a comparison between the reduced definition and the HD capture. Might you be able to do a short clip of it perhaps? I hope you get some commercial interest in those for some historic stuff too, it would make a nice Blueray. So much enthusiast stuff is hung up on locos and cab numbers that your footage make such a refreshing change, I know I keep saying it! It's so frustrating to watch those when you really want to see (and hear if there's sound) the whole formation run through the shot!
TTFN,
Ben
