don't have the pedestal below -5 or so...I'd keep it around 0 myself...and use cine gamma. Itll keep the highest amount of detail in your image, and you'll want all the detail you can get on the big screen.
Get a list of settings from the film lab where you expect to do the transfer. DVFILM.COM has a list of recommended settings on their site, but their preferences are optimized for their transfer process... other transfer houses may have different preferences.
pedestal around 0, ok. but swisseffects.ch says, don't use cine gamme - it's most useful if you want a film-look on projects that have VIDEO-TAPE as final output. they recommend "normal" or "high" for film transfer. maybe it's better to have the highest tonal range on the source (as with "normal") and the film-like gamma is created during the conversion to film?
checked dvfilm.com. they have a section about the dvx100, but couldn't find recommondations for image-settings. or am i missing something?
I'd be cautious about using Swiss Effects. They have gone on record as saying they prefer that you use an interlaced VX2000 instead of a 24P or 25P DVX. To me that's just wacky -- but if what they're saying "between the lines" is that their process works better from a VX2000 than a DVX, then I sure wouldn't send them DVX footage -- I'd send DVX footage to a lab that specializes in it (or at least claims to get good results from it).
The only lab I've used are DVFILM and Film Craft Labs (division of Grace & Wild). I only used Film Craft for a 16mm transfer from the VX1000 about 7 years ago, so I don't think my experience with them is relevant anymore.
I don't know of anyone who claims to specialize in the dvx100 other than DVFILM, and they don't specifically claim to "specialize" in it, but they've been at the forefront of developing 24P transfer technology. I've heard good things about the Digital Film Group (I think that's what they're called) up in Canada as well, but have no experience with 'em.
