Hi again,
Well, I got all the 9.5mm scanned, and am very happy with the results. Images4Life were awesome. Their advice was that good quality 9.5mm film does deserve a higher-than-HD res. scan, so I got it at 2336 x 1752, the max resolution of their Flashscan Choice.
They don't charge anything for the extra resolution beyond 1080p, which is very friendly. To be (excessively) thorough, I asked for ProRes 444(4) instead of the standard 422, which was charged a little extra.
Not all the source footage warrants the 2.3k scan, but it's from 1936! When it is all in good condition the detail is impressive.
I'll be getting a whole lot of 8mm and Super-8 scanned through Images4Life.
Stephen
