Curious if NeoHD does work well with the canon HF100 and HG10 for removing the 24P pulldown from the files?

If so does it batch files from folders? and to what output file types? and last how large (on average) would an hour or high quality 1920x1080 (HF file) 24P output file be?

Yes it works well. See info on AVCHD support here : http://www.cineform.com/products/TechNotes/AVCHD_FileConversion.htm

The resulting 24P CineForm AVIs will be between 10-16MB/s depending on the quality setting you choose (Medium to Filmscan1). So an hour 36GB-57GBs.
