@tonybeccar, about DualISO again...
Is it possible to implement / connect cr2hdr app (which requires making folders, copying app files and dragging and dropping DNGs - all by the hand, with dozens of MLVs is unbearable) with your app to have DualISO movie GUI.
Your app could recognize wheather unpacked DNGs are dual iso or not and give an option to queue and proccess it automatically one by one via cr2hdr . There is such an app - barracuda but as far as i know it process only dual iso cr2 files, not DNGs. Thank you for your great work!
