iOS 11: HEVC, HEIF, new video and photo formats are becoming more and more popular among iOS users.
The option is located in the camera menu with the title "High Efficiency". The nature of the title isn't self explanatory, however it is something users may select with out knowing what it does.

We have also received a few requests asking when will this feature be available. Is there plans to integrate this in Prontoforms sometime soon?
