Three control is pretty intuitive and responsive, better than most of those frame-grabbing apps I've tried. Yet this app does not support exporting HDR photos even if the video is HDR, which is a huge miss compared to them. Also hopefully the developer could consider supporting Live Photo and GIF export in the future, make the app a true all-rounder which many similar apps already do.

Response from developer
Thanks for the thoughtful feedback and suggestions! HDR photo export is now supported — HDR video frames can now be exported as true HDR HEIF/HEIC images. Live Photo and GIF frame extraction are also now supported, along with batch extraction options, improved extraction controls, and enhanced media detection and status display.
