A better first pass

Move from a folder
to a confident shortlist.

Review large RAW folders without an import step, group rapid sequences into compact stacks and keep the strongest frame close at hand.

MPViewer 1.4 grouping burst photographs and building a local Best Shot shortlist — **From burst to best shot**Stack rapid sequences, scrub every frame and promote the keeper.

Private, on-device assistance.

Optional Best Shot and Blink Analysis help identify stronger frames without uploading photographs or creating an account.

Cull with either hand.

Use WASD on the left or J/K/O/P on the right. Ratings, picks, rejects, color labels, auto-advance and visible feedback keep the review moving.

360° photos and video

Then reshape it.

Under the hood

Faster where
waiting hurts.

MPViewer 1.4 improves RAW and 360° rendering, fullscreen-to-gallery transitions, burst navigation, keyboard focus, sandboxed folder access and sidecar integrity.

Large previews stay sharp while zoom levels change, completed renders are reused, and 360° adjustments no longer block the interface. The result is a smoother workflow on both Apple silicon and Intel Macs.
