StereoMate

Separate images are paired by name (…-l / …-r, _L / _R, left / right); otherwise in sorted order. Use ⇄ in the list to swap a single image.

Manual: starts as the automatic, centred crop; tick “Edit crop on the image” to move it (drag inside) or resize it (drag an edge or corner). Auto – inside with a fixed aspect ratio can be slid in the direction where it has room.

Black stripes on the left edge of the left view and the right edge of the right view bring the image edges in front of the screen (no window violation). Auto uses the objects with negative parallax near the left and right edges.

Values are corrections of the right view relative to the left one (full-resolution pixels); “Rotate both” turns the whole pair. Apply current values to all images copies them to every other image (time-lapse, fixed stereo rig). Click a field, then use the mouse wheel (Shift = larger steps).

No correction.

The matching compares only the part both views show (inside the crop). Manual values act on both views equally, so the views stay matched. Click a field, then use the mouse wheel (Shift = larger steps).

Put one or several aligned images, smaller, into one new stereo image with background, gaps and frames — this reduces the depth of too deep images (depth in % refers to the final width). The program suggests layouts that keep the depth limit.

The final slide show with music from finished (saved) stereo images — with subtle zoom, panning and depth motion, text slides, transitions and a 3D tag. The show has its own list. Video clips and time-lapses are made in Export.

Set automatically when the format changes: 4:2:0 for side-by-side, over-under, MPO and L/R; 4:4:4 for anaglyph and interlaced.

Shows the current image (aligned, cropped, corrected) without anything else and follows every change. In the window: double-click = full screen, S = swap views, Esc = leave full screen. Interleaved formats need full screen and 100 % display scaling.
