Dorr exports photo videos in portrait 9:16, square 1:1 and landscape 16:9. Choose a ratio based on your photos and where you expect people to watch. Preview the same images in each shape and check that the important subjects stay in frame.

Shape and resolution are different decisions

An aspect ratio describes the relationship between a frame’s width and height. A 9:16 frame is taller than it is wide. A 16:9 frame is wider than it is tall. A 1:1 frame is square.

Resolution describes the number of pixels in the exported video. Changing a video from portrait to landscape does not unlock HD quality. In Dorr, standard-quality export is free with possible ads; HD export is part of Dorr Pro.

Compare the three formats

| Format | A useful starting point | What to check | | --- | --- | --- | | 9:16 portrait | Vertical photos and upright phone viewing | Wide group photos, faces near the edges, long text | | 1:1 square | A balanced composition for a mixed photo set | Details at both the top and the sides of the original | | 16:9 landscape | Broad scenery and horizontal compositions | Tall portraits and small subjects in a wide frame |

These are creative starting points rather than universal requirements for a particular social platform. Choose the shape that serves the pictures and the way you want the video to be viewed.

Make a fair comparison

Keep your photo selection, order and theme the same while switching the ratio. If you change everything at once, it becomes difficult to tell whether the frame or the theme improved the result.

A landscape with a small person on one edge is a useful test image. Try all three ratios and look at the person, the horizon and any detail you would be sorry to lose. Then check a portrait from the same sequence.

Dorr’s preview is the place to judge the final composition. A simple crop illustration on a website cannot reproduce how every Dorr theme places and moves photos.

Check these details before export

  • Faces close to an edge, especially in group photos.
  • Text you added to a photo, including dates and titles.
  • Tall buildings, narrow paths and very wide landscapes.
  • Small subjects that may be difficult to see on a phone.
  • The first and last frames, which should still feel intentional.

If a picture does not work in your chosen format, try editing it individually, choosing a different image or comparing another theme. You do not need to keep a photo simply because it was in your original selection.

For a travel sequence, decide which frame best preserves the landscapes and people you care about. The travel slideshow guide helps with the photo order; the photo-to-video overview explains how themes, music and duration fit together.
