Text Cut Off in Reels or Shorts? Find Where It Happens

When a title loses its last letters or a subtitle disappears under buttons, the first question is where the loss happens. Text may already be clipped in the exported video, cropped by a particular display, or merely covered by the app interface. Each needs a different fix.

Keep your editing project and the last clean export. The Motionix safe-zone checker can help inspect placement with editable margins and manually defined boxes. It cannot restore clipped pixels, move baked-in text, or certify a Reel or Short as safe for every viewer.

Check the exported file first

Open the actual exported video in a local player, outside the social app. Examine the affected moment at a useful size. If letters are missing there too, return to the editor before changing any platform settings.

Check the text box width, line breaks, alignment, and any masks or crop effects. Inspect the entire animation: a title may briefly travel outside the canvas even if its resting position looks correct. If the editor preview is fine but the export is not, compare export dimensions and aspect ratio with the project.

Move or resize the editable text layer and export a new copy. A checker overlay cannot repair text that has already been cut out of the image. Do not solve the problem by shrinking essential captions until they become unreadable.

Compare the destination views

If the local file is intact, compare the app's upload preview with the specific view where the problem occurs. A feed preview, profile preview, and full-screen player should not be assumed to show identical framing or interface elements.

Determine whether the image itself is cropped or whether text remains underneath a caption, button, or account label. The same file may need a separate cover composition rather than a single arrangement that attempts to serve every preview.

Also distinguish subtitles from the post's description. Burned-in subtitles are pixels in the video. App-generated captions and the post description are separate interface layers that may compete for the same space. Check whether two caption systems are being displayed simultaneously before adding more text.

Review placement with deliberate boxes

1. Load a representative frame or supported video into the checker.
2. Adjust the advisory margins to the viewing context you are reviewing.
3. Define a box that includes the full title or caption, including outlines, shadows, and wrapped lines.
4. Inspect edge overlaps and reposition the real element in your editor.
5. Repeat for the longest text and animated positions, then upload a fresh preview for another check.

A box inside the chosen area means only that it clears your current geometric margins. It does not mean the app has approved it or that the tool has read the words. For the underlying distinction, see video safe zones explained.

Test captions and real devices

Try the actual caption or description length, not a short placeholder. Where practical, check more than one screen size and review both collapsed and expanded interface states. Verify contrast and reading time as well as position; fully visible text can still be hard to read.

For burned-in subtitles that appear at the wrong time rather than the wrong place, correct the timing in the source project. For a separate subtitle file, use the subtitle timing guide. Moving a text box does not fix synchronization.

Sources and review limits

Reviewed November 6, 2026. TikTok's in-feed ad guidance ties safe zones to dimensions, caption length, and additional formats. Google's YouTube ad guidance describes changing overlay positions. Both are ad references, not proof of fixed margins for organic Reels or Shorts. Meta's official Reels guide was unavailable during review, so no Instagram-specific numeric rule is claimed. Final checking remains placement- and device-dependent.
