Why a vertical clip gets black bars in a wide project

You add a vertical phone video to a wide project, and black bars appear on the left and right. That usually does not mean the clip is damaged. The clip and the project have different shapes, and the editor is showing the whole clip without stretching it.

You can keep the full frame, crop the clip to fill the wide canvas, or change the project to portrait. First check whether the bars are added by the editor or are already part of the video.

Check the clip and project

1. Look at the project or sequence aspect ratio in your editor's settings. A common wide format is 16:9, such as 1920 by 1080 pixels. A common vertical format is 9:16, such as 1080 by 1920 pixels.
2. Click the clip in the timeline and look at the preview. Check whether the black bars sit beside the picture or are part of the clip itself.
3. Choose a frame with clear detail near the top and bottom of the video. This helps you judge whether a fill or crop setting would cut off anything important.
4. Move the playhead to a few different points. If the bars stay in the same place inside the picture, they may be baked into the source file rather than added by the project.

Do not stretch the clip wider just to cover the bars. Stretching changes the shape of people and objects. It can make a face look broad, for example, without adding any missing picture.

Choose how to handle the bars

Keep the full vertical frame

Use a fit or contain option if you want viewers to see the entire original clip. The video will remain tall and the wide canvas will show empty space at the sides. Depending on the editor, that space may appear black, transparent, or as the project's background color.

This is the safest choice when the whole scene matters, such as a person demonstrating a movement or a phone screen recording. The bars are a tradeoff for keeping every part of the image.

Fill the wide canvas

A fill or crop-to-fill option enlarges the vertical clip until it covers the wide canvas. For a 9:16 clip in a 16:9 project, much of the picture above and below the center will be outside the frame. Check the preview carefully and reposition the clip if your subject is too high or too low.

Filling works when the important action stays in the middle of the frame. It can be a poor choice for a full-body shot, a tall building, or anything with important detail near the top or bottom.

Make the project vertical

If the finished video is for a vertical feed or phone screen, set the project canvas to 9:16 before you edit further. The editor may call this the project size, sequence settings, canvas, or aspect ratio. Select a portrait preset or enter dimensions such as 1080 by 1920.

Changing the canvas can affect other clips, titles, and graphics in the project. Review the whole timeline afterward. A title positioned for a wide frame may sit outside the visible area of a portrait frame.

Use a background instead of cropping

Some editors let you place a blurred, enlarged copy of the same clip behind the original. The full vertical image stays visible in front, while the background fills the wide space. You can also use a solid color or a still image as the background.

This avoids cutting off the source picture, but the result looks different from a simple full-frame clip. Keep the background subtle so it does not compete with the subject.

Remove the bars without distorting the picture

1. Set the right project shape. If the final video should be vertical, change the project's aspect ratio to 9:16. If it should be wide, leave the canvas at 16:9 and decide how to treat the vertical footage.
2. Try fit or fill on the clip. Select the clip and look for a framing or scaling choice. Use fit to preserve the full frame, or fill to crop the top and bottom. Names vary between editors, so check the preview instead of relying on a particular label.
3. Reposition the crop. If fill cuts off the subject, adjust the clip's position in the preview or its transform controls. Keep faces, captions, and other important details inside the visible frame.
4. Add a background if you need the full image. Put a blurred duplicate, a color, or a still image behind the clip. Make sure the foreground clip remains large enough to see clearly.
5. Export a short test. Export a few seconds using the same aspect ratio as the project, then open the file in a player. This checks the actual result, not just the editor preview.

For a wide export, choose a wide resolution such as 1920 by 1080. For a vertical export, choose a portrait resolution such as 1080 by 1920. The pixel dimensions should match the project shape. Exporting a vertical project as a wide file can add empty space or cause another crop, depending on the editor.

When the bars are part of the original clip

If the black areas appear inside the clip even when you view the source outside the editor, changing the project canvas will not remove them. The video may have been exported with bars, recorded with a wide layout, or placed inside a black background before you received it. Cropping can remove those areas, but it also cuts away some of the picture.

Check the source file's dimensions in your editor or file information. A file with wide dimensions can still contain a narrow portrait image surrounded by black pixels. If you cannot crop without losing important content, ask for the original unedited clip or use a background layout.

Why the preview and exported video can differ

The editor preview shows how the clip fits the project, while the exported file has its own dimensions and aspect ratio. A video player may also add bars when the file shape does not match the player window. Those player bars are not necessarily part of the video itself.

Check the exported file in a second player or resize the player window. If the bars move or change with the window, the player is likely preserving the video's shape. If the bars stay embedded around the picture, they are in the exported image and need to be removed through cropping or by returning to the original clip.
