FAQ

How do I convert landscape video to portrait?

Upload your landscape video, choose a portrait aspect ratio such as 9:16, then let AI reframe the shot. The AI will adjust the frame around the main subject instead of simply cropping the center.

Can I convert a landscape video to portrait without black bars?

Yes. AI Reframe can fill the portrait frame by repositioning and scaling the video around the main subject. This helps avoid black bars while keeping the important part of the video visible.

What is the difference between an AI landscape video to portrait converter and a regular crop tool?

A regular crop tool cuts a fixed area of the video. AI Reframe analyzes the scene, detects the subject, and adjusts the frame over time. This is especially useful when the person, product, or action moves across the shot.

How long does it take to convert a landscape video to portrait?

5s clips usually take 4 minutes. Larger or higher-resolution videos may take longer. It depends on the video length, file size, resolution, and server load.

Do I need to reshoot for Shorts or Reels?

No. You can reuse existing landscape footage and convert it into portrait formats for Shorts, Reels, and TikTok. For the best result, use footage where the subject is clear and not too close to the edge.

Can AI extend the video frame?

Yes, if the tool supports AI video outpainting or background extension. AI Reframe changes the crop and framing, while AI frame extension generates missing background areas. Reframe is faster; frame extension is better when you want to keep more of the original scene.

Can I convert portrait video to landscape on Lanta AI?

Yes. Lanta AI can convert portrait videos into landscape formats such as 16:9 or 4:3. It uses the same AI subject tracking to keep the main subject in frame, and can extend the video background with AI so the final landscape version looks natural.

Can I download without a watermark?

Yes. Free users can download videos with a watermark. Paid users can export and download videos without a watermark.

Can it batch convert videos on Lanta AI?

Yes. Batch conversion is available for paid users. You can convert up to 10 videos at the same time, which is useful for creators and editors.

Can it output 3:4, 4:3, and 4:5?
