Recut
How to change a video's aspect ratio (16:9, 9:16, 1:1, 4:5)
Attach the video and say the shape you want, for example "make it square" or "make it 9:16". Recut either crops the picture to fill the new frame or keeps all of it and adds bars, and it never enlarges the picture unless you give it a width.

Make this video square. Keep everything in shot and use white bars.
Step by step
- Attach the videoAdd the clip to a Recut project.
- Say the shapeRecut understands 16:9 (widescreen), 9:16 (vertical), 1:1 (square) and 4:5 (portrait feed), and phrases like "make it vertical", "make it landscape" or "crop to 4:5".
- Say crop or barsCropping fills the frame and cuts off what doesn't fit. Keeping the whole picture adds bars, black or white. You can also give a width in pixels, such as 1080.
- Run itThe resize runs on your device at no model cost, and the result appears next to the original so you can compare them.
What Recut does
Without a width, Recut never makes the picture bigger than it was. Cropping cuts the largest piece of the new shape out of the source: a 1280×720 video cropped to 9:16 becomes 405×720. Keeping the whole picture builds the smallest frame of the new shape around it.
Give a width and Recut scales to it, for example 1080 for a 1080×1920 vertical video. Sizes are rounded to even numbers, which video encoders need.
Tips
- If the video is going to one particular app, ask for an export for that app instead: it sets the size, frame rate and loudness in one step.
- Images can be resized the same way, and they can also have transparent bars.
What it doesn't do
- The crop is centred. Recut doesn't follow a moving subject.
- Recut doesn't fill the new space with invented picture (outpainting) in this step; that needs a generative video model.
