LTX 2.3 Reframe: change video aspect ratio automatically

LTX 2.3 Reframe is an automatic reframing model from the LTX 2.3 video family. Instead of generating a clip from a prompt, it takes a finished video and reshapes it into a different aspect ratio: the original footage is re-cropped to the target frame and the freshly exposed edges are generated to blend with the scene. It runs without any text prompt and outputs at up to 1080p, so repurposing one shot for several platforms takes a single pass.

Reframe converts a video into any of five aspect ratios — 16:9, 9:16, 1:1, 4:5, and 5:4 — with 16:9 as the default. Choose 720p or 1080p output (1080p by default) and the model handles the rest: it re-crops the shot, then paints in the newly revealed edges so nothing looks stretched or letterboxed. Because it takes only the video plus your ratio and resolution settings, there is nothing to prompt and no timeline to edit. It sits alongside LTX 2.3 Audio to Video and LTX 2.3 Outpaint in the LTX 2.3 family, while LTX 2.5 Pro and LTX 2.5 Fast handle text-to-video generation.

Picsart runs LTX 2.3 Reframe inside its AI Playground, so you upload a video, pick a target aspect ratio and resolution, and get a reframed clip back with no model setup. Everything happens in the Playground: choose the ratio you need, let the model re-crop the shot and regenerate the edges, and download the result ready for its destination.

Creators reach for LTX 2.3 Reframe when they need to change a video's aspect ratio fast and keep it looking intentional. There is no prompt to write and no manual crop to fine-tune — pick a ratio and the model regenerates the edges so the subject stays centered and the frame stays full. It is the quickest way to make one shot work as a video aspect ratio changer across widescreen, square, and vertical feeds.
