LTX 2.3 Pro remains executable for previous-generation production jobs, saved briefs and existing examples. It still exposes text, image, audio, Extend and Retake workflows, while LTX 2.5 Pro is the current successor for new production planning.

Reframe a source clip

Reframe on standard LTX 2.3 keeps exact source timing for clips up to 60 seconds, at 720p or 1080p, with a target aspect ratio and no prompt. This does not add Reframe to LTX 2.3 Fast or LTX 2.5.
