# Luma Modify Video Alternative > Luma Modify Video re-renders existing footage while keeping its motion, with Adhere, Flex and Reimagine strengths; on Luma's current Ray3.2 model it handles up to 20 seconds at 1080p. A Luma Modify Video alternative for targeted changes is Kenerate Genjutsu, which swaps one thing — character, object, outfit or background — from references and a prompt.

Short clips where faces, costumes and edges must stay crisp. - Kenerate Genjutsu (Kenerate): Clip 2–15 s + up to 10 references → 480p, 720p or 1080p · ~2–4 min. Fast targeted edits on clips up to 15 s. - Seedance 2.5 (ByteDance): Clip 4–30 s + up to 30 references → 480p to 4K · ~4–8 min. Longer clips than Modify Video's limits, many references, 4K. ## Steps 1. Upload the clip — MP4, MOV, WebM or M4V up to about 100 MB; 2–15 s on the Kenerate tiers, 4–30 s on Seedance 2.5. 2. Decide what changes — Character → Replace character, prop → Swap object, clothes → Change outfit, place → Change background. 3. Add references instead of a first frame — Images of the new character, object, garment or place, mentioned as @image1, @image2. 4. Write the change — One or two sentences. Everything you don't mention is told to stay. 5. Compare, then restyle if you want — Synced compare view; for a whole new look on top, use the Restyle the result hand-off. ## In depth ### Global strength versus a named target Modify Video's presets answer "how much may this clip change?" — a dial from retexture to reinvention. Genjutsu's modes answer "what may change?" — the character, an object, the clothes or the place — and each mode's instruction lists what must stay: performance, timing, camera, framing and light. Neither is better in general; they suit different briefs. ### References instead of a first frame A reference shows the target; the prompt says where it goes. - Luma: guide with a prompt, visual references or a first-frame image. - Genjutsu: guide with a prompt and numbered reference images. - One reference per thing that changes keeps intent clear. - Several angles of one character hold identity better. - Seedance 2.5 takes up to 30 references in one run. ### Chaining a targeted edit and a restyle Some briefs need both: a new lead and a new look. Run the targeted change first in Genjutsu — Replace character, say — then send the result to Restyle the result for the whole-clip style. Doing it in that order keeps the identity decision separate from the style decision, and each step can be redone without losing the other. ## FAQ Q: What is Luma Modify Video? A: Modify Video is Luma AI's tool for transforming existing footage while keeping its motion and performance, launched on 2 June 2025 on the Ray2 model. It offers three preset families — Adhere, Flex and Reimagine — from close retexturing to full reinterpretation. Luma now lists Modify Video V2 on its Ray3.2 model, for clips up to 20 seconds at 1080p (checked 3 October 2026). Q: How is Genjutsu different from Modify Video? A: Modify Video sets how much of the whole clip may change; Genjutsu sets what changes. You pick a mode — Replace character, Swap object, Change outfit, Change background or Free edit — and the engine is told to keep everything else. It suits edits where the rest of the shot must survive untouched, and it takes up to 30 reference images on Seedance 2.5. Q: What's the Genjutsu equivalent of Adhere, Flex and Reimagine? A: There isn't a strength setting. For an Adhere-style retexture of the whole clip, use Kenerate's Restyle Video tool with its 22 presets. For a Flex-style partial change, pick the Genjutsu mode for that target. For Reimagine-style transformations of a person, Replace character with a reference of the new being comes closest. Q: Can Genjutsu turn a person into a creature or robot? A: Yes, if you show it one. Add images of the creature, robot or costumed character, keep Replace character selected and write who becomes what. The knight demo above shows the idea. Very different body shapes are harder — a tall performer recast as a small round character — so pick references with a similar build. Q: Is Luma Dream Machine still available? A: Luma's own AI-facing information page calls Dream Machine and Ray2 deprecated and names Ray3.2 as its current video model, with Modify Video V2 inside it. If you used Modify Video on Ray2 and are looking for a replacement, compare current Luma plans with tools like Genjutsu on clip length and how targeted the edits are. Q: Is there a free Luma Modify Video alternative? A: Genjutsu needs no subscription, and new accounts get starter credits to try it. Each run is charged in credits per second of clip, read and returned, and failed runs are refunded automatically. You sign in with a verified email; every engine is available without a plan upgrade. Q: Is it OK to transform people in footage? A: Only with consent and the rights to the footage. Turning someone into a different character, changing their clothes or moving them somewhere else can mislead viewers, so edit only clips you own or licensed, only people who agreed, never celebrities, and label the result as AI-edited. ## Related pages - AI Video Editor: https://kenerateai.com/ai-video-editor - Runway Aleph alternative: https://kenerateai.com/runway-aleph-alternative - Kling O1 alternative: https://kenerateai.com/kling-o1-alternative - Video to video AI: https://kenerateai.com/video-to-video-ai - Luma Dream Machine alternative: https://kenerateai.com/luma-dream-machine-alternative ## Sources - Luma AI — Introducing Modify Video (2 June 2025): https://lumalabs.ai/news/introducing-modify-video - Luma API docs — Modify Video: https://docs.lumalabs.ai/docs/modify-video - Luma — official information for AI assistants (current models): https://lumalabs.ai/llm-info - Luma Learning Hub — Dream Machine Modify Video: https://lumalabs.ai/learning-hub/modify-video-dream-machine - Kenerate Genjutsu (video editor): https://kenerateai.com/app/genjutsu - Kenerate Restyle Video: https://kenerateai.com/app/tool/restyle-video
