Edit Video with AI: Change Anything in a Clip with a Prompt
AI video editing changes the content of footage itself — outfits, weather, style, objects — from a text instruction. Here is what prompt-based video editing can do in 2026 and how to run your first AI edit.
Edit Video with AI: Change Anything in a Clip with a Prompt
Classic video editors cut, arrange and color-grade footage. An AI video editor does something different: it changes what is in the frame. Type "make it snow", "put him in a tuxedo", or "turn this into an anime" and the model re-renders every frame of the clip with that change — consistently, across motion.
This is the video equivalent of prompt-based photo editing, and in 2026 it finally works well enough for real content.
What AI video editing can do today
- Restyle a whole clip — live footage to anime, clay, watercolor, or vintage film.
- Change wardrobe & appearance — outfits, hairstyles, accessories that track through movement.
- Rewrite the environment — weather, season, time of day, background city.
- Object edits — add or remove elements while the shot keeps playing.
- Speech & sound — change the words a speaker says with Lip Sync, or add a generated voice with the Voice Generator.
Engines like WAN video-edit and Kling's edit models (both available in Reelina's studio) keep the original motion and identity while applying your instruction.
How to edit a video with AI
- Open Edit Video with AI on Reelina.
- Upload the clip (short clips first — 5–15 seconds is the sweet spot).
- Type the change: "replace the daylight with neon night, keep everything else the same".
- Generate. Edits are priced per clip length; the exact coin cost shows before you run.
Prompts that behave well
- "Turn this into a 90s VHS home video, grain and date stamp"
- "Make her jacket bright red; don't change the face"
- "Same scene, but heavy rain and wet streets"
- "Anime style, keep the exact motion and framing"
One instruction per pass gives the model the best chance; chain passes for compound edits.
AI editing vs. classic editing — you need both
AI editing changes pixels; classic editing changes structure (cuts, music, pacing). A modern workflow: generate or shoot → AI-edit the look → cut and finish in your usual editor → upscale → add subtitles. Reelina covers every AI step in one place.
FAQ
Can AI edit an existing video? Yes — upload footage and describe the change; the edit is re-rendered across all frames, not pasted on top.
How much does AI video editing cost? Edits are billed per second of footage in coins, shown before you generate. The $9.99 Starter plan covers regular use.
Will faces stay consistent? Edit models are built to preserve identity and motion; say "keep the face unchanged" to make it explicit.
What is the best AI video editor? For prompt-based content edits, WAN and Kling edit models lead in 2026 — both run inside Reelina, so you can compare on your own clip.
