Frames to Video AI — two images in, the motion between them out

Upload a start frame and an end frame, describe what happens between them, and the AI generates the clip that connects the two — a camera move, a transformation, a scene change or a seamless loop.

How do you turn two images into a video with AI?

Frames to video AI (also called first and last frame generation) takes two images — a start frame and an end frame — and generates the video between them: the clip opens exactly on your first image and lands exactly on your second, with the motion in between invented from your prompt. In Kenerate AI's Video Studio the image-to-video mode has two frame slots — "start frame required, end frame optional" — and 30 models take the end frame, including Kling, Wan, Seedance, Veo 3.1 and Vidu. A 5-second first-to-last-frame clip costs 105 credits on Kling v2.6 Pro, or 15 credits on Wan 2.2 Ultra Fast at 480p for a cheap draft.

How to use the frames to video AI

Time needed
Steps
4 steps
  1. Step 1

    Open Video Studio

    Pick image-to-video and a model that takes an end frame — Kling v2.6 Pro is a reliable default, Wan 2.2 Ultra Fast the cheapest draft.

  2. Step 2

    Upload your two frames

    The Frames panel has two slots: the start frame (required) and the end frame (optional). The clip will open on the first and land on the second.

  3. Step 3

    Describe the motion between

    Write what happens from frame one to frame two — the action, the camera move and the pace. The images anchor the ends; the prompt drives the middle.

  4. Step 4

    Set length and size

    5 seconds suits one clean move; longer gaps get 8–15 s. Pick the resolution and generate — credits are shown before you run.

Tips

Pick two frames the model can connect

The clip is only as believable as the gap between your images.

  • Keep both frames the same aspect ratio and a similar framing — a wide start and a close-up end forces an invented camera move.

  • Keep the subject, light and style consistent between the frames; the model preserves what matches and invents what doesn't.

  • Describe the journey in the prompt — "the camera pushes in while the flower opens" — not the two images themselves.

  • Say how the motion should feel: slow and smooth, a whip pan, a morph, a hard day-to-night shift.

  • For a seamless loop, upload the same image as start and end frame and describe a motion that returns home.

  • Draft at 480p or 720p on a cheap model first, then remake the keeper at 1080p or 4K.

FAQ

Frames to Video AI questions

What is frames to video AI?

It is video generation anchored by images at both ends: you supply the first frame and the last frame, and the model generates the motion that connects them. Unlike plain image-to-video, which only starts from your picture and improvises the rest, a frames-to-video clip also has to land exactly on your second image.

How do I turn two images into a video?

In Kenerate's Video Studio, pick image-to-video and a model with an end-frame slot, upload the first image as the start frame and the second as the end frame, then describe the motion between them — "the camera glides from the empty street to the lit shop window at dusk". Set the length, check the credits shown, and generate.

Which AI models support first and last frame?

In Kenerate, 30 video models take an end frame, including Kling v2.6 Pro and v3, Wan 2.2, 2.7 and 3.0, Seedance 1.x, 2.0 and 2.5, Veo 3.1, Vidu Q3 Pro, Hailuo 02 and LTX 2.5. Models that only take a start frame say "no end frame on this model" under the upload slot, so you can't pick wrong by accident.

How long can the clip between two frames be?

It depends on the model: Kling v2.6 Pro makes 5 or 10 s, Veo 3.1 makes 4, 6 or 8 s, Vidu Q3 Pro goes 1–16 s, and Wan 3.0 and Seedance 2.5 reach 30 s. Short clips stay closest to your two frames; the longer the clip, the more the model has to invent in the middle.

Do the two images need to match?

They should be related: same aspect ratio, similar framing and consistent style give the smoothest motion. The model can bridge bigger jumps — day to night, sketch to render, wide to close — but the further apart the frames are, the more the in-between is invented, and the more it helps to spell the transition out in the prompt.

Link to this answer

Can I use only an end frame?

No — the start frame is required and the end frame is optional. If you add a single image it becomes the start frame, and the studio asks for the end frame next. To steer a clip toward an image you only have as an ending, put that image first and describe the motion in reverse, or generate a matching start frame in the Image Studio.

How do I make a seamless video loop?

Upload the same image as both the start frame and the end frame, and describe a motion that comes back to rest — "steam curls up from the coffee cup and settles" — so the clip ends where it began and repeats without a visible cut.

Does the end frame cost extra?

No. A first-and-last-frame clip is billed like any image-to-video run of the same model, length and resolution — 105 credits for 5 s on Kling v2.6 Pro, 15 credits for 5 s on Wan 2.2 Ultra Fast at 480p. One quirk: Kling v2.6 Pro can't generate audio with an end frame, so those runs are billed and delivered silent.

Is frames to video free?

You can open Video Studio, upload both frames and see the exact credit price without paying. Generating video uses credits from a credit pack (from $15 for 1,300 credits); a free account's 25 sign-up credits are meant for images.

Can I chain clips into one longer video?

Yes — use clip A's last frame as clip B's start frame and each cut lands exactly where the last one ended. Generate the stills for your key moments first, then bridge them pair by pair and join the clips with the Video Joiner.

Frames to Video AI, explained

What works, what to avoid, and how to pick a model.

How first-and-last-frame generation works

Animators call it inbetweening: a lead artist draws the key poses and someone fills the frames between them. Frames-to-video AI is the same job done by a video model — your two images are the key frames, and the model generates every frame of the journey from one to the other, guided by your prompt.

That makes it the most controllable way to generate video. Plain text-to-video invents everything; image-to-video pins down only the opening shot. With both ends pinned, the model can't wander off: it has to open on your first image and arrive at your second.
