# Frames to Video 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.

## Key facts
- Input: A start frame + an optional end frame
- Models with an end-frame slot: 30 (Kling, Wan, Seedance, Veo, Vidu…)
- Clip length: 1–30 s, by model
- Top resolution: 4K (Seedance 2.5, Veo 3.1, LTX 2.5)
- Cheapest test: Wan 2.2 Ultra Fast, 5 s at 480p = 15 credits
- Loop trick: Use the same image as start and end frame
- Start frame only?: Works too — that's plain image-to-video
- End frame only?: No — a single image is always the start frame

## Steps
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. 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. 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. 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.
5. Check the landing — Make sure the clip really arrives on your end frame. If it drifts, simplify the prompt or bring the two frames closer together.

## In depth

### 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.

### What two frames can do
The pattern covers more than one effect:
- Transitions: a product in the box → the product in use; a room empty → furnished; summer → winter.
- Camera moves that land somewhere exact: wide establishing shot → the detail you want the viewer to end on.
- Transformations: a sketch → the finished render; a cocoon → the butterfly; young → old.
- Seamless loops: the same image at both ends with a motion that returns home.
- Scene-to-scene cuts for longer edits: each clip ends on the still the next clip starts from.

### Where do the two images come from?
Any two stills work: photos, renders, anime art or paintings. The cleanest pairs come from the Image Studio — generate the start frame, then edit it ("same scene at night", "the vase now full of tulips") so the second frame matches the first in style, framing and aspect ratio, and the video model only has to animate the difference.

### What can go wrong
The middle of the clip is generated, not captured, so the usual AI video caveats apply between your anchors: faces and logos can drift mid-motion, and if the two frames are too far apart the model may cut, morph or teleport instead of moving smoothly. A shared aspect ratio, a related framing and a prompt that names the one motion you want fix most of it — and a 15-credit draft on Wan 2.2 Ultra Fast tells you whether a frame pair works before you spend on 1080p or 4K.

## FAQ
Q: What is frames to video AI?
A: 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.

Q: How do I turn two images into a video?
A: 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.

Q: Which AI models support first and last frame?
A: 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.

Q: How long can the clip between two frames be?
A: 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.

Q: Do the two images need to match?
A: 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.

Q: Can I use only an end frame?
A: 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.

Q: How do I make a seamless video loop?
A: 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.

Q: Does the end frame cost extra?
A: 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.

Q: Is frames to video free?
A: 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.

Q: Can I chain clips into one longer video?
A: 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.
