Best AI image-to-video generators

Key takeaways

• Melius is the pick when different shots need different models. One subscription covers Veo 3.1, Seedance 2.0, Kling 3.0 Omni, Wan 3.0 and more, and Mel, the Melius agent, sends each shot to the model that suits it.
• Kling 3.0 is a strong all-rounder, with start and end frames, up to seven reference images on its Omni variant, 15-second clips and native audio.
• Google Flow runs Veo 3.1 with sound on every clip and renders vertical video natively.
• Luma's Ray3.2 gives the finest control over motion, with up to 16 keyframes across a clip.
• Start frame and reference image are different controls. One animates your photo itself; the other keeps a subject consistent in a new shot.

What is the best AI image-to-video generator?

The best AI image-to-video generator is the one that keeps your photo intact while it moves, and lets you decide where the clip ends. Melius suits creators whose shots need different strengths, because it puts the leading video models in one place and Mel, its agent, routes each shot to the one best at it. Kling 3.0 is the strongest single model for control and length, Google's Flow adds native sound to every Veo 3.1 clip, Runway handles complex camera moves from a prompt, Luma is the most precise on motion, and Adobe Firefly puts several models in one workspace.

We ranked these seven on five things: whether a tool supports both a first and a last frame, whether it takes reference images, how long and how sharp a clip can be, whether it generates sound, and whether it makes true vertical video for social. Price isn't a ranking factor here, because plans and credit costs change often.

What to know before you pick

• A starting frame animates your photo itself. The clip opens on your exact image and moves from there. A reference image is looser: the model matches the subject or style across a new shot without pinning any frame to it.
• The last frame is the control most people miss. Pinning where the clip ends stops the model drifting away from your subject mid-shot, and it's how you make a clip loop or land on a specific pose.
• Most clips run 5 to 15 seconds. Longer videos are several clips chained together, each starting where the last one ended.
• Sound isn't standard yet. Kling, Veo 3.1 and PixVerse generate audio with the picture. Runway's Gen-4.5 and Luma's Ray3.2 make silent clips.
• Make vertical video vertical from the start. Generating at 9:16 keeps the subject in frame. Cropping a widescreen clip for Reels or TikTok usually cuts off part of the subject.

The seven compared

1. Melius - the right video model for each shot

Melius is the AI-native operating system for creatives. You brief Mel, the Melius agent, with your photo and the shot you want, and Mel builds the clip on one canvas, with the photo as the starting frame, the last frame or a reference, depending on the shot.

What sets Melius apart is the range of video models behind it, because each one moves an image differently. Our library of leading models includes Veo 3.1 for cinematic motion, environments and products in motion; Seedance 2.0 for people and characters, with synchronized audio; Kling 3.0 Omni for keeping a character or product consistent from reference images; Wan 3.0 for longer shots, up to 30 seconds with sound; Flux 3 for filling in the motion between a first and a last frame; and LTX 2.5 for output up to 4K. A product reveal and the shot of the person holding the product can each go to a different model, picked because it handles that shot well.

Mel does the routing. It picks the model for each shot, sets up the frames, writes the motion prompt and runs the takes, so you don't need to know which models accept a last frame or which ones are less dependable with faces. You stay the director: every prompt stays editable, you can ask Mel to rerun a shot on another model and compare, and one clip's last frame can become the next clip's starting frame.

What Melius does well

• Puts the leading video models under one subscription, so each shot can come from the model that handles that kind of motion best.
• Lets Mel choose the model and wire the frames, so you get the right setup for each shot without learning every model's inputs.
• Runs the same photo through more than one model when you ask, without re-uploading it or switching tools.
• Pins both the first and the last frame on models that support it, and keeps a character consistent across shots with the same reference image on each.
• Drafts Seedance 2.5 clips at 480p and upscales the keeper to 1080p, covers every social ratio including 9:16, and turns a still into a boomerang clip with the Image to Boomerang template.

The trade-off with Melius

Length, resolution and sound depend on the model each shot runs on, so the same photo can give you a few seconds on one model and 30 seconds with sound on another.

Best for: Creators and teams who want each shot made by the model best suited to it, routed by the Melius agent.

2. Kling 3.0 - control, length and sound

Kling is Kuaishou's AI video platform, and Kling 3.0, released in February 2026, is its current generally available model. It animates a start frame toward an optional end frame, and its Omni variant takes up to seven reference images or elements. Kling 4.0 was announced on September 28, 2026 and is still rolling out.

What Kling 3.0 does well

• Supports start and end frames, plus reference images on Omni.
• Runs clips up to 15 seconds at up to 1080p, with native audio.
• Plans multi-shot sequences with per-shot framing, angle and camera movement.

The trade-off with Kling 3.0

Reviewers report long queues at peak times and generations that fail but still use credits. Free-plan credits come with watermarked output.

Best for: Creators who want the most control from a single model.

3. Runway Gen-4.5 - camera moves from a prompt

Runway is an AI video company, and Gen-4.5 is its own flagship model, with image-to-video added in January 2026. It starts from a first frame and handles detailed camera choreography described in a single prompt. Runway also hosts other labs' video models, including Kling 3.0, in the same app.

What Runway Gen-4.5 does well

• Follows complex camera directions written into the prompt.
• Outputs vertical 9:16 alongside 16:9, 1:1, 4:3, 3:4 and 21:9.
• Upscales to 4K on paid plans.

The trade-off with Runway Gen-4.5

Gen-4.5 generates 2 to 10 seconds at 720p, with no native audio and no last-frame control, and it needs the Standard plan or higher.

Best for: Shots where the camera move matters more than the clip's length or sound.

4. Google Flow (Veo 3.1) - image-to-video with sound

Flow is Google's AI filmmaking app, where Veo 3.1 runs alongside Google's newer Gemini Omni Flash model. Its Frames to Video mode animates an image toward an optional last frame, and Ingredients to Video takes up to three reference images. Every Veo 3.1 clip comes with generated sound: dialogue, effects and ambience.

What Flow does well

• Generates audio with every clip.
• Renders 9:16 vertical video natively, so nothing is cropped from a widescreen frame.
• Gives every user 50 free credits a day.

The trade-off with Flow

Clips run 4, 6 or 8 seconds, and 1080p, 4K and reference images all require the 8-second length. Longer shots are built with extensions, which add 7 seconds at a time at 720p.

Best for: Short social clips that need sound and a true vertical frame.

5. Luma Ray3.2 - precise motion

Luma is an AI video lab, and Ray3.2, released on June 9, 2026, is its newest video model. Instead of a single start and end frame, it takes up to 16 keyframes across a clip, and Camera Motion Transfer copies a camera move from one video onto another. It outputs native 16-bit HDR with EXR export for grading.

What Luma Ray3.2 does well

• Places up to 16 keyframes, not only the first and last.
• Exports 16-bit HDR and EXR for color work.
• Supports 9:16 alongside 3:4, 1:1, 4:3, 16:9 and 21:9.

The trade-off with Luma Ray3.2

Image-to-video clips run 5 or 10 seconds with no native audio, and there's no free plan.

Best for: Creators who want to choreograph the motion beat by beat.

6. Adobe Firefly - several models in one workspace

Adobe Firefly's Generate Video takes a first frame and an optional end frame, with camera presets for pan, zoom and tilt. Its model picker includes Adobe's own Firefly Video Model alongside partner models: Veo 3.1 Fast, Luma's Ray3.14, Runway Gen-4.5 and Kling 3.0.

What Firefly does well

• Puts several leading video models behind one interface.
• Has camera presets, so the move doesn't depend on the prompt alone.
• Starts free with daily generations on the Firefly Video Model, without a watermark.

The trade-off with Firefly

Adobe's own Firefly Video Model makes clips of about five seconds without sound. The longer, audio-capable models in the picker are partner models. Free accounts get a few of them, and a paid plan unlocks more of them and more generations.

Best for: Creators already in Adobe's apps who want a few models in one place.

7. PixVerse V6 - a free start with sound

PixVerse is an AI video platform, and V6, released on March 30, 2026, is its current model. It animates an image with a first and last frame transition mode, fuses reference images into a new clip, and generates audio together with the video, including across multiple shots.

What PixVerse V6 does well

• Generates audio and video together.
• Runs clips from 1 to 15 seconds in 9:16, 16:9, 1:1 and other ratios.
• Has a free Basic plan with daily credits.

The trade-off with PixVerse V6

PixVerse says precise directional control in complex scenes is still evolving, and its entry paid plan caps resolution at 720p.

Best for: Trying image-to-video before paying for anything.

How to turn a photo into a video for social media with AI

The same few decisions make most photo-to-video clips work, whatever tool you use.

1. Pick a photo with room to move. A subject with space around it gives the model somewhere to take the camera. A tight crop leaves it nowhere to go.
2. Set 9:16 before you generate. Reels, TikTok and Shorts are vertical, and a clip made vertical keeps the subject in frame.
3. Use the photo as the starting frame. That keeps the person or product exactly as photographed at the start of the clip.
4. Say what moves and what stays still. A slow push-in with the subject's face unchanged is a clearer instruction than a request for something cinematic.
5. Keep it short and add sound. Five to eight seconds suits most social posts, and a model with native audio saves a step.

Turning an image into video on Melius

Most clips on Melius start with a brief to Mel and end with a few notes back. A brief that gets the motion right covers these points.

1. Drop the photo on the canvas and describe the shot. Say what moves, what has to stay unchanged and how the camera travels: a slow push-in on the product, the subject turning toward the lens.
2. Say where it's going. Name the platform and the length, so Mel sets 9:16 for Reels or TikTok and picks a model that can run that long.
3. Say how the clip should end. Add a second image if the shot should land on a specific frame, and Mel uses a model that accepts a last frame.
4. Name a model if you have one in mind. Otherwise Mel picks for each shot, and you can ask for the same photo on a second model, or a 480p draft on Seedance 2.5 to test the motion first.
5. Review, then direct. Tell Mel what to change or edit the one prompt that's off, then chain the winner into the next shot or cut it in the multi-track editor.
