AI Video Combiner Online

Put one clip at the start and one at the end, and AI generates the shot that carries you from the first to the second — one continuous video, no editing timeline.

Source clip 1 — a dancer in a studio
Source clip 2 — an empty rooftop at sunset

Two clips, one continuous shot

Your first clip opens the video and your second one closes it. Everything between them is generated — the camera keeps moving, the scene keeps going, and the two arrive as one take instead of two files butted together at a cut.

Two clips become one shot

The join is generated, not cut

A normal merge leaves a hard edit where one clip ends. Here the model is conditioned on both ends of the timeline at once, so it builds the frames that get from one to the other — light, colour and motion carried through rather than jumping.

Light and colour are matched

Runs in your browser

Nothing to install and nothing to render locally. Upload from the phone you filmed on or the laptop you are already working at — the work happens on our side and comes back as a normal video file.

You set ratio, length and quality

Pick 16:9, 9:16 or 1:1 before you start, choose how long the finished video runs, and pick 480p or 720p. The choice travels with the run, so you are not re-exporting afterwards.

How to join two videos into one

1

Upload the clip that opens

Drop the clip you want the video to start on into slot 1, or click to browse. A still photo works too. Up to 20 MB per file.

2

Upload the clip that closes

Add the clip you want it to end on into slot 2. These two become the head and the tail of one timeline.

3

Say what happens in between

Write one line describing the shot that carries you from the first clip to the second, e.g. "the camera pulls back off the dancer and drifts across the rooftop". Leave it empty and a neutral default is used.

4

Press Combine Videos

Set the ratio, length and quality if you want them, then hit Combine Videos. You land in the Overchat video studio with both clips and your instruction already loaded, and the run starts there.

Who the AI video combiner is for

🎬

Content creators

You shot the take and you shot the location on different days. Put yourself into the scene instead of reshooting when the light was already gone.

📱

Social media managers

A brand clip and a stock backdrop arrive as two separate files. Merge them into one vertical shot for the feed without booking an editor.

🛍️

Product marketers

Drop the product clip into a real environment — a kitchen, a street, a gym — instead of paying for another location shoot.

🧩

Small teams without an editor

No timeline, no keyframes, no green screen. Two uploads and a sentence describing what should end up in frame.

🌍

Travel and event filmers

Your subject clip and your establishing shot never quite match. Let AI relight one into the other so the pair reads as one camera.

💡

Anyone testing an idea

Try the shot before you commit to filming it — a rough combine tells you in a minute whether the concept holds up.

I like how it keeps everything organized. One subscription is enough for all major AI models, which helps me avoid paying for multiple platforms.

I've started to use overchat last week and it feels very promising. Lots of AI models in one place saves a lot of money in comparison if you buy subscriptions for each one.

Frequently Asked Questions

How do I combine two videos into one?

Upload the clip you want the video to start on, then the one you want it to end on, and press Combine Videos. You are taken into the Overchat AI video studio with both clips and your instruction already loaded, and the run starts there. A join usually takes about a minute.

Does it just stick the two clips together at a cut?

No — there is no cut. Both clips are pinned to positions on one timeline and the model generates the frames in between, so the camera and the scene carry through from the first clip into the second. You get one continuous shot rather than clip A followed by clip B.

What file types and sizes can I upload?

Any video your browser can read — MP4, MOV, WebM — and still photos as well, including HEIC from an iPhone. Each file has to be under 20 MB, so trim a long clip down to the few seconds that matter before uploading.

Can I use a photo instead of a clip?

Yes. Either slot takes a photo or a video, so you can open on a still and close on footage, or the other way round. A photo is treated as a single frame pinned to that end of the timeline.

Is it free?

You can build the whole thing here without an account — upload both clips, write the instruction, pick your settings. Running it happens inside Overchat AI and costs credits, so you sign in at that point. New accounts start with free credits.

Will my audio be kept?

Not from the source clips. The output is newly generated footage, so it does not carry the audio tracks on your uploads. If a specific voice or music matters, lay it back over the result in your editor.

How long can the finished video be?

Four to eight seconds, set before you start. Short is deliberate: the whole thing is one generated shot rather than an edit, and it holds together best in that range.

Do you keep my videos?

Your uploads go to Overchat AI storage so the model can read them, and the finished video lands in your account history where you can download or delete it. Do not upload footage you do not have the rights to use.
