Ten clips in, one file out
Video Merger
Join up to ten generated clips into one continuous video. Different sizes, different frame rates, half of them silent — all of it normalised before the join.
Three shots, one video:
A merge costs 10 credits whatever its length, refunded automatically if the job fails. Credits come from a WowMade plan, from $25 a month. Plans renew monthly until cancelled and can be cancelled online at any time — see pricing details.
Why a generated video is almost always several videos
Generative engines render a shot, not a film. Five, ten, fifteen, sometimes thirty seconds — then it stops, because holding a coherent scene together gets exponentially harder the longer it runs. So anything with a beginning, a middle and an end is a handful of separate files that need to become one, and doing that by hand means opening an editor to perform a single operation.
The merger is that one operation. Pick the clips, set the order, spend ten credits, get one file back. The awkward part — that your clips almost certainly disagree about resolution, aspect ratio, frame rate and whether they have sound, because they came off different engines — is handled before the join rather than left to fail halfway through.
Three separate generations
Each of these was generated on its own from the prompt beneath it. Nothing about them was planned to match.

The clip beside this is those three, in that order, run through exactly the merge the tool performs — one 1080p file, one continuous timeline, one audio track. It is not a fourth generation made to look like a join.
From here it behaves like any other video in your library: score it in the music studio, take it up to 4K in the video upscaler, or merge it again with the next three shots.
What gets normalised before the join
Concatenating video is only trivial when every input already agrees. These never do — one clip came off an engine that renders 4K with native audio, the next off one that caps at 720p and is silent. Each row below is a mismatch the merger resolves on its own.
| Property | What arrives | What the merger does |
|---|---|---|
| Canvas | Clips at 4K, 1080p and 720p | Scaled to fit the first clip's shape, capped at 1080p |
| Aspect | 16:9 mixed with 9:16 | Padded to fit, never cropped — nothing leaves the frame |
| Frame rate | 24, 25 and 30 fps in one batch | Conformed to a single 30 fps timeline |
| Audio | Some clips silent, some with native sound | Silent clips get a generated track so no audio is lost |
| Codec | Whatever each engine wrote | Re-encoded once to H.264, then joined without a second pass |
Normalisation happens once, then the clips are glued without a second re-encode — so quality is spent one time rather than compounding across the batch.
How it works
Pick the clips and the order
Up to ten from your library, in the sequence you want them played. Order is the only creative decision the merger asks you for.
Merge
Ten credits. Every clip is conformed to one canvas, one frame rate and one audio layout, then joined. A failed job refunds itself rather than leaving the charge in place.
Finish it
The merged file lands back in your library ready to download, to score, to upscale, or to merge again if the piece needs to run longer than ten clips.
Only your own material, and it stays marked
The merger accepts clips that are already in your WowMade library — things you generated here, or media you uploaded through the platform and which passed its checks. External links are rejected outright. That is a deliberate limit rather than a missing feature: a general purpose joiner that accepts anything is a way to assemble material the platform would have refused to generate, and this one is not that. The content and safety policy sets out what is allowed on the platform at all.
The output is AI-generated and carries a signed C2PA provenance manifest saying so, naming the tool that produced it. Joining clips does not strip the marking, and anyone can read it back on the verification page.
Frequently asked questions
The details worth knowing before the first merge.
What does the video merger do?
It joins several clips into one continuous file, end to end, in the order you set. Generated clips are short by nature — five to thirty seconds each — so anything longer than a single shot is really a sequence of them, and the merger is what turns that sequence into one video you can post, send or upload.
How many clips can I merge at once?
Up to ten in a single merge, and the result can itself be merged again if a piece needs to run longer than that. There is a total size ceiling on the inputs to keep the job inside its time budget, which in practice ten generated clips comfortably fit under.
What if my clips are different sizes or frame rates?
That is handled for you and it is the part that makes this worth using rather than doing by hand. The first clip sets the canvas — capped at 1080p — and every other clip is scaled to fit inside it, padded rather than cropped so nothing is cut off, and conformed to 30 frames per second before anything is joined.
What happens to clips that have no sound?
They get a generated silent track before the join. This matters more than it sounds: concatenating a silent clip with a clip that has audio, without doing this, drops the audio from the whole output. Mixing engines with native sound and engines without is normal here, so the merger assumes it.
How many credits does a merge cost?
Ten credits per merge, regardless of how many clips go into it, and the charge is refunded automatically if the job fails. Credits come from a WowMade plan or a credit pack, and one balance covers video, images and music.
Can I upload footage from somewhere else to merge?
The merger only accepts files that are already on your WowMade library — clips you generated here, or media you uploaded through the platform and which passed its checks. Arbitrary external links are rejected. It is a deliberate limit: it keeps material the platform would refuse to generate from being assembled here instead.
What resolution and format does the merged file come out at?
MP4, H.264, 30 frames per second, at the shape of your first clip up to a maximum height of 1080p. A merge is something you share rather than a mastering step, and capping the canvas keeps even a ten-clip job from timing out. If you need the result larger, run it through the video upscaler afterwards.
Is the merged file still marked as AI-generated?
Yes. The output carries a signed C2PA provenance manifest identifying it as AI-generated and naming the tool that produced it, in line with Article 50 of the EU AI Act. Merging generated clips does not strip that marking, and anyone can read it back on the verification page.
