Step 1
Open the video studio
Go to Video and pick Join clips — the Video Joiner. It needs no prompt, so the prompt box disappears.
Step 2
Add 2–4 clips
Upload MP4s or pick clips you already made in the studio. Add them in the order they should play; the studio asks for at least 2.
Step 3
Check the price and create
40 credits for 2 clips, 80 for 3, 120 for 4. The job runs in the background and lands in your Video history.
Step 4
Download the merged MP4
Open the result and download it — no watermark is added.
See it in the app
Open Video Studio in Text to Video mode and write the shot — subject, action, camera move and light.

Video Joiner or Agent montage?
Both give you one MP4; they differ in how many clips and how much control.
| Video Joiner | Agent montage | |
|---|---|---|
| Clips | 2–4 | 2–20, up to 3 minutes total |
| Credits | 40 · 80 · 120 | 3 for 2 clips, +1 per extra clip |
| Trim clips | No | Yes, start and end in seconds |
| Music / voiceover | No | Yes, mixed under or over the clips |
| Transitions | AI join | 0.35 s fades or hard cuts |
| Where | Video studio | Kenerate Agent chat |
The montage scales and pads every clip to one frame (1280×720, 720×1280 or 1080×1080), so mixed sizes still join; each clip can be up to 250 MB.

Tips
Merges that don't look stitched
What makes separate clips play as one video.
Match the aspect ratio before you join — mixing 9:16 and 16:9 leaves bars or crops.
Keep the resolution and frame rate the same where you can; the montage fits everything to one frame at 30 fps.
Order clips by action: wide establishing shot, then closer action, then a closing shot.
Trim dead frames at the start and end of each clip (Agent montage takes trims in seconds).
Use soft fades between unrelated shots and hard cuts on matching action.
Make clips with the same model and lighting when they should feel like one scene.
FAQ
Merge videos online — questions
9 questions
How do I merge videos online?
In Kenerate's video studio choose Join clips, add 2–4 clips in playing order and press Create. You get one MP4 in your Video history. For more than 4 clips, ask Kenerate Agent for a montage of up to 20.
Link to this answerHow many videos can I merge at once?
The Video Joiner takes 2 to 4 clips per join. Kenerate Agent's montage takes 2 to 20 clips, up to 3 minutes in total. You can also merge a merged video again with new clips.
Link to this answerCan I merge videos online for free?
Not in Kenerate. The Video Joiner costs 40–120 credits and the video studio is on the paid plans; an Agent montage costs 3 credits for 2 clips plus 1 per extra clip. Browser editors such as Clipchamp or CreatorKit offer free merging if you don't need AI.
Link to this answerWill the merged video have a watermark?
No. Kenerate doesn't add a watermark to merged videos or montages.
Link to this answerCan I merge videos without signing up?
No — merging spends credits, so you need a Kenerate account. Your merged videos are saved to your Video history.
Link to this answerCan I trim and merge videos online?
Yes, with an Agent montage: give each clip a start and end time in seconds and it trims before joining. The Video Joiner uses the clips as they are, so trim them first if needed.
Link to this answerCan I add music when merging videos?
Not in the Video Joiner. An Agent montage can mix a music track and a voiceover under the clips — make the track in Kenerate's music studio first or upload your own, then ask the agent to use it.
Link to this answerWhat if my clips have different sizes?
The montage scales and pads every clip to one frame — 16:9, 9:16 or 1:1 — at 30 fps, so mixed sizes still join, with black bars where shapes differ. For the cleanest result, make or crop all clips to the same ratio first.
Link to this answerIs merging the same as extending a video?
No. Merging joins clips you already have. An AI video extender generates new footage that continues one clip — use it when a single shot needs to run longer.

What makes merged clips look like one video
On this page
Matching clips merge best
Clips with the same resolution and frame rate join without jumps in sharpness or motion [1]. Kenerate's montage fits every clip to one frame at 30 fps so a mix of models and shapes still plays, but black bars appear where a clip's shape differs from the frame.
Order is the edit
A merge has no story of its own — the order does the work. A common pattern is wide, medium, close, then a closing shot; clips that continue the same action (a rider, then the same rider closer) read as one scene.
- Open with a wide or establishing shot
- Cut on movement, not on a still moment
- End on a calm shot so the video doesn't stop abruptly
Sound across the joins
Each clip's own sound changes at every join. A single music track or voiceover across the whole video hides those changes, which is why the Agent montage mixes one soundtrack over the clips when you give it one.
Merge videos online without watermark
Both the Video Joiner and Agent montages download as plain MP4s with no Kenerate watermark.
Merge videos online and add music
Ask Kenerate Agent for a montage with a music track: it lowers the music under a voiceover automatically and fades it out at the end.
Trim and merge videos online
Agent montages take a start and end time for each clip, so you can cut dead frames and join in one step.
AI video merger vs a timeline editor
A timeline editor gives frame-level control; an AI merger is faster when you just need clips in order — upload, order, done.
