The Concat video editor handles vertical video well. Picking 9:16 when you create the project saves a step, but it is not final: in our test of 0.2.7 we could switch an existing project to 9:16 later in the project settings, even though the new project dialog says those settings cannot be changed. Everything else works like a normal edit.
How do you make a vertical video in the Concat video editor?
- On the start screen click New project.
- Under Shape choose 9:16. With 1080p selected the frame is 1080 by 1920.
- Pick a frame rate. 30 fps is standard for TikTok. We used 25 to match our footage.
- Click Create, then import your clips and drag them onto the timeline.
How do you fill the frame with landscape footage?
Landscape clips land in the middle with empty space above and below. Click the clip, and in the right panel set Scale under Transform to about 316%. That fills the 9:16 frame with a 16:9 clip. Then drag the preview or change Position X to keep your subject in shot.
If you need the subject to move across the frame, click the keyframe button next to Position X at two points in time and Concat animates between them. See keyframes.
How do you add TikTok-style captions?
Click the T captions button on the timeline toolbar. Either switch on Use voice from timeline to transcribe the speech, or type a script. Choose Size: Large and click the button to add them. Concat splits the words into short phrases timed one after another.
For a bolder look, open the Text tab and try the Bold caption or Impact style.
What else makes a short video work?
- A hook in the first second. Cut the dead air with Q and W, which trim left and right of the playhead, the same keys as in CapCut.
- A voiceover. Type a script into Text to speech and Concat adds the audio to the timeline. See text to speech.
- Color. The Vivid filter in the Everyday group warms up flat phone footage.
How do you export for TikTok, Reels and Shorts?
Click Export. Keep the resolution at 1080 by 1920 and the codec at H.264 for the widest support, and choose Balanced quality. Our 1080p exports from the Concat video editor carried no watermark and uploaded as normal MP4 files.
If the export does not start, check our export stuck guide.
