# How to make a TikTok video in the Concat video editor > Create a new project with the 9:16 shape (or switch an existing one in project settings), drop in your clip, scale it to about 316% if it is landscape footage, add Large captions and export. Concat adds no watermark. URL: https://concatvideoeditor.com/guides/make-a-tiktok-video Updated: 2026-10-18 Source: Concat Video Editor Guide, an independent guide. Not the official Concat website. 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? 1. On the start screen click **New project**. 2. Under **Shape** choose **9:16**. With **1080p** selected the frame is 1080 by 1920. 3. Pick a frame rate. 30 fps is standard for TikTok. We used 25 to match our footage. 4. Click **Create**, then import your clips and drag them onto the timeline. ![New project dialog in the Concat video editor with the 9:16 shape selected and 1080 by 1920 size](/images/feat-new-project.webp) ## 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](/features/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. ![Vertical frame exported from the Concat video editor with large white captions](/images/use-vertical-reel.webp) 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](/features/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](/guides/export-stuck). ## Videos ### Video: A 9:16 clip with large captions made in Concat Six seconds of a vertical 1080 by 1920 video exported from the Concat video editor with Large captions.

Click empty space on the timeline, then click Modify at the bottom of the Details panel. In the Project sheet, set Frame to 1080 × 1920 (9:16) and click Apply. The new project dialog says these settings cannot be changed later, but in 0.2.7 they can. ### What resolution should a TikTok export use? 1080 by 1920 at 30 fps is a safe choice for TikTok, Reels and Shorts. Concat can also export 1440p and 4K vertical video. ### Does the Concat video editor post directly to TikTok? No. Export the MP4 and upload it from the TikTok, Instagram or YouTube app.
