To change your CapCut video to TikTok size, you need to adjust its aspect ratio to 9:16 within the CapCut editor, then position and fill the background as desired. This ensures your video fits perfectly on TikTok's vertical, full-screen display.
Why TikTok's 9:16 Aspect Ratio is Key
TikTok is designed for vertical video consumption, meaning its native player is optimized for videos with a 9:16 aspect ratio. This ratio means the video is taller than it is wide, filling the entire screen of most smartphones when held vertically. Using the correct aspect ratio prevents your video from appearing with black bars on the sides (if it's 16:9 horizontal) or being awkwardly cropped.
Step-by-Step Guide to Resizing Your Video in CapCut
CapCut makes it straightforward to adapt your existing videos for TikTok. Follow these steps for a seamless transition:
- Open CapCut and Start a New Project: Launch the CapCut app on your device. Tap on "New project" to begin, then select the video(s) you wish to edit from your gallery and tap "Add."
- Upload Your Video: Your chosen video clips will be imported into the CapCut timeline, ready for editing.
- Select the TikTok Aspect Ratio (9:16):
- On the main editing timeline, look for the "Ratio" option at the bottom toolbar.
- Tap on "Ratio" and then select "9:16". This instantly sets your project's canvas to the TikTok-preferred dimension.
- Adjust Your Video: Once the 9:16 ratio is applied, your video might not perfectly fill the new frame, especially if it was originally shot in a different aspect ratio (like 16:9).
- Pinch and Zoom: Use two fingers on the video preview to zoom in or out, or drag it to reposition it within the 9:16 frame. Focus on keeping the most important elements visible.
- Rotate: If your video was shot horizontally, you might need to rotate it to fit the vertical frame better.
- Utilize the Canvas/Background (If Desired): If your video doesn't completely fill the 9:16 frame after adjustment (leaving empty space at the top/bottom or sides), CapCut offers options to enhance the background:
- Select the video clip on the timeline.
- Scroll through the bottom toolbar and tap on "Canvas."
- Here, you can choose to:
- Blur: Apply a blurred version of your video to the background.
- Color: Fill the empty space with a solid color.
- Background: Add a custom image from your gallery as the background.
- Export Your TikTok-Ready Video: Once you're satisfied with the video's appearance in the 9:16 ratio, tap the export icon (usually an upward arrow) in the top right corner. You can adjust the resolution and frame rate before saving the video to your device, which is then ready to be uploaded directly to TikTok.
Advanced Tips for Optimal TikTok Video Sizing
- Shoot Vertically: The easiest way to ensure your video fits TikTok perfectly is to film it in a vertical (portrait) orientation from the start.
- Auto Reframe: Some video editing tools, including potentially CapCut in advanced versions, offer an "Auto Reframe" feature that intelligently adjusts your video's framing for different aspect ratios. Always review the results carefully.
- Cropping vs. Canvas: Understand the difference. Cropping cuts off parts of your video to fit the new ratio, while using the Canvas feature adds a background behind your video without losing original footage. Choose based on whether losing parts of your original video is acceptable.
- Preview Before Exporting: Always watch your entire video within CapCut's 9:16 preview window before exporting to catch any awkward crops or misalignments.
- Text and Stickers: Use CapCut's text and sticker features to fill any remaining negative space or add context without cluttering the main subject of your video.
