Step‑by‑Step with FlexClip (PC or Mac)
- Upload and Set Aspect Ratio
Navigate to FlexClip and import your YouTube video from your computer, Google Drive, Dropbox, or OneDrive. Set the aspect ratio to 9:16 to match TikTok’s vertical layout. - Place Your Video on the Timeline
Click "Add as Layer" to drag the clip onto the timeline. Stretch the corners so the video fills the frame. If you need to keep the original 16:9 footage, add an animated background from the Background tab, layer your video on top, and center it. - Enhance with Text and Captions
Use the Text tab to choose from 1,000+ animated text styles—lower thirds, callouts, quotes, and more. For captions, go to the Subtitle tab, select "Auto AI Subtitle," choose your language, and generate burned‑in subtitles with up to 95% accuracy. Proofread and adjust font, color, and timing as needed. - Add Music and Effects
Click the Audio tab to search 74,000+ royalty‑free tracks or upload your own. Browse the Photo and Elements tabs for GIFs, stickers, and animated overlays that align with TikTok trends. - Export or Upload Directly
Click "Export" to download the finished video to your PC, or hit the TikTok icon for a one‑click upload. You can also share the file to cloud services or generate a shareable link for newsletters and blogs.
Repurposing on Mobile with CapCut
- Open CapCut, tap "New Project," and import your YouTube clip.
- Tap "Format," select 9:16; CapCut automatically centers the original 16:9 footage within the vertical frame.
- Use "Canvas → Blur" to replace the black background with a blurred version of your own video, giving it a polished look.
- Trim, split, and add text or stickers as needed.
- Export and then tap "Share to TikTok" to open the TikTok app and post your video.
Key Considerations Before Uploading
- Length & Aspect Ratio – TikTok clips run from 15 to 60 seconds in 9:16. Trim or split longer YouTube videos to highlight the most engaging moments.
- Content Fit – YouTube’s depth (reviews, podcasts, documentaries) differs from TikTok’s quick, entertainment‑centric format. Choose segments that resonate with Gen Z’s appetite for fast, visual storytelling.
- Audience Alignment – While YouTube spans all ages, TikTok’s majority are Gen Z. Tailor your TikTok cut to match platform trends and viewer expectations.
