How to Turn Vimeo Videos into YouTube Shorts Clips

To convert a Vimeo video into YouTube Shorts clips, download your original file, then use Vidulk’s AI clipper to create vertical, captioned clips sized for Shorts.

Vimeo Video to YouTube Shorts Clips - How to Convert

Step 1: Download Your Vimeo Video

Start by downloading the original video file from your Vimeo account for the highest quality. This ensures your exported Shorts will look sharp and professional. Vimeo allows video owners to download their own uploads directly from the video settings.

Step 2: Understand YouTube Shorts Specifications

Length: Up to 3 minutes (for videos uploaded on or after October 15, 2024).
Aspect Ratio: Vertical (9:16) or square (1:1) is required for the video to count as a Short.
Resolution: 1080x1920 pixels for vertical videos.
Captions: YouTube auto-generates captions, but you can upload your own or edit them in YouTube Studio.

Step 3: Create Shorts Clips with Vidulk’s AI Clipper

Vidulk’s AI clipper (available for iOS and Android) simplifies the process:

Open Vidulk and upload your downloaded Vimeo video file.
The AI automatically finds the best moments - such as highlights, jokes, or key teaching points - and creates short clips.
Clips are exported in vertical (9:16) format with captions, matching YouTube Shorts requirements.
Review and adjust the clips as needed before saving to your device.

Step 4: Upload to YouTube Shorts

Transfer the exported vertical clips from Vidulk to your computer or directly to your phone.
Open the YouTube app or YouTube Studio and upload your clips as Shorts.
Check the aspect ratio and length to confirm they meet Shorts criteria. YouTube will auto-generate captions if your video language is supported, and you can edit these in YouTube Studio if needed.

Tips for Effective Shorts

Keep clips concise and engaging to maximize viewer retention.
Use clear, readable captions for accessibility and silent viewing.
Teasers from talks, interviews, or brand films work well as Shorts.

Vidulk's AI clipper (free to start, iOS + Android) finds the best moments in a long video and exports captioned vertical clips sized for the destination.
