Facebook Live to YouTube Shorts Clips - How to Create Short

1. Download Your Facebook Live Recording

Start by downloading your Facebook Live video from Meta Business Suite or Creator Studio. Facebook typically stores these in either 16:9 (horizontal) or 9:16 (vertical) formats. Make sure you have the highest quality version available for best results in editing.

2. Understanding YouTube Shorts Requirements

Length: Maximum 3 minutes per clip
Aspect Ratio: Vertical (9:16) or square (1:1) - anything wider, like 16:9, will not count as a Short
Resolution: 1080x1920 pixels (for 9:16 vertical)
Captions: YouTube auto-generates captions for supported languages, but you can upload videos with burned-in captions for clarity

3. Using Vidulk to Automate Clipping and Formatting

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

Import your downloaded Facebook Live video

Burned-in captions are added for accessibility and engagement
You can review, edit, and export the clips for upload

4. Uploading to YouTube Shorts

Once your clips are ready, upload them to YouTube from your device. Ensure each video is vertical or square and under 3 minutes. YouTube will automatically classify these as Shorts. You can further edit auto-generated captions in YouTube Studio if needed.
