How I Use CapCut for Facebook Live Highlights
In this section, I’ll walk through the exact workflow I use when turning long-form content into short clips using CapCut. This process is especially helpful when working with Facebook Live replays, webinars, or interviews, and it ties directly into my usual Long Video to Shorts editing routine.
Step 1: Upload Your Video
I start by opening the CapCut Long Video to Shorts tool and uploading my footage. I can either drag and drop the file directly or import it from cloud storage platforms like Google Drive or Dropbox.
During this step, I always make sure the page stays open until the upload is fully completed to avoid interruptions or failed processing. This ensures CapCut can properly analyze the entire video for highlight detection.
Step 2: Generate Short Clips
Once the upload is complete, I choose my preferred clip length and define any time segments I want to prioritize. This is where CapCut’s AI really shines, as it automatically scans the entire video and identifies the most engaging moments.
The system then generates multiple short clips based on those highlights, which makes it incredibly efficient as a long video to shorts with auto subtitles workflow. This step alone saves me hours compared to manual trimming, especially when repurposing long livestreams or interviews.
If you're learning how to make a long video into a short video with CapCut, this is the stage where the automation does most of the heavy lifting.
Step 3: Preview, Edit, and Export
After the clips are generated, I preview each one to ensure the pacing, framing, and subtitles look natural. If I want to refine anything, I click “Edit More” to adjust timing, add captions, include transitions, or enhance the video with background music.
Once everything looks good, I export the clips directly to my device or publish them to platforms like TikTok, YouTube Shorts, or Instagram Reels. This final step completes the long video to shorts transformation, turning raw footage into polished, ready-to-share content in just minutes.
Conclusion
Overall, CapCut remains my first choice when working with long-form video content because it simplifies everything from clipping to subtitles while maintaining consistent output quality. Compared to other tools that focus on narrower functions, CapCut delivers a more complete AI-driven workflow for short-form content creation, especially for creators who need speed and scalability.
If you’re looking for a reliable long video clipper or want to scale short-form production efficiently, I would personally start with CapCut. The experience inside the CapCut online video editor makes the entire process even smoother, from upload to final export, especially when handling frequent content repurposing workflows.
