Turn a 1-hour livestream into 5 viral shorts by EOD. Stop editing frame-by-frame. Use this AI workflow to batch-produce clips with ready-to-post copy in 30m!
Got a 1-hour skincare livestream replay, and your boss wants 5 highlight short videos before the end of the day, complete with ready-to-post Xiaohongshu copy. In the past, scrubbing through footage frame by frame in Premiere Pro or CapCut Pro, manually marking timestamps, and extracting subtitles would eat up half your day. Today, using this AI video editing workflow, I brewed a cup of coffee, and by the time I finished, 5 highly engaging short videos were already sitting in my drafts folder. Let me walk you through the hands-on process.
Don't just dump hundreds of megabytes of raw footage into the software. I first use a lossless compression tool to convert the livestream recording into a 1080P MP4 with a moderate bitrate. Why do this? Because the core of AI video editing is "understanding" the visuals and audio. Files that are too large will slow down cloud analysis, while over-compression will lose visual details. Preparing a clear 1080P version is the prerequisite for running the entire workflow efficiently.
After importing the video, instead of choosing "split evenly by time," I select "Semantic Highlight Extraction." In the prompt, I enter: "Extract clips where the host explains core selling points, shows high emotion, or demonstrates before-and-after comparisons. Keep each clip between 30-45 seconds."
Here, I must mention a competitor comparison. Some tools on the market can only clip by "removing silence," resulting in videos full of filler talk and water-drinking shots. Our AI video editing tool actually understands business logic, accurately capturing high-conversion moments like "Pro-Xylane anti-aging," completely eliminating the pain of manually watching replays to find highlights.
Once the AI generates 5 clips, it creates a rough cut with one click. The frames are automatically cropped to 9:16, and dynamic subtitles are added.
Here's a real pitfall you'll encounter: AI speech recognition goes completely off the rails with professional skincare terminology. For example, it might transcribe "Morning C, Night A" as "Morning C, Night Ten A," or "Niacinamide" as "Nian Xian An."
The workaround: Never manually edit the subtitles on the timeline! Before exporting, open the "Custom Dictionary" feature and batch-import 20 industry jargon terms like "Morning C Night A, Niacinamide, Retinol" in advance. The system will instantly perform a global replacement and recalibrate the timeline, solving a half-hour proofreading job in 1 second.
With the video edited, the soul of the short video—the copy—is still missing. Switch to the "Copy Generation" panel and select the "Xiaohongshu Viral Style." Based on the core selling point of each video, the AI will automatically extract 3 eye-catching titles and generate the body text.
Compared to the stiff "video content summaries" generated by other competitors, our generated copy naturally has that internet vibe: "Late-night face sagging? Saved! This Morning C Night A serum is literally a fountain of youth✨". It even sorts out the Emojis and Tags perfectly for you—just copy and post.
The final 5 exported videos are all in standard vertical 9:16 format. The first 3 seconds feature the host's most gripping pain-point hook (e.g., "How to save your sagging face after 25"), followed by dense product showcases and effect comparisons in the middle, and ending with dynamic text prompting viewers to follow. Paired with the freshly generated Xiaohongshu copy, a complete set of distribution materials is ready to go.
Here’s a "skincare/beauty livestream clipping" parameter template I use often. I recommend bookmarking it directly:
Will AI-edited videos suffer from severe homogenization?
By adjusting the weight parameters of "Semantic Highlight Extraction" and introducing multi-track random BGM and dynamic text templates, you can effectively break the homogenization and ensure each video has a unique visual rhythm.
What if the livestream replay has background noise or the background music is too loud?
After importing the footage, first enable the "Voice Enhancement and Background Audio Separation" feature. Lower the volume of the background audio track or mute it entirely to ensure the accuracy of AI speech recognition and subsequent subtitle generation.
Can the generated copy be published directly, or does it need manual polishing?
The AI-generated Xiaohongshu copy already boasts a high level of completion and internet appeal. I recommend spending just 1 minute scanning it and tweaking any catchphrases to better match your personal IP's tone, and it's ready to publish.
