Transcript & footage credit
“The universe was behaving much more strangely than we imagined. And that instead of coasting out at the constant speed forever or slowing down, it in fact is accelerating. Huge, unexpected mystery.”

From a YouTube link to a finished vertical clip.
- Import your source. Paste an accessible YouTube URL or upload your original video. Use material you own or have permission to repurpose.
- Choose the edit. Let AI prepare a short, or select the passage manually. Choose your vertical destination and a frame that keeps the important content visible.
- Review the output. Open the completed render in My Shorts. Check captions and camera cuts, then download the video for publishing.
If a link cannot be imported, use your original file. For tutorials with slides or screen demonstrations, Fit preserves the full scene. Visual person tracking does not determine who is speaking from audio, so always review multi-person footage.
Turn my video into a ShortWhere it fits
Every upload feeds your Shorts shelf
Publish your main video, paste its link into ViralCut, and ship three or four Shorts from it over the following days — each one pointing new viewers back to the full video.
Course makers repurposing lessons
Pull the sharpest 40 seconds from a lesson or webinar as a vertical clip. It works as a free-sample ad for the paid content, with captions doing the heavy lifting on mute.
Testing hooks before committing
The AI scores every candidate moment and shows the transcript quote behind it. Post the top two as Shorts, see which retains, and learn what your audience actually stops for.
FAQ
Converting long-form into Shorts, answered.
How do I convert a YouTube video into Shorts?
Paste the video URL into ViralCut Pro. The AI analyzes the full video, surfaces the most watchable moments with virality scores and reasoning, and exports them as vertical 9:16 clips with captions — ready to upload as Shorts, TikToks, or Reels.
Will a 16:9 video look right as a vertical short?
Yes. The smart crop converts 16:9 to 9:16 per scene and tracks the people on screen, so the frame follows the subject through cuts instead of blindly cropping the center of the widescreen shot.
Can I edit what the AI picks?
Yes. Choose manual editing to select and trim moments and set caption styles before rendering. AI creation queues a prepared edit automatically, which you can review and reopen from My Shorts. Tracking and final caption text are generated during rendering; the source preview is not the finished result.
Does this work for course videos and webinars too?
You can use talking-video lessons, interviews and webinars you have permission to repurpose. Check that a selected moment makes sense on its own. Use Fit for slides or screen recordings when a narrow crop would hide essential information. Results depend on the source footage.
