Turn one long YouTube video into clips that pop.

Which Moments Make a Good Short

This YouTube Shorts maker does not invent footage. It cuts clips out of a long video you already made, so the whole job comes down to picking the right moments. A good Short makes sense with no context, lands its point fast and gives someone who has never seen your channel a reason to keep watching past the first few seconds.

Here is how the tool reads your video. It transcribes the audio, works out the main topic and who it is for, then proposes five candidate clips and scores each one on how strong its opening is. It favors moments where you make a bold or counterintuitive claim, reveal something unexpected, ask a question that demands an answer, or state a striking fact. It avoids starting a clip on a passage where the speech was hard to make out.

The spacing rule matters: three clips from the same minute would feel like one idea told three times. Each clip in the results shows its title, hook score and the reason it was picked, so you can judge it before posting.

9:16 Framing: How the Crop Is Chosen

Most long videos are landscape, and a Short needs to be vertical. Rather than a single blind 9:16 video converter setting, you choose one of three layouts before the clips are rendered:

Blur Background is the safe default: nothing gets cut off, and captions sit in the blurred area under the picture. With Center Crop or Large Main you decide where the crop sits. Leave it on Manual and use the slider, or try one of two beta options: Auto-track face finds the speaker in each clip and centers them, which suits single-speaker videos, and Active speaker pans between people as they talk, which suits two-person interviews. With a landscape source, the third clip uses a split screen: the main picture on top and the lower right corner of the frame, where a face cam usually sits, underneath.

Shorts Length, Captions and Hook Timing

Since October 15, 2024, YouTube counts square or vertical uploads of up to three minutes as Shorts. Wider formats such as 16:9 stay regular videos whatever their length. Source: YouTube Help, Shorts length.

Staying well under the limit is deliberate. A clip that shows one moment tends to hold attention better than one that wanders, and it leaves room to post the same cut on Reels or TikTok. The hook score is judged on the first three seconds of each clip, because that is where a scrolling viewer decides. Captions are burned into each clip in the style you pick, or you can switch them off, and they carry the hook for anyone watching with the sound muted. If you want a different caption look on a full-length video, the Caption Maker offers the same kind of presets for horizontal uploads.

Repurpose One Long Video Into a Week of Shorts

One run turns a long video into three Shorts, which is a simple way to repurpose video into shorts without re-editing. The source can be an upload of up to 60 minutes and 1 GB, or a public or unlisted YouTube link, including one picked from your channel's videos. A 30-minute interview or tutorial usually holds more than three good moments, so trim a different section and run it again until you have a clip for each day you plan to post that week.

Each clip needs its own packaging. Write a title that states the payoff rather than reusing the long video's title; the AI title generator can help with options. The long video they point back to still needs a strong cover from the Thumbnail Maker. When a channel is connected, you can upload finished clips straight to YouTube. They go up as private by default, so you can review them and set the visibility yourself before anyone sees them.
