How to Automatically Cut Long Videos into Shorts

Cutting Shorts by hand means hours of scrubbing through a timeline to find a handful of good moments. AI does the same job in minutes: it finds the most gripping moments in a long video, crops them to vertical format, and adds subtitles. Let's break down how automatic Shorts cutting works, what OpusClip and similar tools can do, and how to turn one video into a stream of short clips that bring in subscribers.

Why you need Shorts cutting

Shorts solve two problems. The first is repurposing: one long video turns into a dozen pieces of content without any new production. You've already invested in the script, voice-over, and visuals — it makes sense to squeeze the most out of that. The second is the funnel: short videos cheaply reach cold audiences and lead them toward your long-form content and a subscription.

Manual cutting doesn't scale: the more long videos you publish, the more the process chokes. Automatic Shorts cutting removes this bottleneck — producing short videos stops depending on how much time you can spend editing.

How automatic Shorts cutting works

Tools like OpusClip analyze a long video across several layers and assemble vertical clips on their own:

1. Transcription. First, speech is converted into text with timestamps — the whole analysis is built on top of this.
2. Finding gripping moments. The AI looks for self-contained, meaningful segments — strong ideas, hooks, punchlines — not random chunks.
3. Virality score. Each segment gets a score predicting how likely the clip is to take off. This helps you pick the best ones instead of cutting everything indiscriminately.
4. Vertical cropping. The clip is converted to 9:16 format, with auto-tracking keeping the speaker or key subject centered in frame.
5. Subtitles and styling. Dynamic subtitles are added automatically (a large share of Shorts are watched without sound), along with titles if you want them.

The result: publish-ready vertical clips that just need a quick review and touch-up.

OpusClip and alternatives: what to choose

OpusClip is one of the best-known tools built specifically for cutting long videos into Shorts, with a virality score and auto-generated subtitles. But it's not the only option:

• OpusClip — focused on finding "viral" segments and clean subtitles; a solid choice as a primary cutting tool.
• Other clip tools — many video editors and AI services have added similar auto-cutting and vertical-cropping features.
• Built-in platform tools — sometimes your regular editor's tools are enough if the volume is small.

The right choice depends on your volume and language: check the quality of Russian speech recognition and subtitle accuracy on your own material — that's where these services differ the most.

How to make Shorts that actually work

Automation finds the segments, but watch-through rate for a short video still comes down to the same principles as long-form content:

• A strong hook in the first second. Shorts don't have time to build up — the gripping line or shot needs to be right at the start. Choose clips that open with a hook.
• A complete idea. A good Short is a micro-story with a beginning and a payoff, not a random fragment. The score helps, but the final call is yours.
• Large, centered subtitles. They're read without sound; make sure the text doesn't cover faces or run off the edge.
• A vertical frame with no awkward cuts. Make sure auto-tracking hasn't cropped out anything important — adjust the framing if needed.
• A call to the long-form video. A Short is an entry point into the funnel; guide viewers toward the full video and a subscription.

How to build Shorts into your channel's funnel

Cutting isn't the end goal — it's part of a system. Here's the logic that works:

• One long video → a batch of Shorts. Pull several of the best segments from each video and publish them on a schedule, spreading reach out over time.
• Shorts warm up cold audiences. They generate views more cheaply and introduce new viewers to your channel.
• Flow into long-form content. Reference the full video — in the description and in the clip itself — where the topic is covered in depth.
• A steady stream. Regular Shorts keep your channel active between long-video releases.

This is how repurposing and the funnel come together: instead of producing short videos from scratch, you systematically repackage content you've already made.

Common mistakes

• Publishing everything. Even with a virality score, review your clips — weak segments drag the channel down.
• A fragment instead of an idea. A clip without a beginning and payoff won't get watched through. Use complete segments.
• A weak opening. If there's no hook in the first second, the Short will flop. Cut around the hook.
• Sloppy cropping. Check that auto-tracking hasn't cut off a face or key subject.
• No link to the long-form video. Without a call to action, the funnel doesn't work — Shorts live on their own and don't generate subscriptions.

How many Shorts to make and how to publish them

Automation generates plenty of clips, but dumping them all at once isn't the way to go — Shorts work best as a system:

• A few of the best from each video. Instead of every segment, take the strongest ones by meaning and virality score.
• Scheduled publishing. Spread clips out over time to keep the channel active between long-video releases.
• Consistency over volume. A steady stream of short videos warms up your audience better than a one-time burst followed by silence.
• A link to long-form content. Every Short should lead to the full video and a subscription — without that call to action, the funnel doesn't close.

This way, one video delivers both reach through short clips and a flow of viewers into your long-form content — without new production and with almost no extra time invested.

How Goutub speeds this up

Goutub handles Shorts cutting natively — it's a built-in step in the pipeline, not a separate service where you have to upload a finished video and wait. As soon as the long video is assembled, the system automatically finds the gripping moments, crops them to vertical, adds subtitles, and prepares a batch of Shorts ready to publish. You don't need to move the file to OpusClip, download the clips, and adjust them by hand — one video instantly turns into a stream of short clips for your funnel, and this scales across your entire channel.
