Smart Shorts

YouTube Shorts maker: turn any long video into Shorts that get watched

Your long-form videos are already full of Shorts. Splicora finds them, cuts them to 9:16 with captions, lets you tweak the first frame and the title, and publishes them to YouTube on a schedule — without opening a video editor.

Splicora — Smart Shorts

What you get

YouTube Shorts Maker, in practice

Right length, right shape

Shorts are trimmed to the under-60-second range that YouTube rewards, cropped to 9:16 with the speaker tracked in frame.

Captions people can read on mute

Word-accurate animated subtitles in any of 100 styles, burned in, so the Short works with the sound off.

Publish natively to YouTube

Connect your channel once. Schedule Shorts from the calendar with a title and description and Splicora posts them for you.

One video, every platform

The same clip is one click from TikTok, Reels and Bluesky, with per-platform captions and hashtags.

How it works

From upload to published in 4 steps

1

Paste the YouTube link

Or upload the raw recording before it is even on YouTube. Splicora fetches the transcript and analyses the whole video.

2

Choose from the suggested Shorts

Each candidate shows a start time, a preview and a virality score. Keep the ones you like or run Auto-Generate for a batch.

3

Polish the first two seconds

Add a hook line, pick a caption preset, choose the thumbnail frame. That is where a Short is won or lost.

4

Schedule to your channel

Set a date and time, write the title, and Splicora publishes the Short to YouTube — and to TikTok and Reels if you want.

Why Shorts deserve their own workflow

YouTube Shorts are not just "a TikTok on YouTube". They sit next to your long-form videos, they feed the same channel, and a good Short sends viewers back to the full upload it came from. That makes them the cheapest subscriber growth most channels will ever get: the footage already exists, and the algorithm is actively looking for vertical content to recommend.

The blocker is production. Cutting a 20-minute video into six Shorts by hand — finding the moment, cropping to vertical, captioning, exporting, uploading, titling — takes most creators longer than the original edit. Splicora collapses that to a few minutes, and the AI clip generator does the finding.

What makes a Short perform

Splicora is opinionated about this, because the data is fairly clear:

  • A hook in the first two seconds. The hook generator writes a 3–5 second opener from your own best line and voices it with a free AI voice.
  • Captions, always. A large share of Shorts views happen with the sound off; the subtitle generator makes them readable and on-brand.
  • A single idea. Shorts that try to summarise the whole video lose; Shorts that make one point and stop win. The clip scoring favours completeness for exactly this reason.
  • A clean vertical frame. AI Reframe tracks the face so the speaker is never half out of shot after the crop.
  • A title that reads like a search. Splicora drafts titles and descriptions per platform; you edit the words, not the format.

From one long video to a Shorts schedule

A typical week looks like this: upload Monday's long video, accept six suggested Shorts, tweak two of them in the editor, and schedule one per day through the content calendar. The Shorts go out with their own titles, the long-form link in the description, and the same clips cross-posted to TikTok and Instagram with platform-specific captions. That is a week of daily posting from one afternoon of work.

If your channel is faceless, the faceless video generator produces Shorts from a script and a voice instead of a recording.

Frequently overlooked details Splicora handles

  • Music: the built-in library is royalty-free, so a Short never gets muted for copyright.
  • Audio: the audio enhancer removes room noise before captions are generated, which also makes the captions more accurate.
  • Thumbnails: pick any frame and apply a style preset from the thumbnail generator — Shorts show a thumbnail in the channel tab even when the feed does not.
  • Watermarks: paid plans export clean; the Free plan adds a small watermark.

FAQ

Questions people ask

Yes. Connect your YouTube account under Connections and schedule Shorts from the calendar. Splicora publishes them at the chosen time with the title and description you set.

Yes, by default. You can choose from 100 animated caption styles (20 on the free plan), position them anywhere on screen, or turn them off for a specific clip.
