How long can the source video be?

Recordings of up to roughly three hours are accepted, per Sparki's Long to Short page. The analysis runs across the entire timeline, which is exactly why whole-event recordings and full episodes work — the best minute is often nowhere near the start.

How many shorts come out of one long video?

A single session can yield a batch of ten to twenty clips, per the product's own page. The exact number depends on how much standalone material the recording actually contains — a dense two-hour interview gives up more than a sparse one, and nothing is padded to hit a count.

Can I paste a YouTube link instead of uploading a file?

Yes. A pasted YouTube URL is extracted and processed like an upload. Use it for your own channel's videos or content you are permitted to edit — the rights rules that apply to the source apply to the clips.

Will the clips come out vertical for Reels and Shorts?

Yes. The default output is a 9:16 vertical frame with the speaker kept in view, and lengths follow the destination's convention — around fifteen seconds for a Reel, up to sixty for a YouTube Short. Captions ride on each clip unless you say otherwise.

Can I change which moments Sparki picked?

That is the normal workflow. Describe the change — a stronger hook, less setup, more of the second speaker — and the selection is redone in chat without starting the cut over. Each clip also takes one-line fixes on its own, independent of the rest of the batch.

Long Video to Shorts Converter

A three-hour recording holds twenty clips and nobody has the week it takes to find them. Sparki sits through the whole thing, marks the stretches worth posting and hands back a batch of vertical, captioned shorts — then you steer the next round in chat.

How A Long Recording Becomes A Batch Of Shorts

The full video goes in; a set of platform-ready clips comes back.

Give It The Entire Recording

Podcasts, webinars, lectures, streams and vlogs all go in whole — recordings of roughly three hours are accepted, and a pasted YouTube link works in place of a file when the video is yours or cleared for use. Nothing needs pre-trimming: the point is to let the analysis run across the full timeline instead of guessing where the good parts are before you start.

Sparki Marks The Moments Worth Posting

The analysis reads narrative flow, emotional peaks, pacing and shot changes, then places edit markers on the stretches that can stand alone. From one long video you can take a batch of ten to twenty clips, each cut at sentence boundaries rather than mid-thought. Not happy with a pick? Describe what you wanted instead — a better hook, a shorter setup, more of the second guest — and the selection is redone through chat without rebuilding the cut.

Every Clip Lands Platform-Ready

Each selected moment is reframed to a vertical 9:16 canvas with the speaker kept in view, captioned, and trimmed to the length convention of where it is going — a fifteen-second Reel, a sixty-second YouTube Short. You receive a coherent set from one session, sized and styled per platform, instead of one clip that needs an hour of manual fitting.

Long-Form Sources Sparki Converts

Six kinds of long recording, each sliced the way its audience expects.

Podcast Episode Cuts

Two mics, three hours, twenty clips

Full interview and conversation episodes where the best minute is buried between wind-ups. Sparki finds the exchanges that work with no context, trims them at clean sentence edges and frames both speakers for vertical video. Feeding the main episode's best moments back into the feed as promotion.

Lecture & Webinar Snippets

One insight per short

Recorded courses, panels and conference talks that each cover far more than one post can hold. Sparki isolates single complete ideas — a definition, a framework, a surprising stat — so each snippet teaches one thing on its own. Turning teaching material into a discoverable short-form funnel.

Stream & Gaming Highlights

Hours of VOD, seconds of action

Long streams and session recordings where the clutch plays are scattered across the timeline. Sparki pulls the moments with real energy — the win, the fail, the reaction — and cuts each into a tight vertical clip with captions. Keeping a channel active between streams without re-watching VODs by hand.

Interview Soundbites

The quote, nothing around it

Expert interviews and panel recordings where one answer is the whole story. Sparki lifts the answer out complete — setup, point, payoff — so the short makes sense to someone who never saw the full conversation. Editorial accounts turning long conversations into quotable posts.

Product Demo & Webinar Recaps

Feature moments for the funnel

Recorded demos, launch streams and customer webinars recorded once for a live audience. Sparki excerpts the beats a buyer cares about — the problem, the reveal, the result — and formats each for the platform your funnel runs on. Sales and marketing teams extracting collateral from a single event recording.

Vlog & Day-in-the-Life Cuts

One outing, several posts

Long personal footage where the funny or striking beat only shows up once in twenty minutes. Sparki surfaces the beats with actual pull — the mishap, the view, the payoff — and crops each so the subject stays centred in vertical frame. Creators stretching one filming day across a week of posts.

Who Converts Long Videos To Shorts

One recording, a month of promotion

Slices a single webinar into teasers, quote cards and feature moments, each framed for the platform it is scheduled on. The event keeps producing leads long after the live audience went home.

Course creator selling enrolments

Extracts the single most useful idea from each module as a standalone short. Prospects get one genuine insight for free, then hit the enrolment link looking for the other forty.

Interview show editor

Ninety minutes in, three posts out
