How to turn a long video into YouTube Shorts
One hour of podcast, stream or webinar contains five to fifteen usable Shorts. Getting them out is a spec problem, an editing problem and a time problem, in that order. This guide covers all three: the exact technical requirements, the workflow that produces Shorts people finish watching, and what each way of doing it costs.
The specs that matter in 2026
| Setting | Value |
|---|---|
| Resolution | 1080 x 1920 (9:16 vertical) |
| Maximum length | 3 minutes |
| Container / codecs | MP4, H.264 video, AAC audio at 48 kHz |
| Frame rate | Match your source footage exactly |
| Safe zone for text and faces | Centered box, about 900 x 1160 px |
Any square or vertical video up to 3 minutes uploaded since October 15, 2024 is categorized as a Short (YouTube's own documentation). The 900 x 1160 safe zone is the conservative intersection of published recommendations: it keeps captions and faces clear of YouTube's buttons, title and progress bar on every screen size. Sources below.
Two practical notes. First, "up to 3 minutes" is a permission, not a target: the Shorts feed rewards completion rate, and most clips that travel still run under 60 seconds. Second, the safe zone is where most DIY Shorts quietly fail. Captions burned at the bottom edge of the frame end up under the progress bar and channel handle, and viewers cannot read them.
The 6-step workflow
- Find the moments before you cut anything. Scrub the full video and timestamp every self-contained moment: a claim, a story, a reaction, a number. A moment is usable only if it makes sense to someone who never saw the full video. If it needs context, the context has to fit inside the clip.
- Cut to one idea per Short. Trim each moment to its tightest version. Start half a second before the interesting thing, end the instant it lands. Every second that does not earn its place costs you completion rate.
- Reframe for vertical. A 16:9 frame cropped to 9:16 keeps less than a third of its width. The speaker's face or the action has to be re-centered shot by shot; a static center crop cuts off anyone who leans. This is the step auto-croppers most often get wrong.
- Burn in captions, inside the safe zone. Most Shorts are first watched on mute. Word-level captions with the current word highlighted are the retention standard now, placed in the center 900 x 1160 box, not at the bottom edge.
- Write the first second like a headline. The hook is not the intro of the original video, it is the most arresting sentence in the clip, moved to the front if necessary. Viewers decide in under two seconds.
- Export to spec and upload natively. MP4, H.264, AAC 48 kHz, source frame rate, 1080 x 1920. Upload through YouTube's own app or Studio so it is classified as a Short, and title it for search, not for the feed alone.
What each approach costs
| Approach | Cost | The catch |
|---|---|---|
| DIY (CapCut, Premiere, DaVinci Resolve) | $0 | Your time: plan on 1 to 3 hours per finished Short while learning, 20-40 minutes once fluent. |
| Self-serve AI clippers (OpusClip, Klap, vidyo) | $14-29 / month | They find and crop moments automatically, but you review, fix and export every clip yourself, and QC of the rendered output is on you. Entry plans cap upload minutes or watermark exports. |
| Freelance editor | $10-50 / Short | Real editorial judgment, inconsistent availability, and per-clip pricing adds up fast at volume. |
| Delivered AI service (Xtawiz) | $3 / cut, 4 for $10 | You send the long video and get publish-ready 9:16 cuts back: reframed, captioned in the safe zone, QC'd on the rendered frames. Disclosure: this is us. |

The math that decides for you
A weekly one-hour show yields roughly eight Shorts a month. DIY at 30 fluent minutes each is four hours a month, every month, forever. A $29/month tool cuts the labor but not the review-and-fix loop, and you are still the QC department. At $3 a delivered cut, the same eight Shorts cost $24 a month with zero hours, and the $10-for-4 bundle drops it to $20.
The right answer depends on what your hour is worth and whether you enjoy the edit. Many creators do, and for them DIY is genuinely free. For everyone else, the mechanical layer of Shorts production is a solved problem and should be priced like one.
Try it on your own footage for $0.01
Every workflow claim above is testable on a 30-second sample of your own video.
The Xtawiz pilot: send 30 seconds of any long video and $0.01 in escrow, and get it back as a vertical, captioned, safe-zone-correct cut, QC'd frame by frame. If it is not right, escrow refunds the dollar. If it is, you have your per-Short price and your four hours back.
