How to Turn Long Videos Into Shorts, Reels and TikToks

One good long video can feed your short-form channels for a week. The hard part isn't the editing. It's watching an hour of footage to find the 60 seconds worth posting, then reframing and captioning each one. Here's the workflow, step by step.

Step 1: Find moments that stand on their own

A good clip makes sense to someone who never saw the full video. Look for:

• A strong first line. A bold claim, a question, a surprising number, or the middle of a story.
• One idea per clip. If you need to explain context first, it's the wrong moment.
• An ending that lands. A punchline, a lesson, a cliffhanger. Don't fade out mid-sentence.

Most solid clips run 30 to 90 seconds. Platforms allow longer now (YouTube Shorts and Instagram Reels both accept up to 3 minutes), but a tight clip that people rewatch usually beats a long one they leave.

Step 2: Reframe for a phone

Short-form is vertical: 9:16, 1080x1920. When you crop a widescreen video, keep the speaker's face in the frame for the whole clip, not just the first second. For slides, screen recordings or two people on screen, cropping tight cuts off what matters. Show the full frame centered over a blurred copy of itself instead, with the title above and captions below.

Step 3: Caption everything

A lot of people watch short videos with the sound off, so burned-in captions aren't optional. Make them big, high contrast, two lines at most, and keep them out of the bottom area where the platform puts its buttons and description. Highlighting the word being spoken helps people follow along.

Step 4: Give every clip its own title and caption

Each clip is its own post. Write a short on-screen title that tells people why to keep watching, a caption that adds one line of context, and a few relevant hashtags. Same voice as the rest of your brand.

Step 5: Post on a rhythm

Six clips from one video is about a week of posting at one a day. Spread them out rather than dumping all six at once, and post the strongest one first. Watch which openings hold people and use that style next time.

Doing it by hand vs. with AI

Whichever route you choose, you should always review clips before they go out. Automatic posting of AI-picked clips is how brands end up posting a moment out of context.

Watch out for export traps

Some editors let you do all the work, then put a watermark on the export or ask for a higher plan at the last step. Check before you start. We think you should always be able to download what you made, so BrandGoblin clips come out clean, no watermark, on every plan that can make them.

Try it on your next video

Video to Social takes a long video (up to 3 hours), finds about six strong moments, frames them vertically, adds captions in your brand's colors and fonts, and writes a title and post text for each. You approve what goes out. It's included with Creator Pro and Creator Max.
