Start with the right dimensions and length for where your video will live

Instagram shows videos differently depending on whether you post to your feed, Stories, Reels, or as a carousel. Each format has its own ideal size and duration, and posting the wrong dimensions means Instagram will crop your video or add black bars around it.

Feed videos work best at a 1:1 ratio (square) or 4:5 (taller than wide). Stories are 9:16 (full-screen vertical). Reels are also 9:16 and can be up to 90 seconds long, though Instagram favors videos between 15 and 30 seconds. Carousel videos are 1:1 and limited to 15 seconds per clip. If you film on your phone in portrait mode, you're already close to the right shape for Stories and Reels — just check that nothing important gets cut off at the edges.

Before you edit, decide which format you're making for. That choice determines what you film, how you frame it, and what software you'll need. A video that works for Reels won't work for feed posts without resizing.

Key Takeaways

  • Instagram Reels (9:16 vertical, 15 to 90 seconds) reach more people than feed videos, so they're the best starting point if you're new to posting video.
  • Your phone's camera is good enough — you don't need external equipment to make videos that perform well on Instagram.
  • Editing software ranges from Instagram's built-in tools (free, limited) to CapCut (free, powerful) to Adobe Premiere Elements (paid, full-featured).
  • Text, music, and captions matter more than video quality on Instagram — people scroll fast, and these elements stop the scroll.
  • Post consistently to the same format so your audience knows what to expect and Instagram's algorithm learns what your account does.

Film on your phone using natural light and straightforward backgrounds

You don't need a camera, tripod, or lighting kit to make Instagram videos. Your phone's camera is designed for this — it's wide-angle, it focuses quickly, and it handles movement well. The main thing to control is light.

Film during the day near a window or outside. Avoid filming with the light behind you, because your face or subject will be dark. Position yourself so light comes from the side or front. If you're filming indoors at night, turn on overhead lights and any lamps nearby. Phone cameras struggle in dim light and will make your video grainy.

Keep your background straightforward. A plain wall, a bookshelf, or an outdoor setting all work. Busy backgrounds distract from what you're saying or doing. If you're filming yourself talking, position the phone at eye level or slightly above — this is more flattering than filming from below. Hold the phone steady by resting it against something or using a straightforward phone stand (these cost under $10).

Choose editing software that matches what you're making

Instagram's built-in editor (the one you see when you tap "Create" and select a video) is free and fast. It lets you trim, add music from Instagram's library, add text, and explore filters. Use this if you're posting a quick video with minimal editing — a clip of your product, a behind-the-scenes moment, or a straightforward talking-head video.

CapCut is free and works on both iPhone and Android. It's more powerful than Instagram's editor: you can layer multiple video clips, add transitions between them, adjust the speed of video, and use effects. CapCut also has a large music library and makes it straightforward to add captions automatically. Use CapCut if you're combining multiple clips into one video or want more control over timing and effects.

Adobe Premiere Elements costs around $100 per year and is the full-featured option. It handles longer projects, lets you work with multiple video and audio tracks, and gives you precise control over color and sound. Use this if you're making longer videos (over 2 minutes), editing multiple videos per week, or want professional-level color correction. For most Instagram creators starting out, CapCut is the right balance of power and simplicity.

Add text and captions so people watch without sound

Most people watch Instagram videos without sound — they're scrolling in public, at work, or with the sound off. If your video relies on audio alone, most viewers will skip it. Text and captions solve this.

Add a text overlay at the start that tells people what they're about to see: "How to make cold brew in 60 seconds" or "Watch this fail." This hooks people before they decide to keep watching. In CapCut, tap "Text" and choose a readable font — avoid thin or decorative fonts that are hard to read at small sizes on a phone.

Add captions for any dialogue or important sounds. CapCut can generate captions automatically if you tap "Captions" and let it transcribe your audio. Review the captions for accuracy — automatic transcription sometimes misses words or mishears accents. Captions also help people who are deaf or hard of hearing, which makes your video more useful to more people.

Keep text on screen long enough to read — at least 2 to 3 seconds for a short phrase. If you're moving text around the screen (like sliding it in from the side), make sure it doesn't cover the most important part of your video.

Use music and sound effects to hold attention

A video with no music or sound effects feels flat and slow, even if the visuals are good. Music and sound effects are cheap ways to make your video feel more polished and professional.

Instagram's music library (available in the built-in editor and in CapCut) has thousands of free songs sorted by mood and genre. Search for "upbeat" or "energetic" if you want something that moves fast, or "calm" if you're demonstrating something that takes focus. Most songs in these libraries are 30 seconds to 2 minutes long, which is perfect for Reels.

Sound effects add detail: the sound of a page turning, a camera shutter, a notification ping. These are available in CapCut's effects library. Use them sparingly — one or two per video is enough. Too many sound effects make the video feel chaotic.

Make sure the music doesn't drown out your voice if you're talking. In CapCut, you can adjust the volume of each audio track separately. Keep your voice at 100% and lower the music to 40 to 60% so people can hear both.

Edit for the scroll — keep cuts fast and hooks early

Instagram videos compete for attention in a feed where people are scrolling past dozens of videos per minute. Your first 3 seconds determine whether someone keeps watching or scrolls past.

Start with something that makes people stop: a surprising moment, a question, a bold visual change, or text that promises a payoff. "You've been doing this wrong" or "This takes 30 seconds" works better than "Today I'm going to show you." If you're making a tutorial or how-to, show the finished result first, then explain how to get there.

Keep cuts between clips quick — 0.5 to 1 second is good. Longer clips (5+ seconds of the same shot) feel slow on Instagram. If you're talking to the camera, cut to a new angle or a close-up of what you're demonstrating every 10 to 15 seconds.

Use transitions between clips, but don't overdo them. A straightforward cut (no transition) is fine. If you use a transition, keep it the same throughout the video — switching between different transitions makes the video feel disjointed. CapCut's "zoom" or "fade" transitions are subtle and professional.

Post consistently and track what works

Instagram's algorithm favors accounts that post regularly. If you post one video this week and nothing for a month, the algorithm won't know what your account is about and won't show your videos to many people. Pick a schedule you can stick to — once a week, twice a week, or daily — and post at the same time each day if possible.

After you post, check the insights (tap the video after 24 hours and scroll down to see how many people watched it, where they came from, and whether they saved or shared it). Videos that get saved or shared perform better than videos that just get likes. If a certain type of video (tutorials, behind-the-scenes, product demos) consistently gets more saves, make more of that type.

Reels reach more people than feed videos, so if you're trying to grow, focus on Reels first. Once you have a consistent audience, you can experiment with Stories and carousel videos.

Frequently Asked Questions

Do I need a ring light or external microphone?

No. Natural light from a window works fine for most videos. If you're filming at night, turn on overhead lights and lamps. For audio, your phone's built-in microphone is good enough if you're filming close to the camera. If you're filming from far away or in a noisy space, an external microphone (around $30) helps, but it's not necessary to start.

What's the difference between Reels and feed videos?

Reels are full-screen vertical videos (9:16) that Instagram promotes heavily in the Explore page and on followers' feeds. Feed videos are smaller and appear in the main feed alongside photos. Reels get more views because Instagram prioritizes them. Both use the same editing process — the difference is the dimensions and where you post.

Can I edit a video on my phone or do I need a computer?

You can edit entirely on your phone. CapCut and Instagram's built-in editor both work on mobile. If you're making longer or more complex videos, a computer gives you more screen space and faster processing, but it's not required.

How long should my Instagram video be?

For Reels, 15 to 30 seconds performs best, though Instagram allows up to 90 seconds. For feed videos, 15 to 60 seconds works. Shorter videos (under 30 seconds) get more complete views because people are more likely to watch all the way through. If you have more to say, break it into a series of videos instead of one long one.

What if my video doesn't get many views?

Check whether you're posting Reels or feed videos — Reels reach more people. Make sure your first 3 seconds hook the viewer with text, a surprising moment, or a question. Add captions so people can watch without sound. Post consistently so Instagram learns what your account does. It usually takes 5 to 10 videos before you see growth, so don't judge a single video too harshly.
