App Preview Video Guide — How to Make App Store & Google Play Videos That Convert
WhixFrame Team
App marketing tools built by developers who've shipped 20+ apps to the App Store and Google Play.
App preview videos are one of the highest-leverage but most underutilized elements of an app store listing. In our analysis, apps that add a preview video see conversion rate lifts of 20–35% — making it one of the best ROI investments in your entire marketing stack.
This guide covers every technical requirement, plus a production framework that works even if you have never edited a video in your life.
Why App Preview Videos Matter
Screenshots are static. They show a moment — but they cannot show how the app feels to use, how fast it is, or how seamlessly a flow works. A 15-second preview video shows all of that.
More importantly: video autoplays in search results on iOS. When a user searches for an app in your category, your video plays silently before they even tap into your listing. This is the highest-impact impression you get — and it happens without the user taking any additional action.
Why do so few apps have them? Most developers assume they need a professional video editor or motion designer. They don't. We'll show you how to create a high-converting preview video without either.
iOS App Preview Video Specs (2026)
| Spec | Requirement | Notes |
|---|---|---|
| Duration | 15–30 seconds | Under 15s is too short; over 30s will be rejected |
| Format | H.264 or HEVC (.mov or .m4v) | MP4 is not accepted — must be .mov or .m4v |
| Resolution | Match screenshot resolution | E.g., 886 × 1920 for iPhone 16 Pro Max portrait |
| Frame rate | 30fps minimum | 60fps is supported and recommended for smooth UI |
| Max file size | 500 MB | Aim for under 200 MB in practice |
| Orientation | Portrait or landscape (not mixed) | Must match your screenshots' orientation |
| Captions/subtitles | Optional but recommended | Video autoplays muted — text overlays critical |
| Count | Up to 3 videos per device class | First video plays automatically in search results |
⚠️ Common rejection: Uploading an .mp4 file instead of .mov or .m4v. Apple will reject immediately. Convert your file before upload: on Mac, use QuickTime > File > Export As. On Windows, use HandBrake with the .m4v container.
Google Play Preview Video Specs (2026)
Google Play uses a different system — you provide a YouTube URL rather than uploading a video file directly. This means your preview video must be a public or unlisted YouTube video.
| Spec | Requirement |
|---|---|
| Source | YouTube URL (public or unlisted) |
| Duration | 30 seconds – 2 minutes (recommended: under 60 seconds) |
| Resolution | 1920 × 1080 minimum (landscape preferred) |
| Orientation | Landscape (16:9) strongly preferred by Google |
| Content | Must show real app UI — no people, no external footage |
| Age restriction | Must match your app's content rating |
Google Play vs. App Store video strategy: For iOS, create a tightly edited 15–20 second portrait video. For Google Play, you can use the same video (converted to landscape, or create a separate cut) uploaded to YouTube. Many developers repurpose their App Store preview as a Google Play promo video with minor edits.
The First-3-Second Rule
In user testing studies across multiple platforms, users decide whether to keep watching a video or scroll past within the first 2–3 seconds. This is true for ads, for YouTube, and for app preview videos.
What this means practically:
✓ Do this in the first 3 seconds:
- Show the most impressive thing your app does
- Display your key benefit as on-screen text
- Start mid-action — not from a loading screen or empty state
✗ Never start with:
- A logo animation or app name reveal
- An empty state / onboarding screen
- A "coming soon" or feature list slide
- Ambient background footage with no UI shown
Script Structure: What to Show and When
For a 20-second iOS preview video, this structure works across most app categories:
| Timestamp | Content | Goal |
|---|---|---|
| 0:00 – 0:03 | Hero moment: show the app's #1 feature in action | Hook — stop the scroll |
| 0:03 – 0:08 | Feature 1 in use, with text overlay explaining the benefit | Value delivery |
| 0:08 – 0:13 | Feature 2 or a different use case, with text overlay | Depth and versatility |
| 0:13 – 0:17 | Social proof or stats ("10,000+ daily users") | Trust signal |
| 0:17 – 0:20 | CTA screen: app name + download prompt | Convert |
Production Tips (No Video Editor Required)
You do not need Final Cut Pro or Adobe Premiere to create a high-converting preview video. Here is the zero-budget stack:
- Screen recording: Use iPhone's built-in screen recorder (Control Center > Screen Recording). Record at 60fps for smooth UI animations. Record 3–4 takes of each flow and keep the best.
- Editing on Mac (free): iMovie handles basic trimming, transitions, and text overlays. Export as .mov at 1080p or higher.
- Editing on PC (free): DaVinci Resolve is professional-grade and completely free. Steeper learning curve but unmatched quality.
- AI-powered option: WhixFrame's App Preview Animator takes your static screenshots, adds text layers, transitions, and motion effects, and exports a preview-ready .mov file — no video editing required.
Why You Need Subtitles (Autoplay is Muted)
Both App Store and Google Play autoplay preview videos with the sound muted by default. This means your video needs to communicate its entire message visually — no narration, no background music that conveys meaning.
Every key benefit must appear as large, readable on-screen text. Design your text overlays to be readable at the same 200px-wide size your screenshots appear at in search results.
Text guideline: Minimum 30pt font at 1080p resolution. Bold weight. High contrast against the UI background. 5 words maximum per text overlay.
Creating Preview Videos With WhixFrame
WhixFrame's App Preview Animator was built for exactly this use case: turning your existing screenshots into animated, store-ready preview videos without a video editor.
The workflow:
- Upload your 3–5 best screenshots to the Animator
- Add text overlays for each screenshot (benefit-led, 5 words max)
- Select a transition style (slide, fade, zoom, parallax)
- Choose animation timing — WhixFrame pre-sets the per-slide duration to hit the "hook in 3 seconds" rule automatically
- Export as .mov (iOS-ready) or .mp4 (YouTube/Google Play-ready)
Common Preview Video Mistakes
Starting with a logo/intro animation
You have 3 seconds to hook the viewer. A logo animation wastes all of them.
Recording at 30fps on a slow device
Laggy UI in a preview video is the #1 conversion killer. Record on your fastest device, or use the Simulator on Mac.
Uploading .mp4 to App Store Connect
Apple only accepts .mov and .m4v. Uploading .mp4 is an instant rejection.
No text overlays
Video is muted by default. Without text, your video communicates nothing in search results.
Showing every feature in 15 seconds
Cramming too much creates a frenetic, confusing experience. Pick 2–3 moments, show them clearly.
Using stock footage or lifestyle shots
App Store guidelines require that preview videos show the actual app UI. Stock footage can result in rejection.
Create an App Preview Video in Minutes
Upload your screenshots, add text layers, pick a transition style, and export a store-ready .mov file. No video editor needed.
