ZeroTwo generates video in three formats: MP4, WebM, and MOV. This page explains the differences and helps you choose the right format for your use case.
Format comparison
| Format | Codec | Best for | Compatibility |
|---|
| MP4 | H.264 | Universal sharing, social media, web, email | Near-universal — works on virtually all devices, browsers, and platforms |
| WebM | VP9 | Web embedding, smaller file sizes, browser-based playback | Modern browsers; limited native support on older desktop apps |
| MOV | QuickTime | Mac workflows, professional video editing, iOS ecosystem | Native on Mac and iOS; requires QuickTime or codec install on Windows |
Format details
MP4 (H.264)
MP4 with H.264 encoding is the most widely supported video format available. It plays natively on:
- All major browsers (Chrome, Firefox, Safari, Edge)
- Windows, macOS, Linux, iOS, Android
- Social media platforms (YouTube, Instagram, TikTok, X, LinkedIn)
- Video editing software (Premiere, DaVinci Resolve, Final Cut Pro)
- Most messaging apps and email clients
Recommended for: any use case where you want maximum compatibility — sharing, posting to social media, embedding on a website, sending to someone else.
WebM (VP9)
WebM is an open format developed for web use. It offers good quality at smaller file sizes compared to MP4, and plays natively in all modern web browsers.
Advantages: smaller file size, open standard, good for streaming.
Limitations: less native support in desktop video applications, not ideal for social media uploads or sharing with people who may use older software.
Recommended for: embedding video directly on a web page, browser-based projects, situations where file size matters.
MOV (QuickTime)
MOV is Apple’s native video container format. It’s the standard format for professional video workflows on Mac and is natively supported across the Apple ecosystem.
Advantages: excellent quality, native integration with Final Cut Pro and other Apple tools, lossless or high-bitrate encoding options.
Limitations: requires QuickTime or compatible codec on Windows; larger file sizes; not optimal for web upload.
Recommended for: Mac-based video editing workflows, Final Cut Pro projects, iOS delivery, professional production pipelines.
Choosing the right format
Start with MP4 unless you have a specific reason to use another format. MP4 (H.264) is the safest choice for any situation where you don’t control the viewer’s environment.
Use WebM if you’re embedding video on a website you control and want a smaller file size.
Use MOV if you’re working in Final Cut Pro, importing into a Mac-based professional editing workflow, or delivering to an Apple ecosystem context.
Technical specifications
Output specifications depend on the video generation model selected. Typical ranges:
| Property | Typical range |
|---|
| Resolution | 512×512 to 1920×1080 (model-dependent) |
| Frame rate | 24–30 fps (model-dependent) |
| Duration | 2–10 seconds per clip (model-dependent) |
| Aspect ratio | 16:9, 9:16, or 1:1 |
Using generated videos in different contexts
Social media
| Platform | Recommended format | Notes |
|---|
| YouTube | MP4 | Universal, works on all devices |
| Instagram | MP4 | Reels, Stories, Feed — MP4 is the standard |
| TikTok | MP4 | Standard upload format |
| X (Twitter) | MP4 | MP4 up to 512MB |
| LinkedIn | MP4 | Recommended for all video content |
Video editing workflows
| Software | Recommended format |
|---|
| Final Cut Pro | MOV (native support) |
| DaVinci Resolve | MP4 or MOV |
| Adobe Premiere | MP4 or MOV |
| CapCut | MP4 |
| iMovie | MOV or MP4 |
Web embedding
For embedding video on a website via an <video> HTML tag, WebM provides the best size-to-quality ratio in modern browsers. For maximum browser compatibility, provide both MP4 and WebM sources:
<video controls>
<source src="video.webm" type="video/webm">
<source src="video.mp4" type="video/mp4">
</video>
File size considerations
AI-generated video files are typically modest in size due to their short duration (2–10 seconds). Approximate file sizes:
| Format | Typical size (5-second clip, 1080p) |
|---|
| MP4 (H.264) | 5–20 MB |
| WebM (VP9) | 3–15 MB |
| MOV (QuickTime) | 10–40 MB |
Downloading your video
To download a generated video:
- Locate the video in the Studio gallery
- Click the download icon on the video
- Select your preferred format from the dropdown (MP4, WebM, or MOV)
- The file downloads to your device’s default download location
If you’re unsure which format to choose, download MP4. It works everywhere and is the safest choice for sharing, editing, or uploading to any platform.
