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 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: Higher-quality models generally produce higher-resolution output. Check the model-specific details in the video Studio for the exact specifications of the currently selected model.

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:
This approach serves WebM to browsers that support it (most modern browsers) and falls back to MP4 for others.

​
File size considerations

AI-generated video files are typically modest in size due to their short duration (2–10 seconds). Approximate file sizes: Actual sizes vary significantly by resolution, motion complexity, and model output settings.

​
Downloading your video

To download a generated video:
  1. Locate the video in the Studio gallery
  2. Click the download icon on the video
  3. Select your preferred format from the dropdown (MP4, WebM, or MOV)
  4. 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.
