Web Browser Support

Supported Browsers & Operating Systems

We officially support and test Sync Labs Studio on the latest versions of the following browsers and operating systems.

Web Browsers
  • Chrome
  • Firefox
  • Safari
  • Edge
Operating Systems
  • Windows
  • macOS
  • Android
  • iOS, iPadOS

While Sync Labs Studio might work on other browsers, operating systems, or older versions, they are not actively tested, and we cannot guarantee full functionality.

Browser Extensions Support

Certain browser extensions can interfere with how Sync Labs Studio functions. If you encounter unexpected behavior, please check whether any of the following extensions are active.

Problematic Extensions
Common Issues Caused
  • Seeing an “Unauthorized” error even when you’re logged in.
  • Missing model names in the Lipsync Settings pane.

If Studio says Download was blocked, select Download directly. If that fails, select Copy download link and open the link in a new tab. Allow downloads from sync.so in any extension that blocks them.

Output Video Playback

To ensure videos you generate with Sync Labs play back smoothly, it’s important that your web browser supports the necessary video and audio formats.

What to do if a video doesn’t play: If your browser cannot decode a completed output, select Download original and open the saved file in another video player. The generation completed successfully; you do not need to generate it again.

This guide explains our output formats and provides tools to test your browser.

Output Formats

Sync Labs-generated videos are encoded to ensure a balance of quality, file size, and broad compatibility.

TypeCodecDetails (MIME type)
VideoH.264 (AVC)avc1.64082a
AudioAACmp4a.40.2
ContainerMP4-

These formats are widely supported across modern web browsers.

1. Play a Sample Video

The simplest test is to play a sample video encoded with our standard settings. If the video plays correctly, your browser is likely compatible.

2. Check MIME Type Support

For a more technical confirmation, use these links to check for specific MIME type support. Your browser should show a green “supported” message for each.

Troubleshooting

If you encounter issues with studio or video playback or the compatibility tests fail in your web browser, follow these steps:

  1. Update Your Browser: Make sure you are using the latest version of your web browser.
  2. Use a Supported Browser: Ensure you are using one of the browsers officially supported by us, as listed at the top of this page.
  3. Disable Browser Extensions: Ad-blockers or privacy-focused extensions can cause issues. Try disabling them temporarily, or, use an Incognito or Private browser window (with extensions disabled).

Tip: Keeping your browser updated is the single most effective way to ensure compatibility with modern web standards and video formats.

If you continue to experience problems, please don’t hesitate to reach out to our support team.

Download all is unavailable

Project ZIP downloads require service worker support, which some private windows and in-app browsers lack. Open Studio in a regular supported browser window, or download results individually. See project downloads.

Preview plays without some audio

If Studio Pro says This browser can’t play some of the audio, the preview continues without that track. Your uploaded files stay unchanged. Try an updated supported browser. If the problem persists, convert the audio to AAC and upload it again. See media formats.
