❓ Frequently Asked Questions

Getting Started

Q: Do I need technical knowledge to use VideoGrab? A: No technical knowledge is required. VideoGrab automatically detects videos and provides one-click downloads. The interface is designed to be intuitive for users of all technical levels.

Q: Will VideoGrab work on all websites? A: VideoGrab works on most websites that use standard video embedding methods. However, it cannot download from YouTube, TikTok, Instagram, VK, or Dailymotion due to their terms of service. It also cannot access DRM-protected content from streaming services like Netflix or Disney+.

Q: Can I use VideoGrab on mobile devices? A: VideoGrab is designed for desktop Chrome browsers. While Chrome extensions can work on some mobile browsers, the experience is optimized for desktop use with full keyboard and mouse interaction.

Video Detection & Downloads

Q: Why doesn’t VideoGrab detect videos on some pages? A: Several factors can affect detection:

• Videos may load dynamically after page interaction
• Some sites use proprietary or complex video players
• The video might be in a format not supported by the free version
• The website might be using DRM protection
• Videos might be embedded in iframes with restricted access

Q: What’s the difference between free and premium versions? A: The free version supports standard formats (MP4, WebM, MOV, etc.) and basic features. VideoGrab Ultimate (premium) adds:

• Advanced streaming formats (M3U8, M4S)
• Enhanced detection algorithms
• Batch download capabilities
• Format conversion tools
• Priority technical support

Q: How large can downloaded videos be? A: There’s no specific size limit imposed by VideoGrab, but very large files (>1GB) may be affected by:

• Browser memory limitations
• Network stability
• Available disk space
• Chrome’s download timeout settings

Q: Can I download audio-only files? A: Yes, VideoGrab supports audio formats including MP3 and AAC. It can detect and download audio files embedded in web pages.

Video Library Management

Q: Where are my downloaded videos stored? A: Videos are downloaded to your browser’s default download location (usually the Downloads folder). The VideoGrab library creates references to these files but doesn’t move them. You can change your download location in Chrome settings.

Q: How many videos can I store in my library? A: The library can handle thousands of video references. The actual limit depends on your browser’s storage capacity and available disk space for the video files themselves.

Q: Can I backup my video library? A: Currently, the library stores references to downloaded files. If you move or delete the actual video files, the library references will be broken. We recommend keeping downloaded videos in a consistent location and backing up both the files and your browser data.

Q: Can I share my video library with others? A: The library is stored locally in your browser. While you can share individual video files, there’s no built-in sharing feature for the entire library organization. This is planned for future updates.

Technical Questions

Q: Does VideoGrab send my data to external servers? A: No, VideoGrab processes everything locally in your browser. Video detection, downloads, and library management all happen on your device. No video content or personal data is transmitted to external servers.

Q: Why does VideoGrab need so many permissions? A: VideoGrab requires specific permissions for its functionality:

• Access to all websites: To detect videos across the web
• Downloads permission: To save videos to your device
• Storage permission: For the video library functionality
• Side panel permission: For the persistent interface feature

Q: Can VideoGrab slow down my browser? A: VideoGrab is designed to be lightweight, but continuous video detection does use some resources. You can optimize performance by:

• Adjusting detection frequency in settings
• Closing unused tabs
• Disabling features you don’t use
• Keeping your browser updated

Q: Is VideoGrab compatible with other extensions? A: VideoGrab is generally compatible with most extensions, but conflicts can occur with:

• Other video downloaders
• Aggressive ad blockers
• Privacy extensions that block content scripts
• Download managers that intercept downloads

Legal & Ethical Questions

Q: Is it legal to download videos from websites? A: The legality depends on several factors:

• The website’s terms of service
• Copyright status of the content
• Your intended use of the downloaded content
• Local laws in your jurisdiction

VideoGrab includes a rights confirmation dialog to remind users about copyright considerations. Always ensure you have the right to download and use the content.

Q: Why can’t I download from YouTube and similar platforms? A: VideoGrab intentionally blocks downloads from major platforms because:

• These platforms explicitly prohibit downloading in their terms of service
• They have specific monetization models that downloading would circumvent
• They offer official offline viewing options (like YouTube Premium)
• We respect content creators’ rights on these platforms

Q: How does VideoGrab handle copyright protection? A: VideoGrab includes several copyright protection measures:

• Rights confirmation dialog before each download
• Blocking of major platforms with clear anti-downloading policies
• Educational information about copyright in the extension
• Encouragement to only download content for personal, non-commercial use
