Frequently Asked Questions
- Is Video Studio completely free?
- Yes, 100% free. No account required, no watermarks, no file limits.
- Are my videos uploaded to a server?
- No. All processing runs locally in your browser using ffmpeg.wasm — a WebAssembly port of ffmpeg. Your video data never leaves your device.
- Why does it take a moment to start the first time?
- The tool downloads the ffmpeg WebAssembly engine (~30 MB) on first use. After that it is cached in your browser and subsequent uses start instantly.
- What video formats are supported?
- You can upload MP4, MOV, AVI, WebM, MKV, and M4V files. Output formats vary by operation: compress to MP4/WebM, convert to MP4/WebM/MOV/AVI/MKV/GIF, extract audio as MP3/WAV/AAC/OGG.
- What is the maximum video file size?
- Up to 500 MB. Larger files may use more browser memory — for very large files, a 64-bit browser with at least 4 GB RAM is recommended.
- How do I trim a video to a specific time range?
- Select the Trim tab, enter your start and end time in HH:MM:SS format or as plain seconds, then click Process Video. The tool uses stream copy for MP4 so there is no quality loss.
- How does the Extract Frames feature work?
- Choose to capture frames every N seconds or at specific timestamps (comma-separated). The tool exports each frame as a PNG image and bundles them into a ZIP file for download.
- Does it work on mobile?
- Yes, Video Studio works on all modern browsers including mobile Chrome and Safari. Performance depends on your device — desktop or laptop is recommended for large files.
