Frequently Asked Questions

What is the quality of captured thumbnail images?
Thumbnail image quality depends on selected output format and quality settings. If selecting high quality settings, can maintain video original quality; if selecting lower quality settings, may reduce image quality to reduce file size. We recommend using high quality settings for best results. Original size mode will maintain video original resolution, suitable for high quality uses.
Will my video file be uploaded to the server?
No, all processing is done in your browser. Your video file never leaves your device, completely protecting your privacy.
How large video files can I capture?
