Video frame extractor FAQ
Clear answers about compatibility, frame quality, privacy, and batch downloads.
Does VixFrame upload my video?
No. Your video file, decoded frames, and captures stay in the current browser tab. VixFrame does not receive the video content.
Does extracting a frame reduce image quality?
VixFrame draws the decoded frame at the video's original width and height, then exports it as PNG. It does not scale the image to the player size or add JPEG compression.
Which video formats are supported?
Format support depends on your browser. H.264 MP4 and WebM usually work best. Some MOV, MKV, or H.265 files may not play directly.
Can I move through a video frame by frame?
Yes. Use the arrow keys or frame controls for fine adjustments. The standard step is approximately 30 FPS; exact boundaries in variable-frame-rate video depend on browser decoding.
Can I capture several consecutive frames?
Yes. Set “Frames after current” to a number from 1 to 120. VixFrame captures the current frame and that many following frames as separate full-resolution PNG files.
How do I capture a frame in fullscreen?
Press C while fullscreen to capture the current frame. A capture button also remains visible in the fullscreen player. Press F or Escape to leave fullscreen.
Can I download every captured frame at once?
Yes. Open the frame library and choose “Download all as ZIP.” VixFrame packages the original PNG files locally in your browser.
Do many captures use server storage?
No. Captures are stored in the current tab's memory. A large collection of 4K PNG files can use significant device memory, so download and clear them when finished.
Will my captured frames remain after a refresh?
Not in the current version. Download any frames you need before refreshing, closing the tab, or choosing another video.
