Capturing Screenshots and Frame Sequences
Video Grabber is a UnigineEditor tool for high-quality capturing of screenshots and frame sequences. Frame sequences are captured in a special non-real-time mode, allowing to get any fixed FPS even on a low-end hardware. In comparison with traditional CPU-based offline rendering, this tool allows much faster rendering thanks to GPU acceleration.
Video Grabber supports capturing of screenshots with extremely high resolution: 4K or even 8K images can be taken with a regular monitor. Also Video Grabber supports the professional EXR format in addition to the standard TGA, JPG, PNG and PSD formats.
The captured screenshots can be processed by a special video utility to make a video file.
