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.

Video Grabber Tool

To open the Video Grabber tool, choose Tools -> Video Grabber in the Menu Bar.

The captured screenshots can be processed by a special video utility to make a video file.

The tool is available only in the Engineering and Sim editions of UNIGINE SDK.
