Downloading SqView 0.4.1 for Mac from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this app available. The program lies within Design & Photo Tools, more precisely Viewers & Editors. This free software for Mac OS X is an intellectual property of Mihai Militaru. We recommend checking the downloaded files with any free antivirus.
From the developer:
SqCheck is an application that lets you view image sequences. The tool is aimed to be a professional tool for viewing animation frames rendered with 2D and 3D editing software tools. It is cross-platform, fast, and supports many image formats and OpenGL rendering.
