1. Prior to Starting 1-1. Overview FOR-A LUT Convertor allows you to convert 1D-LUT (Color Lookup Table) files from various camera log formats to a FOR-A s proprietary format (FOR-A 1D-LUT), which is a dedicated format for FOR-A products, FA-9600 and USF-106UDC/DC-12G. 1-2. Key Features Conversion from various camera logs into FOR-A 1D-LUT Supported formats: Autodesk Lustre, Adobe After Effect, DaVinci Resolve and Sony SRW-1 FOR-A 1D-LUT file editing 2. LUT Converter Installation 2-1. System Requirements Install the converter into a PC running Windows 7 or higher. Net Framework 4.6.2 is required. 2-2. Installing the LUT Converter (1) Go to the LUT Converter folder in the supplied CD-ROM and double-click setup.exe. (2) If.NET Framework 4.6.2 installation is required, a dialog window as shown at right appears. Click Accept. 4
(3) Click Yes to start the.net Framework installation. (4) Click Next. (5) Choose an installation directory. Click Next. (6) Click Next. 5
