VGrade - Tux Grades Videos
summary
VGrade describes a command-line workflow that performs cinematic color grading of raw camera files using free tools (ffmpeg, ImageMagick/GraphicsMagick) and LUT management on inexpensive hardware. It implements 16/48-bit upconversion, automatic histogram leveling, denoising, deblurring and LUT stacking, orchestrated by a control script that extracts, previews, allows manual tweaks, batch-grades and assembles jobs so low-power notebooks/servers can parallelize renders; demos show good results though heavy denoising is slow, and a Debian package is planned.
