ld process vits - happycube/ld-decode GitHub Wiki
This application performs an analysis of the VITS (Vertical Interval Test Signals) and recalculates the white and black SNR values in the metadata. Note that any TBC file will already have this metadata provided by ld-decode. This tool is generally used along with dropout correction and stacking as the video content of the TBC is modified - running ld-process-vits therefore allows you update the SNR metadata in order to analyse the result (using ld-analyse).
Use the tool by specifying the required input .tbc file. The tool will backup the previous JSON file (to .vbup) before proceeding.
