Render_Codes as of Reaper 7. Render-strings are binary strings encoded in Base64-format or as HEX-string(reaper.ini only). On Windows: some settings need FFMPEG 4.1.3 installed or are unavailable otherwise documented by Meo-Ada Mespotine, 13th of July 2022 - mespotine.de licensed creative commons cc-by-nc. It follows the scheme Byteposition: value/meaning Fixed values will be shown as the value or the ASCII-value (e.g. space - value 32). Flexible values are described and the possible values, that can be set at this position. Multibyte-values have the same description including value-range and which byte keeps the lowest values(0-255) and which the highest(2147483647 and such) Float-values follow the standard IEEE-standard, that C uses, when casting int to floats.
