In fact such codecs (ffv1, ProRes, DNxHD, OpenEXR, huffyuv, etc) are generally little or not at all compressed; the type of compression is intraframe --more suitable for editing, and the image quality (4:2:2 up; 10-bit color up; floating point; etc) is suitable for \textit{Color Correction}, \textit{Chroma Key} and \textit{Rotoscoping}. The use of mezzanine codecs leads to very large files, so you need to make sure you have enough storage space. +\paragraph{NOTE:} \CGG{} cannot do \textit{remuxing} without transcoding. For remuxing only, use \textit{ffmpeg} as shown in the following script. First move to the folder containing the files to be remuxed; the script takes all video files of a certain extension (in the following example \texttt{avi}) from the folder and its subfolders and makes a remux in a new container (in this example \texttt{mkv}) inside the new folder \texttt{remux}. The internal codec will remain the original one.
