With the passage of time not only the technologies advance but also our experience and supply, therefore the need arises to review work flows that have become obsolete

this is the case of the timcode tracks of the mxf files, in the past some systems used the timecode track called "FirstFrame", this forced a blanket correction of all the files in which this track was not written correctly

Finally now the same systems that 10 years ago I did not read the MXF standard timecode track now have this possibility but we clash against an archive of over 10 years of non-normalized mxf files ...

A punctual analysis of the TCs is born which sees the comparison between StartTimeCode and FirstFrame to delete the percentage of non-compliant files that must be modified to ensure that they can be used even after configuration changes to updated systems

an analysis that sees 24.8% of the files to be corrected

, a very significant quantity if it is not calculated, however, that all these assets are older than at least 2 years and that 81.3% are old recordings of LIVE and therefore unused for a long time, presumably, correctable without incurring problems of availability for the playout
