     13|| GOP size || `-g`              || integer >= 1   || For archival use, GOP-size should be "1". Doing so increases error resilience at the cost of compression ratio. ||

     39|| GOP size                   || `-g`              || integer >= 1   || For archival use, GOP-size should be "1". The compression gain from larger GOP size is lower compared with version 1. ||
    4040|| Version                    || `-level`          || 1, 3           || Select which FFV1 version to use. ||
    4141|| Threads                    || `-threads`        || integer >= 1   || The number of threads to use while processing. Adjust this to match how many of your available CPU cores you want to use. ||
