Note: as FFmpeg does not support detection of DPX bottom to top scan, we manually force vertical flip for FFmpeg encoding. We also force check because FFmpeg may support detection of bottom to top scan in the future and there will be too many vertical flip in that case (todo: detection of FFmpeg support of detection of bottom to top scan).
