- Video stream will be converted to MPEG-2 with Intra-coded (I) frames; audio stream will be converted to LPCM with a bit depth of 16 bits and a sampling frequency of 48000 HZ; wrapper format is MXF (Material Exchange Format).
- According to Library of Congress, "For file-based compressed video, conform to or approximate MPEG-2_422 (4:2:2 Profile) at Main Level (aka MPEG-2 422@ML) or MPEG-2_MP (Main Profile) at Main Level (aka MPEG-2 MP@ML). Uncompressed or losslessly compressed copies are preferred to compressed (for future development)." Library of Congress Sustainability of Digital Formats: MPEG-2 Video Encoding (H.262)
