Also, 300MB for an HD movie is quite small. Typically, BD50 (Blu-ray) is 25-50GB. Converting that to 300MB would require significant compression. The paper should discuss codecs like x265, which are efficient but may affect quality. Bit rates might be around 2-5 Mbps for 1080p, but at 300MB, the bit rate would be much lower, perhaps around 4 Mbps for a 1.5-hour movie. That might result in visible quality loss, so the paper should explain the limitations.
