A 300mb movie file is relatively small for high-definition content but could be considered standard or high definition, depending on the movie's length and encoding efficiency. For a 1.5-hour movie to be around 300mb, it would imply a bitrate of approximately 450 kbps. While this might be sufficient for a low-quality SD video, it could also represent a poorly encoded HD video.
