Introduction FilmStream mode 1-5
• 1080i
When eight vertical sub-pixels are combined, the total line count
becomes 540 lines. The second field is shifted four pixels to give an
interlaced picture.
• 720P
When six vertical sub-pixels are combined, then the total line count
becomes 720 lines. So, a 1920 x 720 image sensor is obtained with a 16:9
aspect ratio. When set to 60 frames per second, slow motion effects can
be achieved during post-production at different playback speeds.
• Cinemascope Aspect Ratio
When three vertical sub-pixels are combined, 1440 vertical lines are
obtained. By using the middle 1080 lines, a 2.37:1 aspect ratio is
achieved without the need for anamorphic lenses while maintaining
full 1920 x 1080 resolution. There is no need to crop the image or lose
resolution to get this aspect ratio.
