Originally, 8mm film was shot at 16 frames per second (fps) and super 8 was typically shot at 18 fps, although sometimes at 24 fps for more professional use. 16mm could have been shot at 16 fps, 18 fps, or 24 fps.
When transferring to digital, either DVD or digital files, most companies around the world deliver transfers that run at 24, 25, or 30 fps.
In the case of Super 8, to get from a native 18 fps playback to 30 fps, the digitization process needs to create duplicate frames. For the math to work, certain frames need to be doubled while others are only shown once.
At Memorable, we figured out how to deliver a native 16, 18, or 24 fps digital file after frame-accurate scanning of 8mm, super 8, and 16mm film.
In addition to the digital version being an exact replica of an original film’s frame rate, file sizes are typically 46% and 40% lower for 8mm and super 8 as we do not have to duplicate unneeded frames.
Since TV’s, computers, tablets, and smartphones display these native frame rates correctly, we can deliver digitized films with less data at the same quality.
