Frame Interpolation

Every video company has some type of technology designed to reduce motion blur and improve the clarity of fast action content. Frame Interpolation compares consecutive image frames and inserts intermediate image frames between them, resulting in smooth fast-moving video. While most manufacturers give it a proprietary name, Epson just lists the feature as Frame Interpolation in its menu.

I never recommend using it when watching movies since it creates “soap opera” like video, which changes the director’s intent. While motion processing normally isn’t required for 24P movie material, CFI can be beneficial when viewing sports.

While I normally wouldn’t turn on frame interpolation when viewing normal HDTV, when sports content, there is definitely a benefit to smoother, clearer motion. The nice thing is that the feature includes multiple settings so you can dial in the effect to suit your personal taste.

On previous Epson pixel shifting projectors, this feature could not be combined with Pixel Shifting so it is only available when viewing 1080P content with 4K Enhancement set to OFF. The projector’s version of 4K UHD PRO was not fast enough to display double the visual frames and pixel shift at the same time.

However, the newer and far faster version of Epson’s 4K UHD PRO technology built into several Epson projectors like the Pro Cinema LS12000 allows simultaneous pixel shifting and frame interpolation for content below 120 Hz.

Frame Interpolation is only available when IMAGE PROCESSING is set to Fine in the projector’s menu. When IMAGE PROCESSING is set to Fast, features like Frame Interpolation, Noise Reduction, and MPEG Noise Reduction are disabled to reduce input lag when gaming to as low as 20ms.
