The Film Strip effects plugin works right inside FCP X and has many options that go beyond the simple slide projector look. Use dynamic effects so you can have complete control over your vintage effects without dealing with analog overlays.
Film Strip comes with a powerful slide effect that has all the options and controls you need: shape, size, and position variations of the slide. Control the vintage feel of the slide with variables such as blur, scratches, dust, jitter amount, light flash amount, etc. It also comes with special vignette and custom color grading option.
