Gate Weave stands for mechanical swinging of a film strip while it is being pulled through a frame window in a film camera, projector or video coding device. It is often simulated intentionally to ‘breathe life’ into a digital cinema.

The mechanical movement of the film as it is pulled through the frame window of a film camera, projector or video encoder (film scanner) is more evident for small film formats and less evident for large ones.

The ‘jitter’ character is represented by the profiles of the four main formats. In order to change the parameters of any profile, you must first select the most suitable one and then switch to Custom mode.

All the usual effect settings will be available to you, and the parameter values will match the last selected profile.

The Custom settings allow you to configure Gate Weave as you like:

Period

The Period parameter determines the number of frames within which frame shifts occur. The larger this value is, the smoother the ‘bumps’ during playback are. With smaller Period mechanical shifts occur faster and ‘film’ yaws jerkier.

Translation X, Translation Y

The Translation X and Translation Y settings specify an amplitude of random shifts in a frame plane in conventional units.

Rotation

This parameter sets the maximum angle of random frame rotation in relative units.

Auto Zoom

This option automatically zooms an image to compensate frame shifts brought in by the current Gate Weave settings to crop any black gaps left around a frame where a geometric transformation occurs.

Impact

Within the Gate Weave tool the Impact parameter adjusts the overall impact factor, not the ‘opacity’ of the effect. When Impact is reduced, all shifts and geometric distortions in a frame are proportionally reduced.

💡 If you are experiencing excessive loss of detail with Gate Weave, and the Film Grain is enabled, it is possible to partially compensate the effect increasing the Film Resolution parameter
