moviepy.video.fx.Freeze

class moviepy.video.fx.Freeze.Freeze(t: float = 0, freeze_duration: float = None, total_duration: float = None, padding_end: float = 0)

Momentarily freeze the clip at time t.

Set t=’end’ to freeze the clip at the end (actually it will freeze on the frame at time clip.duration - padding_end seconds - 1 / clip_fps). With duration you can specify the duration of the freeze. With total_duration you can specify the total duration of the clip and the freeze (i.e. the duration of the freeze is automatically computed). One of them must be provided.

apply(clip: Clip) → Clip

Apply the effect to the clip.

copy()

Return a shallow copy of an Effect.

You must always copy an Effect before applying, because some of them will modify their own attributes when applied. For example, setting a previously unset property by using target clip property.

If we was to use the original effect, calling the same effect multiple times could lead to different properties, and different results for equivalent clips.

By using copy, we ensure we can use the same effect object multiple times while maintaining the same behavior/result.

In a way, copy makes the effect himself being kind of idempotent.
