Solo Toggle for Keyframed Properties in After Effects

Introduce a “solo” toggle next to the stopwatch of keyframeable properties (e.g., Position, Scale, Rotation, Opacity) within the Timeline. This toggle would function similarly to the existing layer Solo feature.

Functionality:

• When a property is soloed:

  • Only soloed properties will animate.

  • All other animated properties on that layer will be temporarily disabled (their keyframes remain untouched, just inactive for playback and preview).

  • Soloed properties remain active during rendering/export, allowing isolated animation passes if needed.

• Multiple properties can be soloed at once, across the same or multiple layers — exactly like layer soloing.

• This feature enhances workflow focus, especially when fine-tuning easing curves or timing for a specific property without distraction from others.

Why It’s Needed:

• In complex animations, multiple properties often have overlapping keyframes, cluttering the timeline and complicating the animation process.

• Users frequently need to refine one property at a time (e.g., adjusting Position bezier handles without Scale influencing the motion).
