Hi,

You are not alone in experiencing issues like this after CapCut app updates. Sometimes features get changed, moved, or unfortunately, bugs get introduced. Here's a breakdown of possibilities and what you can try:

1. Feature Relocation/Change: CapCut may have redesigned how adjustments for certain effects work.
   • Check Carefully: When you apply the "Slow Zoom" effect, look very closely at the timeline and the settings panels. Is there a new button, icon (like a small graph, sliders, or "Adjust" text), or menu that might now contain those controls? Sometimes they aren't immediately obvious.
   • Different Effect Name?: Is it possible the effect with adjustable bars has been renamed, or there's a similar new effect that now offers those controls? Browse the effects library again.

2. Alternative: Keyframes: While not as convenient as the preset bars, you can manually replicate a slow zoom using keyframes. This gives you precise control:

   • Select the clip on your timeline.
   • Move the playhead to where you want the zoom to start.
   • Tap the keyframe button (usually looks like a diamond shape, often near the scale/position properties). This sets the initial scale and position.
   • Move the playhead to where you want the zoom to end.
   • Adjust the clip's scale (zoom in) and position (to keep the subject centered if needed). A new keyframe will automatically be added.
   • CapCut will now smoothly animate the zoom between these two keyframes. You can add more keyframes for more complex movements.
   • For smoother transitions, use the Graphs feature to modify the speed curve.

3. Applying the Zoom Lens Effect:

   • Select your video clip in the timeline.

   • Tap on "Effects" and choose "Video Effects."

   • Navigate to the "Basic" category and select "Zoom Lens."

   • Tap "Adjust" to customize parameters like Speed and Range.

   • Apply the effect and adjust its duration by dragging its edges on the timeline.
