Introduction
This is the result we will create, an arrow video that dramatically slows down when the arrow hits the target, complete with smooth frame blending and freeze frames like in action movies. Let's get started. Hello, welcome back to the complete Adobe After Effects series from Cerdas Inovasi Digital. In this final episode of module two, we will manipulate the time of a layer, slowing it down, speeding it up, and freezing footage, using a championship archery video. Create a composition from the archery footage.
Step 1: Time Stretch
Select the layer and then open the layer, time, time stretch. Fill in the stretch factor to 200%, meaning the footage becomes twice as long and twice as slow. Click OK. The duration of the layer in the timeline stretches out.
Step 2: Frame Blending
When slowed down, each original frame is displayed twice, making the motion appear sluggish. Enable the frame blending switch in the switches column. After Effects blends adjacent frames, making the motion smoother. Notice the difference with space for a better feel.
Step 3: Restore Speed
For a more dramatic effect, we'll use another method. Open the time stretch again and reset it to 100%. Slow motion throughout the video is less engaging; what we want is to slow down only during key moments. Press Ctrl Alt T to enable time remapping.
Step 4: Time Remapping
A time remap property appears with keyframes at the start and end. The value of this property is the time the footage is displayed. Move to the second second and create a keyframe with a value of 2 seconds. This means the video runs normally up to this point.
Step 5: Slow Down at Key Moments
Move to the sixth second and type in the time remap value of 3 seconds. Between the second and sixth second, the footage only advances 1 second, 4 times slower. That's the slow motion exactly when the arrow hits. Frame blending remains active for smoothness. For a dramatic ending, move to the 7th second and add a time remap keyframe there.
Step 6: Freeze with Hold Keyframe
Select that keyframe and press Ctrl Alt H to toggle the hold keyframe. The icon changes to a square, its value is held, so the image freezes from that frame onward. Press space to preview the entire sequence.
Done!
Done. We've used time stretch, frame blending, and time remapping with keyframes for slow motion at specific moments. and froze the image using the hold keyframe. Module two is complete. And in the next module, we'll start animating layers with keyframes. Need a promotional video, logo animation, motion graphics for social media, or visual effects for short films?
