The problem is, it’s tedious to manually set the keyframes for a continuous line of small adjustments, as you need. What would fix the issue is a slight bit of movement. Sometimes, our animation lacks character or feels a little lifeless. LOOP OFFSET Expression: loopOut (offset) or loopIn (Offset) You may already be familiar with the loop expression in After Effects, but you may not be familiar with the more specific Offset Loop expression. Note: In order to create a less generic animation, you can also create 3 or more keyframes by using loopOut(type="cycle") expression instead. In After Effects, use the wiggle expression to create random movement by modifying numbers, not keyframes. Here is the list of After Effects expressions used in this tutorial. It all looks fine (even in a RAM preview), but when I render it, the brightness of the frame flickers randomly and constantly.

To add these go to Effects > Expressions Controls > Slider Control. I’m doing a fairly simple animation (mostly scaling and rotating) using only elements from an Illustrator PDF file in AE 6.5.
colormode (Optional, templatable): For lights that support more than one color mode, the color mode that will be activated. transitionlength (Optional, Time, templatable): The length of the transition if the light supports it. Alt -Click the stopwatch to create an expression and insert loopOut(type = "pingpong") to get an endless loop of both valuesĢ Keyframes: frame 0 > opacity 0%, frame 25 > opacity 100% To fix this, I’ll add two slider controls to my layer and rename them Frequency and Amplitude. Configuration variables: id (Required, ID): The ID of the light.Create a second keyframe and set its value to 100% Since there are billions of different ways to set up a composition with an almost infinite combination of footage types and effects my first guess would be that you have some frame rate problems somewhere or you are using GPU enabled effects that are fouling up.Create a keyframe by clicking on the stopwatch of outer glow 'opacity' and set its value to 0%.I'd suggest animate the 'Opacity' property of the outer glow:
