Working with After Effects is fun since there are so many features to explore. It’s like a never ending experiment and you will discover something new everyday. When I am talking about Rotating layers in After Effects, those who are familiar with the software must have thought about Keyframes. No doubt, Keyframes is the key to animating layers in After Effects. You can move things from one point to another, scale objects and rotate layers. The most common method of rotating layers in After Effects is by adding keyframes to the rotation property and changing the rotation amount manually. But, with an After Effects Expression, you can set an automatic rotation to a layer.

For instance, if you want to rotate the blades of a Helicopter, you can use the keyframes to do so. But, with keyframes, it is difficult to adjust and control the rotation speed. You need to move the keyframes in or out to adjust the speed. So, using an Expression instead of manual animation can save you some time and results will be much better. For detailed explanation, watch the Quick Tip video below.

The After Effects Expression about which I am talking here is the TIME expression. Instead of adding the rotation value manually, we tell our Layer’s rotation property to Multiply the total length of timeline with another user defined value or integer. Therefore, the expression comes out to be TIME*(any user defined number).
How it Works
Let’s take an example – I have a square which I want to rotate by 360 degrees (one full rotation) and length of my timeline is 5 seconds. There are two methods through which I can achieve my goal. One is the manual keyframe method. I can set a keyframe at the starting frame of my timeline and one keyframe at the end and change the rotation value to 360 degrees. That means, the square will cover a full rotation of 360 degrees in 5 seconds.
To get the same result with an expression. Simply divide the value of degrees i.e. 360 degrees by the length of your timeline, in this case, 5 seconds. The result which you get is the user defined value mentioned in the above expression. On dividing 360 by 5, the result is 72. So, the After Effects Expression to rotate the square by 360 degrees or one full rotation in a 5 seconds long composition will be TIME*72.
In case of rotating the blades of helicopter or where you want your layer to rotate continuously, use can use any value in the expression. The higher the value, the higher will be the rotations and speed.

To Rotate a layer automatically with After Effects Expression.
- Select the layer which you want to rotate and hit R on your keyboard to open up the rotation properties.
- Hold down ALT key on your keyboard and click on the stopwatch at the rotation property. The same stopwatch which we use to add keyframe. By holding down the ALT and clicking on the stopwatch, instead of adding a keyframe, Expressions text area will be opened.
- Delete the existing transform.rotation from the Expressions area and type in your new Rotation Expression – TIME*(any user defined number).
- Click anywhere to on the screen to finalize the expression. After Effects will notify you of any errors, if found.

Chemotherapy is a powerful drug regimen that is used to kill cells that replicate rapidly. The chemotherapy process is physically demanding, and many patients notice side effects after a single treatment. There are a variety of different drugs used for chemotherapy. Depending on the choice of chemotherapy medication, the doctor may be able to predict the likelihood of the patient developing different side effects.
Types
Non Specific Effects
Fatigue, nausea, vomiting, loss of appetite, diarrhea and fever are all common side effects that may occur after the first session of chemotherapy. Some people experience these symptoms immediately after their first session, while others may develop some or all of these side effects within hours of the completion of their first chemotherapy session. Other early chemotherapy side effects include mouth sores, pain and hair loss, but these side effects typically develop in the weeks after treatment begins.
Time Frame
It is difficult to determine the exact time frame for developing side effects of chemotherapy. The most well-known side effect, hair loss, does not normally start until 2 weeks after the first chemotherapy session. However, many people don't make it out of their first chemotherapy session without experiencing profound nausea and even vomiting or diarrhea. Fatigue typically develops soon after the end of the first chemotherapy session and may last a day or so after each treatment or plague the patient throughout the course of treatment.
Considerations
One side effect of chemotherapy that few people are able to escape is fatigue. Chemotherapy is typically given as an outpatient service, and many people mistakenly believe that because they are returning home the same day, they don't need to take any special considerations for their health. Having some help arranged at home can greatly reduce the fatigue levels of the chemotherapy patient. Someone to prepare proper meals and help with household chores will allow the patient to recover better between chemotherapy sessions.
Misconceptions
Often people believe that their hair will immediately fall out after their first chemotherapy session. Hair loss typically begins in the first month of treatment, but not immediately. The hair loss is also gradual. Losing your hair can be an emotional process, but the fact that it occurs gradually, over a period of weeks, may allow the patient time to come to terms with the process. Side effects that cancer patients should prepare for early in the treatment process are various digestive issues, including nausea and loss of appetite, and overwhelming fatigue. Preparing for these allows the patient to keep her strength up for the rigors of treatment.
Prevention/Solution
While there is no way to prevent side effects from chemotherapy, there are ways to manage them. By carefully monitoring how they feel, patients can work with their doctors to develop a plan for controlling fatigue, nausea and other digestive issues. After the initial chemotherapy session, the oncologist may provide medications that will lessen the effects of certain side effects or wait until the patient develops specific complaints before offering treatment.
