Tweening and Keyframing

“Describe the steps you would take to create an animation in Photoshop where a ball moves from the left side of the frame to the right side of the frame, then disappears. Specify whether you would use video layers or video groups and why. You have created an animation using video layers in Photoshop, but you want one specific frame to last for three frames in the timeline. Explain how you would achieve this effect, detailing the steps and tools you would use. You've created a character animation using video groups in Photoshop. You need to adjust the position of the character in only one specific frame. Explain how you would accomplish this without affecting the position of the character in other frames.”
