It's not as simple as cutting and dragging in Premiere to be a protagonist wearing cute rabbit ears and playing the video of "Little White Rabbit Princess" in fairy tales. The difficulty is to let these lovely ears "grow" tightly on the hero's head, which makes people move their ears. A little difficult? Don't worry, simple operation and your curiosity, plus some Hollywood imagination, we can also make magical effects.
Don't move too much when shooting.
Because rabbits have long ears, there should be enough space on the protagonist's head when shooting. Because rabbit ears are mostly white, try to avoid white backgrounds, such as white walls. Greening forest belt is a good choice. The camera must be mounted on a tripod to take a stable picture. Blur the background with a telephoto and a large aperture. Don't push or pull the lens. It is appropriate to take the mid-close shot as the scene. The protagonist's head should not look around, but look straight into the camera. If you think the picture is too rigid, you can also let the protagonist walk around, but you need to walk along the vertical axis instead of taking the S shape; Don't swing your head too much, so as not to be more difficult to track later. You can do more complicated movements after you have some experience.
Make a mask to frame the face of the protagonist.
Import the material into Premiere CS3 (hereinafter referred to as Premiere) and output a frame as a mask (just like a black paper with a hole cut, the black part covers the unwanted part of the picture, while the white part is the opposite). Open Premiere, select the face and the part with hair, the feathering value is 6, fill it with white, reverse the selection, fill it with black, and save it as "mask". jpg”。 It only takes 3 minutes to achieve this step.
Make ears and save them as "transparent" materials.
Download a large-size picture of a rabbit from the Internet, open Photoshop, and use various selection tools to outline the rabbit's ears. The feathering value is set to 1. Copy and paste it into a picture just taken from the original material, and freely change the size of the ear to match the head. Name the pasted layer "Rabbit Ear", delete the background and save it as "Rabbit Ear". Private Sector Division ".
Follow the road and let your ears follow.
Go back to Premiere, put the same original material in video track 1 and video track 3, and put "rabbit ears". PSD "is put into video track 2, and" Mask "is put in. Jpg "into video track 4. Turn off Show Eyes for video tracks 3 and 4 and select Rabbit Ears. "PSD" of video track 2, and then click the motion option in the effect control window to adjust the position, rotation and scaling parameters of "Rabbit Ear". PSD "is based on the swing and distance of the protagonist's head. Generally, the start and end of an action are set as key frames, so that the computer can basically calculate the intermediate transition parameters automatically.
Feathering, color correction, perfect synthesis
After setting the parameters of video track 2, right-click to copy and paste the key frame parameters into the face mask. Jpg of video track 4, open the "Show Eyes" of video tracks 3 and 4, and select video special effects → key points → track mask in the effect window to pull the original material of video track 3. The effect parameters are set as: Mask → Video 4; "Synthesis and Use" → Mask brightness.
The role of video tracks 3 and 4 is to cut out the face and part of the hair and fold it on the surface of the ear. Because the mask is feathered, the cut local image blends well with the ear. Finally, color correction, so that the ear and the protagonist's skin color are close.
Looking at the effect now, do you feel that the ears really grow from the head of the protagonist?
Of course, this case is only set up for us to clearly show the production process. You can set tails, wings and even masks for people.
