A video

way

Step 1: Open the PR software first, and then double-click the material panel to import the video material file.

Step 2: Select the newly created sequence of the video we just imported in the material panel, hold down the mouse and move it to the lower right corner, and then release it when the "+"sign appears under the small hand, thus creating a new sequence.

Step 3: Click "Effect" on the material panel, and then enter "Color Key" in the search box, or you can find "Keying" down.

Step 4: After finding the "color key", select it, then hold down the mouse and let go of this video on the timeline. At this time, our material video will have an "Fx" on the timeline.

Step 5: Find the "Effect Control" on the menu bar at the top of the video preview window, and then click it. At this time, we will see a lot of operations that can be performed on this video. Note that the video on our timeline must be selected and click "Effect Control" to have some functions, and the video shows white as the selected state.

Step 6: After clicking "Effect Control", we will find a "color key" under our effect control panel.

Step 7: Under the color key, there will be a small straw. Let's click on this little straw.

Step 8: After clicking on the small straw, click on the color block to be deleted from our video. At this time, the color we sucked through the straw has appeared in front of our small straw, and the color on our video has also been removed.

Step 9: The straw can't be sucked after being used once. How to continue the optimization? At this time, we can set some values under the "color key". When setting the value, we can adjust it while observing it.

By this time, our video has been cut, and the next step is to play it to see the effect. In the process of playing, if there is any material we don't want, we can choose to play a "key frame" and then continue to crop the image until we are satisfied, that's all.

How to cut the green screen material: click the plus sign behind the main track → click on the material library → click on the collection → select the grassland video → click on the add → add the picture in picture → click on the material library → click on the collection → select the green screen eagle → click on the add.

Click the chroma matting → the color picker points to green → the intensity and shadow are adjusted → the edge of the eagle and the green button are not clean. The solution is: choose eagle → click filter → choose black and white → choose black gold and silent film. Black gold works well.
