First, take your video video into Photoshop, and make sure the Motion workspace is active (found under Window > Workspace). This will give us a simple timeline. Using the blue guides to the left and right of the timeline, select a 1-2 second segment that will form the basis of your cinemagraph. You don't need to be exact, since we can trim some of those extra frames in the next step.
1,首先,把你的視頻導入photoshop, 然後確認Motion workspace 是否能用(found under Window > Workspace).,這個會顯示出一個時間軸,用藍色的指示圖,選取1-2秒片段作為你 cinemagraph的基本部分,其實不用很精確,因為我們也可以把那些多餘的frames在下面的步驟里修改掉。
Once you've selected your segment, we're going to export the selection as a new movie. ChooseFIle > Export > Render Video, and accept the default settings. Now, close your document, andchoose File > Import > Video Frames to Layers, selecting the video file you just exported. This will import each frame as a new layer, which is crucial for the masking process.
In our sample video, there's lots of motion, with people moving up and down the various escalators —except for one. This escalator is empty, and thus, perfect for animating, while freezing the rest of the busy people pictured in this scene. In the Layers palette, the first layer is going to serve as our animation's anchor frame. With the first layer selected, ensure that "Unify Layer Visibility" is activated. This ensures our static anchor frame will repeat itself in each successive frame.
Now, the fun part — and also the most time consuming. Select the second layer/frame. Using the marquee tool, or any other selection tool of choice, create a layer mask around the area of motion you'd like to retain. Repeat the process for each frame that follows. You can preview your progress at any time using the motion timeline. If all goes well, you should see a static image, with only the masked areas exhibiting any sign of motion.
Depending on the framerate of your source material, the animation might not be as smooth as you'd like. This can be fixed by selecting every frame in the timeline, right-clicking, and and choosing a new delay value. Try experimenting with different settings to see what works best. Also, you might find that your chosen subject or animation doesn't loop all that smoothly. In some cases, it's a simple matter of copy/pasting all your frames to the end of the timeline, and choosing Reverse Frames from the timeline bar's options menu.
When that's done, click When that's done, click File > Save for Web & Devices. Make sure that GIF is your selected export format. You an even preview the final image if you'd like.
6.最後一步就是存儲了,File > Save for Web & Devices. 存儲成網頁模式,確定GIF導出的格式。大功告成。
