七个步骤教你用PS制作高质量的gif动画教程

在InVision,GIF可不是消磨时间的玩意——它们在市场和教育方面扮演着强有力的角色。更有甚者,我们在首页上用的就是GIF,而不是基于代码的炫酷动画。

实际上,人们开始询问,"那些GIF你们怎么做出来的?"是时候透露一下秘密了

设计GIF

1. 秘密武器

这就是我不可告人的小秘密:所有的GIF是从视频文件开始的。我通常在ScreenFlow(www.telestream.net)里制作,我们也用它来制作产品视频。它足够简单,学起来很快,内置了一些非常有用的动画工具。

将动画导出成视频文件后,我通过文件>导入>视频帧作为图层将它导入到Photoshop里。

高级技巧: 如果ScreenFlow或After Effects超出你的预算,可以在Keynote里创作你的动画,然后导出成视频。是的,最后有这个选项。

2. 更少的颜色 = 更多的乐趣

如果想要惊艳的GIF,你得精挑细选地使用颜色。它不仅会使文件大小激增,使用更少的颜色也能让你制作更长、更复杂的GIF,而且文件仍然可以相对较小。(对我来说,1MB以下才算小)

3. 可能的话,使用运动模糊

像ScreenFlow和After Effects这样的软件,能输出带有运动模糊效果的视频。这不仅使你的动画看起来更专业,而且为了压缩文件尺寸,要从Photoshop中的GIF里删掉一些帧,还能帮你蒙混过关。

4. 懒(某种程度来说)

想像一下,本文开头的那个GIF,我本来还能加很多东西进去。带有用户名的小提示、一个鼠标指针点击加号按钮、鼠标滑过头像触发更多提示和悬停状态。人们不用看到每个细节就能了解情况,所以就只展示需要展示的部分——时间和文件大小是有限的。

导出GIF

下面这些诀窍可能会让你有些紧张,在这之前,先尝试直接导出GIF。如果文件大小可以接受,那么很好!继续这么做。如果它太大了,继续往下看。

5. 删除重复的帧

你的动画很可能在某处会暂时停止。仔细观察,你会发现这些片段包含了一大堆重复的帧,每个0.03秒。如果有10个重复帧,删掉9个,把剩下的那个时间设长一些,比如说1秒。

如果这没用,尝试重新导入视频,但这次要选间隔帧。它会显著缩减文件大小。

高级技巧: 这不是一条铁律,但如果你的GIF有超过150帧,你就得花好一阵子来削减文件大小。

6. 缩减色彩

在Photoshop中保存GIF时,右边能看到一个下拉菜单写着"颜色"。随便调调。只要GIF不会变成一团糟,设得越低越好。

7. 调整失真率

老实说,我甚至不知道失真率是什么意思。但我的确知道,如果你把它设置成1和10之间的某个数,就能在不降低画质的情况下剔除很多kb。

这些都不管用!求助!

如果上面方法都尝试过,但GIF大小就是压不下去,这时候需要倒退一步。你想做的是不是太多了?有没有其他方式达成你的目标?如果把它拆分成几个不同的GIF呢?就像大多数创意产品一样,如果你专注于一件事,你的GIF会表现更好。
