本文為阿里雲智慧媒體服務IMS「雲端智慧剪輯」實踐指南第四期,透過運用官方提供的花字模版或自定義設計花字,完成豐富、精美的花字特效影片剪輯。
昱塵|作者
在影片後期剪輯中,“花字”是一種特別的存在。
透過使用適合影片的花字,不僅可以豐富影片內容,還可以讓影片傳達的資訊更加容易讓使用者接受,加深觀眾對於影片內容的印象。
對於做短影片營銷場景的客戶來說,花字更是起著至關重要的作用,不僅可以增強影片傳達資訊的能力,還可以增加影片的效果精美度。
影片中常用的花字,一般會包含幾個要素:文字顏色、紋理、字型、多層描邊、多層陰影以及背景及發光效果等。
本文主要介紹如何透過使用智慧媒體服務IMS「雲端智慧剪輯」增加花字,將從「如何使用官方花字」以及「如何自定義設計花字」兩方面來介紹強大的花字能力。本文效果實現較為簡單,將影片地址換成您自己的oss地址,即可以實現示例效果。
01 原始字幕
我們參考市面上比較主流的營銷類短影片剪輯模式,以下面這個流程作為demo展示的模版。
- 使用一張圖片作為影片封面,增加主標題、副標題以及描述文字;
- 使用三個橫屏拍攝的影片作為主體內容,輸出為豎屏影片(方便手機觀看),上下增加背景模糊效果;
- 每一個影片或者圖片,對應一段TTS口播,讓影片或者圖片與口播對齊,保證影片的流暢性;
- TTS口播同時搭配ASR字幕。
按照上面這個模版,我們先看一個不使用任何複雜字幕效果剪輯成的影片效果:
https://v.qq.com/x/page/p3502q8vcef.html
透過觀看影片發現,該影片中的字幕存在一些問題:
l 影片背景比較複雜,在字幕顏色和影片底色比較接近時,會導致字幕不夠清晰;
l 字幕比較單調乏味,影片內容不夠精緻,容易讓使用者產生視覺疲勞,降低傳播力;
l 字幕效果不夠突出亮眼,無法一眼就讓使用者把握影片關鍵資訊。

02 32套官方花字
為了解決上述原始字幕文字不明顯以及效果比較差等一些問題,我們可以用IMS中已整合的官方花字來豐富影片內容。阿里雲智慧媒體服務新增32套高階花字。
花字效果示例:
https://help.aliyun.com/document_detail/449561.html
可以簡單設定花字Id來一鍵式實現多種花字效果。使用官方花字對影片內容進行豐富的效果如下:
https://v.qq.com/x/page/r3502mwbj8h.html
對比沒有配置花字的原始字幕版本的效果,可以發現:使用官方花字製作的營銷短影片,不再會由於影片底色變化而讓人看不清字幕,從而更加能抓住觀眾的注意力,加深印象。
設定花字的方式也十分簡便,直接設定一個花字Id即可,比如"EffectColorStyle": "CS0002-000011",如果需要修改文字字型,可以使用自定義字型功能或者使用我們的官方內建字型庫。

03 自定義設計花字
當官方花字仍無法滿足影片製作效果的需求,我們也支援自定義花字功能。您可以靈活組織多層描邊效果,多層陰影效果,我們也支援設定高斯模糊,實現字幕發光效果。
在具體Timeline設定前,我們先來看一下自定義設計花字的成片效果。
https://v.qq.com/x/page/h3502f25vuk.html
自定義花字的API協議:
https://help.aliyun.com/document_detail/198823.html
首先,我們來看一個多層描邊的花字示例。我們以官方花字CS0001-000016這個效果為例。
CS0001-000016花字
仔細觀察,可以知道這個花字是透過從外到內疊加顏色逐漸變深的多層描邊來實現的,透過在SubtitleEffects中設定多層顏色逐漸變深的描邊效果即可實現這個花字。
Color欄位為RGB顏色值,Type設定為Outline表示描邊,Bord、Shift設定成0-1的小數時,表示相對字型大小的值,實際渲染時會乘以FontSize值,這樣即可實現不同字型大小下,花字效果基本保持一致。
SubtitleEffects是一個JSON陣列,越靠前的在渲染時會越在底層,所以底層描邊Bord需要比上層描邊Bord設定的稍大一些,否則底層的描邊會被上層的描邊遮住,從而失去效果。
該花字的文字顏色為白色,設定字型為站酷快樂體,據此可以設定字幕軌道引數為如下。
CS0001-000016花字SubtitleTrackClips引數解析:
{
"Type": "Text",
"FontSize": 130,
"Content": "阿里雲剪輯",
"Spacing": 2,
"Alignment": "TopCenter",
"Font": "HappyZcool-2016",
"FontColor": "#ffffff",
"SubtitleEffects": [{
"Color": "#c6f295",
"Type": "Outline",
"Blur": 0.0,
"XBord": 0.16,
"YBord": 0.16,
"XShift": 0.0,
"YShift": 0.0,
"Opacity": 1.0
}, {
"Color": "#99dda3",
"Type": "Outline",
"Blur": 0.0,
"XBord": 0.12,
"YBord": 0.12,
"XShift": 0.0,
"YShift": 0.0,
"Opacity": 1.0
}, {
"Color": "#66c19c",
"Type": "Outline",
"Blur": 0.0,
"XBord": 0.08,
"YBord": 0.08,
"XShift": 0.0,
"YShift": 0.0,
"Opacity": 1.0
}, {
"Color": "#138b8a",
"Type": "Outline",
"Blur": 0.0,
"XBord": 0.04,
"YBord": 0.04,
"XShift": 0.0,
"YShift": 0.0,
"Opacity": 1.0
}]
}
我們再來看如何自定義實現字幕發光效果。
CS0002-000015花字
我們以CS0002-000015這個花字效果為例。仔細看,這個花字整體是由兩部分組成的,一部分為底部的文字投影,一部分為上層的文字主體。
再細細觀察,可以發現,文字投影部分最外是由一層淡藍色發光效果構成,中間是一層描邊,描邊中間包含深藍色的文字實體。發光的效果我們是透過給陰影增加模糊效果來實現。
上層文字主體部分,是由一個層描邊包含文字主體的輪廓構成,文字主體部分有半透明效果,所以該花字效果解析的字幕軌道引數如下:

"Font": "HappyZcool-2016",
"FontColor": "#00e6ff",

"SubtitleEffects": [{

"XBord": 0.02,
"YBord": 0.02,
"XShift": 0.04,
"YShift": 0.04,
"Opacity": 1.0
},
{
"Color": "#008c9e",
"Type": "Shadow",
"Blur": 0.0,
"XBord": 0.04,
"YBord": 0.04,
"XShift": 0.04,
"YShift": 0.04,
"Opacity": 1.0
},
{
"Color": "#29e6ff",
"Type": "Outline",
"Blur": 0.0,
"XBord": 0.02,
"YBord": 0.02,
"XShift": 0.04,
"YShift": 0.04,
"Opacity": 1.0
},
{
"Color": "#ffffff",
"Type": "Outline",
"Blur": 0.0,
"XBord": 0.02,
"YBord": 0.02,
"XShift": 0.0,
"YShift": 0.0,
"Opacity": 1.0
}
]
}
按照上面這個自定義花字的方法,我們可以實現任意想實現的花字效果。上面這個探店營銷短影片的timeline就這樣實現出來了。
