Question

在这种情况下，以下代码在TextClip上成功地在单个预定义行上应用了效果，我想在.srt文件中的7行文本上应用相同的效果。

.srt文件中的7行文本是

第一行

第二行

第三行

第四行

第五行

第六行

第八行

当前，该效果应用于从不同角度出现的同一行文本。

我想保留动画，但是动画应该显示.srt文件中的一行新文本。

# WE USE THE PLUGIN findObjects TO LOCATE AND SEPARATE EACH LETTER

letters = findObjects(cvc) # a list of ImageClips


# WE ANIMATE THE LETTERS

def moveLetters(letters, funcpos):
    return [ letter.set_pos(funcpos(letter.screenpos,i,len(letters)))
              for i,letter in enumerate(letters)]

clips = [ CompositeVideoClip( moveLetters(letters,funcpos),
                              size = screensize).subclip(0,5)
          for funcpos in [vortex, cascade, arrive, vortexout] ]

# WE CONCATENATE EVERYTHING AND WRITE TO A FILE

final_clip = concatenate_videoclips(clips) final_clip.write_videofile('../../coolTextEffects.avi',fps=25,codec='mpeg4')

在SubtitlesClip（output.srt）上应用文本动画
