• Mirrored Arabic Letters using TextClip Moviepy

  4 août 2020, par Sam

  I am trying to render the video which contains arabic letters. let's use مرحبا for the example. After video rendered the result is mirrored.

  


  background = mp.ColorClip(mobile_size, (255, 255, 255), duration=0.5) #float(audiolength.info.length)
text1 = mp.TextClip(english, fontsize=45, color=fcolor, font=Font, size= (mobile_size[0], 185), method = 'caption', align="south").set_duration(0.5) #float(audiolength.info.length)
text2 = mp.TextClip(formatChineseSentences(translated).encode("utf-8"), fontsize=45, color=fcolor2, font=Font, size= (mobile_size[0], 185), method = 'caption', align="north").set_duration(0.5) #float(audiolength.info.length)

clip1 = mp.CompositeVideoClip([background, text1.set_position(('center', "top")), text2.set_position(('center', "bottom"))])
