• 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"))])

• MoviePy on EC2 Instance Super Slow

  27 janvier 2020, par connorvo

  No matter what size EC2 instance I use, MoviePy.write_videofile() takes forever.

  I ran it on a t2.micro, c5.large, and c4.2xlarge and they all projected to take the same amount of time ( 7 hours).

  I have a 720mb mp4 file that I am adding a 30mb mp4 file to the beginning of and then putting a text overlay on the entire video (just static text saying the company name in the bottom corner).

  final_video.write_videofile(
  
      f"{FINAL_VIDEO_FILENAME}.mp4", 
  
      fps=60,
