• Transcode any video to mp4 with max. 800 width or max. 800 height + watermark

  27 décembre 2018, par Mike

  I need a ffmpeg command that works with every video (with audio) format / type to encode it to h264 mp4. The output may have a maximum width of 800px and a maximum height of 800px. It would also be necesary to add a watermark in to bottom right corner... Is there a way to get all those things done with a single command line ? Even if it’s WMV, MOV, 3gp and whatever filetype is beeing used ?

  I’m trying to render a animation.ArtistAnimation object into a 24 fps video file in format mp4.

  I have search about and I reached this. However, even after compiling ffmpeg I get this error message :

  C:\Users\trite\OneDrive\Documentos\MusiTex\Python\venv\Scripts\python.exe 
  
  "C:/Users/trite/OneDrive/Documentos/MusiTex/Python/venv/Saving Animation.py"
  
  Traceback (most recent call last):

  packages\matplotlib\animation.py", line 161, in __getitem__
  
      return self.avail[name]
  
  KeyError: 'ffmpeg'
  
  
  
  During handling of the above exception, another exception occurred:
  
  
  
  Traceback (most recent call last):
  
    File "C:/Users/trite/OneDrive/Documentos/MusiTex/Python/venv/Saving

      'Requested MovieWriter ({}) not available'.format(name))
  
  RuntimeError: Requested MovieWriter (ffmpeg) not available
  
  
  
  Process finished with exit code 1
  
  </module>

  What is the problem with ?

  I would really appreciate if you can help me. Actually, if there is other ways to saving/render this kind of object into a video file (preferably mp4) I will be delighted to hear them.

  Thank you very much

• Video Edit with FFMpeg

  22 octobre 2020, par Max

  I have been trying to figure out small video editing with FFmpeg in Android.

  


  I want to make video to be stopped in some seek position with overlay for a few seconds.

  


  For example, there is original video, and overlay image file.

  


  After 3 seconds, the video will be looked as stopped with overlay for a few seconds (there will not be audio).
In a word, 5 seconds of video needs to be 8 seconds of video. (certain frame needs to be inserted with overlay for 3 seconds.)

  


  How can I solve this with FFMpeg ? If anyone know FFMpeg command for this edit, please help me.
