• FFMPEG : Stretch video to duration of audio [closed]

  22 juillet 2020, par duhaime

  I have a 10 minute mp3 audio file and an 8 minute mp4 video file, and I'd like to combine them into one mp4 file that is 10 minutes long.

  


  The video corresponds to the audio (the video shows birds flying and the audio is a musical passage generated by the positions of the birds), so I'd like to stretch it out so it matches the audio.

  


  Is there a way to accomplish this with FFMPEG or some other unix binary ? Any pointers would be super helpful !

  


• print list of video files containing "x" string in meatadata - Windows 10 [closed]

  30 mai 2020, par Harry Sanderson

  I have a large collection of video files which have the contents of the video listed in one of the metadata fields. for example one video might have "trees, birds, cars", another might have "birds, building, person".

  



  I'm looking for a command to print the filenames of all the videos that contain a specific string ie "birds" to a .txt file where the names would be separated by a comma so, "video1.mov, video2.mov" and so on.

  



  I know very little about this sort of problem, is it the sort of thing that can be done directly in windows cmd line, or would it require a python script ?

  



  Any help really appreciated ! :)
