• Create a time-lapse movie by speeding a video up to the time of an audio file

  26 décembre 2014, par Peak Reconstruction Wavelength

  Input

  1. Audio file, mp3, 2 minutes
  2. Video file, mov, 1920 x 1080, 29 fps, 13 minutes

  I want to know which command to use to have a time-lapse movie mov as a result, which is two minutes long while remaining 29 fps, so it speeds up to match the time of 1. and the audio track of 2. is replaced with 1..

  My approach

  ffmpeg.exe" -i "x.MOV" -i "y.mp3" -vcodec copy -async 10 -ab 128k "e.MOV"

  which only puts the audio file to the beginning.

  When i use the above code, the file is converting to 1.flv with 0 bytes. No data is in 1.flv file.

• Script to make movie from images

  6 décembre 2014, par Alex TheWebGroup

  Hello I want a script or a way to make a video from images. I have a folder with a lot of pictures named randomly like "flowers.jpg", "tree.jpg", etc.

  I also have an "intro.jpg" photo which I want to add at the start of every video.

  What I want exactly is to create a video (any format, .avi etc) for a custom duration with only two photos like this :
  intro.jpg (10-20 seconds or how much i want) + tree.jpg (1 hour or how much i want)
  intro.jpg + flowers.jpg
  ...
  and so on.

  Sorry for being a newbie, but I have no clue how to accomplish this.
