I have a set of images from a timelapse shot (172 JPG files) that I want to convert into a movie. I tried several parameters with FFmpeg, but all I get is a video with black frames (though it has the expected length).

ffmpeg -f image2 -vcodec mjpeg -y -i img_%03d.jpg timelapse2.mpg

The command above creates this video: http://sdm-net.org/data/timelapse2.mpg

What I'm expecting is something like this (created with Time Lapse Assembler.app): https://vimeo.com/39038362 - This is my fallback option, but I'd really like to create timelapse movies from a script.

I'm on OSX Lion (10.7.3) with FFmpeg version (0.10) installed via Homebrew.

I also tried to find a proper version of mencoder for OSX, but this doesn't seem to be an easy task. Also, ImageMagick's convert doesn't seem to work nicely, it creates really bad output and it seems there's not much I can do about it...

Edit:

With libx264 and an mp4 container:

ffmpeg -f image2 -y -i img_%03d.jpg -vcodec libx264 timelapse4.mp4

Output:

You need to place the codec option after the input option. Try that! –  slhck Mar 27 '12 at 8:54
    
@slhck: I tried "ffmpeg -f image2 -y -i img_%03d.jpg -vcodec mjpeg timelapse3.mpg", which created this video: sdm-net.org/data/timelapse3.mpg (doesn't even play on my VLC...) –  resamsel Mar 27 '12 at 9:47
    
Hmm. Why use the MJPEG option? Try another codec like libx264 with an MP4 container, and please post the full uncut output! –  slhck Mar 27 '12 at 10:12
    
I edited the post with libx264 and an mp4 container, hope this helps! –  resamsel Mar 27 '12 at 10:32

Well, this is embarassing. Something happened to the source images, somehow they were all overwritten by black images - that's why the resulting video was all black. My apologies for keeping you from solving real problems. And thanks for trying to help me out on that!

Oh. That'd be a good reason! –  SamB Mar 27 '12 at 21:15
    
Voting to close the question as too localized, since that's probably not gonna happen to someone else. –  slhck Mar 29 '12 at 7:51
