FFmpeg creates emtpy (black) frames
- by resamsel
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:
