I went a little early this year:
I’ve updated the script (gist) to handle a couple of new problems.
- Some of my iphone photos were upside down in the video as ffmpeg doesn’t see the Rotation EXIF. I installed jhead via homebrew deal with this.
- I installed sox to duplicate the background track as I took more photos and slowed them down a bit this year.
I have great fun with this every time I try it, I quite like the results but the tinkering with the script is the fun bit. I sure it could be made a lot more elegant but it works for me.
