How to make a video from pictures

Using Linux:

• open a terminal.
• create two subdirectories, in your current directory: tmp and img.
• put pictures into subdirectory tmp.
• go into directory tmp.
• using following command, rename pictures so that file names are sequentially numbered, starting from 1 (replace .jpg by a string corresponding to your pictures files names:

x=1; for i in *.jpg; do counter=$(printf %03d $x);  \
ln -s "../tmp/$i" ../img/img"$counter".jpg; x=$(($x+1)); done

• go into img subdirectory.
• then, type the command:

ffmpeg -r 5 -b 1M -i img%03d.jpg -s 800x600 ../video.mp4

• the -r parameter (5, here) is the number of pictures per second. The -b parameter is the bitrate (1 Mb/s, here). The -s parameter is the definition of the resulting video. video.mp4 is the name of the video file that will be created.

Then, using PiTiVi, edit resulting video, if necessary. Output format I use:

• container format: MP4
• video:
• 25 fps
• FFmpeg MPEG-4 part 2
• bit rate: 1000000
• encoding pass/type: VBR encoding - pass 1
• audio:
• codec: L.A.M.E. mp3
• bit rate: 64 (kb/s)
