Creating a video from a single image for a specific duration in ffmpeg
VideoFfmpegVideo Problem Overview
How do I generate a movie using ffmpeg using a single image (image1.png) for a duration of 15 seconds with a specific resolution so when I play the video, the image will appear on screen for 15 seconds.
Video Solutions
Solution 1 - Video
ffmpeg -loop 1 -i image.png -c:v libx264 -t 15 -pix_fmt yuv420p -vf scale=320:240 out.mp4
- The -t 15 makes it 15 seconds long.
- The -vf scale=320:240 sets the width/height.
Make sure to use the latest ffmpeg version e.g. http://johnvansickle.com/ffmpeg/

Found this to be faster:
ffmpeg -framerate 1/10 -i DJI_0024.JPG -c:v libx264 -t 10 -pix_fmt yuv420p -vf scale=320:240 out.mp4
-t 10 making the video 10 seconds long, and setting -framerate 1/10. Divisor of framerate should be same number as the argument to -t. This made a jpeg with large resolution to be converted to a video in less then a second for me, while the other answer took about 40 sec. Also resulting filesize became slightly smaller. from 3.38MB to 3.17MB

use ffmpeg with the Parameter -r 0.01
for almost no frame rate. This makes the file about 65% smaller
But you maybe also need to cut the length with this Paramter -ss 00:00:00 -t 00:00:27
heres my code:
ffmpeg -r 0.01 -loop 1 -i image.jpg -i audio.mp3 -c:v libx264 -tune stillimage -preset ultrafast -ss 00:00:00 -t 00:00:27 -c:a aac -b:a 96k -pix_fmt yuv420p -shortest out.mp4 -y
