[FFmpeg-user] Encode single pictures to movies

[Tom Mackey]

Lou,

Thanks for your prompt reply.  * *As all the images were a little different
I used
mogrify -resize 1920x1080  as I wanted to show the image on HD tv.
The size of the images after this were around 1600 x1080 as they were in 4
x3 format

The output of ls -l is

ls -l img*.jpg
-rw-rw-r-- 1 name name 194172 2013-01-31 22:30 img1.jpg
-rw-rw-r-- 1 name name 238917 2013-01-31 20:56 img2.jpg
-rw-rw-r-- 1 name name 222021 2013-01-31 20:56 img3.jpg
-rw-rw-r-- 1 name name 178924 2013-01-31 20:56 img4.jpg
-rw-rw-r-- 1 name name 256311 2013-01-31 20:56 img5.jpg
-rw-rw-r-- 1 name name 468532 2013-01-31 20:56 img6.jpg
I can't see any difference that causes it not to include 4,5 and 6



The output from the console is

 ffmpeg -f image2 -r 1/5 -i img%d.jpg out.mp4
