Convert a sequence of JPG images into a MP4 video using FFMPEG

If you have a sequence of images like the screen shot below, it is quite straightforward to use ffmpeg to concatenate them into a single video file. 

Obviously, you need to specify the image file name and sequence pattern, the frame rate to show each image as shown in the example ffmpeg command below.

$ ffmpeg -hide_banner \
-f image2 \
-framerate 1 \
-start_number 1 \
-i %02d.jpeg \
-vcodec mpeg4  \
output.mp4

where -f specifies the input format as image,

-framerate specifies the rate in Hz at which to display each image frame,

-start_number specifies the starting number of the image frame sequence,

-i specifies the file name and sequence pattern, e.g. %02d means a pattern of 2 digits with a prefix character '0' for single digit numbers,

-vcodec tells ffmpeg to output mpeg4 format.

 Running the command will display the following output and generate the output video file output.mp4.
