Use the overlay filter
This will overlay the video on top of the image:
ffmpeg -loop 1 -i image.png -i video.mp4 -filter_complex "overlay=(W-w)/2:shortest=1" output.mp4
If you need to resize the video then add the scale filter:
ffmpeg -loop 1 -i image.png -i video.mp4 -filter_complex "[1:v]scale=400:-1[fg];[0:v][fg]overlay=(W-w)/2:(H-h)/2:shortest=1" output.mp4
You can use pad filter instead of an image
If you just want to add black padding you don't need an image and can use the pad filter.
ffmpeg -i video.mp4 -filter_complex "pad=1280:0:(ow-iw)/2" output.mp4
Using the player to do it instead
You could add the padding upon playback so you don't even need to re-encode:
ffplay -vf "pad=1280:0:(ow-iw)/2" input.mp4

1@OYAKHILOMEJOSHUA I added an example using the scale filter. If the answer is good you can accept it by clicking on the green arrow to the left.– lloganCommented Nov 25, 2015 at 18:33

1I think you should clarify that your scale will output 400x280 for his hypothetical input of 500x350 instead of 400x300, and thus leave blank space above and below. -1:300 may be a better option, assuming that he doesn't want to distort the image.– GyanCommented Nov 25, 2015 at 19:06
