I'm not exactly sure if there's a proper term for what I'm trying to do, I hope so because it's driving me nuts...

1) I have two directories. 2) Directory 1 has 286 jpg images with a WAV (main clip) 3) Directory 2 has 44 jpg images with a WAV (post-roll)

The sample above is real, however, the values are hardcoded. The total of frames for the main clip and the post-roll clip are variables.

For the moment I'm simply trying to get the images from both directories into a single mp4 using the following:

...

ffmpeg -aspect 4:3 -vframes 330 -r 15 -i images/%04d.jpg -i postroll/%04d.jpg output.mp

It runs fine but it completely ignores the images from the second directory. In the command line I set the vframes to the total of both directories but the output from ffmpeg clearly says 286:

...

frame= 286 fps=237 q=7.4 Lsize= 994kB time=19.07 bitrate= 426.9kbits/s

If someone would be so kind as to let me know where I'm going wrong I'd really appreciate it. :P

Yes this is because the second -i command tells to create another stream in parallel, which then isn't added to final output because it only contains just one video stream. You could use -newvideo, but that's not what you want to do, since you want to *concatentate* the two streams, which is something you *cannot* do directly with ffmpeg. Check the FAQs to see how to address the concatenation problem.
