Save a video as GIF, scaling the height to 1000px and setting framerate to 15:

ffmpeg -i {{path/to/video.mp4}} {{[-vf|-filter:v]}} 'scale=-1:1000' -r 15 {{path/to/output.gif}}

Combine numbered images (frame_1.jpg, frame_2.jpg, etc) into a video or GIF:

ffmpeg -i {{path/to/frame_%d.jpg}} -f image2 {{video.mpg|video.gif}}

Convert AVI video to MP4. AAC Audio @ 128kbit, h264 Video @ CRF 23:
