Extracting images (jpeg) from a video:
ffmpeg -i foo.avi -f image2 f%03d.jpg
ffmpeg convert to photo-jpeg
ffmpeg -i input.mov -pix_fmt yuv420p -vcodec mjpeg -qscale 1 output.mov
ffmpeg -i f%03d.jpg -pix_fmt yuv420p -vcodec mjpeg -qscale 1 output.mov
Add Watermark/Overlay & H264 output
ffmpeg -i image.%04d.jpg -vcodec libx264 -b 15M -f mov -g 30 -bf 3 -b_strategy 1 -coder 1 -qmin 20 -qmax 51 -sc_threshold 40 -flags +loop -cmp +chroma -me_range 16 -me_method hex -subq 5 -i_qfactor 0.71 -qcomp 0.6 -qdiff 4 -directpred 1 -flags2 +fastpskip -dts_delta_threshold 1 -acodec libfaac -ab 192k -y -vf "movie=0:png:o.png, scale=1280x720 [wm];[in][wm] overlay=0:0:1 [out]" -s 1280x720 output_watermark.mov
Another version. For windows build and newer version of ffmpeg
ffmpeg -i image.%04d.jpg -vcodec libx264 -b 15M -f mov -g 30 -bf 3 -b_strategy 1 -coder 1 -qmin 20 -qmax 51 -sc_threshold 40 -flags +loop -cmp +chroma -me_range 16 -me_method hex -subq 5 -i_qfactor 0.71 -qcomp 0.6 -qdiff 4 -directpred 1 -flags2 +fastpskip -dts_delta_threshold 1 -acodec libfaac -ab 192k -y -vf "movie=o.png, scale=1280:720 [mask];[in][mask] overlay=0:0:1 [out]" -s 1280x720 output_watermark.mov
Split video
use -ss 00:00:01.000 #start position
-t 00:00:30.000 #duration
Padding & Overlay
//padding 90px top and bottom
ffmpeg -i image.%04d.jpg -vcodec libx264 -b 15M -f mov -g 30 -bf 3 -b_strategy 1 -coder 1 -qmin 20 -qmax 51 -sc_threshold 40 -flags +loop -cmp +chroma -me_range 16 -me_method hex -subq 5 -i_qfactor 0.71 -qcomp 0.6 -qdiff 4 -directpred 1 -flags2 +fastpskip -dts_delta_threshold 1 -acodec libfaac -ab 192k -y -vf "[in]pad=1280:900:0:90:black[pd];movie=o.png, scale=1280:900 [mask];[pd][mask] overlay=0:0:1 [out]" -s 1280x720 output_padding90.mov

ffmpeg -i winter_clip.mov -vcodec wmv2 -b 12000k -ar 44100 -ab 192k -ac 2 -y -s 720x406 output.wmv
use ffpreset in windows
ffmpeg -i "d:\inputfile.avi" -vcodec libx264 -crf 25 -s 1600x900 -vpre "d:\ffmpeg\ffpresets\libx264-veryslow.ffpreset" -acodec libmp3lame -ar 44100 -ab 128k -f flv tmp.mp4
