in the original XSHEET-MYPAINT this xterminal commands are used to save animation as avi
png-s to jpg-s and than jpg-s to avi

convert -resize 800 -quality 100 -background white -flatten png_file_in jpg_file_out

ffmpeg -r str(vid_fps) -b 1800 -y -i jpgs_in out_filename

Saving as swf, flv works great

What is wrong with this code? Somebody can write a good code for saving multiple jpgs to avi or whatever video format.
