[LAU] ffmpeg video generation: quality options

Hey hey, I've found the following command to generate a video from single frame images ffmpeg -r 25 -start_number 1 -i image%03d.jpg -c:v libx264 -r 25 -pix_fmt yuv420p out.mp4 My question is: the resultant videos seem quite small. Seeing that I have no knowledge of all the video quality parameters, could someone suggest better options? The input files are 1280x720 JPGs with possibly 16bits for color (standard POV-Ray output). Final destination is youtube. Any suggestions are very welcome. Best wishes and thanks, Jeanette -------- * website: http://juliencoder.de - for summer is a state of sound * SoundCloud: https://soundcloud.com/jeanette_c All you people look at me like I'm a little girl.
