Are the png-files ok?
Can you see them with a picture-viewer.

You can also create videos with mjpegtools: "http://mjpeg.sourceforge.net/";
# png2yuv -f 25 -Ip -L0 -j VIDEOSHOT_NAME.%010d.png | mpeg2enc -f3 -b 2500 -q 1 
-o out.m2v

Play around with the options if you succeed.
Especially the "-b n" option (bitrate).

This also looks promissing:
