from the MEncoder man page

Quote:
Only useful with MEncoder. If harddup is used when encoding, it will force duplicate frames to be encoded in the output. This uses slightly more space, but is necessary for output to MPEG files or if you plan to demux and remux the video stream after encoding. Should be placed at or near the end of the filter chain unless you have a good reason to do otherwise.
Remember that mencoder processes filters in reverse order, eg if you place

-vf scale=512:384,harddup

it will first open the harddup filter then the scale filter. If you place...

-vf harddup,scale=512:384

it will first open the scale filter then the harddup one
