That's why it is so slow... If you look into the papers dealing with that topic, you may find that even sparse MV-fields are called optical-flow-fields, sometimes... The techniques used are the same than in plain MV-search. You just have to apply some additional constraints which will allow the field to be more smooth and check for invalid vectors a little bit better... I personaly think it is mainly more Sound(TM) than MV-"estimation" other then that it's mainly synonymous... ;-) cu Stefan - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

If neither ./bootstrap or ./autogen.sh are provided then you can try this: autoreconf -f -i to recreate the ccnfigure script. > I tried it last year, TOOoo slow!

Compressor knows about interlaced video and can encode it. It (Compressor) is not a deinterlacing tool, that is correct. So maybe if you have interlaced video it should remain interlaced during the conversion process. > yuvmotionfps is not bad (not perfect, it makes some ghosts) but I > think it's the best free soluce (but I don't manage to compil it anymore :-( If I have some free time this weekend maybe i'll look at it - but recreating the ./configure script might be all that is needed Steven Schultz - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

If you look into the papers dealing with that Slow is almost an inadequate word ;) Yes, processing each pixel intead of 16x16 or 8x8 blocks slows the process down. looks good though if you have the patience ;) Cheers, Steven Schultz - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
