Motion compensated is the only one which makes sense: These are the needed steps (and they allready can be done with the mjpeg-tools...) 1. deinterlace to native frame-rate (PAL:50 Hz/NTSC 59.9xxHz) (with yuvdeinterlace or "mplayer -vf tfields=1:1" if you do not need too much quality but speed...) 2. change framerate (with yuvmotionfps or yuvfps) 3. scale (with yuvscaler or y4mscaler) 4. reinterlace (with y4minterlace) OK, here an example which gives very fluent motion (could probably be better if using yuvmotionfps...): lav2yuv some_PAL.dv |\ yuvdeinterlace -d |\ yuvfps -s 50:1 -r 60:1001 |\ yuvscaler -O SIZE_640x480 |\ y4minterlace -i b |\ your_favorite_encoder... This can be done from NTSC to PAL, too (But at least I do not like to do so, as NTSC material generaly looks bad.) You only need to change the frame-size and -rates... 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.
