Scaling an interlaced DVCPRO25
|[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]|
Hi, I'm trying to change the aspect ratio of a DVCPRO25 from anamorphic 16:9 to lettterbox. To do this, I have to scale it, and then expand with black bands. As the source is interlaced I use the "il" filter (i know that "scale" has an interlaced option, but by using it i don't get better results). This is my best try: mencoder original.dv -of lavf -lavfopts format=dv -ofps 25 -vf il=d:d,scale=:432,il=i:i,expand=:576,harddup -oac pcm -ovc lavc -lavcopts vcodec=dvvideo:format=411p:ildct -o converted.dv However I get some strange artifacts when I play it in a interlaced display. ?Can anyone tell me if there is a better way to achieve this?. Thank you.
