DVCPRO25 format has a constant bitrate of 25 mbps. The 4:1:1 is also mandatory for that format (DVCPRO50 is 4:2:2 and DV is 4:2:0). The video I get with this command is correctly formated and well recognized by my player. However, some artifacts severe degrade the quality of the image. Deinterlacing is not a good option either because, altough by this way I don't get artifacts, the quality of the image is degraded by the deinterlacing process.
