My question is how do i get rid of screen jerk. I know frame rate has a part,feild order has a part and maybe interlace or progressive. those last 2 i have know idea what they mean. most all the avi files i use say there non interlaced and i convert them to dvd mpeg2. but i don't know if there being interlaced in that process or not usually i just set a feild order top or bottom. When a file says 23.976 fps i use 3:2 pulldown allways. if it's 29 fps i use 29 for my output. so how could there be screen jerk from that. canopus asks for a feild order but i don't know the source feild order. TMPEGEnc asks for interlaced or progressive, but only for the source. I use interlace for that. I also have all the good codecs so i don't think that's a problem. Also what does it mean when it says that it stores frames instead of feilds can i change it to feild and it will play back smoothly. I hope this is somthing simple that someone help me out with. THANX Actually i'm not sure if the files i'm useing are iterlaced or not. how can i tell.
