View Full Version : Interlace Frames on Film Video (Problem)

I keep having this problem when backing up my DVDs. It seems that I am the only one with this problem since I have not seen other people posting any similar to this.

I have some DVDs that have a few interlace frames of video within the progressive film video (shrek, contact, Mr nice guy...etc.) Not all Movies have this problem. I see the interlace lines even on the original DVD. It does not really bother but it is there. Sometimes when I see a new movie for the first time I see something weird then go back with the DVD step by step and there it is the interlace frame. It is only for one frame but it repeats like 10-15 times throughout the movie.

The movie "Traffic" has about 40 of these frames, usually is at the beginning of each chapter. This is the most I have encounter on one movie.

In order for me to get them out of my backup I must deinterlace the whole movie but the problem is that CCE slows down to about 1/3 the speed when deinterlacing.

If you analyze the Video on DVD2AVI it will switch for a fraction of a second from film to NTSC. This fraction of a second is not that DVD2AVI is faulty but that indeed the video changed to NTSC interlace for that frame. This is the only evidence that I know I am not crazy, the interlace frame it is there.

My question is? then do people notice this but don't care? or am I too picky?

I am using 32'' Plasma TV connected to component to DVD player.

It sounds to me like you have done something wrong somewhere along the way. It sounds like there are some errant RFF flags in your original video (at the chapter points?). If you create a .D2V file of your VOBs and use the FORCE FILM option, this should strip out any errant RFF flags. Then frameserve the video to VirtualDub to view where the interlaced frames used to appear and see if they are still there.
