Hi,
I have a VOB file that is PAL 720x576 interlaced and field shifting, at least some part of it. After passing it through telecide(post=false) i get a wonderful clean work (most of it).
A single scene (I hope, I did not check it frame by frame) has some duplicate frames. The pattern looks like 3 good frames and one duplicate, but unfortunately it is something like that:
20 good frames, then 3 good 1 bad for three times, then another x frames good, than 5 times the "three good one bad" pattern and so on. I could not find any logic in that.
I think the source is weird, but it plays smootly. The only explanation i can give is that at the same time there is some written text appearing in the video and that the source video has been badly mixed with the text.
I'm still catching up with all the valuable informations from all the threads and FAQ's and help files, but usually you have to find a pattern to apply the solution.
The solution would be to substitute all the duplicate frames with blends from previous/next frames to retain the same smoothness of the original. I tried to do this with decimate but could not make it because of the missing logical pattern to apply.
I could manually override telecide for those frames, or simply deinterlace the scene instead of teleciding it, but i would like a method to do it automatically without checking the output frame by frame.
Hope this is not a stupid question.
Thanks a lot.
