I have an interlaced 29.97fps (according to Gspot) NTSC dvdr of a movie that was originally broadcast in UK and recorded to tape. At some point, I think someone made a Pal dvd, and then tried to convert it to ntsc. In the first 20 minutes, the video has a ghostly or trailing look, and overall has incremental motion. The first problem is improved by deinterlacing. I posted two samples from the dvd at Videohelp and someone diagnosed the problem as:
The first video is an interlaced PAL broadcast of a progressive film source that was captured with the fields out of phase. Then every 5th frame (except every 1000th) was duplicated to create 29.97 fps. The second video is similar to the first except the fields were not captured out of phase.
Since these were from the same dvd, I'm not sure why they have different issues, and how I'd apply the solutions.
He suggested some fixes in Avisynth (TDecimate for the whole, and added commands for the out-of-phase video), but I don't know how to use Avisynth. Any suggestions with more conventional software (Tmpgenc Express) or freeware?
