Hi folks
The past two weeks I have been working on cleaning some progressive wmv using MeguiIVit and Avisynth. After updating Megui, finding additional plugins etc. I managed to input many progressive video files from my HD. I am manually loading the files using the AVS Script Creator in the tools tab. Except for some minor problems it worked really well with denoising and edge cleaning although I had to convert color space frequently.
I am currently working on cleaning up some
saw toothed edges on a wmv fron ANAN-AV featuring rare uncensored video of Hitomi Mizutani. I planned on sharing this with Akiba-Online but a strange phenomenon similar to the ComplementParity issue with interlaced fields being
out of place was introduced in the output file:
On a 29sec, or 870frames long wmv segment
here at 29.970fps that I got from trimming the source wmv in Windows Media File Editor, the output x264 MKV strangely has 873 frames as opposed to the 870 frames in the input file. But furthermore, when playing back the output file frame by frame there are a few times in the 29sec clip where a future frame is displayed transparently on top of the current frame like so:
This artifact is not present in the 29sec wmv input file.
After a frame or two the problem goes away and the image frame picks up from the current frame, thus making the movie stutter at realtime playback.
From what I can see it also looks like the transparent and out of place future frame has the exact same
saw tooth edges as the input file in the very same frame, meaning that it wasn't edge cleaned. This is clearly visible on the guys shirt in the image.
I first encoded the segment using the placebo Avisynth preset and also knocked the CRF down to 0 while increasing the x264 preset to placebo. I didn't touch the Trellis or Denoise in the analysis tab. However I have tried using the default
30fps C: Slower + Light EdgeClean preset along with the default MeguiIVit 480p30fps x264 preset on the same segment and the problem persists. Strangely it isn't constant though since the artifact in question is affecting different frames in different, but what should be identical, encodes.
I have tried encoding segments of a few other wmvs but I can't seem to reproduce the problem - they encode and playback just fine.
Any idea on what may be causing this issue? Or is the wmv from ANAN-AV perhaps corrupted?
