Salvage DVD-sourced video with frame blending?

[nat932]

Hi all,

I've got this video here which has some pretty bad frame blending I haven't been able to fix.

The video must've originally been something like 24 fps, or 25 fps, progressive. However, when it got authored to this DVD, it was encoded as 29.970fps, interlaced, top field first - causing the frame blending.

I tried simply deinterlacing the source with QTGMC and attempted to use ExBlend. The settings I tried (mostly default) seem to detect some of the blending but most of it is still untouched.

I'm thinking maybe ExBlend isn't the right script to use, as I'm not even sure what the original framerate is, and the pattern seems to change throughout the video from what I've seen.

I've attached a ~30 second clip. The full video is 1h37m long.

I would greatly appreciate any guidance on how to resolve this.

Did you try srestore() yet?

Thanks lordsmurf, appreciate the quick response.

I ran into some error messages while trying to use SRestore previously (due to some other scripts being outdated), that's why I didn't try it before. I got it working now, and it seems to detect most blended frames:

What I'm currently doing is first performing a simple bob deinterlace (double framerate), then running SRestore with no additional settings. There's still some blended frames, but it's better than nothing.

I don't think I've found the right settings for this scenario though. Simply running SRestore sets the fps to 28.743 which seems really unconventional, and leads me to think I need to set the framerate myself. I tried setting the framerate to 23.976, 24 and 25, but all of those seem to confuse SRestore, and it ends up looking worse than just not setting the framerate at all

Is there a method to find out what the original framerate was?

as a side note: is it just me? When I download the sample from above firefox wants to save a .mp4 not a .mkv file
