The best way to deinterlace animation???

[parx86]

I'm having some problems deinterlacing japanese animation. I've found that blending the frames leaves ghosts in high motion areas, so I tried to use the deinterlace filter in VirtualDub. The option to "discard 1st frame" seems to do the best deinterlacing, but it automatically resizes my video to 640x240.....I put the resize filter on after it, and resized it back to 640x480, using the precise bicubic setting, but the video loses a considerable amount of quality from shrinking it down and stretching it back out again, especially the subtitles. Is there any way to "discard 1st frame" without resizing the video. Or is there a better way to do this?

Use Smart Deinterlacer, or better, use Inverse Telecine. Doom9 has a guide on IVTC (Under 3.x -> nandub), so you could have a look at it.

Thanks, that smart deinterlace filter in VirtualDub did the trick

I checked the field only differencing, compare color channels instead of luma, use cubic for interpolation, and motion map denoising boxes, set the motion threshold on 3, left all other settings as default, it came out beautiful, high motion scenes were especially smoother

A motion thresold of 3 is very strong! You should try higher values of thresold, high enough so that interlacing artifacts are still removed and yet the video is not blurred too much. Usually, I try never to go below 15.
