Newer versions of resizers?

[bsmith1593]

Does anyone know if you can get newer versions of resizers (like Lanczos4 instead of Lanczos3) in VirtualDub without user AviSynth?

[LoRd_MuldeR]

ffvdub (ships with ffdshow).

Note that Lanczos4Resize is not a "newer" (or "better") version of Lanczos3Resize. They are just LanczosResize with different Tap parameters ;)

I always did wonder why so many programs use 3 taps. Is it that much harder to go with 4, like everyone else on this forum does?

Lanczos4 produces a sharper image than Lanczos3, but it also produces more ringing. So you cannot assume that Lanczos4 is generally better than Lanczos3...

Yeah, the reason I made this topic is because I wanted a higher tap version because everyone was saying it was sharper.

In ffdshow (ffvdub) you have a slider to set the number of tabs for LanczosResize, so that should be what you need. Also give SplineResize a try ;)

So if I edit the taps in ffdshow, it will be like that in vdub? And where could I get spline for vdub (non-avisynth)? The reason I don't want to use a resizer in my scripts is because I don't want to resize before I deinterlace (I used blend in vdub, 'cause after telecide and I resize I notice some residual combing/interlacing during motion). I could just blur it, but it blurs it more than blending the fields does.

No! You must use the "ffvdub" filter in VirtualDub. That filter ships with ffdshow, but it is separate from ffdshow's DirectShow part ;)

I used blend in vdub

That's probably the worst deinterlacer you could use. If there is some combing left after the inverse-telecine (IVTC), use something like TDeint in "only process combed frames" mode.

If your video shows a lot of deinterlacing after IVTC, your source probably isn't telecined, but truly interlaced! In that case you need a deinterlacer, not IVTC.

Do you have a link for that filter, 'cause it's not in my vdub? And I used blend after IVTC because other deinterlacers that interpolate damage some progressive frames in the video. It also took away the interlacing without ghosting. You could only see it during motion around her face and like in her mouth. Every time I paused in vdub, the image would smooth out and I couldn't see the interlacing.

Make sure you choose the correct folder when you are asked for the VirtualDub install location during setup ;)

Thanks :D. I think I'll try Spline out too ;)
