    What would be a good way to create videos clips for Youtube in HD using Virtualdub2? What would be a good way to make good, crisp video clips for Youtube? I have some animated shows that want to make clips or do I just resize it using Nearest Neighbor, Lanzcos3,etc.?

  2. Probably the best upscaler for VirtualDub is Infognition's Super Resolution.

    But you can upscale for free with AviSynth's nnedi3_rpow2(), maybe with aWarpSharp() and Sharpen() before and/or after. Learning AviSynth is tough though.

    No kidding man. AVISynth feels like studying a foreign language at times.....

  4. Avisynth is a pain in the "butt".
    By the way I don't like the result of this "resizer", it works great with anime and materials like that.

    You have to be careful with real world video. Even if you make edges really sharp there will be no detail between them. So everything looks like plastic. That is, you're not creating HD detail, just enlarging the frame while keeping edges sharp and free of aliasing artifacts.

    Agree!
    Overall it has a "plastic" look.

    Source:


    720 upscale.


    Code:
    nnedi3_rpow2(2, cshift="Spline36Resize", fwidth=1234, fheight=720)
    aWarpSharp(depth=5)
    Sharpen(0.2)

  7. But compare that to more tradition resizing, like Lanczos3:

    Yes!
    This is the "out of the frying pan into the fire" kind of situation.

    Should I just do the two resizes or should I just learn AVISynth?

    Should I just use my PowerDirector program to cut the clips? Or should J just do the standard Nearest Neighbor and Lanzcos resize?

  11. Personally I really don't care about resizers because many modern TV's this days can handle upscale/downscale just fine and much better than software solution. My monitor is a Sony Bravia 47W802A, it has a X-Reality-whatever video processor that does a great job upscaling and enhancing low resolution sources and it's a TV I'm not giving up so soon.

    This is a 2012 TV model, imagine what they can do today.

    There isn't a one size fits all for upscaling/downscaling video content, you have to analyze how many damage it will cause in a case by case scenario. Over here I use "BicubicResize" to upscale and "BilinearResize" to downscale, but again this is a general example, I have good results with BilinearResize to upscale som VHS sources, it depends. There are cases that I use "PointResize" that is very "raw" and blocky and latter I do a post production with some filters to smooth it out and give the finish I want like "Dehalo_alpha".

    Some people uses "nnedi3_rpow2", I don't like it because it gives a "plastic" look, it looks fake to me. But this is a personal taste, you need to test different resizers and decide for yourself what looks best for you.

    Did you try jagabo's earlier suggestion of using Infognition's Super Resolution in VDub (or VDub2)? It's free now.

  13. I've done a test with this infognition software and it looks like a Lanczos3+heavy sharpness, it show a lot of noise. I don't have any other SD material to test it out, but it will give an idea.

    MARVEL Super Hero vs Street Fighter(point)(720p)
    Code:
    PointResize(960, 720)
    TemporalSoften(13, 14, 18, scenechange=15, mode=2)
    MARVEL Super Hero vs Street Fighter(nnedi3)(720p)
    Code:
    nnedi3_rpow2(2, cshift="Spline36Resize", fwidth=960, fheight=720)
    aWarpSharp(depth=5)
    Sharpen(0.2)
    MARVEL Super Hero vs Street Fighter(bilinear)(720p)
    Code:
    BilinearResize(960, 720)
    Sharpen(0.8)
    MARVEL Super Hero vs Street Fighter(bicubic)(720p)
    Code:
    BicubicResize(960, 720)
    Sharpen(0.8)
    MARVEL Super Hero vs Street Fighter(VEnhancer)(720p)
    Just selected the 960x720.

  14. Super Resolution filters won't work well with this type of material since they analyze sub-pixel motions to tease out more detail. When that fails they fall back on more traditional resizing/sharpening.

    nnedi3 was originally written for anime. Typically hand painted cells, shot on film, then digitized. So the source is moderately well antialiased.

  15. Looks like Super Resolution doesn't work well with anything, it's just my personal impression.
    I've uploaded a few more samples but I don't use any resizer, the settings are the same, just changed the source.

    So even cartoons won't work with the resizer? I wanted to make clips from cartoon shows but I guess I would just I have to stick with traditional resizing.

  17. nnedi3 is great with cartoons. Far better than your TV, media player, or computer can do.

    Super resolution like Video Enhancer uses won't work well.

    I guess I will have to just find that and use it in Virtualdub.

    Edit: How do you upscale and downscale with Nnedi3?
