    Hey all,
    Let me start with apologizing for my bad English.
    Secondly: this is my very first video-project ever (well, one that is more complicated than only cutting and pasting)... I know almost nothing about video-editing, and I have no professional software/hardware. I am using Windows Live Movie Maker, Windows Movie Maker 2.6, WinMorph, and thinking about using Wax and Zweinstein.

    So, my question: one of the scenes (takes only 2-3seconds) is the picture of a 'question mark' turning 90degrees clockwise. That's it. Nothing more. The picture doesn't need to transform or morph or warp or whatever. Just a turn in 2D.
    (this is the picture I would use: http://www.pittwater.nsw.gov.au/__data/assets/image/0009/53199/Question_mark_alternate.jpg )

    How can I do this? I am coming close with WinMorph by warping the picture from a shape (circle around the sign) to same shape, same place, but turned 90degrees.. but.. can't get the settings right, the pictures keeps deforming a bit, the edges keeps deforming... (even with protective square around it)

    Any other way?

  2. If you rotate, the edges will be black around the white background, unless you key out the video (perhaps you wanted to overlay the question mark onto other video using alpha channel?)

    If you don't care, and just wanted to rotate it, you can use avisynth (free) and rotate()

    Code:
    ImageSource("1.png",0,90,fps=29.97)
    ConvertToYV12()
    LanczosResize(640,480)
    Rotate(angle=0,color=0,start=0, end=90, endangle=90)
    In this example, I resized it smaller just for illustration purposes. (I converted your image to png; for some reason it has problems reading the jpg source)

    Hey Poison, thx for your reply!
    - what is "keying out'?
    - what is 'alpha channel'?

    The aim was making the video of this turning sign on his own, so not overlaying on another video/image. So, the 'whole' background should stay white. Any way to fix this?

    Try this:
    ImageSource("1.png",0,90,fps=29.97)
    ConvertToYV12()
    LanczosResize(640,480)
    Invert()
    Rotate(angle=0,color=0,start=0, end=90, endangle=90)
    Invert()

    The 'color' parameter of Rotate() sets the background color, so all you need is

    ImageSource("1.png",0,90,fps=29.97)
    ConvertToYV12()
    LanczosResize(640,480)
    Rotate(angle=0,color=color_white,start=0, end=90, endangle=90)

  6. I thought Rotate() might have a color option but the computer I was on at the time didn't have Rotate() installed.

    Posideneathray has given you the correct answer all you need to do is create another video with a white screen then overlay your video with the question mark and rotate it. It possible to create the with background movie from a still image, or it can be created entirely in avisynth via the script.

    You don't need to overlay or use a separate background - just add the appropriate color option to Rotate() as I explained.

    One step up in quality would be to layer a 3D question mark (with transparency) on top of the white (or on top of video). For that, I'd use BluffTItler - it easily supports 3D rotation, Extruding, using Text/Fonts as Graphic objects, and Transparency. Perfect for this kind of job.
    Then, you'd just layer the Rendered Blufftitler clip on top of whatever background you want. This could be the "LAYER" command in AVISynth (since it directly and automatically supports RGBA masking).
