    how to scale a transparent png image

    Hello

    I want to superimpose a company logo across the whole of a short film. Upper lefthand corner.

    I prepare a png of the logo and I make the white background transparent (using Gimp).

    I import this into a bin and then place it on the timeline via the source monitor. On a track at the very top of the timeline, spanning all clips.

    The round logo shows up full size, filling the screen, except for the corners. The transparency works fine ie the white background is transparent. You can see the video behind.

    Now all I have to do is reduce it in size and move it to the top lefthand corner position.

    I step into the clip and apply the Blend: 3D Warp effect.

    Which is when it all goes wrong. I now have three separate tracks when I step in. The top two contain the png and, above that, a matte track.

    There is a padlock icon which I click. Thinking that it will lock the image and the matte together when I apply the scaling.

    But I cannot get the image and the matte to scale together. I have tried a few different ways and each time it ends up a mess.

    Would reallly appreciate some advice. I am relatively new to Media Composer so I could be overlooking something really basic.

    Many thanks.

    Hi,

    Richard Gooderick:
    Now all I have to do is reduce it in size and move it to the top lefthand corner position.

    I step into the clip and apply the Blend: 3D Warp effect.

    Rather than stepping in, just go into effects mode and use the resizing parameters available within the matte key effect itself.

    ciao,
    Carl

    Re: how to scale a transparent png image

    I get great results by using the the size and positon feature on the transform tab, right in margue. A full screen graphic easily reduces to the fit on a name key. Its eay to postion because you are working full screen at the time, with the video in th bacground.

    Re: how to scale a transparent png image

    Why go to Marquee when the imported matte is directly adjustable anyway?  Carl's approach is the simplest and most direct, and you also position easily with video in the background in full screen mode.

    I go with Avid FX,  To my eyes it scales significantly better than a matte key. Long durations are easier.

    FWIW if you get the logo in a decent format (vector EPS's or AI's) you get even better results for keys with AvidFX.

    Please make Enter Slip and Enter Slide mode selection available for mapping (to buttons or KB) via the Command Palette.
