| There's an effect that can be seen applied to some logos animations or, for instance, in the title credits of the movies which makes a slow and subtle zoom in effect to a text. Is there a filter for Virtualdub that can do this? I already have the a video with my logo, but with just a fade in effect. Thanx. |

| I only know of an indirect way to do it. Create the logo on a canvas the same resolution as the main video. Use a solid RGB colour (used green 0, 255, 0) for background that will be designated as transparent when used with the logo filter - save image as bmp. Load the saved image in VirtualDub and press 'Ctrl c' 'Ctrl v' to make the desired number of frames. Save as uncompressed video (should be 24 bit). Close and restart VDub - load the uncompressed video. Select the Zoom filter. Set output width and height same as input (mine was 576 320) Set the x y co-ordinates for placement (I used the centre of the frame 288 160) and set the zoom factor (500). Export as image sequence, bmp files. Verify that the green background is still 0,255,0. Close and restart VDub. Load the main video and select 'Logo filter 1.7b2'. Check the box for 'Animation sequence'; select the first .bmp file in the previously saved sequence - insert the transparency colour value (RGB) and insert a value if required in the 'Tolerance' box to remove artefacts.. Set desired Starting frame, Duration and Loop (1,1) Select a compressor and save the new avi. Sample, about seven seconds in: http://www.mediafire.com/?70tb73gyqqobdwd http://postimage.org/ |

| malky's method sounds great for bitmap overlays, but if you want to zoom a full frame video, (text on black background for instance), Ben Greenwood's Motion filter works well for zooming and panning: http://lags.leetcode.net/filters.html and FadeFX is great for, well, fading FX http://home.earthlink.net/~tacosalad/video/fadefx.htm |
