Sixth Animation: zooming logo

If you would combine all your animations so far you would get a really wild video compilation, but if this was your company’s presentation you would want to present the logo in a more recognizable way. The final part of our compilation will therefore be an animation of the logo that zooms in very slowly. Prepare this one and save it as ‘zoomlogo.avi’. Also prepare a white picture and save it as ‘white.tga’.

We will now use the CROSS effect to first make a rapid transition from black to white, then from white to our logo animation. Finally, a transition to black will conclude the compilation.

Start off by placing black.tga in channel 1 and white.tga in channel 2. Make them both 20 frames long. Select them both and apply a cross effect. The cross will gradually change the resulting image from layer 1 to layer 2. In this case, the result will be a transition from black to white:

Next, add a duplicate of white.tga to layer 1 and place it directly to the right of black.tga. Make it about half as long as the original. Place the logo zoom animation in layer 2 and add a cross effect between the two. At this point, the animation looks like a white flash followed by the logo zoom animation:

The last thing that you need to do is to make sure that the animation will have a nice transition to black at the very end. Add a duplicate of black.tga and apply another cross effect. When you are ready, transform everything into a meta strip:

Assembling everything so far

We’re at the end of our work! It’s time to add some of the compilations that we have made so far and see how our work looks. The most important thing to remember while creating your final compilation is that when rendering your animation, the sequence editor only ‘sees’ the top layer of video. This means that you have to make sure that it is either a strip that is ready to be used, or it should be an effect like ADD that combines several underlying strips.

The foundation of the compilation will be the fluctuating tunnel. Add a some duplicates of the tunnel meta strip and place them in channel one. Combine them into one meta strip. Do not worry about the exact length of the animation yet; you can always duplicate more tunnel strips.

On top of that, place the delayed wireframe cube in channel 2. Add channel 1 to channel 2 and place the add effect in channel 3:

Now we also want to add the solid cube animation. Place it in channel 4, overlapping with the WireFrame animation in channel 2. Add it to the tunnel animation in layer one. This is where things are starting to get a little tricky; if you would leave it like this, the animation in channel 5 (the solid cube together with the tube) would override the animation in channel 2 (the wireframe cube) and the wireframe cube would become invisible as soon as the solid cube shows up. To solve this, add channel 3 to channel 5:

You will often need to apply some extra add operations to fix missing parts of video. This will most likely become apparent after you have rendered the final sequence.

Slide the Sequence Editor window a bit to the left and add the meta strip with the particle/logo animation in it. Place this strip in layer 2 and place an add effect in layer 3. For some variation, duplicate the WireFrame animation and combine it with the add in layer 3:

Now go to the end of the tunnel animation strip. There should be enough place to put the logo zoom animation at the end and still have some space left before it (Figure 45). If not, select the tunnel strip, press TAB and add a duplicate of the animation to the end. Press TAB again to leave meta edit mode.

If there is still some space left, we can add a copy of the solid cube animation. To get it to display correctly, you will have to apply two add channels to it: one to combine it with the particle logo animation and one to combine it with the logo zoom animation:

Here’s the complete sequence:

Conclusion

We are now ready to render our final video composition! To tell Blender to use the Sequence Editor information while rendering, select the Do Sequence button in the Render Buttons window. After that, rendering and saving your animation works like before (be sure not to overwrite any of your AVI of the sequence!).
