I am working on some simple animations for teaching phonics - taking a word, and animating the letters in sync with the phonemes (sounds) that the letters represent.
In the top left hand corner, I have a rotating cube with my foundation’s logo on it. I’ve been playing with the node editor to get the cube to sit correctly, and managed that fairly easily by putting it in a separate scene, then translating and scaling it, and finally using an alphover node to sit it on my main image:
The only problem is that I want the final product to be in PAL 16:9. While I’m working, I generally set the output format to 1024X576 with pixel aspect 100X100, to give an idea of what the final product will look like on a widescreen TV. So, whenever I switch between 1024X576 and 720X576, I have to readjust the translation node so that the logo sits properly again.
I noticed that there is a math node, which could do the conversion very simply, if I could get the dimensions to feed into it.
Of course, at the moment, it would be simple enough to adjust the x translation value by hand, but eventually, I might add other elements this way, so I’d like to know if relative translation is possible.
Thanks in advance for any ideas.
