Tree Growth Simulation Video

I need to show how this build will adjust the branch structure as discussed so the tree becomes increasingly dense but contained within the frame. The overall shape like the attached. The video will show the tree growing from seed to maturity. The funding application limits the file size of attachments so the video can be less than 20 seconds long. No text or voice-over required, in fact nothing is needed except the tree itself growing with different coloured branches/leaves. To simulate search-within results there will be a string of white highlighted leaves that grow along the branch and form small clusters. We attempted to show this in the simulation video ('Big Forest' with the American woman's voiceover) but the white highlighted items were difficult to see at 1:22, they need to be a bit bigger.) Note that the video does not need all the details as shown in the prototype/simulation videos. Just need the tree to grow branches, sub-branches and sub-sub-branches with leaves populating as the branches grow and becoming increasingly dense until the tree reaches maturity. Key functions include:
1. Search-within highlighted results grow like a trail of breadcrumbs along the branch while forming 2 or 3 smaller clusters on adjacent branches
2. Rotate the object
3. Zoom in and out
(The attached photo of a real tree is the overall shape, the video will show the different colours)
