Hi All
Thank you all. For the time being, I am going to stick with the PNG approach as I am short on time to run any new experiments. However, I made a change that reduced the PNG creation time to minutes instead of hours. Basically, I generated all the numbers up to the maximum possible number that I may need, e.g., 0 to 9999 and 0.00 to 9999.99, and then created a soft link for the PNG sequence. That way, I don't have to create a PNG for each frame but instead, create a soft link pointing to the required PNG. This reduced the time and disk space usage by more than 95%. I am happy with that performance, but I have to live with PNG creations outside of Resolve.
As for the map, creating an SVG file and using spline entries worked wonders. I didn't create PNGs for the map animation in the example shown below.
Here is an example of that approach. I know the map animation is a little boring, but since I made changes to the navigation arrow and the orientation.
Again thank you very much for all of your time. If I come across a Resolve based solution, I'll update this thread.
Have a wonderful weekend.
