I want to make an web application using blender where they will be some predefined video templates, where user can upload the image/video or text of his choice as an input to the template.
Requirement: Dynamically replace the blender objects using some script.
Also, If anybody has idea how fast it would be to do it in real time, currently I am using FFmpeg for this, which is fine but not extensible. And even a small effect requires good amount of code change.
Any blender (headless) speedup/parallelization tips will be appreciated.
Feel free to suggest question edit or in case of duplicacy, will take down the question
