ASF at a glance
ASF

It is useful for preservation and controlled legacy playback.
For current browser and consumer delivery, MP4 or WebM are generally better choices.
JSON at a glance

It is ideal for payloads, configuration, manifests, exports, and machine-readable documents that need to be easy to parse programmatically.
Use it when interoperability and structured automation matter more than comments or document-style readability.
