Video encoding balances quality against file size. Here are key technical principles applied by MediaFetch:
CRF controls visual fidelity. A lower value (e.g., CRF 18) retains higher fidelity with larger file size, while CRF 23 provides a balanced sweet spot recommended for web playback.
The MP4 container stores its index in a "moov" atom. By moving this atom to the beginning of the file, web browsers can begin playing the video immediately without waiting for the entire file to download.
