Why editors want MOV

Many editing and compositing apps import WebM poorly or ignore its alpha channel. ProRes 4444 in a MOV is the industry-standard way to move transparent video between tools.

ProRes files are large by design — they are built for editing, not for the web. Keep your WebM for the website and use the MOV in your timeline.
