Why traditional video editors fall short

The cloud editor problem

Every online video editor forces you to upload your footage to their servers. You lose privacy, wait for processing, and depend on their uptime. Desktop apps are clunky. The middle ground doesn't exist.

Privacy concerns with cloud uploads
Slow processing and network waits
No offline workflow capability
Licensing costs for desktop software
Steep learning curves for CLI tools
