Most Costly Beginner Mistake in Modern Post-Production Workflows?

Hey everyone,

I'm an aerial cinematographer, and often my projects involve heavy files straight off cameras like the ALEXA 35 or even a V-RAPTOR XL. I'm always looking to refine my post-production and editing workflows, especially as things get more complex with frame rates and resolutions.

I've been diving into various discussions on optimizing efficiency, things like solid proxy pipelines for dealing with those big codecs and even AI-assisted tools for transcription or rough cuts. Many resources touch on common traps, such as over-relying on automated filler-word removal or completely bypassing proper proxy creation.

From your experience, what do you all see as the single most common and costly mistake beginners make today when trying to implement these modern, faster workflows? I'm trying to avoid any major headaches down the line.
