Pros
Honestly none. It's a terrible business model and preys on people desperate for work.
Kontras
They don't pay anything upfront unless you pay a penalty (they take a percentage of your fee) from the total, so you're essentially loaning them money for the duration of the project, which could be months. Budgets are insanely low and they expect you to pay your crew garbage rates to compensate. The project managers do literally nothing once the job is "awarded" to you, they do not stand up for you, and will never say no to the client. Instead they play dumb and go, "I don't understand..." They also hoard all of the budget. They once accidentally sent a deck with the full budget outlined and I found out I was literally getting 15% of it to actually make the video. Their clients are unhinged and have unrealistic expectations, probably because they think they are putting 100k into a project but really they are only getting a 15k video back. Quickframe also expects their creators to literally come up with all of the creative, concepts, scripts, etc, none of which is properly compensated. They're essentially glorified middle men who do AB testing.
