If work increases obviously budget increases that depends on scope of work. It varies shot by shot. If any possibility how much we can manage in live shoot that also supports to reduce budgets in VFX.

You have to live within a budget. If you're hiring a director, in the interview if their "vision" exceeds the budget they might not be the director for you. If you've hired them, they knew the budget, now they're asking for more because their "vision" expanded, say no. If it's an independent movie, ask them to raise the difference. The fact is, all this should be hashed out during the hiring process, no later than preproduction. Once filming starts, your director should live into the budget agreed to, to make the film.

Here's a concise summary of cost-effective visual solutions: Prioritize Practical Effects: Makeup, prosthetics, miniatures, stunts Leverage Digital Tools: Open-source software, stock footage, motion graphics Creative Problem-Solving: Location scouting, lighting techniques, collaboration Post-Production Optimization: Efficient workflow, cloud-based rendering, color grading, sound design
