Introduction
Color grading is the phase of post-production most frequently underestimated in both time and cost. A common misconception among filmmakers new to the process is that grading is a linear transformation applied uniformly across the film. In reality, professional color grading involves building individual node structures for every shot, creating secondary qualifications to isolate specific elements, ensuring scene-to-scene and cut-to-cut continuity, developing and iterating on a creative look in collaboration with the director and cinematographer, and then rendering multiple deliverable versions for different distribution platforms. A 90-minute independent feature with a thoughtful creative grade typically requires 180 to 270 hours of colorist time before deliverables. Understanding this number at the budget stage prevents the compressed timelines and unsatisfying compromises that result from under-allocating time and money for finishing.
What This Tool Calculates
The core metric in this estimator is hours per finished minute of content, which varies by grade complexity. A basic color correction targeting a clean, neutral image uses approximately 0.5 hours per finished minute: that is 45 hours for a 90-minute feature. A creative narrative grade with intentional looks, secondary qualifications, and scene-to-scene refinement uses approximately 1.5 to 2.5 hours per finished minute: that is 135 to 225 hours for the same 90-minute feature. VFX-heavy projects with complex compositing integration, where each shot requires unique node structures to match CG elements to the plate, can exceed 5 hours per finished minute. The estimator applies a deliverable multiplier because creating multiple versions (SDR, HDR10, Dolby Vision, theatrical DCP) requires rendering, QC, and often additional node work for each version beyond the primary grade.
The Formula and How It Works
Example one: a 90-minute independent feature shooting in LOG on a Sony VENICE 2, targeting a theatrical release with both SDR and HDR deliverables. Narrative feature grade tier at 2.5 hours per finished minute plus a 35% deliverable multiplier for two versions equals approximately 303 colorist hours. With one colorist working 8-hour days, that is approximately 38 working days, or about 7.5 calendar weeks. Example two: a 30-minute documentary episode for streaming, basic color correction tier. At 0.5 hours per finished minute for a single SDR deliverable, that is 15 colorist hours, or roughly 2 working days. Example three: a 5-minute prestige commercial with multiple stylized looks, heavy retouching, and three deliverable versions (broadcast, digital, social). Music video tier at 3 hours per finished minute with a 60% multiplier for three deliverables equals approximately 24 colorist hours across 3 to 4 working days.
Real-World Examples
The Color Grade Tier Reference
Basic color correction covers primary adjustments: exposure correction, white balance normalization, lift-gamma-gain adjustments, and basic continuity matching. This is appropriate for corporate video, event coverage, and budget-constrained documentary work. A creative narrative grade adds intentional stylization, secondary color qualifications, targeted skin tone work, scene-to-scene look development, and DP collaboration. This tier represents the standard for independent features and premium documentary. VFX-heavy and episodic grading adds multi-layer node structures for each shot, CG integration matching, HDR tone mapping passes, and the review cycles that come with delivering work to network or streaming platform technical specifications. Music videos and commercials occupy their own tier because of high iteration rates: client-facing review cycles often involve dramatically different looks across multiple concepts, multiplying the raw grading hours.
Revision Rounds and Their Cost
| Detail | Value |
|---|---|
| Every revision round adds approximately 25 percent of the base grade time to the total. | |
| A film that takes 200 hours for the initial grade and receives two revision rounds requires approximately 300 hours total before final delivery. | |
| This is not an inefficiency or a failure: revision is how the creative process works. | |
| The director and cinematographer see the grade on a calibrated monitor in a controlled environment and make creative decisions they could not make from memory or from an uncalibrated review. | |
| Structuring client agreements to include a defined number of revision rounds, with a clearly communicated additional cost per round beyond that number, protects both the colorist and the filmmaker from scope creep that erodes the economics of the entire engagement.. |
Pro Tips and Common Mistakes
Pro Tips
- Build the grade schedule around the film, not around abstract time blocks.
- Start with a complete scene inventory that lists every location, time of day, and mood category.
- Group shots by visual continuity first, then by storytelling function.
- This allows you to establish looks efficiently rather than jumping between radically different scenes and re-establishing context constantly.
Common Mistakes
- The most common mistake is conflating the grade session with the deliverable session.
- The creative grade and the technical deliverable preparation are separate workflows.
- Creating HDR, DCP, and broadcast masters from a finished SDR grade requires additional color science work, QC, and rendering time that many budgets omit entirely.
Frequently Asked Questions
How much does color grading cost for a feature film?
Colorist day rates in the US range from $500 to $2,000 for experienced independents and $2,000 to $5,000 or more for top-tier colorists at established facilities. A 90-minute indie feature requiring 200 to 300 colorist hours would budget $40,000 to $150,000 at those rates, with significant variation based on market, experience level, and whether facility overhead is included.
Can I color grade my own film?
Yes, and many low-budget filmmakers do. DaVinci Resolve free version is a professional-grade color grading application that is genuinely used in commercial production. The cost savings are real. The tradeoff is the combination of technical learning curve and the fact that the editor or director grading their own film often lacks the calibrated reference monitor, controlled viewing environment, and fresh perspective that a dedicated colorist brings to the project.
What is the difference between color correction and color grading?
Color correction is a technical process: making footage look natural, accurate, and consistent. Color grading is a creative process: using color to serve the story, establish mood, differentiate time periods or narrative states, and create a specific visual identity. Professional workflows do both, typically in that sequence: correct first, grade second.
How many monitors does a professional colorist need?
At minimum, a dedicated reference monitor calibrated to the target colorimetry (P3 for HDR, Rec.709 for SDR) and a control surface such as a DaVinci Resolve Speed Editor or full panel. A second client-facing monitor allows the director to see the grade without looking at the same monitor the colorist is working on. A broadcast monitoring scope (waveform, vectorscope, parade) is essential for technical compliance work.
Start Calculating
Enter your finished runtime, grade complexity tier, number of colorists, revision rounds budgeted, and the number of deliverables you need to create. The estimator returns total colorist hours, working days, and a calendar week estimate. Use these numbers to set realistic expectations with your director, line producer, and distributor, and to budget appropriately for what is often the last major cost center in the post-production pipeline.
