Shooting Ratio: What It Means, Why It Matters, and How to Stop Wasting Media

The Number That Determines Your Hard Drive Bill

Shooting ratio is the relationship between how much footage you record and how much footage ends up in the finished film. A 10:1 ratio means you recorded 10 minutes of footage for every 1 minute that appears on screen. A 20:1 ratio means you recorded 20 minutes per finished minute.

For a 90-minute feature at 10:1, that is 900 minutes, or 15 hours of recorded material. At 20:1, it is 30 hours. The difference between those two numbers determines how many hard drives you need during production, how long your data wrangler spends backing up media each day, and -- most significantly -- how many hours your editor spends ingesting, logging, and reviewing footage before they make a single cut.

Shooting ratio is a pre-production decision disguised as a production behavior. Productions that don't set a ratio target before the first day of shooting typically drift toward high ratios by default, because recording additional takes costs nothing in the moment and feels like creative insurance. The downstream cost arrives in post, where every extra hour of footage adds editing time that costs money and delays delivery.

This post explains how to set a realistic ratio target for your project, covers industry norms by genre, and shows how to use the Shooting Ratio Calculator to connect your ratio target to concrete storage and post-production cost estimates.

The genre ratio benchmarks below draw from the American Cinema Editors' post-production survey data and workflow documentation from the Editors Guild Local 700.

How Shooting Ratio Is Calculated

The formula is straightforward:

Shooting Ratio = Total Recorded Minutes / Finished Film Runtime Minutes

For a 90-minute film with 22.5 hours of recorded footage: 22.5 hours x 60 = 1,350 recorded minutes / 90 finished minutes = 15:1 ratio.

In practice, shooting ratio is tracked per shooting day using the camera report. The data wrangler or script supervisor notes the total recorded duration at the end of each day. Running totals allow the producer and director to monitor whether the production is trending above its planned ratio before the situation becomes expensive.

The Shooting Ratio Calculator takes your planned shooting days, average daily recording time, and finished runtime to project your total footage volume, storage requirements, and implied editing hours.

Industry Norms by Genre

The table below shows typical shooting ratios across production types. These are industry averages -- individual projects vary significantly -- but they provide a realistic pre-production planning baseline.

The documentary category deserves special attention. A 50:1 ratio on a 90-minute documentary means 75 hours of recorded footage. At 4K ProRes HQ (approximately 120GB/hour), that is 9TB of raw media before redundant backup copies. A production shooting 50:1 without planning for that storage volume will run out of media mid-production.

The Downstream Impact: Storage and Editing Time

Every extra point of shooting ratio has two costs: storage and editing time.

Storage cost is calculable before the shoot. Take your planned shooting ratio, multiply by your finished runtime, and multiply by the data rate of your recording codec. The Storage and Footage Calculator performs this calculation for any combination of camera, codec, resolution, and frame rate.

A 90-minute film at 15:1 shooting ratio recording 4K ProRes HQ (approximately 120 GB/hour): 15 x 90 minutes = 1,350 minutes = 22.5 hours x 120 GB/hour = 2,700 GB = 2.7 TB of raw media. With a 3-2-1 backup strategy (three copies, two media types, one off-site), you need approximately 8.1 TB of total storage across all drives. At current SSD pricing, that is $400 to $700 in media cost.

The same film at 25:1: 25 x 90 = 2,250 minutes = 37.5 hours x 120 GB = 4,500 GB = 4.5 TB raw, or 13.5 TB total storage. That is $700 to $1,100 in media. The ratio increase from 15:1 to 25:1 adds $300 to $400 in storage cost and roughly 15 additional hours of footage the editor must review.

Editing time is harder to calculate precisely but follows a consistent pattern: every additional hour of footage adds 2 to 4 hours of editor time in logging, reviewing, and selecting from takes. On a production paying an editor $400 to $600 per day, 15 extra hours of footage adds $400 to $800 in editing cost, plus the additional time added to the delivery schedule.

Three Examples: Ratio Targets Set in Pre-Production

Example 1: Micro-budget narrative feature, 85-minute runtime

Director's plan: 15-day shoot, 2 hours of recording per day. Implied footage: 30 hours. Ratio: 30 x 60 / 85 = 21:1. Too high for a tightly scripted drama with an editor on a fixed deal. Using the Shooting Ratio Calculator, the producer modeled a 12:1 target: 12 x 85 = 1,020 minutes = 17 hours. That meant 68 minutes of average recording per shooting day -- achievable by limiting takes to 3 per setup unless a specific creative or technical problem required more. The director agreed to the target and tracked daily totals on the camera report.

Example 2: Character documentary, 75-minute runtime

A one-person documentary crew following a subject over 30 shooting days. No script. Ratio control was impossible in the traditional sense -- the director couldn't predict when the subject would do something filmable. The planning approach was storage-first: project the maximum affordable ratio and calculate the media budget accordingly. At a 40:1 target on a 75-minute film: 40 x 75 = 3,000 minutes = 50 hours of footage. The Storage and Footage Calculator calculated media requirements and the production budgeted 12 TB of total storage across production and post. The actual ratio landed at 38:1.

Example 3: Commercial production, 30-second spot

A branded content agency shooting a 30-second commercial with a 2-day production schedule. Target ratio: 8:1. At 30 seconds of finished content, 8:1 means 4 minutes of recorded footage -- very low. In practice, commercial shoots operate with highly precise scripts and strict shot lists, making ratio control achievable. The agency used the Shot List Generator to build a precise shot list with one primary take and two backup takes per setup, which naturally constrained the ratio without requiring on-set monitoring.

How to Set and Monitor Your Ratio Target

Step 1: Determine your finished runtime. For a scripted feature, this is your target cut length, typically 85 to 110 minutes. For a documentary, use your intended delivery runtime.

Step 2: Enter your runtime and format into the Shooting Ratio Calculator and run the calculation at three ratio scenarios: your intended ratio, a 1.5x overrun (the most common production drift), and a 2x overrun. Look at the storage and editing time implications at each level.

Step 3: Set a per-day recording target. Divide your total implied footage by your number of shooting days to get a daily recording budget. Brief your director and DP on this target before production begins.

Step 4: Include ratio tracking in the camera report. The script supervisor or data wrangler notes total recorded duration at the end of each day. A running total against the target is reviewed by the producer at the end of each shooting week.

Step 5: Set a ratio ceiling -- a number above which an on-set conversation is triggered between the director, producer, and first AD. A ratio ceiling of 1.5x the target means: if you're at 21:1 when the plan was 14:1 at the midpoint, a creative and logistics conversation happens before the next shooting day.

Step 6: After production, use the Post Production Timeline Estimator with your actual footage volume to recalculate the editing phase duration. A ratio significantly above projection extends the edit and may require renegotiating the editor's deal.

Pro Tips and Common Mistakes

Pro Tip: The most effective ratio control tool is a precise shot list. Productions that use the Shot List Generator to plan setups with a defined number of takes per setup consistently run closer to their ratio targets than productions that improvise coverage on the day. A shot list does not constrain creativity -- it channels it toward intentional choices rather than reflexive additional takes.

Pro Tip: Brief your actors on take count expectations before the shoot, not during. Some actors perform better knowing they have 3 to 5 takes to find the performance. Others feel pressured by a take count and perform worse. Understanding which performers need latitude and which need structure lets the director set ratio-appropriate expectations before the first setup.

Pro Tip: For documentary productions where ratio control is unrealistic, focus ratio planning on the interview and controlled sequences rather than the observational material. If 60% of your documentary runtime comes from interview coverage, controlling the ratio on interviews from 20:1 to 12:1 meaningfully reduces total footage volume even if observational material remains unconstrained.

Common Mistake: Recording continuously in lieu of using the camera's record button deliberately. Some operators leave the camera rolling during setups, blocking rehearsals, and between takes as a "safety net." This inflates the ratio without adding usable footage and compounds across a full production into dozens of hours of non-selectable material that the editor still has to ingest.

The fix: Establish on-set discipline around the record button. The camera rolls when the first AD calls "rolling" and stops when they call "cut." Between setups, the camera should not be recording. This is basic production discipline that directly controls ratio.

Common Mistake: Planning storage based on the target ratio without accounting for ratio overrun. A production that plans 12 TB of storage for a 15:1 ratio and drifts to 22:1 will run out of media during production -- one of the most avoidable and disruptive production failures possible.

The fix: Always buy or budget storage for 1.5x your target ratio minimum. Use the Shooting Ratio Calculator to calculate the overrun scenario and confirm your media budget covers it.

Frequently Asked Questions

Does shooting ratio affect the quality of the final film?

Not directly, but it affects the quality of the editorial process. A high ratio gives the editor more material to select from, which can improve performance selection -- particularly on naturalistic or improvised productions. However, high ratios also create analysis paralysis, where editors spend more time reviewing options than making decisions. The films that benefit most from high ratios are those where the editor has the time and budget to fully exploit the additional material. On a micro-budget production with a constrained edit budget, a lower ratio often produces a better edit because the editor spends more time shaping the available material.

What ratio do major studio productions typically shoot at?

Major studio productions vary widely by genre and director style. Action blockbusters with complex stunt sequences routinely shoot 20:1 to 40:1. Drama features from directors known for extensive takes (Mike Leigh, David Fincher on some productions) can reach 30:1 to 50:1. Productions with tight schedules (many superhero films with extensive visual effects requiring precise photography) often run 8:1 to 15:1. Budget does not determine ratio -- creative approach and production style do.

How does high frame rate slow-motion footage affect shooting ratio?

Slow-motion footage recorded at high frame rates (120fps, 240fps) and played back at 24fps creates a time expansion of 5x to 10x. One minute of 120fps recording becomes 5 minutes of 24fps playback. This footage typically represents a small portion of total production but should be calculated separately in your ratio planning. The Slow Motion Calculator helps model the playback duration of any slow-motion recording for ratio calculations.

Is there a standard way to report shooting ratio on a camera report?

Yes. The camera report includes a "footage recorded" field (typically in feet for film, minutes and seconds for digital) that the camera assistant or DIT fills in at the end of each magazine or card. The script supervisor tracks total recorded time against script pages covered each day, which provides the data needed to calculate the running ratio. The ratio is not typically listed explicitly on the camera report but is calculated from total recorded versus total finished runtime.

Ratio Is a Budget Decision

Every additional minute of recorded footage is a cost deferred to post-production. It does not feel like a cost in the moment -- the card has space, the camera is rolling, one more take feels cheap. The Shooting Ratio Calculator makes the deferred cost visible before production begins, when you can still plan for it rather than absorbing it as an unexpected overrun.
