Prepared with AI assistance for Genflow Editorial · Report a factual correction
A producer should be able to open a video budget after delivery and explain every difference from the original plan. Which shot changed route? Which paid attempts produced nothing usable? How much did the second format add? Did the team consume its contingency, or simply spend less time elsewhere?
The estimate-to-actual ledger below answers those questions with one project record. It connects final files to source shots, calculates each expense, preserves the estimate, and records what changed. Copy it into your team’s finance or project system. This ledger is an editorial worksheet, not a Genflow feature.
It is intended for producers, creative leads, and project owners who must authorize work before generation begins. All figures are hypothetical planning units (PU). They demonstrate arithmetic, not vendor prices, market rates, expected retries, or production results.
The completed record: 879 estimated, 1,087 spent
Start with the project’s closing balance. The following sections reproduce every number.
| Control field | Planning units | Meaning |
|---|---|---|
| Original baseline | 879 | Estimated work under the base route |
| Named reserve: interaction-shot fallback | 240 | Additional capture and edit allowance |
| Authorized budget | 1,119 | Baseline plus reserve |
| Fallback scenario total | 1,119 | Full attempt allowance followed by capture |
| Illustrative actual spend | 1,087 | Completed expenses in the hypothetical closeout |
| Baseline variance | +208 | Actual minus original baseline |
| Reserve drawn | 240 | Eligible fallback expenses activated |
| Undrawn reserve | 0 | The entire named allowance was used |
| Remaining authorized budget | 32 | Authorized budget minus actual spend |
The project finishes within its authorization but above its baseline. Both statements matter. The 32 PU left over does not mean the fallback reserve was unused: that reserve was fully consumed, while other work produced a net saving.
Assign a producer to maintain the ledger, a creative lead to accept shots and edits, and a budget owner to release reserve or approve additional spending. These are responsibilities for the reader’s project, not claims about a project conducted for this article.
What the money must deliver
This example commissions two files from four shared shots. Both files use the same selected footage; the vertical version requires additional reframing.
| Final file | Specification | Shot sequence and timeline duration | Acceptance responsibility |
|---|---|---|---|
| D1 — product overview | 24 seconds, 16:9, music and text | S1: 6s; S2: 6s; S3: 8s; S4: 4s | Creative lead |
| D2 — vertical cut | 12 seconds, 9:16, music and text | S1: 3s; S2: 3s; S3: 4s; S4: 2s | Creative lead and channel owner |
Approval requires the intended action, stable product identity, correct text, cleared source rights, and the agreed export specification. The vertical crop must preserve the necessary product detail throughout motion.
S4 is a title card assembled in post-production. It is part of both deliverables, but it has no generation attempts.
Allocate footage without purchasing it twice
Each source shot receives one cost record, regardless of how many edits contain it. Reuse does not create another generation charge.
For reporting costs by final file, this example allocates shared work by timeline use. Every shared shot appears in D1 for twice as long as in D2, so its expense is assigned two-thirds to D1 and one-third to D2. Shared preparation, review, licensing, and delivery use the same agreed project ratio. The vertical reframing row belongs entirely to D2.
This allocation is a reporting convention, not an assertion that runtime determines production difficulty. A team could choose another documented rule. The essential check is that allocation shares total 100% and do not increase the project total.
The base ledger contains 819 PU of shared work and 60 PU of D2-only reframing:
- D1: 819 × 2/3 = 546 PU.
- D2: 819 × 1/3 + 60 = 333 PU.
- Project total: 546 + 333 = 879 PU.
The fallback allocation is 706 PU to D1 and 413 PU to D2, totaling 1,119 PU. Actual allocation is 674.67 PU to D1 and 412.33 PU to D2, totaling 1,087 PU after rounding. These are allocations of existing expenses, not extra debit rows.
Copy the ledger’s assumptions with its numbers
Keep this header attached to the cost rows:
| Field | Example entry |
|---|---|
| Project and estimate version | Product overview / estimate v1 |
| Scope | D1 and D2 as specified above |
| Cost basis | Planning units; internal labor included |
| Rate source | Hypothetical inputs for this article |
| Estimate owner | Producer |
| Reserve release owner | Budget owner |
| Evidence locations | Attempt records, time entries, purchase records, file approvals |
| Change policy | Preserve v1; append dated decisions and revised forecasts |
The exercise assumes no taxes, refunds, or additional subscription charges. In a real project, record applicable taxes within the corresponding purchase row, and use your organization’s documented subscription allocation. Do not charge the same usage again because it also appears on a subscription invoice.
Routing assumptions that drive the rows
| Shot | Required behavior and video risk | Base route | Attempt limit | Fallback |
|---|---|---|---|---|
| S1 | Gentle camera orbit; silhouette must remain stable over time | Reference-based generation | 2 × 6 billed seconds | Stop and re-estimate if neither works |
| S2 | Macro slide; surface detail must remain stable through movement | Reference-based generation | 3 × 6 billed seconds | Stop and re-estimate if all fail |
| S3 | Hand closes a lid; contact and final position must be physically coherent | Generated interaction | 4 × 8 billed seconds | Film the action |
| S4 | Exact title and end-card wording | Post-production graphics | 0 | Correct in the edit |
These are project-specific allowances, not acceptance-rate predictions. S3 carries an explicit fallback because temporal contact errors can invalidate the action even when individual frames look convincing.
For model selection, use the separate AI video model acceptance test. Bring its relevant workflow evidence into your estimate rather than introducing an open-ended model trial inside the delivery budget.
One hypothetical paid attempt produces one candidate and bills the full stated duration. Generation costs 2 PU per billed second. Operator handling takes 0.25 hours per attempt at 40 PU/hour. Shot review takes 0.10 hours per S1 or S2 attempt and 0.20 hours per S3 attempt at 50 PU/hour.
Thus S3’s four attempts create three distinct expenses: 64 PU of generation, 40 PU of handling, and 40 PU of review. The fallback does not erase any of them.
The debit rows: base, fallback, and actual together
Each expense belongs to one mutually exclusive bucket:
- P: Brief, source preparation, workflow setup, and coordination.
- G: Provider generation charges only.
- O: Running attempts and handling candidates.
- Q: Shot inspection and final-file review.
- E: Assembly, repair, graphics, audio finishing, and reframing.
- D: Export, technical quality control, and archive.
- X: External purchases, licenses, and storage.
Internal time appears under its activity, even when one person performs several activities. Do not add another general labor or overhead percentage covering the same hours.
The external capture package includes its supplier’s operator and equipment. It excludes the team’s editing and review, which remain in E and Q. Reserve is authorization held outside these expense buckets.
In the quantity column, values appear in base / fallback / actual order. Hours are decimal hours: 0.10 hours is six minutes.
| Row | Bucket and expense | Quantity: base / fallback / actual | Hypothetical rate | Base PU | Fallback PU | Actual PU |
|---|---|---|---|---|---|---|
| P01 | P — preparation and coordination | 3 / 3 / 2.5 hours | 40/hour | 120 | 120 | 100 |
| G01 | G — S1 generation | 12 / 12 / 12 billed seconds | 2/second | 24 | 24 | 24 |
| G02 | G — S2 generation | 18 / 18 / 12 billed seconds | 2/second | 36 | 36 | 24 |
| G03 | G — S3 generation | 32 / 32 / 32 billed seconds | 2/second | 64 | 64 | 64 |
| O01 | O — S1 handling | 0.5 / 0.5 / 0.5 hours | 40/hour | 20 | 20 | 20 |
| O02 | O — S2 handling | 0.75 / 0.75 / 0.5 hours | 40/hour | 30 | 30 | 20 |
| O03 | O — S3 handling | 1 / 1 / 1 hours | 40/hour | 40 | 40 | 40 |
| Q01 | Q — S1 inspection | 0.2 / 0.2 / 0.2 hours | 50/hour | 10 | 10 | 10 |
| Q02 | Q — S2 inspection | 0.3 / 0.3 / 0.2 hours | 50/hour | 15 | 15 | 10 |
| Q03 | Q — S3 inspection | 0.8 / 0.8 / 0.8 hours | 50/hour | 40 | 40 | 40 |
| E01 | E — shared edit, repair, sound, S4 graphics | 4 / 5 / 5 hours | 60/hour | 240 | 300 | 300 |
| E02 | E — D2 reframing | 1 / 1 / 1.25 hours | 60/hour | 60 | 60 | 75 |
| Q04 | Q — final-file review | 2 / 2 / 2 hours | 50/hour | 100 | 100 | 100 |
| D01 | D — exports, technical checks, archive | 1 / 1 / 1 hours | 40/hour | 40 | 40 | 40 |
| X01 | X — project music license | 1 / 1 / 1 license | 30/license | 30 | 30 | 30 |
| X02 | X — project storage allocation | 1 / 1 / 1 allocation | 10/allocation | 10 | 10 | 10 |
| X03 | X — S3 capture package | 0 / 1 / 1 package | 180/package | 0 | 180 | 180 |
Bucket subtotals provide a second arithmetic check:
| Bucket | Base PU | Fallback PU | Actual PU |
|---|---|---|---|
| P | 120 | 120 | 100 |
| G | 124 | 124 | 112 |
| O | 90 | 90 | 80 |
| Q | 165 | 165 | 160 |
| E | 300 | 360 | 375 |
| D | 40 | 40 | 40 |
| X | 40 | 220 | 220 |
| Total expenses | 879 | 1,119 | 1,087 |
The base scenario budgets nine paid attempts and 62 billed seconds. The fallback scenario retains all nine attempts, adds the 180 PU capture package, and adds one edit hour costing 60 PU. Its incremental requirement is therefore 240 PU.
The actual column is a constructed closeout: S1 uses two attempts, S2 uses two, and S3 exhausts four before moving to capture. That is eight attempts and 56 billed seconds. Preparation takes half an hour less than estimated; vertical reframing takes a quarter-hour more.
Release the fallback as a recorded transaction
Before starting, set S3’s stop condition at four paid attempts or 48 minutes of shot review, whichever is reached first. If no candidate meets the contact and end-position requirement, the producer stops generation and asks the budget owner to release the named fallback allowance.
The release record identifies S3, the rejected output IDs, the reason for switching, and the approved incremental costs:
| Reserve transaction | Incremental PU |
|---|---|
| Activate X03 capture package | 180 |
| Increase E01 from four to five hours | 60 |
| Fallback reserve draw | 240 |
No fifth attempt is included. If capture cannot meet the requirement, or its quote exceeds the allowance, the next decision is a new authorization or scope change.
S1 and S2 have their own attempt caps but no funded replacement route in this example. Reaching either cap without usable footage also pauses work for a revised estimate. A reserve for S3 is not blanket permission to spend on any unresolved shot.
Where Genflow is used, its public AI video generator page describes reusable workflows containing prompts, references, model choices, and output logic. Its image-to-video page describes keeping source images and motion notes with reusable inputs. Reference the relevant workflow and output IDs from the ledger; maintain costs, reserve approvals, and reconciliation in the team’s finance or project system.
Read variance without treating reserve as a saving
Use the original baseline for production variance:
Baseline variance = actual expense − baseline estimate.
Here, 1,087 − 879 = +208 PU.
Variance percentage = (actual − estimate) ÷ estimate × 100.
Here, 208 ÷ 879 × 100 = +23.66%. An estimate of 100 and actual of 120 would display as +20%.
When the estimate is zero, report the amount and mark the percentage N/A — zero estimate. A new 180 PU expense against a zero row is +180 PU, not an infinite percentage. Even when both values are zero, leave the percentage unavailable.
Reserve drawdown follows eligible, authorized transactions. It is not automatically the positive baseline variance. In this example:
- Fallback capture and extra editing: +240 PU, charged to reserve.
- Preparation: −20 PU.
- S2 generation, handling, and inspection: −27 PU.
- Vertical reframing: +15 PU.
- Total baseline variance: 240 − 20 − 27 + 15 = +208 PU.
Remaining authorized budget is 1,119 − 1,087 = 32 PU. Remaining reserve is 240 − 240 = 0 PU. The difference comes from unrelated net savings, not unused contingency. A negative remaining authorized balance would indicate spending beyond the recorded authority.
Close the project by changing the next estimate
AI assisted the source reading, writing, and arithmetic checks for this article. The example is hypothetical; it represents no customer test, benchmark, production result, or expert human review.
At closeout, attach the approved D1 and D2 file versions, reconcile all debit rows to time and purchase records, and preserve the original estimate alongside the actual column. Confirm that shared footage allocations still total 100%.
Then write a short decision against each meaningful variance:
| Evidence from this hypothetical closeout | Update for the next comparable workflow |
|---|---|
| S3 consumed four attempts and still required capture | Price capture as the default; retain generation only as a separately authorized experiment |
| S2 needed two attempts rather than three | Retain the observation with its references and settings; one example does not establish a reliable future allowance |
| D2 needed 15 extra minutes | Check moving crop boundaries earlier and revise the reframing estimate |
| Preparation used half an hour less | Identify which setup steps were reusable before reducing future hours |
Finally, assign an owner and date to each update, record the closing balance, and freeze the ledger. The next producer should inherit the changed routing decision, its cost, and its evidence—not merely a lower headline budget.
