Unclear cost change records: project loss of control starts with ambiguity.
In commercial video production, cost changes are almost inevitable. Weather changes on shoot days, actor schedule adjustments, temporary location changes, or adding an extra subtitle version in post-production can all alter the budget. However, most project disputes do not stem from the changes themselves, but from the changes not being clearly documented. The brand assumes it was confirmed verbally, while the production team assumes it was mentioned in an email, leading to conflicting claims during final settlement.
To mitigate this risk, a cost change documentation mechanism must be established from the first day of project initiation. The focus of this mechanism is to clearly document the reason, content, scope of impact, and approver for every change. The standard for determining the mechanism's effectiveness is that, after project completion, any expense can be traced back to a corresponding change record, and the record includes the decision basis and confirmation time.
If records are missing, subsequent acceptance and reuse will face issues. For example, if the final video needs modification, it is impossible to determine the modification cost without records of which shots in the original footage were added and which scenes were temporarily replaced. More seriously, if copyright or portrait rights are involved, unclear change records can lead to legal risks.
The trigger conditions for cost changes must be defined during the project initiation phase.
Do not wait until the shoot to discuss changes. During project initiation, the production team must define which situations constitute cost changes and which are normal execution deviations. Generally, the following situations should be considered cost changes:
- An increase or decrease in shooting days.
- Changes in the number of scenes or locations.
- Replacement of actors or key crew members.
- Adjustments to the equipment list, such as adding cameras or lighting.
- New editing versions, color grading styles, or sound design added in post-production.
- Changes in delivery formats or platform requirements.
The standard is that any adjustment affecting manpower, equipment, locations, or post-production workload should trigger a change record. The production team should provide a change trigger list at the project kickoff meeting, which serves as the execution basis once confirmed by the brand. If the list does not cover a certain situation, both parties should agree on a supplementary process, such as retroactive recording after written confirmation by the project manager.
The risk is that some changes seem minor, such as shooting two extra takes of a shot, but they can cumulatively increase post-production editing and color grading time. If unrecorded, the post-production team cannot justify the increased hours. An exception is if the project uses a fixed-price contract that explicitly allows for certain flexibility; in this case, these adjustments may not constitute a cost change, but the reasons must still be recorded for post-project review.
Use a standardized form to record every change on set.
The set is a high-risk area for cost changes. Weather, lighting, actor conditions, and location constraints can all alter the plan on the fly. It is recommended that the production team use a standardized change log form, filled out by the line producer or assistant director. The form should include at least the following fields:
- Change ID, incrementing sequentially.
- Date and time of the change.
- Description of the reason for the change, such as weather, actors, location, or equipment failure.
- Details of the change, such as adding a scene or cutting two shots.
- Estimated cost impact, including crew, equipment, location, and post-production.
- Name of the client approver and the method of approval, such as WeChat, email, or signature.
- Relevant attachments, such as reference images or communication logs.
The form should be completed in duplicate, with the brand and the production team each retaining an electronic copy. After the shoot, the forms should be compiled into a change log to serve as an attachment for settlement. The standard for determining the validity of a form is that any new expense can be traced to a record on the form, and the record includes explicit approval from the brand's designated representative.
The risk is that on-site approvals are often given verbally or via WeChat, making it difficult to gather evidence later. It is recommended that the production team immediately send a written confirmation via email or a project management tool after each change is approved, noting the change ID. If the brand does not reply, it cannot be considered as implied consent, and a reminder should be sent. The exception is that if a change is urgent and affects the shooting schedule, the production team may proceed first, but must issue a supplementary record on the same day; otherwise, the costs will not be covered later.
Cost changes during the post-production phase must be recorded separately.
Cost changes in post-production are often overlooked because they are not as visible as those on set. For example, if the brand requests an additional vertical video edit, an adjustment to the color grading style, or a remix, these will all increase post-production hours. It is recommended to record post-production cost changes separately from production changes, as post-production changes typically involve different teams and software environments.
Post-production change records should include the following:
- A description of the change request, such as adding a 15-second social media version.
- The stages involved, such as editing, color grading, sound, subtitles, CGI, and AIGC.
- An estimate of the workload, such as requiring an additional two working days.
- Changes to the deliverables, such as adding a new master file.
- Copyright implications, such as new music or font licensing.
The criterion is that post-production change records can clearly distinguish which work falls within the original contract scope and which is new. If the original contract includes multiple revisions, the maximum number of revisions must be clearly defined, with any excess considered a change. The risk is that many post-production revisions are iterative, such as repeated color grading adjustments, making it difficult to define them as a specific number of changes. It is recommended to agree that each revision is based on formal feedback via email or a project management tool, and verbal feedback does not count toward the revision limit.
An exception is that if post-production changes involve AIGC-generated content, the copyright and usage scope of the generated assets must be additionally recorded, as AIGC asset licensing may differ from traditional filmed assets. In this case, it should be recorded separately, and it must be confirmed whether the brand holds commercial rights.
Include the cost change record as one of the deliverables during acceptance.
Commercial video project acceptance typically focuses on the quality of the final video, but the cost change record should also be included as a deliverable. During acceptance, the brand should require the production team to provide a complete change list, covering both production and post-production. This list should include all change numbers, reasons, content, cost impacts, and approvers. Without this list, the acceptance is incomplete.
Acceptance actions include:
- Verifying whether the change list is consistent with the contract terms.
- Checking whether each change has an approval record from the brand.
- Confirming whether the change costs are within the budget and if any excess has additional approval.
- Archiving the change list as a basis for project review and future reuse.
The standard for determining whether acceptance is passed is that every item in the change list corresponds to the content of the final video. For example, if there is a specific special shot in the final video, a corresponding additional shooting record should be found in the list. If it cannot be found, the brand has the right to request supplementary explanations from the production team; otherwise, payment will not be settled.
The risk is that some production teams may only provide a lump sum without an itemized breakdown. Brands should insist on a detailed breakdown; otherwise, they cannot judge the reasonableness of the costs. An exception is that if the project uses a fixed total price with few changes, the list can be simplified, but it must at least include change order numbers and confirmation records.
Cost change records directly impact asset reuse and copyright management.
After a commercial video is completed, the assets and final cut may be reused, such as for different platforms, different events, or secondary editing. Cost change records play an important role in this regard. If the change records are clear, the brand can know which assets were shot additionally, which scenes have special authorization, and which music or fonts require extra payment. This helps avoid copyright risks during reuse.
The specific action is to require the production team to provide an asset inventory linked to the cost change records upon project delivery. For example, if a shot was added, the asset inventory should mark the change order number corresponding to that shot. This way, the brand can quickly determine whether the asset has additional authorization for subsequent use.
The criterion is that the asset inventory and change records can corroborate each other. If there is a shot in the asset inventory without a corresponding change record, but it exists in the actual shoot, it indicates the records are incomplete. The brand should request supplementary records; otherwise, it may affect the commercial legality of the assets.
The risk is that some production teams may transfer full copyright of the assets to the brand, but unclear change records could render some assets unusable. An exception is that if the project explicitly agrees that all assets are bought out and the contract includes a copyright transfer clause, then the change records mainly affect cost accounting and do not impact copyright ownership.
Cost change records do not apply to all projects, and their boundaries must be judged.
Not all commercial video projects require complex cost change records. For projects with small budgets, short cycles, and simple content, such as a 15-second social media short video, a complete change form may not be needed. In this case, a simplified method can be adopted, such as recording key changes in the project group chat, but confirmation records must still be retained.
Situations where cost change records do not apply include:
- Projects with a fixed total price where the contract explicitly includes multiple revisions, and the scope of the revisions is very small.
- With an in-house production team and no external vendors, cost changes do not involve contract settlements.
- For purely template-based videos, such as those automatically generated using AIGC tools, the cost of changes is extremely low.
The standard for determining applicability is that if a single change may incur costs exceeding 5% of the total project budget, or involves legal issues such as copyright, portrait rights, or venue permits, it must be recorded. If the change only affects internal man-hours and incurs no additional costs, it can be recorded verbally.
The risk is that simplified records may lead to later disputes. It is recommended to keep at least one written record, including the reason for the change and the person who confirmed it, even if the full form is not applicable. The exception is that if the project uses agile collaboration, such as weekly iterations, change records can be integrated into weekly reports, but the impact of the change on costs must still be clearly stated.
The next step is to start with a change log template.
In commercial video production, cost change records are a crucial part of project management. It is recommended that brands work with the production team to create a change record template at the start of the next project, clearly defining the trigger conditions, the person responsible for filling it out, and the confirmation process. The template can be simple, but it must include the change number, reason, content, cost impact, and the person who confirmed it.
During project execution, spend 10 minutes each week reviewing change records to ensure nothing is missed. After the project ends, archive the change log along with the final video and assets as part of the project assets. This not only reduces the risk of the current project but also provides a reference for similar future projects.
If the project involves complex shooting conditions or post-production needs, you can consult a professional production team, such as ONCE, which offers video planning, shooting, editing, color grading, sound, delivery, and content asset management services to help brands establish a more standardized change record mechanism. However, remember that any service requires a clear contract and communication to be effective.
