A high-quality master may be unusable for employees on constrained connections. Agree the essential information and usable alternatives before production is complete.
Define a tested viewing package that preserves meaning across the approved low-bandwidth routes.
Decide what meaning must survive the smaller delivery version
Start with the information the viewer needs, not a target file size. Small labels, dense charts and rapid screen movements may become unreadable when delivery quality is reduced. Identify those elements early so the production treatment can simplify them or provide an equivalent explanation.
Ask the system owner to describe the actual access constraints. Intermittent connectivity, limited data and an older device are different problems. The film package should respond to the known situation rather than assume that a lower-resolution export solves everything.
Test the alternative route as a complete resource
A transcript should preserve the information carried by meaningful visuals, not only the spoken words. If a presenter says the selected option is shown in green, the text needs to identify that option and explain the relevant distinction. Otherwise, the alternative loses the central message.
Where downloads or offline access are proposed, confirm that the approved platform supports them and that access restrictions remain appropriate. The producer should not promise platform behaviour from a file export alone. Have the responsible owner test the actual route.
Keep the versions visibly related. Use a clear title and revision context so employees can tell that the smaller file and text alternative correspond to the same current explanation. A changed instruction should not leave an old low-bandwidth copy circulating unnoticed.
For acceptance, ask viewers using different approved routes to explain the same decision or task. Differences in visual polish are acceptable; differences in essential meaning are not. Record any missing information and correct the relevant version. The commissioning outcome is a usable package under the organisation’s real conditions, not simply a compressed file delivered beside a high-quality master.
Ask who will replace downloaded copies when the instruction changes, rather than assuming a platform update reaches every viewer.

| Essential visual information | Describe necessary visuals in text |
| Available text and download options | Keep alternatives clearly associated |
An illustrative application
Suppose a field team has intermittent connectivity. The organisation tests a smaller delivery file and a useful transcript through its approved system. The transcript describes the decision graphic rather than merely transcribing a speaker who says as you can see. This example is hypothetical, not a Live Images project.
Ask a viewer using the constrained route to explain the same core decision as someone watching the master. Do not promise offline access or platform behaviour until the responsible system owner has tested it.
