Documenting a change means recording what was different, what caused the difference, and what effect you expect. A change log turns “I improved it” into evidence that a reader can follow.
This lesson is part of SPM subjects and learning resources. It builds on explaining narrative and media choices in a storyboard.
What makes a change worth documenting?
A change is worth documenting when a viewer would notice it. A new opening, a different colour scheme, a shorter clip or a removed sound all count.
Tiny fixes such as a spelling correction can stay out of the log. The log is for decisions about the concept.
Worked example: an invented concept
Imagine a thirty-second animated poster about a school recycling week. Version one opens on a full screen of text listing the dates. A cheerful jingle plays throughout, and the bins appear only in the last five seconds.
After a classmate watches it, the learner notes that nobody remembered what the poster was about. Version two opens on a close-up of a bin with a bottle dropping in. The dates appear at the end, and the jingle becomes quiet background.
| Element | Version one | Version two | Prompt | Expected effect |
|---|---|---|---|---|
| Opening | Text block of dates | Close-up of bottle dropping into bin | Classmate recalled no topic | Viewer knows the subject at once |
| Audio | Loud jingle all through | Quiet bed, louder on the drop sound | Jingle drowned the message | Key moment gets the attention |
| Dates | First screen | Final screen | Dates felt like a notice, not a story | Dates become the call to action |
Every row names a cause. The prompt column is what separates a log from a list.
A note that shows evidence
Compare two ways to record the same opening change.
Vague: “I changed the start to make it better.”
Evidenced: “A classmate who watched version one could not say the topic afterwards. I replaced the date text with a bottle dropping into a bin, so the topic is clear in the first three seconds.”
The second note has a cause you can point to and a result you can test. It also invites a re-check: show version two to the same classmate and see whether they name the topic.
Keep the log honest
Write the log as you change things, not at the end. Notes written afterwards often invent tidy reasons that were never there.
If a change did not work, record that too. “Quiet jingle made the poster feel flat, so I raised it slightly” is a stronger note than pretending every edit succeeded.
Check yourself
Version one of a short promo shows a long pan across a school field. Version two cuts the pan to one second and starts on students arriving. The learner’s only note says “faster is better”. Rewrite it as a four-part entry.
Answer
Before: a long pan over the field at the start. After: one-second pan, then students arriving. Prompt: a tester looked away during the pan, for example. Effect: the viewer sees people sooner and stays with the story.
The exact prompt is your choice. The test is that every part of the entry names something observable, not a general feeling.
