Section 6: Lip Sync and Performance · Lesson 5 of 5 (30 of 45) · 60 minutes · Evidence: Before and after lip sync comparison
A filmmaker’s first version is almost never the best one, and a revision is only a revision if you can show what improved. Today you do what production teams do before a shot is allowed into the film: you test the performance with fresh eyes, compare versions side by side, and either approve the shot or send it back.
Production journal: write your answer below.
What must a filmmaker understand before they can compare versions revise the source or edit and approve the strongest performance?
A comparison lines up two or more versions of the same shot and judges them against the same criteria. The aim is to learn which version serves the scene best and why. Without a comparison, a revision is only a feeling that something is better. With one, you can point to the moment and show it.
You are too close to your own work to see it clearly. A blind review asks a peer to watch versions labeled only with letters, not version numbers, so they cannot guess which one you made last. They score each criterion and write one comment. If three viewers pick the same version, you can trust the result. If they split, the difference between versions may be too small to matter.
A revision is a deliberate change made for a stated reason. Change one thing at a time so you know which change produced which improvement: a new source image, a shorter clip, a different cut. Approval is the decision that a version is good enough for the film. Approve only when the version meets your criteria and you have the records that show where the face, the voice, and every supporting shot came from.
The student compares three versions of Mara’s line. Version A is the baseline: timing 3, stability 2, emotion 2, clarity 3. Version B replaces the portrait with a calmer, closed-lip image: stability rises to 3. Version C keeps B and splits the line into two clips with a reaction shot between them: stability 4, emotion 3, clarity 4. Three peers see versions A, B, and C as X, Y, and Z; all pick C. The student writes that the largest improvement came from the shorter clip, because it ended the drift, and approves version C.
Productions use a review step before material goes into a final cut. It is where an honest comparison prevents a weak shot from slipping through. Study how reviewers organize the step, and decide where the tool helps and where human judgment is unavoidable.
The reviewer collects versions in a folder, labels them neutrally, and plays them one after another at the size they will appear on screen. Reviewers score each version against the same list and write a comment for each score. They discuss differences, choose a winner, and record the reason. If no version is good enough, the reviewer writes what to change and sends the shot back.
The tool can play versions side by side and keep files organized. It cannot tell you whether a performance convinces an audience, and it cannot confirm that your face and voice were authorized. Those two judgments, quality and permission, are the reviewer’s responsibility and are recorded before approval.
As you study, record each decision point in your production journal.
| Decision point | What the filmmaker does | What the tool automates | What still needs human review |
|---|---|---|---|
| Collect and label versions | Gathers each version and assigns neutral letters | Stores and plays files | That every version is complete and records its inputs |
| Review against the criteria | Scores timing, stability, emotion, and clarity for each version | Plays versions side by side | Whether scores reflect the final viewing size and normal speed |
| Choose a winner or send back | States which change caused the improvement | Nothing | Whether the winner is good enough, or whether another revision is needed |
| Archive the approval | Saves the approved file with authorization and generation records | Can save a copy | That records are complete and the disclosure is stated |
Studio task: Conduct blind peer review using timing stability emotion and clarity criteria.
Run a blind peer review in groups of three or four, using each member’s latest version of their shot (or sample versions supplied by your teacher).
Coaching tips. Reviewers describe what they see, not what they think the author meant. Authors listen first and defend later. If reviewers split, ask whether the difference between the versions is large enough to matter to an audience. Keep every review sheet; the comments become the evidence behind your approval decision.
Shot: ______ Versions compared (key): A = ______ B = ______ Criterion | A score | B score | Comment with moment Timing | | | Stability | | | Emotion | | | Clarity | | | Winner and the one change that caused the improvement: ______ Approved version file name: ______ Records kept (face source, voice source, tool record, disclosure): ______
Studio task: Complete the final revision and submit the approved shot with notes.
Complete the final revision of your lip-synced dialogue shot and submit the comparison.
Checklist before you submit:
Explain which revision created the largest improvement.
Deliverable: Before and after lip sync comparison.
Submit the before and after lip sync comparison. The file must use the course naming convention and include enough process evidence to show the student's decisions and revisions.
File name (course naming convention): AIF_S06-L05_before-and-after-lip-sync-comparison_v01_YOURINITIALS
| Criterion | Advanced | Proficient | Developing | Beginning |
|---|---|---|---|---|
| The work addresses the stated story or production purpose. | The approved shot clearly serves the scene’s purpose, and the comparison shows how each revision supported the story. | The approved shot serves the scene’s purpose. | The approved shot only partly serves the scene. | The shot is not connected to the scene’s purpose. |
| The student applies the required method accurately and produces usable capstone evidence. | Comparison covers all four criteria for three or more versions, with moment-specific comments and one-change-at-a-time revisions. | Comparison covers four criteria for two versions with comments. | Comparison is partial or lacks comments. | No usable comparison. |
| The student identifies at least one quality issue and records a meaningful revision decision. | Names the revision with the largest effect and proves it with peer evidence; proposes a next step. | Identifies a quality issue and records a meaningful revision decision. | Records a revision without evidence of its effect. | No revision decision recorded. |
| The work complies with consent rights attribution privacy disclosure and school policy. | Authorization, generation records, and disclosure statement are complete and stored with the approved shot. | Authorization and generation records are stored with the shot. | Records are partial. | No records, or unauthorized face or voice. |
Requirement: Retain authorization and generation records with the final shot.
An approved shot comes with its paperwork. Keep a note of who created or authorized the face, who created or authorized the voice, which tool you used, the date, and the exact wording you will use to disclose that the performance is synthetic. Never approve a shot that places a real person’s likeness or voice in a scene without that person’s written consent. If you cannot complete the records, the shot is not approved.
