QuestStudio | FLUX 3 Video Guide: Test Motion and Sound in One Shot https://queststudio.io/blog/flux-3-video-guide Prepared September 13, 2026 EVENT AND SOUND SCORECARD Event: A felt mallet strikes a suspended copper bell once. Before: Bell still; mallet visible; camera locked. Contact: One visible contact; one audible onset. After: Mallet withdraws; bell moves; ring decays into room tone. PROJECT Model / version / provider: Duration / resolution / audio setting: Reference file / source permission: Review playback setup: TAKE LOG (repeat for every attempt, including failures) Take filename: One approach and one contact? PASS / FAIL No penetration, extra strike, or changing object? PASS / FAIL Single clean ring and no unrequested sounds? PASS / FAIL Visible contact time: Audible onset time (not necessarily the waveform's largest peak): Perceptible sync problem at normal speed? YES / NO Usable beginning and ending? PASS / FAIL Generation cost / review time / finishing time: Reject reason / next single change: Compare picture-only, audio-only, then both. Check playback delay before attributing an offset to the generated file. These are test instructions, not measured FLUX 3 results. FLUX 3 is not currently a QuestStudio model. EXAMPLE 1 One continuous close shot of a small copper bell hanging securely in a quiet sound studio. The camera is locked at bell height. At the beginning, the bell is still and a felt mallet is visible to its right. The mallet approaches, strikes the lower side of the bell once, then withdraws fully. The bell swings gently after contact. A single clear bell ring begins with that contact and decays naturally into quiet room tone. Warm practical light, believable metal and felt surfaces. Keep the contact point visible. No music, speech, extra strikes, cutaways, or camera movement.
