Mandem in Disguise: why does the flash feel late, and how do I fix it?
Updated:
Short answer
Use the full 10-second video, not the preview, which compresses the beats. The flash lands at about one second, so place your sound so a beat meets it. Every run is created anew, so the flash may arrive a few frames sooner or later.

Repair it in your editor
- Use the full video rather than the preview.
- Set your sound so one of its beats hits the flash near the one-second mark.
- Silence or lower the video's built-in audio.
Why it slips
Timing is modelled on the viral format, yet the model invents each moment, so the flash can shift by a few frames. The clip isn't timed to a particular post.
Questions people ask
Does the silent download help?
Yes. Only the sound you add will play.
Is a late flash a failure?
No. The render completed normally, so no credits come back.
Which part should I line up first?
The flash. It falls at about one second, so match a beat of your sound to it before anything else.
