One scene. Different moments.
A timing rehearsal for Google Vids. Change when each line appears; keep the picture in place.
Edits stay in this tab. Reloading restores the original.
Timing rules & controls
Select an object to move to its start. The slider moves in 0.1-second steps; focus it and use the arrow keys for a precise boundary check. Change the wording or interval, then choose Apply timing. Downloads use the applied version, not an unfinished edit in the fields.
Each interval includes its start and excludes its end. The first headline ends at 4.0 seconds and its replacement starts there. Move the first end to 5.0, then inspect 4.5 to see a collision. Move it to 3.0 and inspect 3.5 to see a gap. Reset restores the authored plan.
A PNG keeps only the current flattened picture. The CSV preserves the four text intervals for manual entry in an editor; it is not a Google Vids project. This exercise has no audio, animated transitions or export-failure detection.
