Change Track Start Positions

By default, every track begins at the very start of the timeline. However, if your project relies on manual synchronization — for example, aligning an externally recorded audio track with its corresponding video — you may need to shift individual tracks so that their content lines up correctly.

Note: See Synchronization

Setting a custom start position offsets the track horizontally along the timeline, relative to the other tracks. The offset is specified in seconds and can be either positive or negative:

• A positive value pushes the track forward, delaying its start so it begins later on the timeline.
• A negative value pulls the track backward, making it start earlier relative to the other tracks.

Setting a Track's Start Position

Each track has a "Change Start Position" button on its left side (middle button with right arrow and a pipe). To adjust a track:

1. Click the "Change Start Position" button on the track you want to shift.
2. Enter the desired offset in seconds — positive or negative — in the input field that appears. Decimal values can be used for finer control (e.g., 2.5 shifts the track forward by two and a half seconds).
3. Confirm the value, and the track will shift horizontally to its new position.

Because the offset is entered as an exact numeric value rather than dragged by hand, this method allows you to position tracks with precision — which is essential when fine-tuning synchronization down to fractions of a second.

Automatic Position Normalization

The timeline always begins at 0 seconds. If, after adjusting the offsets, none of the tracks start at exactly 0, the start positions of all tracks are automatically recalculated so that the earliest track begins at 0 seconds.

This shifts every track by the same amount, so the relative spacing between tracks is preserved — your synchronization remains intact, only the absolute positions change.

Example: If your tracks start at 2, 5, and 7.5 seconds, they will be normalized to start at 0, 3, and 5.5 seconds respectively. Each track moved back by 2 seconds, but the gaps between them are unchanged.

Note: This also means negative offsets are resolved automatically — a track set to -3 seconds effectively becomes the new starting point, and all other tracks shift forward relative to it.
