Jitter supports scenes of up to 120 seconds in length.
To adjust your scene duration:
Hover over the boundary between the white and grey areas of the timeline
When the cursor changes to a double-sided arrow, drag it right to increase the scene's duration (up to the 120s limit)
Alternatively, select the scene layer and opening the Animate tab to specify the duration:
New files are set to 4 seconds by default. If you notice you preview or export stops earlier than expected, check that your scene duration covers the duration of your animations.
✏️ Note: If you need scenes longer than 120 seconds, we recommend exporting each scene separately and using another video editing tool (iMove, Premiere Pro) to stitch them together.
