Video Sequence Editor in Python

Trigger

Use this skill when the user:

• Builds or inspects a VSE / sequencer timeline from a script
• Mentions sequence_editor, strips, sequences, new_effect, COLOR strips, or StripTransform
• Hits AttributeError: 'SequenceEditor' object has no attribute 'sequences' on 5.x
• Hits TypeError on new_effect kwargs (frame_end vs length)
• Renders a sequencer composite whose COLOR cells ignore transform.scale_* after a resolution change
