Questions
Frequently asked questions
Is the safe zone an official fixed YouTube template?
No. YouTube UI can vary by device and experiment; this is a conservative planning guide.
Does the tool edit my video?
No. It provides a visual reference for placement in your editor.
Should captions always stay on one line?
Not necessarily. Keep lines short and verify that multiple lines remain within the guide.
