Masking concepts

---

---

SUMMARY

• • • Masks are used to isolate specific areas of an image instead of working on the entire frame
      

---

• • • There are two main types: the ones we create (rotos) and the ones derived directly from images (keys)
      

---

• • • A thoughtful decision must be made about which type is the most suitable for the need
      

---

• • • Watch out for your project Format (aka resolution) before you start making masks, or you could end up having to re-do them entirely
