Let's walk through the expression step by step.

The given expression is:

\[
\frac{1}{2} \left[ \frac{3}{4} (5 - 9)^2 + \frac{1}{4} (8 - 12)^2 \right]
\]

### Step 1: Simplify the expressions inside the parentheses.
- \( 5 - 9 = -4 \)
- \( 8 - 12 = -4 \)

### Step 2: Square the results.
- \( (-4)^2 = 16 \)
- \( (-4)^2 = 16 \)

Now the expression becomes:

\[
\frac{1}{2} \left[ \frac{3}{4} \cdot 16 + \frac{1}{4} \cdot 16 \right]
\]

### Step 3: Perform the multiplications.
- \( \frac{3}{4} \cdot 16 = 12 \)
- \( \frac{1}{4} \cdot 16 = 4 \)

Now the expression becomes:

\[
\frac{1}{2} \left[ 12 + 4 \right]
\]

### Step 4: Add the terms inside the brackets.
\[
12 + 4 = 16
\]

Now the expression becomes:

\[
\frac{1}{2} \cdot 16
\]

### Step 5: Perform the final multiplication.
\[
\frac{1}{2} \cdot 16 = 8
\]

### Final Answer:
\[
\boxed{8}
\]
