Original planning exercise; not a measured provider result.

1. Source duration (seconds):

   ________________________________________________

2. Source constant frame rate:

   ________________________________________________

3. Desired slowdown factor:

   ________________________________________________

4. Output duration = source duration × slowdown factor:

   ________________________________________________

5. Delivery frame rate:

   ________________________________________________

6. Approximate output frames = output duration × delivery frame rate:

   ________________________________________________

7. Model and other settings held constant:

   ________________________________________________

8. Contact range / occlusion range / cut range:

   ________________________________________________

9. Exported duration and measured frame rate:

   ________________________________________________

10. Visible failure and next change:

## Worked starting point

2 seconds × 4 slowdown = 8 seconds. At 24 fps: about 192 output frames. At 60 fps: about 480. Boundary counts and fractional rates can differ.
