# SDI in and out

This tutorial covers how to:

- Add an [SDI input](/v1/docs/decklink-input)
- Adjust the gamma curve using the [Color Curves Operator](/v1/docs/color-curves) to increase the contrast of the video
- Add a layer of graphics and scale it
- Use compositing [blend modes](/v1/docs/blend-modes) to blend the graphics with the video
- Add an [SDI output](/v1/docs/blackmagic-decklink-target)
