# Converting Logarithmic to Linear

You can output your film scans to video once you have completed the film grading. There are two general workflows you can use to convert logarithmic images to linear ones:

- Using the Render Viewing option
- Creating manually a Log-to-Lin conversion LUT

To convert logarithmic images to linear ones using the Render Viewing option:

1. Use the same project and the same source footage.
2. Switch to Lin mode. See Setting Logarithmic or Linear Mode.
3. Colour grade the footage for video.
4. In the Render > Local menu, enable Viewing in the Rendering group, and then adjust the black, white, and gamma as needed.
5. Render the files in the correct video resolution. See Rendering Shots.
   NoteWhen Render Viewing is ON, the output render format is set automatically to 8-bit BMP files.
6. Play out the rendered frames to record them on an appropriate VTR.

To convert logarithmic images to linear ones by manually creating a Log-to-Lin conversion LUT:

1. Use the same project and the same source footage.
2. Switch to Lin mode. See Setting Logarithmic or Linear Mode.

   When you switch to Lin mode, a Log-to-Lin conversion LUT is applied to the images automatically.

3. If needed, access the Input LUT menu and adjust the parameters of the default Log-to-Lin conversion.
4. Switch off monitor calibration (since the final render will also be seen on a monitor) and turn off any Print LUTs.
5. Use the Render Output menu to adjust the white, black, and gamma as needed.
6. Colour grade the footage for video.
7. Render the files in the correct video resolution. See Rendering Shots.
8. Play out the rendered frames to record them on an appropriate VTR.
