Log video is a recording profile that applies a flattened tone curve to keep as much highlight and shadow detail as possible, giving you room to grade the footage later. You should shoot it if you plan to color grade and your camera records enough bit depth, and skip it if you need footage ready to share straight away.
What Log Does
A normal video profile applies contrast and saturation in camera so it looks finished on a screen. Log instead spreads the brightness range of the scene across the available code values using a logarithmic curve. The result looks low in contrast and washed out on a regular display, but it holds more detail in bright skies and dark corners. Different makers have their own versions, and each has its own recommended grading transform.
What You Need to Make It Worthwhile
- Enough bit depth. Ten-bit recording handles the stretching of a flat image far better than eight-bit, which can show banding in gradients.
- A good bitrate and codec, so compression does not break up smooth areas.
- Editing software that can apply a conversion LUT or color management.
- Time and patience for grading each clip.
Exposure Tips for Log
- Check your camera guide for the suggested base ISO for the log profile, which is often higher than the standard one.
- Expose a little brighter than normal as a rough guide, often about one stop, since noise in shadows is more visible once lifted.
- Use a waveform or false color tool rather than trusting the flat image.
- Apply a viewing LUT on the monitor if the camera supports it, so you can judge faces and skies more easily.
- Keep white balance and lighting consistent across clips to make grading faster.
When to Skip It
Log is a poor fit for quick social posts, live events with a same-day turnaround, or any workflow with eight-bit only recording and heavy compression. In those cases a neutral or standard profile with contrast lowered slightly can be cleaner and less risky. In low light, log can also make noise harder to manage because exposure is pushed lower on the curve.
If you are unsure, shoot a short test clip of a scene you know well, grade it, and compare it with a standard profile version before committing to log for a whole project.
FAQ
Is log the same as raw video?
No. Log is a tone curve applied to compressed video, while raw keeps sensor data with more adjustment room, usually in larger files.
Why does my log footage look gray?
That flat look is intentional. It becomes normal once you apply a conversion LUT or grade the clip.
The Short Version
Log video records a flat image that preserves highlight and shadow detail for grading. Shoot it with ten-bit recording, careful exposure and a grading plan, and choose a standard profile when speed matters more than flexibility.
