GoPro's 'Log Shooting' and 'GP-Log Encoding'

What is "Log" in Video?

"Log" in video shooting formats refers to a shooting format with a wide dynamic range. When shooting videos in Log encoding format, it allows more flexible image adjustments in post-production compared to regular videos.

If you're familiar with digital cameras, you might think, "Isn't this similar to RAW?" Well, it's a bit different.

While maintaining the basic video structure, it's a format that hasn't yet added the "color" flavor.

Log-shot videos are processed in post-production (video editing phase) using "Look Up Tables (LUTs)," which apply color presets to the video.

GoPro's Log Format

GoPro introduced support for Log format for the first time in the HERO12 series¹, referred to as "GP-Log."

HERO12's "10-bit Log encoding" saves footage in a "low-contrast, desaturated" state compared to videos shot in regular video formats, assuming color grading in post-production.

Therefore, if you do not plan to perform post-production or color grading, it's better not to shoot in GP-Log format.

Advantages and Disadvantages of Shooting in Log Format with GoPro

Advantages

The biggest advantage of shooting in Log with GoPro is the ability to achieve professional-grade video quality. Despite being compact and lightweight, GoPro can produce high-quality footage.

Normally, achieving such high-quality video would require larger, more professional equipment, making GoPro's capability quite remarkable.

Disadvantages

The main disadvantage is that the footage assumes color grading in post-production.

For professionals who regularly perform post-production or have the knowledge, this may not be an issue. However, for those without such expertise or equipment, it can be challenging.

If you're using GoPro to shoot action scenes and quickly upload them to social media, considering the additional effort of color correction, shooting in regular formats may be more practical.
