Get the free plugin for Adobe Creative Cloud, enabling NotchLC support in After Effects, Premiere and Media Encoder. Windows & macOS (Intel & Apple Silicon) supported.
However, acquiring the software responsibly is just as important as understanding its capabilities. The safest route is to obtain the program directly from Blue Marble Geographics—either as a current license or by requesting the legacy installer through official support channels. If cost or licensing constraints are an issue, exploring open‑source alternatives can provide comparable functionality without legal risk.
One of its biggest selling points has always been its versatility. The software supports an enormous number of geospatial file formats—over 300 in recent versions. This capability allows users to work with vector data (like shapefiles), raster data (such as satellite imagery and digital elevation models), and complex LiDAR point clouds all within a single, unified environment.
: Purchasing through authorized resellers can also be a secure way to obtain the software. Ensure that the reseller is listed on the official Blue Marble website.
Detail when you need it. Unlike other mainstream GPU codecs, NotchLC uses variable block size and variable control point bit levels to provide extra detail while allowing greater compression in areas of flatter colours.
NotchLC breaks colour data down into luma and chroma (YUV). 12bits of depth are assigned to luma data, as in many scenarios this is where bit depth is most perceivable. 8bits are assigned to each of the U & V channels.

Rather than specify target bitrates and end up with undetermined quality outcomes, NotchLC takes the reverse approach: during encoding you set a quality level, and the encoder uses the most compression it can while preserving it.

Utilising the modern SSIM measurement method, NotchLC delivers the high-quality results that are needed to be qualified as an intermediary codec. Don’t take our word for it though — read what dandelion + burdock writes in their big, independent 10bit codec test.
